Problems solved by technology
[0003] Since the measuring transmission motor is used in a harsh environment, it is easy to be ineffective due to downhole mud being poured into the gap of the measuring transmission motor. Therefore, frequent maintenance and inspection are required. In the prior art, the inspection and maintenance of the measuring transmission motor is manually operated. The operation process is complicated and it is easy to operate improperly. As a result of frequent drilling equipment problems, how to simulate the downhole environment for automatic maintenance is becoming more and more important in the process of troubleshooting in engineering

Description
technical field [0001] The invention relates to the field of logging while drilling equipment maintenance, in particular to a near-bit measurement and transmission motor maintenance device and a maintenance method. Background technique [0002] The near-bit geosteering system has three functions of measurement, transmission and steering. The system includes: drill bit, measurement and transmission motor (including near measurement instrument assembly), wireless short transmission, MWD / LWD measurement system, and ground processing system. The measuring motor is a fully instrumented steering motor that is directly connected to the drill bit. It is a capsule specially designed to carry speedometers, gamma meters and other instruments, batteries and circuits. The integrated sensor components measure geological parameters such as gamma and resistivity near the drill bit and engineering parameters such as well inclination and tool face angle, and transmit the measured near-bit pa...
