Description

Technical Field

[0001] The utility model relates to the technical field of tubing pressure testing, in particular to a tubing pressure testing and detecting device. Background Technique

[0002] A tubing is a pipeline used to transport crude oil and natural gas from an oil and gas layer to the surface after drilling is completed. During the use of the tubing, a relatively large pressure will be generated, so it is necessary to use a pressure detection device to detect the internal pressure of the tubing.

[0003] After long-term use, the tubing is extremely vulnerable to corrosion by various elements, which weakens the pressure-bearing capacity of the tubing. The pressure testing device conducts a hydrostatic pressure test on the tubing under the required pressure conditions by screwing and sealing the two ends of the tubing and injecting water, so as to achieve the purpose of testing the pressure resistance and sealing ability of the tubing.

[0004] Most of the pressure testing and detecting devices clamp and inject water at both ends of the tubing, and the middle of the tubing does not have a support and limit function, resulting in deformation of the tubing when the pressure testing and detecting device detects the pressure of the tubing, and it cannot well meet the use requirements. Therefore, a tubing pressure testing and detecting device is proposed to solve the above-mentioned problems. Content of the Utility Model
