Abstract
Description
Technical Field
[0001] This utility model relates to the field of fracturing manifold testing technology, specifically a fracturing manifold hydrostatic pressure testing device. Background Technology
[0002] Fracturing manifolds are widely used in cementing and fracturing operations in oil and gas fields. They collect the fluid pumped out by the fracturing truck and inject it into the target formation, featuring high pressure resistance and low frictional resistance. Furthermore, fracturing manifolds require regular maintenance and inspection to promptly eliminate potential hazards, ensuring their service life and operational safety. A fracturing manifold connects the high-pressure output ends of multiple fracturing trucks via high-pressure elbows and tees, and then connects to the wellhead via high-pressure pipelines. During fracturing manifold production, hydrostatic pressure testing of the high-pressure elbows is necessary to ensure the quality of fracturing manifold production.
[0003] However, existing water pressure testing equipment is difficult to adjust in terms of both the fixed structure and the testing structure, and cannot be adjusted according to different models of high-pressure elbows, which reduces the practicality of the testing equipment.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments. Obviously, the described embodiments are only some embodiments, not all embodiments. Based on the embodiments described, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.
[0024] Example 1:
[0025] Please see Figure 1-4 A hydrostatic pressure testing device for fracturing manifolds includes a support plate 1, a workbench 2 fixedly mounted on the upper part of the support plate 1, a sliding plate 3 slidably mounted on the upper surface of the workbench 2, a first hydraulic rod 4 fixedly mounted on the upper surface of the sliding plate 3, an mounting block 5 fixedly mounted on the upper end of the first hydraulic rod 4, a second hydraulic rod 6 fixedly mounted on the surface of the mounting block 5, a sealing cover plate 7 fixedly mounted on the rear end of the second hydraulic rod 6, a pressure sensor 8 mounted on the surface of the sealing cover plate 7 on the left side of the workbench 2, a water inlet 11 mounted on the surface of the sealing cover plate 7 on the right side of the workbench 2, a first bidirectional lead screw 13 rotatably mounted on the lower front part of the workbench 2, a first moving block 14 threaded on the outer sides of both ends of the first bidirectional lead screw 13, and a first motor 15 fixedly mounted on the outer side of the workbench 2.
[0026] Specifically, the mounting block 5 is set on the left and right sides, which correspond to the two inlets and outlets of the high-pressure elbow. The second hydraulic rod 6 can push the sealing cover 7 to the two ends of the high-pressure elbow, so that the water inlet 11 and the pressure sensor 8 can enter the interior of the high-pressure elbow. An air valve is set on the surface of the sealing cover 7 on the left side of the workbench 2.
[0027] Preferably, a high-pressure water pump 9 is fixedly installed on the upper surface of the support plate 1, and a connecting pipe 10 is connected to the surface of the high-pressure water pump 9. The upper end of the connecting pipe 10 is connected to the water inlet 11.
[0028] Specifically, the pump 9 has an external water source at its inlet, which can draw water and deliver it to the inlet 11 through the connecting pipe 10.
[0029] Preferably, a pressure controller 12 is fixedly installed on the upper part of the workbench 2, and the pressure controller 12 and the pressure sensor 8 are electrically connected.
[0030] Preferably, the output end of the first motor 15 is fixedly connected to the left end of the first bidirectional lead screw 13, and the upper part of the first moving block 14 is fixedly connected to the lower part of the sliding plate 3.
[0031] Specifically, the first motor 15 can drive the first bidirectional lead screw 13 to rotate, thereby causing the first moving block 14 to move. When the first motor 15 rotates counterclockwise, the first moving blocks 14 move away from each other. When the first motor 15 rotates clockwise, the first moving blocks 14 move closer to each other.
[0032] Preferably, a water tank 24 is provided on the upper part of the workbench 2.
[0033] Working principle: Fix the high-pressure elbow on workbench 2, such as... Figure 1 As shown, the sealing cover 7 is then positioned on the upper part of the water tank 24. Afterwards, the first motor 15 drives the bidirectional lead screw to rotate, the first moving block 14 moves the sliding plate 3, the sliding plate 3 moves the mounting block 5, and the mounting block 5 moves the sealing cover 7. The sealing covers 7 can move closer to or further apart, aligning with both ends of the high-pressure elbow. Then, the first hydraulic rod 4 adjusts the height of the sealing cover 7, bringing it to the same horizontal plane as the high-pressure elbow. At this point, the second hydraulic rod 6 pushes the sealing cover 7 closer to the high-pressure elbow. Plate 7 will be tightly fitted to the high-pressure elbow for sealing. Water inlet 11 and pressure sensor 8 will both enter the high-pressure elbow, so that the position of water inlet 11 and pressure sensor can be adjusted according to the different sizes of high-pressure elbows, so that the sealing cover 7 can correspond to the center of the two ends of the high-pressure elbow, enabling the detection of different models of high-pressure elbows. At the beginning of the detection, water is pumped by high-pressure water pump 9, and water inlet 11 will continuously inject water into the high-pressure elbow. As water is continuously injected, the water pressure in the high-pressure elbow will also continuously increase. Pressure sensor 8 will output data to pressure controller 12, thereby detecting the static water pressure of the high-pressure elbow.
[0034] Example 2:
[0035] Please see Figure 1-4 A movable clamping frame 16 is slidably installed on the upper surface of the workbench 2, and an adjusting clamping frame 17 is installed on the upper surface of the workbench 2. A third hydraulic rod 18 is fixedly installed on the upper surface of the movable clamping frame 16 and the adjusting clamping frame 17. An upper clamping plate 19 is fixedly installed at the lower end of the third hydraulic rod 18, and a lower clamping plate 20 is installed below the movable clamping frame 16 and the adjusting clamping frame 17.
[0036] Specifically, such as Figure 2As shown, the adjusting clamp 17 is fixed by bolts, and a corresponding threaded hole is also opened on the worktable 2 to facilitate the movement and adjustment of the clamp 17.
[0037] Preferably, a second bidirectional lead screw 21 is rotatably mounted on the lower rear part of the worktable 2, and a second moving block 22 is threaded on the outer side of both ends of the second bidirectional lead screw 21. A second motor 23 is fixedly mounted on the outer side of the worktable 2, and the output end of the second motor 23 is fixedly connected to the left end of the second bidirectional lead screw 21.
[0038] Specifically, the working principles of the second motor 23, the second bidirectional lead screw 21, and the second moving block 22 are the same as those of the first motor 15, the first bidirectional lead screw 13, and the first moving block 14 in Embodiment 1.
[0039] Working principle: When fixing the high-pressure elbow, the second motor 23 drives the second bidirectional lead screw 21 to rotate, and the second moving block 22 can drive the moving clamping frame 16 to move. After adjusting to the appropriate position, the adjusting clamping frame 17 can be manually adjusted so that the triangular positioning formed by the adjusting clamping frame 17 and the moving clamping frame 16 can adapt to different models of high-pressure elbows. After adjustment, the high-pressure elbow can be placed on the lower clamping plate 20, and then the third hydraulic rod 18 drives the upper clamping plate 19 to move downward to clamp and fix the high-pressure elbow, thereby achieving the ability to fix high-pressure elbows of different sizes and improving the practicality of the testing equipment.
