技术领域technical field
本实用新型涉及一种气动输砂撬，用于油气开采中的压裂施工作业。The utility model relates to a pneumatic sand delivery skid, which is used for fracturing construction operations in oil and gas exploitation.
背景技术Background technique
在石油、天然气开采过程中，一般需要将成百上千吨压裂砂或支撑剂打入井下进行增产压裂。In the process of oil and natural gas extraction, it is generally necessary to drive hundreds of tons of fracturing sand or proppant into the well for stimulation fracturing.
目前，压裂砂以袋装或散装形式运到井场。对于袋装砂，需要人工辅助吊车吊运到储砂装置的进砂口，然后在施工过程中通过储砂装置向混砂车供砂，存在作业效率低，工人劳动强度大的问题。对于散装砂，一种方式由砂罐车向混砂车供砂，往往只能适应小规模作业砂量的要求，难以满足近年来压裂施工大砂量的要求，且这种方式设备布置灵活性较差、难以实现自动化控制；另一种方式通过集成式气动输送运砂车给储砂装置供砂，由于气动输送设备（包含风机、气输管路等）集成在运砂车上，这就在一定程度上增大了运砂车质量和尺寸，降低了运砂车的道路适应性，提高了对井场道路的要求。Currently, frac sand is shipped to the well site in bags or in bulk. For bagged sand, it needs to be hoisted manually by a crane to the sand inlet of the sand storage device, and then the sand storage device is used to supply sand to the sand mixer truck during the construction process, which has the problems of low operating efficiency and high labor intensity for workers. For bulk sand, one way is to supply sand from the sand tank truck to the sand mixer truck, which often can only meet the requirements of small-scale operation sand volume, and it is difficult to meet the requirements of large sand volume in fracturing construction in recent years, and this method has flexibility in equipment layout It is poor and difficult to realize automatic control; another way is to supply sand to the sand storage device through an integrated pneumatic conveying sand truck. Since the pneumatic conveying equipment (including fans, gas pipelines, etc.) is integrated on the sand truck, this is To a certain extent, the quality and size of the sand truck are increased, the road adaptability of the sand truck is reduced, and the requirements for the well site road are increased.
实用新型内容Utility model content
本实用新型在于优化现有的气动输砂装置，使得压裂砂的输送储运更加方便。The utility model aims to optimize the existing pneumatic sand conveying device, so that the transportation, storage and transportation of fracturing sand are more convenient.
为此，本实用新型提供一种用于压裂施工的气动输砂撬，和运砂车连接，主要由风机、砂斗、下料阀、加速室、撬座组成，其特征在于：上述运砂车为常规罐式运砂车；上述下料阀和上述加速室一体化形成下料阀加速室一体化装置，上述砂斗直接和常规罐式运砂车的尾部出料口对接。For this reason, the utility model provides a pneumatic sand delivery skid for fracturing construction, which is connected with a sand truck, and is mainly composed of a fan, a sand bucket, a feeding valve, an acceleration chamber, and a skid seat. The sand truck is a conventional tank-type sand truck; the above-mentioned discharge valve and the above-mentioned acceleration chamber are integrated to form an integrated device of the discharge valve acceleration chamber, and the above-mentioned sand bucket is directly connected to the tail outlet of the conventional tank-type sand truck.
本实用新型的气动输砂撬上，还可布置有风机驱动电机、控制箱，用于在本地进行风机的驱动及启停操作。风机驱动电机和风机间可以为皮带传动、链传动、齿轮传动、直接驱动等。On the pneumatic sand conveying skid of the utility model, a fan drive motor and a control box can also be arranged, which are used for driving and starting and stopping the fan locally. The fan drive motor and the fan can be belt drive, chain drive, gear drive, direct drive, etc.
本实用新型的气动输砂撬中，下料阀加速室一体化装置可以由电机直接驱动，或通过链传动、齿轮传动、皮带传动等其他传动间接驱动。In the pneumatic sand conveying skid of the utility model, the integrated device of the acceleration chamber of the feeding valve can be directly driven by a motor, or indirectly driven by other transmissions such as chain transmission, gear transmission, and belt transmission.
作为一种优化，气动输砂撬还在撬座下方安装一组滚轮，从而能够更加方便地调整气动输砂撬的位置，使得砂斗对准运砂车出砂口。As an optimization, the pneumatic sand delivery skid is also equipped with a set of rollers under the skid seat, so that the position of the pneumatic sand delivery skid can be adjusted more conveniently, so that the sand bucket is aligned with the sand outlet of the sand truck.
传统气动输砂撬，下料阀与加速室为分体式结构，这样整体体积较大、高度较高，砂斗无法和常规罐式运砂车的尾部出料口对接，需要特制运砂车以增加出料口高度。本专利中，下料阀与加速室设计成下料阀加速室一体化装置，能够在较大程度上减小砂斗进砂口高度，从而使常规运砂车在卸料状态能够很方便地向砂斗供砂。The traditional pneumatic sand delivery skid, the feeding valve and the acceleration chamber are split structures, so the overall volume is large and the height is high, and the sand bucket cannot be docked with the tail outlet of the conventional tank-type sand truck, so a special sand truck is required. Increase the outlet height. In this patent, the unloading valve and the acceleration chamber are designed as an integrated device of the unloading valve acceleration chamber, which can reduce the height of the sand inlet of the sand hopper to a large extent, so that the conventional sand truck can easily Supply sand to the sand bucket.
作为一种优选，该专利的气动输砂撬，其特征在于：上述下料阀加速室一体化装置的出口经软管连接在储砂装置上；储砂装置主要由上罐、下罐套装并经软体囊密封而成。As a preference, the patented pneumatic sand delivery skid is characterized in that: the outlet of the integrated device of the acceleration chamber of the discharge valve is connected to the sand storage device through a hose; the sand storage device is mainly composed of an upper tank and a lower tank. It is sealed by a soft capsule.
储砂装置工作时，上罐上升到高位，上罐、下罐形成最大容积，可储运更多压裂砂。储砂装置运输时上罐下放，上罐、下罐折叠到最小高度以方便运输。When the sand storage device is working, the upper tank rises to a high position, and the upper tank and the lower tank form the largest volume, which can store and transport more fracturing sand. When the sand storage device is transported, the upper tank is lowered, and the upper tank and the lower tank are folded to the minimum height to facilitate transportation.
对于储砂装置的气输管路布置，目前是将主管路（一般为硬管）布置在罐顶。若储砂装置为分仓式结构，则需要在主管路上对应每个料仓配备分路阀，由于高位操作不便，分路阀必须设计为自动阀门，成本较高且需要气源（或液压源）支持。另外，为了将储砂装置的工作容积最大化，储砂装置运输状态高度一般设计达到了运输不超高的极限。如果要使配置了气输管路的储砂装置不超高，则必须牺牲一部分高度，在占地面积不变的情况下必然减小储砂装置的容量。For the gas pipeline layout of the sand storage device, the main pipeline (generally a hard pipe) is currently arranged on the top of the tank. If the sand storage device has a sub-bin structure, it is necessary to equip each silo with a branch valve on the main road. Due to the inconvenience of high-level operation, the branch valve must be designed as an automatic valve, which is costly and requires an air source (or a hydraulic source. )support. In addition, in order to maximize the working volume of the sand storage device, the height of the sand storage device in the transportation state is generally designed to reach the limit of the transportation not to be super high. If the sand storage device configured with gas pipelines is not to be super high, a part of the height must be sacrificed, and the capacity of the sand storage device must be reduced under the condition that the occupied area remains the same.
气动输砂撬与储砂装置之间的管路为软管，气动输砂撬及运砂车与储砂装置之间相对位置关系灵活性较大，这样就可以尽可能充分地利用井场空闲位置，能够在一定程度上缓解目前国内井场征地困难、井场面积小的问题。The pipeline between the pneumatic sand delivery skid and the sand storage device is a hose, and the relative positional relationship between the pneumatic sand delivery skid, the sand delivery vehicle and the sand storage device is relatively flexible, so that the idle space of the well site can be fully utilized as much as possible. The location can, to a certain extent, alleviate the current difficulties in land acquisition and the small size of well sites in China.
运行过程中，只需要工人偶尔调节一下运砂车出砂口阀门，保证压裂砂不至于溢出砂斗即可，工人劳动轻度较小。如果采用自动阀门，根据砂斗的砂量来自动调节阀门开度，则可以不需要人工操作。During operation, workers only need to occasionally adjust the sand outlet valve of the sand truck to ensure that the fracturing sand does not overflow the sand bucket, and the labor is light. If an automatic valve is used to automatically adjust the opening of the valve according to the amount of sand in the sand bucket, no manual operation is required.
由于该分体式气动输砂撬可以和常规罐式运砂车直接连接，且可以实现连续供砂，运砂车满载时能够在半个小时（或更短时间）内将砂卸完。相比现有的两种供砂方式，这种方式作业效率较高。Since the split pneumatic sand delivery skid can be directly connected with the conventional tank-type sand truck, and can realize continuous sand supply, the sand truck can unload the sand within half an hour (or less) when it is fully loaded. Compared with the two existing sand supply methods, this method has higher operating efficiency.
相比常规散装砂直接由砂罐车向混砂车供砂的方式，这种方式能够更好地适应大规模压裂施工大砂量的要求。Compared with the way that the conventional bulk sand is directly supplied from the sand tank truck to the sand mixer truck, this method can better meet the requirements of large sand volume in large-scale fracturing construction.
由于常规运砂车满载时质量较大，再在其基础上增加质量将会降低其道路适应性，特别是提高了井场道路的要求。相比集成式气动输送运砂车给井场储砂装置供砂的方式，本实用新型是独立式供砂方式，不增加运砂车的质量和尺寸，井场布置灵活性较大，可以充分利用空闲的井场面积。Since the mass of the conventional sand truck is large when it is fully loaded, increasing the mass on the basis of it will reduce its road adaptability, especially to improve the requirements of the well site road. Compared with the integrated pneumatic conveying sand truck to supply sand to the sand storage device at the well site, the utility model is an independent sand supply mode, which does not increase the quality and size of the sand truck, and the layout of the well site is more flexible and can fully Utilize vacant well pad area.

为了使本实用新型实现的技术手段、创作特征、达成目的与功效易于明白了解，下面结合具体图示，进一步阐述本实用新型。In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific illustrations.
如图1所示，该实施例的用于压裂施工的气动输砂撬2，在工作时直接和罐式运砂车1出料口对接，经软管5和储砂装置3的气输管路4相连通。As shown in Figure 1, the pneumatic sand delivery skid 2 used for fracturing construction in this embodiment is directly docked with the discharge port of the tank type sand truck 1 during work, and the gas delivery through the hose 5 and the sand storage device 3 Pipeline 4 is connected.
如图2所示，气动输砂撬2由风机驱动电机201、风机202、砂斗203、下料阀加速室一体化装置204、下料阀驱动装置205、控制箱206、撬座207、风机动力传动装置208组成。相对现有技术，该实施将下料阀与加速室采用一体化设计形成下料阀加速室一体化装置204，能够在较大程度上减小砂斗203进砂口高度，从而使常规运砂车1卸料状态能够很方便地向砂斗203供砂。As shown in Figure 2, the pneumatic sand delivery skid 2 is composed of a fan drive motor 201, a fan 202, a sand bucket 203, a discharge valve acceleration chamber integration device 204, a discharge valve drive device 205, a control box 206, a skid seat 207, a fan The power transmission device 208 is composed. Compared with the prior art, this implementation adopts an integrated design of the feeding valve and the acceleration chamber to form the integrated device 204 of the feeding valve acceleration chamber, which can reduce the height of the sand inlet of the sand bucket 203 to a large extent, so that the conventional sand transportation The unloading state of the car 1 can conveniently supply sand to the sand bucket 203 .
砂斗203为压裂砂的输入口，然后压裂砂通过下方的下料阀加速室一体化装置204，下料阀能够保证压裂砂定量进入加速室而不至于阻塞。从砂斗203进入的压裂砂与风机202输出的一定压力的空气在下料阀加速室一体化装置204的加速室高速混合并从出口输出。控制箱206可以进行风机驱动电机201、下料阀驱动装置205的启停和调速控制。The sand bucket 203 is the input port of the fracturing sand, and then the fracturing sand passes through the integrated device 204 of the acceleration chamber of the feeding valve below, and the feeding valve can ensure that the fracturing sand enters the acceleration chamber quantitatively without being blocked. The fracturing sand entering from the sand hopper 203 and the air at a certain pressure output by the fan 202 are mixed at high speed in the acceleration chamber of the integrated device 204 of the discharge valve acceleration chamber and output from the outlet. The control box 206 can control the start-stop and speed regulation of the fan driving motor 201 and the feeding valve driving device 205 .
该实施中，风机驱动电机201和驱动风机202的间为皮带传动。下料阀加速室一体化装置204由电机直接驱动。In this implementation, the fan drive motor 201 and the drive fan 202 are driven by a belt. The integrated device 204 of the feeding valve acceleration chamber is directly driven by a motor.
如图3、图4所示，储砂装置3为上下套罐结构，下罐固定，上罐可上下滑动,两罐之间的密封由固定于上罐顶部及下罐顶部的软体囊来实现。工作时，上罐上升到高位；运输时上罐下放到运输高度。As shown in Figure 3 and Figure 4, the sand storage device 3 is a structure of upper and lower tanks, the lower tank is fixed, the upper tank can slide up and down, and the seal between the two tanks is realized by the soft bag fixed on the top of the upper tank and the top of the lower tank . When working, the upper tank rises to a high position; when transporting, the upper tank lowers to the transport height.
可用于伸缩式储砂装置3的气输管路4，将主管路（为硬管）401布置在储砂装置3的下部、高度在1.2-1.5m的位置。分路阀402设计为自动阀门。从主管路分路阀402分出的各分体仓硬管403从储砂装置3下罐锥部进入各分体仓，分体仓硬管403进入分体仓内露头后通过仓内软管404连接到顶部出料口硬管接头出料口405，该出料口固定在储砂装置3顶部。出料口方向朝上，混合物料喷出后打到挡料板406上后反弹回料仓。经过反弹后的混合物料动能大幅度减小，对分仓体内壁软体囊及仓内软管404的冲击大幅度降低，从而大幅度减小对软体囊及仓内软管404的破坏程度。另外，这种管路4罐顶高度增加很小，对储砂装置3容量的影响也很小。各分体仓内绝大部分管路为软管，能够较好地适应储砂装置3上罐体伸缩的要求。It can be used for the gas transmission pipeline 4 of the telescopic sand storage device 3, and the main pipeline (hard pipe) 401 is arranged at the lower part of the sand storage device 3 at a height of 1.2-1.5m. The bypass valve 402 is designed as an automatic valve. The hard pipes 403 of the split bins separated from the branch valve 402 of the main pipeline enter the split bins from the cone of the lower tank of the sand storage device 3, and the hard pipes 403 of the split bins enter the outcrops of the split bins and pass through the hoses in the bins 404 is connected to the discharge port 405 of the hard pipe joint at the top discharge port, and the discharge port is fixed on the top of the sand storage device 3 . The direction of the discharge port is upward, and the mixed material hits the baffle plate 406 after being sprayed out and rebounds back to the feed bin. The kinetic energy of the rebounded mixed material is greatly reduced, and the impact on the inner wall soft bag and the inner hose 404 of the compartment is greatly reduced, thereby greatly reducing the degree of damage to the soft bag and the inner hose 404 . In addition, the increase in the height of the tank top of the pipeline 4 is very small, and the impact on the capacity of the sand storage device 3 is also very small. Most of the pipelines in each split bin are flexible pipes, which can better meet the requirements of the expansion and contraction of the tank body on the sand storage device 3 .
运砂车1将压裂砂运输到压裂井场并将出砂口对准气动输砂撬2的砂斗203，连接气动输砂撬2与储砂装置3之间的管路，由于气动输砂撬2与储砂装置3之间的管路为软管，所以气动输砂撬2及运砂车1与储砂装置3之间相对位置关系灵活性较大，这样就可以尽可能充分地利用井场空闲位置，能够在一定程度上缓解目前国内井场征地困难、井场面积小的问题。The sand truck 1 transports the fracturing sand to the fracturing well site and aligns the sand outlet with the sand bucket 203 of the pneumatic sand delivery skid 2, and connects the pipeline between the pneumatic sand delivery skid 2 and the sand storage device 3. The pipeline between the sand delivery skid 2 and the sand storage device 3 is a flexible hose, so the relative positional relationship between the pneumatic sand delivery skid 2 and the sand transport vehicle 1 and the sand storage device 3 is relatively flexible, so that it can be as fully as possible. The use of free space in the well site can alleviate to a certain extent the problems of difficulty in land acquisition and small well site area in China.
该系统运行过程中，只需要工人偶尔调节一下运砂车1出砂口阀门，保证压裂砂不至于溢出砂斗203即可，工人劳动轻度较小。如果采用自动阀门，根据砂斗203的砂量来自动调节阀门开度，则可以不需要人工操作。During the operation of the system, workers only need to occasionally adjust the sand outlet valve of the sand truck 1 to ensure that the fracturing sand does not overflow the sand bucket 203, and the labor of the workers is relatively small. If an automatic valve is used to automatically adjust the opening of the valve according to the amount of sand in the sand bucket 203, manual operation is not required.
由于气动输砂撬可以实现连续供砂，运砂车1满载时能够在半个小时（或更短时间）内将砂卸完。相比上文提到的两种供砂方式，这种方式作业效率较高。Since the pneumatic sand delivery skid can realize continuous sand supply, the sand truck 1 can unload the sand within half an hour (or less) when it is fully loaded. Compared with the two sand supply methods mentioned above, this method has higher operating efficiency.
这种方式是在压裂施工前就把压裂砂用砂罐车气输到井场本地储砂装置。储砂装置3准备好，砂容量可大可小。相比常规散装砂直接由砂罐车1向混砂车供砂的方式，这种方式能够更好地适应大规模压裂施工大砂量的要求。In this way, the fracturing sand is transported to the local sand storage device at the well site with sand tanker gas before the fracturing operation. The sand storage device 3 is ready, and the sand capacity can be large or small. Compared with the way of conventional bulk sand directly supplied by the sand tank truck 1 to the sand mixer truck, this method can better meet the requirements of large sand volume in large-scale fracturing construction.
由于常规运砂车满载时质量较大，再在其基础上增加质量将会降低其道路适应性，特别是提高了井场道路的要求。增加其长度，同样会高了井场道路的要求。相比集成式气动输送运砂车给井场储砂装置供砂的方式，这种独立式供砂方式不增加运砂车的质量和尺寸，且气动输砂撬2尺寸较小，井场布置灵活性较大，可以充分利用空闲的井场面积。Since the mass of the conventional sand truck is large when it is fully loaded, increasing the mass on the basis of it will reduce its road adaptability, especially to improve the requirements of the well site road. Increasing its length will also increase the requirements of the well site road. Compared with the integrated pneumatic conveying sand truck to supply sand to the sand storage device at the well site, this independent sand supply method does not increase the quality and size of the sand truck, and the size of the pneumatic sand transport skid 2 is small, and the layout of the well site It has great flexibility and can make full use of the free well site area.
以上是本实用新型的实施方式之一，对于本领域内的一般技术人员，不花费创造性的劳动，在上述实施例的基础上可以做多种变化，同样能够实现本实用新型的目的。但是，这种变化显然应该在本实用新型的权利要求书的保护范围内。The above is one of the embodiments of the present utility model. For those skilled in the art, various changes can be made on the basis of the above-mentioned embodiments without creative labor, and the purpose of the present utility model can also be achieved. However, such changes should obviously be within the protection scope of the claims of the present utility model.
