This results in more accessories and increased cost.

7. The existing turbine engine uses a starting form of hydraulic starting, and an auxiliary engine must be started before the turbine engine is started.

3) According to each actuating element, a motor drive is arranged, and the scheme reduces energy waste caused by the hydraulic unit to the maximum extent, so that efficiency is utilized to the maximum.

For example, when a turbine engine is started, a motor used by the existing fracturing equipment is driven, the starting motor needs to consume a part of power, and the hydraulic unit also consumes a part of power, so that the energy consumption of the whole equipment is increased; if the motor is used for driving, the frequency converter is used for controlling, point-to-point driving is achieved, waste of energy consumption does not exist, the motor can be powered off after starting is completed, input power of the motor is not needed, and comprehensive and reasonable distribution of energy consumption is achieved.

4) The lubrication, cooling, turbine engine starting and gas supply of the turbine fracturing equipment are all driven by a motor, for example, a 380V power supply is adopted as the power supply, the source of the power supply is wide, and the power supply can be an energy storage battery, a fuel cell, a grid power, a generator and the like, and the high-voltage power of about 10kV of a conventional electric driving well site is not needed, so that the reliability of the well site is improved.

For example, a conventional electric drive wellsite requires the deployment of 4 power generation equipment of a predetermined power capacity, which if the power generation equipment fails, will result in the entire wellsite "breaking down". According to the embodiment of the disclosure, only 1 power generation device with the preset power can meet the electricity demand of the well site, and the plunger pump with the largest energy consumption demand can use clean energy natural gas as fuel. The energy utilization optimization of the fracturing operation is realized, the well site failure rate is reduced, and the reliability of the fracturing operation is improved. Of course, in other embodiments, the plunger pump may also be fueled with diesel fuel. For example, the predetermined power of the above-mentioned power generation apparatus may be less than 1MW, or the predetermined power of the power generation apparatus is greater than or equal to 1MW and less than or equal to 8 MW. For example, a conventional electric drive wellsite requires 4 pieces of electrical equipment with 5.8MW power deployed, whereas according to embodiments of the present disclosure, only 1 piece of power generation equipment with 5.8MW power is required to be able to meet the electrical demand at the wellsite. Of course, the power of the power plant may be adjusted as desired.

Fig. 3A is a schematic diagram of a fracturing apparatus provided by an embodiment of the present disclosure. The direction of the arrows in FIG. 3A is the gas flow direction. As shown in fig. 3A, the fracturing apparatus 1b includes aplunger pump 1 and aturbine engine 2. Theturbine engine 2 is configured to drive theplunger pump 1. One end of theturbine engine 2 is connected with theplunger pump 1 through aspeed reducer 6 to drive the plunger pump to suck in low-pressure fracturing fluid and discharge high-pressure fracturing fluid, i.e., theplunger pump 1 is configured to pressurize the fracturing fluid to form high-pressure fracturing fluid.

For example, as shown in fig. 3A, theradiator 3 is configured to cool the lubricating oil, lowering the temperature of the lubricating oil. As shown in fig. 3A, theradiator 3 is disposed on one side of themuffler 4, for example, theradiator 3 is disposed above theplunger pump 1. Because the height of the vertical part of thesilencer 4 is larger, although the gas exhausted by theradiator 3 in fig. 3A is upward, the gas exhausted by theradiator 3 can be considered to flow toward thesilencer 4, so that the flow speed of the gas outside thesilencer 4 can be increased, and the rapid cooling is facilitated. Theradiator 3 is arranged on the plunger pump, so that the length of a lubricating oil pipeline can be reduced, the space layout is saved, and the whole equipment structure is more compact.

For example, in an embodiment of the present disclosure, referring to fig. 2B and 3A, a lubrication oil line is provided to pass through each lubrication point, connect with thelubrication pump 11, and dissipate heat through theradiator 3. For example, thelubrication pump 11 is driven by the lubrication motor 52.

As shown in fig. 3A, the other end of theturbine engine 2 is connected to an exhaust assembly 49, and the exhaust assembly 49 includes an exhaust pipe 9 and amuffler 4; an exhaust pipe 9 is connected to theturbine engine 2 and configured to discharge exhaust gas. Themuffler 4 is connected to the exhaust pipe 9 and configured to reduce exhaust noise. For example, theturbine engine 2 includes an exhaust pipe 9, and themuffler 4 is connected to the exhaust pipe 9. For example, the aperture of the exhaust pipe 9 gradually increases from a position close to theturbine engine 2 to a position far from theturbine engine 2 to facilitate exhaust gas discharge.

For example, the fracturing apparatus 1b further includes apower source 12, avehicle body 100, and an auxiliary unit 500. With regard to thepower source 12, thevehicle body 100 and the auxiliary unit 500, reference may be made to the previous description of the fracturing device 1a, and the description thereof is omitted.

In some embodiments, for the cooling unit 503, the same as the fracturing unit 1a, theradiator 3 of the fracturing unit 1b is also directly connected with a cooling motor, and the cooling motor is directly driven.

In some embodiments, for the starting unit 501, theturbine engine 2 of the fracturing unit 1b is directly connected with the starting motor 51 and is directly driven by the starting motor 51, as is the fracturing unit 1 a.

In some embodiments, for the lubrication unit 502, the same as the fracturing unit 1a, thelubrication pump 11 of the fracturing unit 1b is directly connected to the lubrication motor 52, and is directly driven by the lubrication motor 52.

In some embodiments, as for the air supply unit 504, the air compressor 13 of the fracturing equipment 1b is directly connected with the air path motor 54 and is directly driven by the air path motor 54, as in the fracturing equipment 1 a.

In some embodiments, for the ventilation unit 505, like the fracturing unit 1a, the ventilation component 14 of the fracturing unit 1b is directly connected to the ventilation motor 55, and is directly driven by the ventilation motor 55.

In some embodiments, at least one of theradiator 3 of the fracturing device 1b, the auxiliary starting of theturbine engine 2, thelubrication pump 11, the air compressor 13 and the ventilation motor 55 is directly connected with a corresponding motor, and is directly driven by the motor.

In the fracturing equipment provided by the embodiment of the disclosure, the executing components such as theradiator 3, the auxiliary starting of theturbine engine 2, the lubricatingpump 11, the air compressor 13, the ventilation motor 55 and the like are directly driven by the motor, and compared with the mode that the motor drives the hydraulic unit, and the hydraulic unit drives theradiator 3, the auxiliary starting of theturbine engine 2, the lubricatingpump 11, the air compressor 13 and the ventilation motor 55, the energy consumption is low, the motor can be powered off when the executing components are not required to be driven, and the comprehensive and reasonable distribution of the energy consumption is favorably realized.

Fig. 3B is a schematic diagram of a fracturing apparatus provided by an embodiment of the present disclosure. As shown in fig. 3B, the fracturing unit 1B1 has theheat sink 3 tilted to facilitate the movement of the gas exhausted from theheat sink 3 towards themuffler 4, as compared to the fracturing unit 1B shown in fig. 3A. For example, the angle of inclination a1 of theradiator 3 is 10-30 ° in order to facilitate the movement of the gas exhausted by theradiator 3 towards themuffler 4 and to facilitate the mounting of the radiator and the lubricating oil line. For example, theradiator 3 is disposed obliquely with respect to the surface of thevehicle body 100. For example, theradiator 3 is disposed obliquely with respect to the axis a0 of theplunger pump 1. For example, the air outlet side of theradiator 3 is disposed obliquely toward themuffler 4.

Fig. 3C is a schematic diagram of a fracturing apparatus provided by an embodiment of the present disclosure. As shown in fig. 3C, the fracturing unit 1b2 has aprotective barrier 151 on the outside of thesilencer 4, as compared to the fracturing unit 1b shown in fig. 3A. For example, theprotective barrier 151 may be provided with lightening holes (not shown in the drawings). The lightening holes in theprotective shield 151 can be referred to as theholes 150 in theshield 15 mentioned later. Theprotective barrier 151 may serve as a protection. Aprotective barrier 151 is provided on at least one side of themuffler 4. For example, thebaffle 151 may be provided on three sides of themuffler 4 except for the side connected to the exhaust pipe.

Fig. 4 is a schematic diagram of a fracturing apparatus provided in another embodiment of the present disclosure. The fracturing unit 1c differs from the fracturing unit 1b in that: theradiator 3 is arranged on one side of themuffler 4. As shown in fig. 4, the gas discharged from theradiator 3 flows toward themuffler 4. That is, theradiator 3 is configured to flow gas discharged therefrom toward themuffler 4. For example, as shown in fig. 4, theradiator 3 is disposed on a side of themuffler 4 away from the exhaust pipe 9. For example, as shown in fig. 4, theradiator 3 is adjacent to themuffler 4.

Since the temperature of the outer surface of themuffler 4 is high relative to the temperature of the gas discharged from theradiator 3, the gas discharged from theradiator 3 can flow toward themuffler 4, so that the flow speed of the gas outside themuffler 4 is increased, thereby achieving rapid cooling and recycling of the gas.

Fig. 5A is a schematic diagram of a fracturing apparatus provided in another embodiment of the present disclosure. Fig. 5B is a schematic diagram of a baffle in a fracturing apparatus provided by an embodiment of the present disclosure. Fig. 5C is a schematic diagram of an arrangement position of a baffle in a fracturing apparatus according to an embodiment of the present disclosure. Fig. 5D is a schematic diagram of an arrangement position of a baffle in a fracturing device according to another embodiment of the present disclosure.

For example, thefracturing apparatus 1d shown in fig. 5A is provided with abaffle 15, as compared to the fracturing apparatus 1c shown in fig. 4. For example, to avoid the influence of the outer surface temperature of themuffler 4 on theradiator 3, abaffle 15 is provided on the outer side of themuffler 4, and thebaffle 15 is located on the side closer to themuffler 4. For example, as shown in fig. 5A, 5C, and 5D, thebaffle 15 is disposed outside themuffler 4 and at least partially between themuffler 4 and theradiator 3. The provision of thebaffle 15 facilitates maximum reduction of thermal radiation.

Referring to fig. 3A, 4 and 5A, in order to facilitate the positional arrangement of theradiator 3, theradiator 3 is disposed on one side of themuffler 4.

As shown in fig. 4 and 5A, theradiator 3 is disposed on one side of themuffler 4 such that the side (air-out side) S0 of theradiator 3 from which the gas is discharged faces themuffler 4, the gas discharged from theradiator 3 is made to flow toward themuffler 4, the flow speed of the gas outside themuffler 4 is increased, and rapid temperature reduction and recycling of the gas are achieved.

For example, as shown in fig. 5B, in order to facilitate the flow of the gas exhausted from theradiator 3 toward themuffler 4, thebaffle 15 includes a plurality ofholes 150, for example, the holes may be configured as circular holes, oblong holes, and the like, and the shape of the holes may be set according to the need, which is not limited herein. The baffle shown in fig. 5B is described by taking thehole 150 as a circular hole. For example, the gas exhausted from theradiator 3 may flow toward themuffler 4 through the holes in thebaffle 15. Referring to fig. 3A, 4, and 5A, theheat sink 3 includes an air outlet side and an air inlet side, which are disposed opposite to each other. As shown in fig. 3A, the upper side of theheat sink 3 is an air outlet side, and the lower side of theheat sink 3 is an air inlet side. As shown in fig. 4 and 5A, the left side of theheat sink 3 is an air outlet side, and the right side of theheat sink 3 is an air inlet side. For example, air enters from the intake side of theradiator 3 and exits from the exhaust side of theradiator 3.

For example, referring to fig. 5A, 5C, and 5D, there is a space between theradiator 3 and themuffler 4, and the exhaust gas side S0 of theradiator 3 faces themuffler 4. The exhaust gas side (air-out side) S0 of theradiator 3 is shown in fig. 3A, 3B, 4, 5A, and 5C.

As shown in fig. 5C, thebaffle 15 is located outside the first side S1, the second side S2, and the third side S3 of themuffler 4. Thus, the exposed high-temperature portion of themuffler 4 is separated from the exterior component, and the influence of themuffler 4 on the exterior component such as theradiator 3 can be reduced. For example, the external components include, but are not limited to, theheat sink 3. Fig. 5C illustrates an example in which thebaffle 15 is provided on both the second side surface S2 and the third side surface S3, the length of the portion of thebaffle 15 located outside the second side surface S2 in the first direction X is greater than the length of the second side surface S2 in the first direction X, and the length of the portion of thebaffle 15 located outside the third side surface S3 in the first direction X is greater than the length of the third side surface S3 in the first direction X. In other embodiments, the portion of thebaffle 15 located outside the second side S2 may have other lengths in the first direction X, and the portion of thebaffle 15 located outside the third side S3 may have other lengths in the first direction X.

For example, in embodiments of the present disclosure, the second direction Y intersects the first direction X. For further example, the second direction Y is perpendicular to the first direction X. For example, the second direction Y and the first direction X are directions parallel to the support surface of the vehicle body. For example, the support surface of the vehicle body is a surface on which various components are placed.

The position of theshutter 15 is not limited to the position shown in fig. 5C. Thebaffle 15 may be provided only outside the first side surface S1 of themuffler 4 as shown in fig. 5D.

As shown in fig. 5C and 5D, the second side S2 and the third side S3 are oppositely disposed.

As shown in fig. 5C and 5D, themuffler 4 includes a fourth side S4, and the fourth side S4 is disposed opposite to the first side S1. For example, themuffler 4 is connected to the exhaust pipe 9 at the fourth side S4.

As shown in fig. 5D, themuffler 4, thebaffle 15, and theradiator 3 are arranged in this order in the first direction X. In some embodiments, to better reduce the heat radiation, the size of thebaffle 15 in the second direction Y is larger than the size of thesilencer 4 in the second direction Y and larger than the size of theradiator 3 in the second direction Y. As shown in fig. 5C, the dimension of the portion of thebaffle 15 outside the first side S1 of themuffler 4 in the second direction Y is larger than the dimension of themuffler 4 in the second direction Y and larger than the dimension of theradiator 3 in the second direction Y.

For example, thebaffle 15 may be made of a metal material, but is not limited thereto, and those skilled in the art may select a suitable material as needed. In some embodiments, thebaffle 15 may comprise a steel plate.

In an embodiment of the present disclosure, referring to fig. 1A, 3A to 5A, themuffler 4 may include a first portion 41 and a second portion 42, the first portion 41 intersecting the second portion 42, e.g., the first portion 41 being perpendicular to the second portion 42.

For example, the bottom surface of the first portion 41 of themuffler 4 is located on thevehicle body 100. Of course, in other embodiments, the side surface of themuffler 4 may also refer to the entire side surface of themuffler 4, in which case, the side surface of themuffler 4 may refer to a portion of themuffler 4 that is not parallel to the supporting surface of thevehicle body 100.

As shown in fig. 6, the fracturing apparatus includes apower source 12, a power distribution unit 60, and an implement 70. For example, thepower source 12 mainly includes grid power, a chemical battery, a generator, hydrogen power generation, and the like. For example, the battery includes at least one of an energy storage battery, an aluminum battery, a fuel cell, a lithium ion secondary battery, and a nickel metal hydride battery. For example, the generator may be a gas turbine or an oil-fired power generation device.

For example, the power distribution unit 60 mainly includes a switch cabinet, a substation, a distribution station, and the like.

For example, the execution unit 70 mainly includes auxiliary units of the turbine fracturing equipment, sand conveying equipment, sand mixing equipment, chemical adding equipment and other equipment requiring power consumption. For example, the turbine fracturing auxiliary unit adopts a motor as a power source to drive components such as complete machine lubrication, cooling, turbine engine starting, air supply and ventilation.

For example, in embodiments of the present disclosure, direct connection of the drive motor to the implement component may mean that there is no hydraulic unit between the drive motor and the implement component. For example, the hydraulic unit includes a hydraulic pump. For example, in embodiments of the present disclosure, the implement components are electrically driven components, rather than hydraulically driven components.

At least one embodiment of the present disclosure provides a fracturing system comprising any of the fracturing apparatuses described above.

Fig. 7A shows a schematic diagram of a fracturing system including a turbine fracturing plant, manifold plant, sand mulling plant, compounding plant, sand transporting plant, sand tank, etc., as described above, in accordance with an embodiment of the present disclosure. For example, sand tanks are used to store and deliver proppant to a sand mulling facility through a delivery mechanism. For example, chemical addition equipment and clean water sources are connected with the mixing equipment to make the fracturing base fluid in the mixing equipment. For example, the compounding equipment can deliver the fracturing base fluid into the sand mulling equipment. For example, the fracturing blender apparatus thoroughly mixes the fracturing base fluid and proppant to form a fracturing fluid, which is delivered to the turbine fracturing apparatus through a manifold. For example, the turbine fracturing equipment pressurizes the low-pressure sucked fracturing fluid to form high-pressure fracturing fluid which is discharged to a wellhead.

For example, any one or more of a chemical feeding device, a sand mulling device, a sand transporting device, and a compounding device may be powered by thepower source 12. The centralized control is carried out through instrument equipment (vehicle-mounted, semi-trailer-mounted and skid-mounted), and the turbine fracturing equipment, the turbine generating equipment, thepower supply 12, the manifold equipment, the sand mixing equipment, the sand conveying equipment, the sand tank and the like can be controlled, so that the centralized control of the turbine-electric driving well site is realized.

Fig. 7B illustrates a fracturing system provided by an embodiment of the present disclosure. For example, as shown in fig. 7B, the plunger pump of at least one fracturing device in the fracturing system is removably disposed and can be removed and replaced with a generator forming part of thepower source 12. Aiming at the problem of electricity utilization at a well site, the quick replacement structure shown in fig. 8 and 9 is designed, so that the turbine fracturing equipment can be quickly changed into turbine power generation equipment, and the function can be converted by replacing theplunger pump 1 into thepower generator 303.

As shown in fig. 7A and 7B, the solid line represents the formulated fracture fluid and the fracture fluid walk diagram; the dashed lines indicate cable control.

As shown in fig. 8, afirst forklift hole 202 is formed in thefirst base 201, so that the plunger pump can be replaced conveniently.

Similarly, as shown in fig. 9, the quick-change structure of the generator mainly comprises agenerator 303, asecond base 301 and a secondfork truck hole 302. When turbine fracturing equipment needs to be changed into generator equipment, theplunger pump 1 only needs to be replaced quickly, thegenerator 303 is replaced quickly, and quick conversion between fracturing operation and power generation operation is achieved. The speed reducer connected with the turbine engine is set to a preset rotating speed, so that the rotating speed of the turbine engine can be reduced to a certain range, the requirement of the plunger pump operation can be met, and the generator can be driven to perform power generation operation. The output cable of the generator can be quickly connected with the control systems on the turbine fracturing equipment and the sand mixing, mixing and conveying equipment in a quick connection mode.

For example, the turbine power generation equipment is used for one-by-one use, the reliability of power supply is guaranteed, and any two turbine fracturing equipment in a well site can replace a plunger pump with a generator through a plunger pump quick-dismantling structure to be used as thepower source 12. In another embodiment, two replaced turbine power generation devices are preferably disposed on each side of the manifold device to facilitate connection of cables. In another embodiment, the two replaced turbine power generation devices are symmetrically arranged about the center line of the manifold device, so that cable laying is more convenient.
