Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water pressure testing, in particular to a water pressure testing device for high-pressure water injection pipelines in oil fields. Background Technique
[0002] The high-pressure water injection pipeline in the oil field is a pipeline system that transports high-pressure water from the water source to the oil field. During the oil field exploitation process, as the production of oil wells gradually decreases, a series of production-increasing measures need to be taken to maintain or increase the production of the oil field. One of the commonly used methods is to inject high-pressure water into the oil wells to increase the pressure of the oil reservoir and push the crude oil to flow towards the wellhead. During the use of the high-pressure water injection pipeline in the oil field, it is necessary to conduct a water pressure test on it. Therefore, a water pressure testing device is needed.
[0003] During the use of traditional pipeline water pressure testing devices, they can only detect pipelines of the same specification. When pipelines of different specifications need to be detected, different detection devices need to be replaced, which reduces the practicability of the device. Moreover, during the pressure detection process, the two ends of the pipeline are usually squeezed and sealed. During the squeezing process, the middle part of the pipeline is prone to bending, causing deformation at both ends of the pipeline, reducing the sealing effect and affecting the accuracy of the detection value. Content of the Utility Model
[0004] The purpose of the utility model is to solve the defects existing in the prior art, and a water pressure testing device for high-pressure water injection pipelines in oil fields is proposed.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0006] A water pressure testing device for high-pressure water injection pipelines in oil fields, including an operating platform. Two connecting seats are arranged on the top of the operating platform. Circular platforms are fixed on the inner side walls of the two connecting seats. A through hole is opened at the top of one of the circular platforms, and the through hole penetrates the bottom of one of the circular platforms. Rubber sleeves are sleeved on the outer side walls of the two circular platforms. Sealing rings are fixed on the outer side walls of the two rubber sleeves, and both of the two sealing rings are spiral. A power mechanism for moving the two connecting seats is arranged on the top of the operating platform. A fixing mechanism for fixing the high-pressure water injection pipeline in the oil field is arranged on the top of the operating platform. A detection mechanism for detecting the water pressure of the high-pressure water injection pipeline in the oil field is arranged on the top of the operating platform. During the use of this device, water pressure tests can be conducted on water injection pipelines of different specifications, increasing the practicability of this device. During detection, the power mechanism drives the two connecting seats to approach each other, and then drives the two circular platforms to approach each other, squeezing the two ends of the water injection pipeline. The more the two circular platforms approach each other, the greater the deformation of the rubber sleeve. Cooperating with the sealing ring, the better the sealing effect of the two ends of the water injection pipeline, and the more accurate the detection result.
[0007] As a further solution of the present utility model, the power mechanism includes a motor. Two support plates are fixed to the top of the operating table. A bidirectional lead screw is arranged on the top of the operating table, and both ends of the bidirectional lead screw are rotatably connected to the two support plates respectively. The motor is fixed to the side wall of one of the support plates, and the output shaft of the motor is fixed to the bidirectional lead screw. The same slide bar is fixed to the inner side walls of the two support plates, and the slide bar is parallel to the bidirectional lead screw. Sliders are sleeved on both symmetric ends of the slide bar. First threaded holes are formed in the side walls of the two sliders, and both of the two first threaded holes are adapted to the bidirectional lead screw. The two sliders are respectively fixed to the two connecting seats. Driving the motor to drive the bidirectional lead screw to rotate, and cooperating with the two sliders to approach each other, thereby driving the two connecting seats to approach each other. The two connecting seats approaching each other drive the two frustums to approach each other, so that water injection pipes of different specifications can be clamped and fixed, and thus water injection pipes of different specifications can be detected, increasing the practicability of the device.
[0008] As a further solution of the present utility model, the fixing mechanism includes a bracket. The bracket is fixed inside the operating table, and the bracket is located at the middle of the two support plates. A sleeve is fixed to the top of the bracket. A plurality of second threaded holes are formed in the side wall of the sleeve at equal intervals in a circular shape. A plurality of threaded rods are arranged on the side wall of the sleeve at equal intervals, and the plurality of threaded rods correspond to the plurality of second threaded holes one by one. One ends of the plurality of threaded rods are rotatably connected to arc-shaped plates, and hand wheels are fixed to the other ends of the plurality of threaded rods. By rotating the plurality of threaded rods, the plurality of arc-shaped plates are driven to contact the surface of the water injection pipe, preventing the water injection pipe from being bent and leaking during the extrusion process, which affects the detection.
[0009] As a further solution of the present utility model, the detection mechanism includes a water tank. The water tank is fixed to one end of the top of the operating table. A high-pressure water pump is fixed to the inner bottom of the water tank. A hose is fixed to the water outlet of the high-pressure water pump.

During detection, the power switch of the high-pressure water pump is turned on, and the water in the water tank is injected into the water injection pipe through the hose and the through hole by the high-pressure water pump until the water injection pipe bursts.
[0010] As a further solution of the present utility model, a check valve is arranged on the side wall of the hose. By the function of the check valve, the water in the water injection pipe is prevented from flowing back, ensuring the pressure inside the water injection pipe.
[0011] As a further solution of the present utility model, a pressure gauge is arranged on the side wall of the hose. When the water injection pipe bursts, the value displayed by the pressure gauge is the maximum water pressure that the water injection pipe can withstand.

The more the two frustums approach each other, the greater the deformation of the rubber sleeve. Cooperating with the sealing ring, the better the sealing effect of both ends of the water injection pipe, and the more accurate the detection result. Description of the Drawings
