[0002] With the continuous consumption of oil and gas resources, the contradiction between supply and demand of oil and gas has become increasingly prominent. China is rich in shale oil resources, and the development of shale oil can greatly alleviate the shortage of oil and gas resources in China. During the development of shale oil, well testing of shale oil wells is a very important stage.

[0054] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the accompanying drawings.

[0055] Before explaining the embodiments of the present application in detail, the application scenarios in the embodiments of the present application will be described first.

[0056] The well testing device provided by the embodiments of the present application can be applied to the early development process of any shale oil well to obtain well testing data in the early stage of oil production in the shale oil well. The early stage of oil production refers to the stage during the shut-in period of the shale oil and after the shut-in well is opened. The well testing data in the early stage of oil production in the shale oil well refers to the change of pressure data during the shut-in period of the shale oil well and the change of pressure data after the shut-in well is opened.

[0057] Figure 1 It is a schematic side view structural diagram of a well testing device provided by an embodiment of the present application. Refer to Figure 1 , the well testing device includes: a front baffle 1, a main body 2, and a back plate 3. One end of the main body 2 is connected to the front baffle 1, and the other end of the main body 2 is connected to the back plate 3. An open cavity is formed between the front baffle 1, the main body 2, and the back plate 3 for placing a pressure gauge. There are gaps arranged on the front baffle 1, and there are telescopic support arms on the back plate 3 for fixing the back plate inside the pipe wall of the Christmas tree, and the Christmas tree is the Christmas tree arranged on the well to be detected.

[0058] In the embodiments of the present application, the well testing device is placed inside the pipe wall of the Christmas tree to conduct well testing on the oil well. The Christmas tree is the Christmas tree arranged on the well to be detected, and the well testing device stores a pressure gauge. Therefore, the well testing device inside the pipe wall of the Christmas tree can conduct well testing on the oil well, thus solving the problem that the well testing device cannot be placed inside the oil well and resulting in the inability to conduct well testing, that is, the well testing device can conduct well testing on the oil well without being placed inside the well of the oil well, and further, the pressure data of the oil well can be obtained, providing information on the pressure data for the subsequent construction of the oil well.

[0059] Since the distance between the front baffle 1 and the oil inlet is less than the distance between the back plate 3 and the oil inlet, and in order to enable the pressure gauge placed in the cavity to measure the pressure of the liquid inside the oil well. Therefore, gaps are arranged on the front baffle 1 closest to the oil inlet, so that the liquid inside the oil well flows into the cavity, and the pressure measured by the pressure gauge at this time is the pressure of the liquid inside the oil well. Figure 2 It is a schematic structural diagram of a front baffle provided by an embodiment of the present application. Refer toFigure 2 The front baffle 1 is a circular ring with slits 12, and multiple slits 12 are evenly distributed inside the circular ring.

[0060] In order to enable the pressure gauge to stably measure the pressure data of the liquid in the oil well, it is necessary to fix the well testing device placed inside the pipe wall of the Christmas tree. Therefore, there are retractable support arms on the back plate 3 of the well testing device, and the support arms can fix the back plate 3 inside the pipe wall of the Christmas tree, so as to fix the well testing device inside the pipe wall of the Christmas tree.

[0061] Among them, between the main body 2 and the front baffle 1, and between the main body 2 and the back plate 3, connection can be achieved by means of riveting. Of course, connection can also be achieved by other means, and the embodiments of the present application do not make specific limitations in this regard.

[0062] In addition, in order to make the well testing device fit more closely to the circular pipe wall of the Christmas tree, in a possible implementation manner, see Figure 1 and Figure 2 , the main body 2 includes multiple connecting pipes. The front baffle 1 and the back plate 3 are both circular. One end of each connecting pipe among the multiple connecting pipes is evenly fixed at the edge of the front baffle 1. As Figure 2 shown, the connecting pipe of the main body 2 and the front baffle 1 are connected through the small circles 13 at the edge of the circular ring. The other end of each connecting pipe among the multiple connecting pipes is evenly fixed at the edge of the back plate 3, and the multiple connecting pipes form the wall of a U-shaped groove. Of course, the front baffle 1, the main body 2, and the back plate 3 can also have other structures, and the embodiments of the present application do not make specific limitations in this regard.

[0063] It should be noted that in order to ensure the long-term measurement of the liquid pressure in the oil well, multiple pressure gauges can be placed in the well testing device to prevent incomplete recording of the liquid pressure data in the oil well due to insufficient battery power of the pressure gauge.

[0064] Figure 3 is a schematic side view structure diagram of a Christmas tree provided by an embodiment of the present application. The Christmas tree 300 is a control device for oil extraction, and the Christmas tree 300 is usually located above the wellhead of an oil and gas well. As Figure 3 shown, the structure of the Christmas tree 300 is generally two horizontal and one vertical. The two horizontal parts are the flanks 310 of the Christmas tree 300. The flank on the left side of the Christmas tree 300 can be called the left flank, and the flank on the right side of the Christmas tree 300 can be called the right flank. The one vertical part is the main body 320 of the Christmas tree 300. The flanks and the main body of the Christmas tree 300 are all called oil pipes, and multiple gates 330 are arranged on the oil pipes. When the gate of a certain oil pipe of the Christmas tree 300 is opened, the oil in the oil and gas well can flow into this oil pipe. In addition, the Christmas tree 300 can also include multiple flank structures, and the embodiments of the present application do not make specific limitations in this regard.

[0065] Next, the structure of the back plate will be described in detail.

[0066] Figure 4 This is a schematic structural diagram of a backplane provided by an embodiment of the present application. Refer to Figure 4 , on the backplane 3, a lock core 31, a lock body 32, and two limit pins 33 are arranged. The lock body 32 includes two support arms 321, two springs 322, and a lock hole 323. The two springs 322 are respectively sleeved outside the two support arms 321, and the two support arms 321 are respectively connected to the lock core 31.

[0067] Figure 5 This is a schematic structural diagram of a lock hole provided by an embodiment of the present application. Refer to Figure 5 , the lock hole 323 is a hollow ring, and the limit pin 33 is inside the lock hole 323. Place the lock core 31 inside the lock hole 323, and the upper and lower edges of the lock core 31 coincide with one of the two limit pins 33, and the left and right edges of the lock core 31 coincide with the other limit pin 33.

[0068] The well testing device further includes a key 6. Figure 6 This is a schematic structural diagram of a key provided by an embodiment of the present application. Refer to Figure 6 , the key 4 has a T-shaped structure. The key 4 includes a handle 41, a long tube 42, and two rectangular locking blocks. Among them, the construction personnel can operate the key 4 through the handle 41 to lock the rectangular locking block of the key 4 to the lock core and rotate it.

[0069] Figure 7 This is a schematic structural diagram of a lock core provided by an embodiment of the present application. Refer to Figure 7 , the distance between the left and right edges of the lock core 31 is not equal to the distance between the upper and lower edges of the lock core 31. When the key 4 rotates the lock core 31 to the position where one of the limit pins is located in the lock hole 323, the support arm 321 is connected to the pipe wall of the Christmas tree. When the key rotates the lock core 31 to the position where the other limit pin is located in the lock hole 323, the support arm 321 is not connected to the pipe wall of the Christmas tree.

[0070] Among them, between the backplane 3 and the lock core 31, and between the backplane 3 and the lock body 32, the connection is achieved by means of screws. Of course, the connection can also be achieved by other means, and the embodiments of the present application do not make specific limitations in this regard. The connection between the limit pin 33 and the backplane 3 is achieved by means of threads, and the connection can also be achieved by other means, and the embodiments of the present application do not make specific limitations in this regard. The connection between the support arm 321 and the lock body 32 is achieved by fixing nuts at the opening of the lock body 32. The fixing nut has an opening in the middle, and the support arm 321 can be connected to the pipe wall through the opening of the fixing nut.

[0071] It should be noted that the lock body 32 is fixed in the fixing holes 325 on the back plate 3 through screws. The number of fixing holes 325 on the back plate 3 can be three, and the embodiments of the present application do not make specific limitations on this.

[0072] In a possible implementation manner, Figure 7 is a schematic structural diagram of a lock core provided by an embodiment of the present application. Refer to Figure 7 , the distance between the left and right edges of the lock core 31 is greater than the distance between the upper and lower edges of the lock core 31. At this time, if the upper and lower edges of the lock core 31 contact the two support arms 321 in the lock body 32, the support arms 321 are just located in the openings on both sides of the lock body 32. Refer to Figure 4 . If the left and right edges of the lock core 31 contact the two support arms 321 in the lock body 32, since the distance between the left and right edges of the lock core 31 is greater than the distance between the upper and lower edges of the lock core 31, the lock core 31 causes the support arms 321 to penetrate through the openings on both sides of the lock body 32, so that the support arms 321 are connected to the pipe wall. Refer to Figure 8 .

[0073] In a possible implementation manner, the key 4 rotates the lock core 31 clockwise in the lock hole 323 until the lock core 31 coincides with one of the two limit pins 33. Or the key 4 rotates the lock core 31 counterclockwise in the lock hole 323 until the lock core 31 coincides with one of the two limit pins 33. It should be noted that when rotating the lock core 31 with the key 4, whether rotating clockwise or counterclockwise, the rotation angle is 90 degrees.

[0074] The well testing device further includes an operating arm 5, Figure 9 is a schematic structural diagram of an operating arm provided by an embodiment of the present application. The operating arm 5 is in a T-shaped structure. The operating arm 5 includes a handle 51 and a long tube 52, and the construction personnel can control the operating arm 5 through the handle 51. An operating hole 324 is also arranged on the back plate 3. Refer to Figure 4 , and the operating arm 5 is used to insert into the operating hole 324 to send the well testing device into the pipeline of the Christmas tree.

[0075] In a possible implementation manner, the operating arm 5 and the operating hole 324 can be connected by means of threaded connection. Of course, they can also be connected by other means, and the embodiments of the present application do not make specific limitations on this.

[0076] In summary, in the embodiment of the present application, a well testing device is placed inside the pipe wall of the Christmas tree to perform well testing on the oil well. The Christmas tree is the Christmas tree arranged on the well to be detected, and a pressure gauge is stored in the well testing device. Therefore, the well testing device inside the pipe wall of the Christmas tree can perform well testing on the oil well, thereby solving the problem that the well testing device cannot be put into the oil well, that is, the well testing device can perform well testing on the oil well without being put into the well of the oil well, and further, the pressure data of the oil well can be obtained, providing information on the pressure data for the later oil well construction.

[0077] Figure 10 FIG. is a flowchart of a well testing method provided by an embodiment of the present application. This method is applied to a terminal. The embodiment of the present application does not limit the execution subject of this method. The following embodiments will be described by taking the terminal as the execution subject as an example. Refer to Figure 10 and the well testing method may include the following steps.

[0078] Step 1001: The terminal controls the first gate on the Christmas tree to open. The Christmas tree also includes a second gate. The distance between the second gate and the oil inlet of the Christmas tree is less than the distance between the first gate and the oil inlet of the Christmas tree. The Christmas tree is the Christmas tree arranged on the well to be detected.

[0079] Refer to Figure 3 and in a possible implementation manner, two gates on the left wing of the Christmas tree are respectively selected as the first gate and the second gate, and the distance between the second gate and the oil inlet of the Christmas tree is less than the distance between the first gate and the oil inlet of the Christmas tree.

[0080] In order to place the well testing device inside the pipe wall between the first gate and the second gate, the first gate needs to be opened.

[0081] Step 1002: The terminal places the well testing device through the first gate inside the pipe wall between the first gate and the second gate of the Christmas tree. A pressure gauge is placed inside the well testing device.

[0082] In a possible implementation manner, the terminal places the well testing device inside the pipe wall between the first gate and the second gate of the Christmas tree through the operating arm.

[0083] Optionally, the well testing device can also be placed between the first gate and the end of the oil pipe where the first gate is located. The embodiment of the present application does not make specific limitations on this.

[0084] Step 1003: The terminal controls the first gate to close and the second gate to open so that the pressure gauge collects the pressure inside the well to be detected.

[0085] In order to measure the liquid pressure in the oil well, the terminal needs to control the second gate to open so that the liquid in the oil well can flow into the oil pipe where the well testing device is located, so that the pressure collected by the pressure gauge is the pressure in the well to be detected. And in order to measure the liquid pressure in the oil well during the shut-in period, the terminal needs to control the first gate to close to prevent the liquid in the oil well from flowing out of the oil pipe, so that the pressure collected by the pressure gauge is the pressure in the well to be shut in for testing.

[0086] Optionally, if the well testing device is placed between the first gate and the end of the oil pipe where the first gate is located, the terminal needs to control the first gate and the second gate to open simultaneously so that the liquid in the oil well can flow into the oil pipe where the well testing device is located, so that the pressure collected by the pressure gauge in the well testing device is the pressure in the well to be detected.

[0087] It should be noted that after the well testing device is placed in the production tree oil pipe, the terminal seals the end of the oil pipe to prevent the liquid in the oil well from flowing out of the end of the oil pipe. In a possible implementation, the terminal installs a pressure gauge at the end of the production tree oil pipe to seal the end of the oil pipe.

[0088] In addition, when there are two pressure gauges in the well testing device, the working times of the two pressure gauges can be set in advance so that the two pressure gauges take turns to complete the pressure monitoring. For example, if the well testing device needs to measure the change of the pressure data in the oil well for 10 days, set the working time of one pressure gauge to the first 5 days and the working time of the other pressure gauge to the last 5 days. Thus, it is possible to prevent the situation where the battery runs out due to the pressure gauge working for too long.

[0089] When it is determined that the shut-in duration has reached, control the first gate to open, control the second gate to close, and control the well testing device to be removed from the production tree. The terminal controls the well testing device to be removed between the first gate and the second gate of the production tree through the operating arm, obtains the pressure collected by the pressure gauge, and takes the pressure as the pressure in the well to be detected during the shut-in duration.

[0090] In a possible implementation, the shut-in duration can be determined by experience.

[0091] After the shut-in duration has reached, in order to remove the well testing device from the production tree, it is necessary to control the first gate to open. In addition, in order to prevent the liquid in the oil well from flowing out, it is necessary to control the second gate to close.

[0092] The specific process of removing the well testing device from the production tree is as follows: In a possible implementation, the terminal controls the well testing device to be removed between the first gate and the second gate of the production tree through the operating arm.

[0093] In addition, when the first gate is opened and the second gate is not immediately controlled to close, at this time, the pressure gauge measures the pressure data after the shut-in well is opened. After the shut-in well is opened, the pressure in the oil well will rapidly decrease. After the data on the pressure gauge stabilizes, the second gate is controlled to close.

[0094] In another possible implementation, when the first gate is opened and the second gate is not closed, other information such as the liquid production volume in the oil well can also be measured. The embodiments of the present application do not make specific limitations on this.

[0095] After the shut-in well operation ends and the second gate is not immediately controlled to close, that is, when the well testing device is not immediately removed from the Christmas tree, at this time, the pressure collected by the pressure gauge in the well testing device is the pressure after the shut-in well is opened. After the pressure gauge stabilizes, the second gate is closed, and then the well testing device is removed from the Christmas tree. That is to say, before the first gate is opened, the pressure collected by the pressure gauge is the pressure of the well to be tested during the shut-in well period. After the first gate is opened and before the second gate is closed, the pressure collected by the pressure gauge is the pressure of the well to be tested after the shut-in well is opened.

[0096] In summary, in the embodiments of the present application, the well testing device is placed inside the pipe wall of the Christmas tree to conduct well testing on the oil well. The Christmas tree is the Christmas tree arranged on the well to be tested, and the well testing device stores a pressure gauge. Therefore, the well testing device inside the pipe wall of the Christmas tree can conduct well testing on the oil well, thus solving the problem that the well testing device cannot be placed inside the oil well and resulting in the inability to conduct well testing. That is, the well testing device can conduct well testing on the oil well even without being placed inside the well of the oil well, and further, the pressure data of the oil well can be obtained, providing pressure data information for the later construction of the oil well.

[0097] Figure 11 It is a schematic structural diagram of a well testing device provided by an embodiment of the present application. As Figure 11 shown, the well testing device 1100 may include the following several modules.

[0098] An operation module 1101, configured to control the opening of the first gate on the Christmas tree. The Christmas tree further includes a second gate, and the distance between the second gate and the oil inlet of the Christmas tree is less than the distance between the first gate and the oil inlet of the Christmas tree. The Christmas tree is the Christmas tree arranged on the well to be tested;

[0099] A placement module 1102, configured to place the well testing device through the first gate inside the pipe wall between the first gate and the second gate of the Christmas tree. A pressure gauge is placed inside the well testing device;

[0100] A collection module 1103, configured to control the closing of the first gate and the opening of the second gate, so that the pressure gauge collects the pressure inside the well to be tested.

[0101] Optionally, the device further includes:

[0102] The operation module 1101 is further configured to control the opening of the first gate, control the closing of the second gate, and control the well testing device to move out of the Christmas tree when it is determined that the soaking time has reached.

[0103] The acquisition module 1104 is configured to acquire the pressure collected by the pressure gauge and use the pressure as the pressure of the well to be tested during the soaking time.

[0104] In summary, in the embodiment of the present application, the well testing device is placed inside the pipe wall of the Christmas tree to perform well testing on the oil well. The Christmas tree is the Christmas tree arranged on the well to be tested, and the pressure gauge is stored in the well testing device. Therefore, the well testing device inside the pipe wall of the Christmas tree can perform well testing on the oil well, thereby solving the problem that the well testing device cannot be placed into the oil well and thus cannot perform well testing, that is, the well testing device can perform well testing on the oil well even without being placed into the well of the oil well, and further, the pressure data of the oil well can be obtained, providing the information of the pressure data for the later oil well construction.
