Problems solved by technology
[0005] For the above-mentioned existing technologies or newly developed mud pulsers, the key lies in the system tightness to meet the requirements. However, in the prior art, the system tightness test operation during the mud pulser processing is mostly completed by manual sampling, which not only has low detection efficiency, but also It takes a long time, and the detection is labor-intensive, high-cost, and poor in practicability

The invention discloses a mud pulser system sealing performance testing device and method. The mud pulser system sealing performance testing device comprises a machine body, a testing mechanism and acontrol panel; an observation window is formed in the upper end of the front side surface of the machine body, an adjusting rod is transversely arranged on the top surface of the machine body on the outer side of a detection water tank through a rotating arm, and a telescopic rod is disposed on the surface of one side, far away from the adjusting rod, of a rotary disc; the testing mechanism comprises a positioning chuck, a pressurizing air gun and a CCD camera, a circular-truncated-cone-shaped air guide cylinder is fixedly arranged in the middle of the side face of the positioning chuck through a through hole, and the pressurizing air gun is arranged in the middle of the surface of the side, away from the air guide cylinder, of the positioning chuck; the control panel is transversely arranged at the upper end of the front surface of the machine body. Feeding is completed through cooperation of the rotating arm and movement of the rotary disc, precise down-regulation of the positioningchuck is completed under the action of the telescopic rod, the pressurizing air gun injects external air into a pipeline of the pulser quantitatively through the air guide cylinder, the bubble amountis observed through the CCD camera to judge the overall air tightness, and the using effect is good.
Description
technical field [0001] The invention relates to the technical field of petroleum drilling, in particular to the technical fields of measurement-while-drilling and logging-while-drilling during the drilling process, in particular to a mud pulser system leak test device and a test method. Background technique [0002] Information about hydrocarbon producing formations is typically obtained during operations performed in boreholes that intersect the formations. Typical wellbore operations also include gathering downhole information, including measurement while drilling (MWD) and logging while drilling (LWD). Formation information typically includes downhole fluid pressure and / or temperature, as well as information about the formation, such as resistivity, density, tool orientation and location, and porosity. Information obtained during measurement-while-drilling and measurement-while-drilling is usually transmitted to the surface in real time through mud pulse telemetry, and t...
