Research on functional testing system of mechanical section in oil logging devices

摘要

Logging devices could finish comprehensive evaluation in geologic setting, which is important for testing strata pressure, sampling formation fluid and etc. Mechanical section plays a very important role in logging devices, which could take charge of logging devices' acting and sampling. Now, it remands to monitor states of mechanical section. And an efficient testing system could be used in monitoring and maintaining mechanical section. A testing system used for monitoring mechanical couplings based on CAN bus in logging devices is explained in the paper, which could solve the problems about testing, detecting and maintaining of mechanical section better. The system has wide prospect of market application.
