[0002] Oil and gas wells are an important branch of petroleum and natural gas engineering, used for the exploration and development of underground oil and gas resources. They can be classified into various types according to drilling methods, purposes, and depths, such as vertical wells, deviated wells, and horizontal wells. Oil and gas well engineering involves multiple stages, including drilling, completion, surveying, and testing.
[0003] Currently, widely used oil and gas well testing equipment relies mainly on operators to manually adjust the position and angle of the equipment when testing various parameters of the well wall. The equipment is difficult to adjust the testing position autonomously according to the actual conditions of different areas of the well wall, requiring repeated manual intervention. On the other hand, due to the reliance on manual operation, the testing process is time-consuming and the overall work efficiency is relatively low. Therefore, this utility model proposes an oil and gas well testing equipment to solve the above problems. Utility Model Content

[0024] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0025] Reference Figures 1-4 As shown, an oil and gas well testing device includes an extension ring 1. A top plate 2 is fixedly connected to the inner wall of the extension ring 1. An air pump 3 is fixedly installed on the lower surface of the top plate 2. The output end of the air pump 3 is connected to an annular gas pipe 4. The outer surface of the annular gas pipe 4 is fixedly connected to the lower surface of the top plate 2. Multiple branch pipes 5 are connected inside the annular gas pipe 4. An extension plate 6 is connected through the outer surface of each branch pipe 5 and is connected to an air bladder 7. A U-shaped plate 8 is rotatably connected to the outer surface of the extension plate 6. A reversing motor 9 and a drive motor are fixedly installed on the upper surface of the U-shaped plate 8. The output end of the reversing motor 9 is connected through the interior of the U-shaped plate 8 and fixedly connected to the adjusting gear set 11. The output end of the drive motor 10 is connected through the interior of the U-shaped plate 8 and fixedly connected to the drive wheel 17. The outer surface of the adjusting gear set 11 is connected to the extension plate 6 through the transmission rod 18. The outer surface of the extension plate 6 is set on the inner wall of the extension ring 1, and the outer surface of the transmission rod 18 is connected through the interior of the U-shaped plate 8. The outer surface of the airbag 7 is fixedly connected between the inner wall of the extension ring 1 and the outer surface of the extension plate 6.
[0026] Specifically, the top plate 2 and the air pump 3 installed on the lower side of the top plate 2 are fixed by the extension ring 1, so that the air pump 3 can operate stably and send gas into the interior of the annular gas pipe 4. At the same time, the gas is dispersed into the interior of multiple diversion pipes 5 through the annular gas pipe 4. The position of the diversion pipes 5 is fixed by the extension plate 6. The gas pumped by the air pump 3 is sent into the interior of the air bag 7 through the diversion pipes 5 that pass through the extension plate 6. The air bag 7 pushes one end of the extension plate 6 to move towards the center of the extension ring 1. At the same time, the bearing on the extension plate 6 restricts the position of the extension plate 6 inside the extension ring 1, so that the other end of the extension plate 6 moves outward. This drives the U-shaped plate 8 and the transmission rod 18 connected to the extension plate 6 to move. Thus, the equipment can be fixed in the well wall by multiple drive wheels 17. At the same time, the U-shaped plate 8 controls the reversing motor 9 and the drive rod 18. The drive motor 10 is fixed so that the reversing motor 9 and the drive motor 10 can operate stably. The reversing motor 9 drives the adjusting gear set 11 to operate. At the same time, the U-shaped plate 8 fixes and restricts the position of the adjusting gear set 11, so that the adjusting gear set 11 can drive the U-shaped plate 8 to rotate. The U-shaped plate 8 is connected to the extension plate 6 through the transmission rod 18, so that the U-shaped plate 8 can rotate around the transmission rod 18 on the outside of the extension plate 6. The reversing motor 9 drives the adjusting gear set 11 to rotate the U-shaped plate 8, thereby adjusting the direction of the drive wheel 17 to move to different positions. At the same time, the drive motor 10 mounted on the U-shaped plate 8 drives the drive wheel 17 in the middle of the U-shaped plate 8 to operate, thereby driving the extension ring 1 to adjust its position, so that the well wall at different positions can be tested.
[0027] Reference Figures 4-6 As shown, a limiting mounting plate 15 is fixedly connected to the lower surface of the extension ring 1, and a base plate 14 is fixedly connected inside the limiting mounting plate 15; the base plate 14 is fixedly connected to the lower surface of the extension ring 1, and a servo motor 13 is fixedly mounted on the upper surface of the base plate 14; the output end of the servo motor 13 is connected through the interior of the base plate 14 and fixedly connected to a threaded plate 12, and the outer surface of the threaded plate 12 is disposed inside the limiting mounting plate 15; multiple sliders 16 are slidably connected inside the limiting mounting plate 15, and each slider 16 is engaged with the threaded plate 12; the outer surface of the servo motor 13 is fixedly connected to the interior of the top plate 2;
[0028] Specifically, the limiting mounting plate 15 is fixed by the extension ring 1, and the lower side of the limiting mounting plate 15 is sealed by the base plate 14 to prevent water from entering and causing malfunctions. At the same time, the servo motor 13 installed inside the threaded plate 12 rotates, thereby driving the threaded plate 12 inside the limiting mounting plate 15 to rotate. This allows the threaded plate 12 to drive multiple sliders 16 installed on the lower side of the threaded plate 12 to move synchronously. Meanwhile, the probes installed on the sliders 16 test the well wall.
[0029] Working principle: When in use, the equipment is placed inside the oil and gas well through the wellhead. At the same time, the air pump 3 between the top plate 2 and the threaded plate 12 is operated, and the gas is sent into the airbag 7 through the annular pipe 4 and the diverter pipe 5. The airbag 7 can push one end of the extension plate 6 towards the center of the extension ring 1, and then push the other end outward. This pushes the U-shaped plate 8 and the drive wheel 17 outward, and the multiple drive wheels 17 support the extension ring 1 to prevent it from sliding down.
[0030] Subsequently, the reversing motor 9 and the drive motor 10 are started. The reversing motor 9 drives the adjusting gear set 11 to rotate, and the adjusting gear set 11 drives the transmission rod 18 to rotate, so that the U-shaped plate 8 rotates around the transmission rod 18, thereby driving the drive wheel 17 to adjust its position. This allows the direction of travel of the drive wheel 17 to be controlled. At the same time, the drive motor 10 drives the drive wheel 17 to rotate, which can control the rotation and movement of the extension ring 1, thereby allowing testing at different locations of the oil and gas well.
[0031] The servo motor 13 installed between the top plate 2 and the threaded plate 12 is started. The servo motor 13 drives the threaded plate 12 inside the limit mounting plate 15 to rotate. The threaded plate 12 pushes the multiple sliders 16 that are meshed with it outward, so that the probes installed on the sliders 16 can contact the well wall and thus test the well wall. At the same time, the extension ring 1 on the upper side rotates, so that the probes can perform all-round testing on the well wall, thereby ensuring the stability of the well wall and preventing damage.
[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
