Pipe body pressure test device and pipe body pressure test method

Abstract

The invention relates to a pipe body pressure test device comprising a top disc and a bottom disc which are coaxially arranged and connected, and a cavity is defined between the top disc and the bottom disc; the upper pressure testing disc and the lower pressure testing disc are located in the cavity and arranged at the top disc and the bottom disc, and the upper pressure testing disc and the lower pressure testing disc are used for being connected with the end face of the pipe body, so that the upper pressure testing disc and the lower pressure testing disc can form a pressure testing space together with the pipe body; and the pressure test nozzle is arranged on the top tray and is communicated with the pressure test space. The pipe body pressure testing device is easy to operate, the pipe body does not need to be fixed by assembling and disassembling threads, and the pressure testing efficiency is high. And meanwhile, the device can be suitable for pipe bodies with various standard sizes.

Description

technical field [0001] The invention relates to the field of oil exploitation, in particular to a pipe body pressure test device and a pipe body pressure test method. Background technique [0002] With the development of petroleum drilling tools, especially the rapid development of petroleum solid completion tools, in order to ensure the safety of downhole applications of tubular solid completion tools, it is often necessary to complete the assembly of petroleum solid completion tools Sealing test to verify the assembly sealing performance of the tool. [0003] At present, the pressure testing devices of cementing and completion tools such as floating hoop shoes and graded cementing devices often use threaded male end heads and female end heads, which are connected with tubular cementing and completion tools through threads. Alternatively, special pressure test fixtures suitable for different tool inner diameters can also be used for testing. [0004] On the one hand, thes...

AI Technical Summary

Problems solved by technology

[0004] On the one hand, these traditional pressure test methods have the characteristics of specialization, poor versatility, and cannot meet the pressure test requirements of different specifications and different types of products.

On the other hand, when replacing the tested pipe body, it is often necessary to install and remove the threads many times. This method is time-consuming and laborious, resulting in low efficiency of the pressure test.
