Embodiment 1

[0026] In order to solve the problem that in the prior art, only vacuum pumping can be used for airtightness testing, and the airtightness is tested under negative pressure. The test pressure is only 1Mpa, which is difficult to meet the airtightness requirements under high pressure. The invention provides a positive pressure tightness test device, specifically, refer to figure 1 and figure 2 , the device includes a sleeve 6, a sealing joint 5, a pressing device 1 and a quick joint 7, the sleeve 6 includes a sealing end 61 and an opening end 62, and the sealing joint 5 and the opening end 62 of the sleeve 6 Threaded connection, the pressing device 1 is set on the sealing joint 5 through the quick joint 7, the quick joint 7 is provided with a pressure valve 8, and the sealing joint 5 is provided with a pressure gauge 3.

[0027] Further, the pressing device 1 is provided with a handle, which is convenient for manual pressing.

[0028] Specifically, the sealing end 61 of the s...

Embodiment 2

[0039] This embodiment has provided another group of sealing instructions that utilize this sealing test device to test, such as figure 1 and figure 2 As shown, it includes a sleeve 6, a sealing joint 5, a pressing device 1 and a quick joint 7. The sleeve 6 includes a sealing end 61 and an opening end 62, and the sealing joint 5 is threaded with the opening end 62 of the sleeve 6. The pressing device 1 is set on the sealing joint 5 through the quick joint 7, the quick joint 7 is provided with a pressure valve 8, and the sealing joint 5 is provided with a pressure gauge 3.

[0040] Further, the pressing device 1 is provided with a handle, which is convenient for manual pressing.

[0041] Specifically, the sealing end 61 of the sleeve 6 is integrally formed with the sleeve 6 and then sealed, and the opening end 62 of the sleeve 6 is provided with an external thread, and the opening end 62 of the sleeve 6 is fitted together. The inner side of the sealing joint 5 is provided wi...

Abstract

The present invention relates to the sealing performance detection technology field, and discloses a positive pressure sealing performance test device. The positive pressure sealing performance test device comprises a sleeve, a sealing joint, a pressing device and a rapid joint, the sleeve comprises a sealing end and an opening end, and the sealing joint is in threaded connection with the openingend of the sleeve. The pressing device is connected with the sealing joint via the rapid joint, the rapid joint is equipped with a pressure valve, and the sealing joint is equipped with a pressure gauge. The positive pressure sealing performance test device of the present invention can test the sealing pressure reaching up to 120 Mpa, and solves the problems in the prior art that for the LWD sealing performance detection, the sealing performance only can be tested under the negative pressure in a vacuumizing manner, the test pressure is only 1 Mpa, and the sealing performance requirements under the high pressure are difficult to satisfy.

Description

technical field [0001] The invention relates to the technical field of airtightness testing, and discloses a positive pressure airtightness testing device Background technique [0002] LWD (LoggingWhileDrilling) means "logging while drilling". Generally speaking, in addition to the measurement parameters of MWD, it must also include all or part of geological parameters (such as: resistivity while drilling, gamma while drilling, density, while drilling porosity, etc.) [0003] LWD technology is mainly used in the occasions of distinguishing formations, distinguishing oil, gas and water, judging formation changes, and predicting high-pressure formations, etc. It can greatly shorten the drilling cycle, reduce the soaking time of oil and gas, and reduce the pollution of oil layers. Since the application occasions of LWD instruments are mostly underground high-pressure test environments, strict requirements are put forward for the sealing of LWD instruments. If the sealing of LW...
