Abstract

An oil drilling drill string online monitoring system and a fault diagnosis method belong to the oil drilling monitoring technology. Including PCB board, upper computer, torque sensor and acceleration sensor connected to the drill string respectively, the torque sensor and acceleration sensor are respectively connected to the PCB board, and the collected torque signal and vibration signal are sent to the PCB board, and the PCB board will pre- The processed data communicates with the host computer through the Bluetooth module. The patent of the invention has good portability, can monitor the drilling state of the drill string in real time, and can accurately and reliably diagnose abnormal conditions, so that drilling workers can take remedial measures in time and effectively prevent dangerous accidents.

Description

technical field [0001] The invention belongs to oil drilling monitoring technology, in particular to a drilling tool monitoring system and a fault diagnosis method in the oil drilling process. Background technique [0002] At present, the domestic prediction and analysis of engineering accidents that may occur during the drilling process of drilling tools is mainly done by measuring and analyzing abnormal changes in various drilling engineering parameters. The accuracy of the test system is not high and most of them can only The measured data is compared before and after according to manual experience to diagnose possible faults. This method is not only inefficient, but also has low accuracy, which may easily lead to misjudgment. Therefore, it is necessary to propose a system that can monitor the drilling state of the drilling tool in a timely, accurate and reliable manner. It is necessary to give an alarm to the abnormal situation that occurs when the drilling tool is drill...
