技术领域Technical Field
本发明涉及海油开采测试仪器技术领域，具体涉及一种模块式流体循环测试系统。The invention relates to the technical field of offshore oil production testing instruments, and in particular to a modular fluid circulation testing system.
背景技术Background technique
旋转导向钻井系统（RSS）及随钻测井系统（LWD）以钻井液作为发电及信号传输介质，在该类技术研究和仪器研制的过程中，需要对钻井液的流场特性进行深入研究，而去作业现场开展此类研究存在着诸多困难，难以实现。故而，现行成熟的做法是在实验室建设一套模拟钻井液现场循环工况的流体循环测试系统，用以模拟作业现场的井深、排量和压力环境。The rotary steerable drilling system (RSS) and logging while drilling system (LWD) use drilling fluid as the medium for power generation and signal transmission. In the process of such technical research and instrument development, it is necessary to conduct in-depth research on the flow field characteristics of the drilling fluid. However, there are many difficulties in conducting such research at the operation site, and it is difficult to achieve. Therefore, the current mature practice is to build a fluid circulation test system in the laboratory to simulate the on-site circulation conditions of the drilling fluid, so as to simulate the well depth, displacement and pressure environment at the operation site.
为了模拟现场作业井深，现有的流体循环测试系统多采用直管连接的方式布设在地面上，该方式占地面积大，施工难度和成本均较高，难以大规模推广使用，且一旦建成，后期扩容难度极大，无法模拟更深的井眼环境。另外，现有的流体循环测试系统无法实现循环长度一键式切换，需要人工手动去逐一调整相关阀门来实现不同循环长度的切换。此外，现有的流体循环测试系统也不具备远程控制功能。In order to simulate the well depth of on-site operations, the existing fluid circulation test system is mostly laid on the ground using straight pipe connections. This method occupies a large area, has high construction difficulty and cost, and is difficult to promote on a large scale. Once built, it is extremely difficult to expand capacity later, and it is impossible to simulate deeper wellbore environments. In addition, the existing fluid circulation test system cannot achieve one-click switching of the circulation length, and requires manual adjustment of the relevant valves one by one to achieve switching of different circulation lengths. In addition, the existing fluid circulation test system does not have remote control function.

具体实施方式Detailed ways
为了更好的了解本发明的目的、结构及功能，下面结合附图，对本发明做进一步详细的描述。In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.
图1示出了根据本发明实施例的模块式流体循环测试系统100的结构。如图1所示，该模块式流体循环测试系统100可包括：循环池1、泵送装置2、指令下传装置3、循环管道4，待测试仪器5，以及分别与指令下传装置3和泵送装置2电连接的测控系统6，测控系统6控制泵送装置2将循环池1内的流体泵送至指令下传装置3时控制指令下传装置3将流体分流，以使流体的一部分依次经循环管道4和待测试仪器5回流至循环池1，而使流体的另一部分直接流至循环池1。其中，如图2所示，循环管道4包括基本管线41和与基本管线41串联的模块式管线42，如图3所示，模块式管线42可包括至少一个连续油管模块421，连续油管模块421包括具有特定长度且盘绕布置的连续油管。FIG1 shows the structure of a modular fluid circulation test system 100 according to an embodiment of the present invention. As shown in FIG1 , the modular fluid circulation test system 100 may include: a circulation pool 1, a pumping device 2, an instruction transmission device 3, a circulation pipeline 4, an instrument to be tested 5, and a measurement and control system 6 electrically connected to the instruction transmission device 3 and the pumping device 2, respectively. The measurement and control system 6 controls the pumping device 2 to pump the fluid in the circulation pool 1 to the instruction transmission device 3, and controls the instruction transmission device 3 to divert the fluid, so that a part of the fluid flows back to the circulation pool 1 through the circulation pipeline 4 and the instrument to be tested 5 in sequence, and another part of the fluid flows directly to the circulation pool 1. As shown in FIG2 , the circulation pipeline 4 includes a basic pipeline 41 and a modular pipeline 42 connected in series with the basic pipeline 41. As shown in FIG3 , the modular pipeline 42 may include at least one continuous tubing module 421, and the continuous tubing module 421 includes a continuous tubing with a specific length and a coiled arrangement.
本发明实施例的模块式流体循环测试系统100在工作时，如图1所示，在测控系统6的控制下，指令下传装置3可以利用第一分支管线81和第二分支管线82进行流体的分流，通过使液体分流来使经循环管道4进入待测试仪器5内的流体的流量和压力产生变化，从而测试待测试仪器5工作性能。在本发明实施例的模块式流体循环测试系统100中，通过在基本管线41的基础上增加了与其串联的模块式管线42，该模块式管线42的设置不仅可用于实现对基本管线41的扩容作用，使得循环管道4具有更多可选择的循环长度，从而能够在不同的循环长度下测量待测试仪器5的工作性能。同时模块式管线42的连续油管模块421内部连续油管的盘绕布置方式完全不同于现有技术中采用直管连接并平铺于地面的布置方式，可有效地减小模块式管线42的占地面积，从而使得模块式流体循环测试系统100的循环管道在扩容的基础上能够最小的占用布线空间。此外，通过将模块式管线42的连续油管模块421进行模块化设计，即使每个连续油管模块421均包括具有特定长度且盘绕布置的连续油管，该特定长度例如可以是图2所示的1500米，一方面可使循环长度的计算和选择更为简单便捷，另一方面还可便于连续油管模块421的制造和连接。When the modular fluid circulation test system 100 of the embodiment of the present invention is working, as shown in FIG1 , under the control of the measurement and control system 6, the instruction transmission device 3 can use the first branch pipeline 81 and the second branch pipeline 82 to divert the fluid, and by diverting the liquid, the flow rate and pressure of the fluid entering the instrument to be tested 5 through the circulation pipeline 4 are changed, thereby testing the working performance of the instrument to be tested 5. In the modular fluid circulation test system 100 of the embodiment of the present invention, by adding a modular pipeline 42 connected in series with the basic pipeline 41, the setting of the modular pipeline 42 can not only be used to achieve the expansion effect of the basic pipeline 41, but also make the circulation pipeline 4 have more selectable circulation lengths, so that the working performance of the instrument to be tested 5 can be measured at different circulation lengths. At the same time, the coiled arrangement of the continuous tubing inside the continuous tubing module 421 of the modular pipeline 42 is completely different from the arrangement of the prior art that uses straight pipes to connect and lay flat on the ground, which can effectively reduce the footprint of the modular pipeline 42, so that the circulation pipeline of the modular fluid circulation test system 100 can occupy the minimum wiring space on the basis of expansion. In addition, by modularizing the coiled tubing modules 421 of the modular pipeline 42, even if each coiled tubing module 421 includes a coiled tubing having a specific length, the specific length may be, for example, 1500 meters as shown in FIG. 2 . This can make the calculation and selection of the circulation length simpler and more convenient, and can also facilitate the manufacture and connection of the coiled tubing modules 421.
本发明实施例的模块式流体循环测试系统100在扩容后占地面积更小，施工难度和成本均较低，在建成后，后期扩容更为简单方便，可以模拟更深的井眼环境，可大规模推广使用。The modular fluid circulation test system 100 of the embodiment of the present invention occupies a smaller area after expansion, and has lower construction difficulty and cost. After completion, subsequent expansion is simpler and more convenient, and it can simulate deeper wellbore environments and can be promoted for large-scale use.
在如图3所示的实施例中，连续油管模块421还可包括盘绕架422，连续油管可盘绕在盘绕架422上。盘绕架422一方面可实现对连续油管的盘绕支撑，另一方面也可起到对连续油管的保护作用。In the embodiment shown in Fig. 3, the coiled tubing module 421 may further include a coiling frame 422, and the coiled tubing may be coiled on the coiling frame 422. The coiling frame 422 may provide coiling support for the coiled tubing on one hand, and may also protect the coiled tubing on the other hand.
优选地，如图3所示，模块式管线42可包括多个串联的连续油管模块421，相邻连续油管模块421的连续油管首尾相连。通过设定模块式管线42中连续油管模块421的个数来具体选择所需扩容的循环长度。Preferably, as shown in Fig. 3, the modular pipeline 42 may include a plurality of serially connected coiled tubing modules 421, and the coiled tubings of adjacent coiled tubing modules 421 are connected end to end. The cycle length required for expansion is specifically selected by setting the number of coiled tubing modules 421 in the modular pipeline 42.
根据本发明，通过合理布置各连续油管模块421的位置，可进一步减小模块式管线42的占地面积。优选地，在如图3所示的实施例中，可将各连续油管模块421横向排布，并间隔固定在支撑板423上。在另一个优选的实施例中，可将各连续油管模块421纵向排布，各连续油管模块421可通过支架在纵向上间隔固定，以进一步降低模块式管线42的占地面积。According to the present invention, the footprint of the modular pipeline 42 can be further reduced by properly arranging the positions of the coiled tubing modules 421. Preferably, in the embodiment shown in FIG. 3 , the coiled tubing modules 421 can be arranged transversely and fixed at intervals on the support plate 423. In another preferred embodiment, the coiled tubing modules 421 can be arranged longitudinally, and the coiled tubing modules 421 can be fixed longitudinally at intervals by brackets, so as to further reduce the footprint of the modular pipeline 42.
根据本发明，在如图2所示的实施例中，基本管线41可包括多个基本循环长度44，模块式管线42可包括至少一个特定循环长度45，各基本循环长度44和/或各特定循环长度45可通过其上相应的电动阀门组合的启闭进行叠加，以实现所需的循环长度的选取，各电动阀门分别与测控系统6电连接，以控制各电动阀门的启闭。在该实施例中，多种循环长度可通过电动阀门自由切换，可通过远程控制和人工控制两种模式对电动阀门进行控制，通过对电动阀门的状态进行实时监控，比人工控制模式更加安全高效。According to the present invention, in the embodiment shown in FIG. 2 , the basic pipeline 41 may include multiple basic cycle lengths 44, and the modular pipeline 42 may include at least one specific cycle length 45. Each basic cycle length 44 and/or each specific cycle length 45 may be superimposed by the opening and closing of the corresponding electric valve combination thereon to achieve the selection of the required cycle length, and each electric valve is electrically connected to the measurement and control system 6 to control the opening and closing of each electric valve. In this embodiment, multiple cycle lengths can be freely switched through the electric valve, and the electric valve can be controlled by remote control and manual control modes. By real-time monitoring of the state of the electric valve, it is safer and more efficient than the manual control mode.
在如图2所示的实施例中，循环管道4包括主管线43，主管线43一端与指令下传装置3相连，另一端与待测试仪器5相连通，各基本循环长度44和各特定循环长度45所对应的管线的进口和出口均可选择地与主管线43相连通。In the embodiment shown in Figure 2, the circulation pipeline 4 includes a main line 43, one end of the main line 43 is connected to the instruction transmission device 3, and the other end is connected to the instrument to be tested 5. The inlet and outlet of the pipeline corresponding to each basic cycle length 44 and each specific cycle length 45 can be selectively connected to the main line 43.
如图2所示，以基本管线41的最长长度为3122米，模块式管线42的最长长度为3000米，其中，模块式管线42包含两个连续油管模块421，每个连续油管模块421的连续油管的长度均为1500米为例，其最大循环长度为6122米，为当前世界最长循环长度，共可模拟14种循环长度，为目前之最。如下表1示出了不同循环长度下各电动阀门（共16个电动阀门F1~F16）的控制逻辑，即各基本循环长度44和/或各特定循环长度45在选取时所对应的管线上的电动阀门的启闭状态。As shown in FIG2 , taking the maximum length of the basic pipeline 41 as 3122 meters and the maximum length of the modular pipeline 42 as 3000 meters, where the modular pipeline 42 includes two coiled tubing modules 421, and the length of the coiled tubing of each coiled tubing module 421 is 1500 meters as an example, its maximum cycle length is 6122 meters, which is the longest cycle length in the world at present, and a total of 14 cycle lengths can be simulated, which is the highest at present. The following Table 1 shows the control logic of each electric valve (a total of 16 electric valves F1~F16) under different cycle lengths, that is, the opening and closing states of the electric valves on the pipeline corresponding to each basic cycle length 44 and/or each specific cycle length 45 when selected.
其中，所需的循环长度可以是零米，也可以是至少两个基本循环长度44之间的叠加，也可以是至少一个基本循环长度44与至少一个特定循环长度45的叠加，还可以是特定循环长度45的倍数N（N≥1），详见下表1。The required cycle length may be zero meter, or the superposition of at least two basic cycle lengths 44, or the superposition of at least one basic cycle length 44 and at least one specific cycle length 45, or a multiple N (N≥1) of the specific cycle length 45, as shown in Table 1 below.
在图2所示的实施例中，模块式管线42的最长长度3000米相比于同样长度的连续油管来说，占地面积仅为直管的18%左右，极大地降低了模块式管线42的占地面积。In the embodiment shown in FIG. 2 , the maximum length of the modular pipeline 42 is 3,000 meters. Compared with a coiled tubing of the same length, the footprint of the modular pipeline 42 is only about 18% of that of a straight pipe, which greatly reduces the footprint of the modular pipeline 42 .
根据本发明，如图1和图4所示的优选的实施例中，模块式流体循环测试系统100还可包括传感器装置7，传感器装置7可包括位于泵送装置2与指令下传装置3之间的第一传感器组71，位于指令下传装置3与循环池1之间的第二传感器组72，位于待测试仪器5与循环池1之间的第三传感器组73，以及位于循环管道4与待测试仪器5之间的第四传感器组74，第一传感器组71、第二传感器组72、第三传感器组73以及第四传感器组74分别与测控系统6电连接。传感器装置7用来实现流体压力和流量信号的采集并将采集的信号传递至测控系统6。According to the present invention, in the preferred embodiment shown in FIG. 1 and FIG. 4 , the modular fluid circulation test system 100 may further include a sensor device 7, which may include a first sensor group 71 located between the pumping device 2 and the instruction transmission device 3, a second sensor group 72 located between the instruction transmission device 3 and the circulation pool 1, a third sensor group 73 located between the instrument to be tested 5 and the circulation pool 1, and a fourth sensor group 74 located between the circulation pipeline 4 and the instrument to be tested 5.

The sensor device 7 is used to collect fluid pressure and flow signals and transmit the collected signals to the measurement and control system 6.
在该实施例中，通过设置第一传感器组71和第二传感器组72，可监测第一分支管线81上的流体压力和流量的变化，以使测控系统能够根据该变化控制指令下传装置3利用第一分支管线81和第二分支管线82进行流体的分流；通过设置第三传感器组73以及第四传感器组74，可监测待测试仪器5的进口处和出口处的流体压力和流量的变化，以用于测试待测试仪器的工作性能。In this embodiment, by setting the first sensor group 71 and the second sensor group 72, the changes in the fluid pressure and flow on the first branch pipeline 81 can be monitored, so that the measurement and control system can control the instruction transmitting device 3 to use the first branch pipeline 81 and the second branch pipeline 82 to divert the fluid according to the changes; by setting the third sensor group 73 and the fourth sensor group 74, the changes in the fluid pressure and flow at the inlet and outlet of the instrument to be tested 5 can be monitored, so as to test the working performance of the instrument to be tested.

根据本发明，在如图1所示的实施例中，泵送装置2可包括串联的灌注泵22和泥浆泵21，泥浆泵21与指令下传装置3相连，灌注泵22与循环池1相连；或者，泵送装置2可包括串联的灌注泵22和柴驱泵（图中未示出），柴驱泵与指令下传装置3相连，灌注泵22与循环池1相连。也就是说，本发明实施例的模块式流体循环测试系统100可采用泥浆泵21或者柴驱泵作为循环动力，具体采用哪种方式，可根据实际情况而定。泥浆泵一般通过电机驱动，对电力功率要求较大，对供电能力充裕的单位，采用此方式较为合适；柴驱泵通过柴油发电机驱动，不依赖于外部电力，且可自由吊装运输，具备很大的便利性和灵活性。泥浆泵21与灌注泵22的配合使用，以及柴驱泵与灌注泵22的配合使用，可提高泥浆泵的排量和冲速，避免产生气塞现象。According to the present invention, in the embodiment shown in FIG. 1 , the pumping device 2 may include a series-connected perfusion pump 22 and a mud pump 21, the mud pump 21 is connected to the instruction transmission device 3, and the perfusion pump 22 is connected to the circulation pool 1; or, the pumping device 2 may include a series-connected perfusion pump 22 and a diesel-driven pump (not shown in the figure), the diesel-driven pump is connected to the instruction transmission device 3, and the perfusion pump 22 is connected to the circulation pool 1. That is, the modular fluid circulation test system 100 of the embodiment of the present invention can use a mud pump 21 or a diesel-driven pump as the circulation power, and which method is used specifically can be determined according to actual conditions. The mud pump is generally driven by a motor, which has a large requirement for electric power, and is more suitable for units with sufficient power supply capacity; the diesel-driven pump is driven by a diesel generator, does not rely on external power, and can be freely hoisted and transported, and has great convenience and flexibility. The use of the mud pump 21 and the perfusion pump 22, as well as the use of the diesel-driven pump and the perfusion pump 22, can increase the displacement and stroke speed of the mud pump and avoid the occurrence of air plugging.
