Abstract

The invention discloses an online oil-drilling drill string monitoring system and a fault diagnosis method and belongs to the technique of oil drilling monitoring. The online oil-drilling drill string monitoring system comprises a PCB (printed circuit board), an upper computer, a torque sensor and an acceleration sensor, the torque sensor and the acceleration sensor are respectively connected with a drill string and the PCB and transmit collected torque signals and vibration signals to the PCB, and the PCB communicates with the upper computer with data subjected to pre-processing through a Bluetooth module. By the arrangement, transplantation is good, drilling state of the drill string can be monitored in real time, and abnormal conditions can be subjected to fault diagnosis accurately and reliably, so that convenience is brought to drilling personnel to take remedial measures timely, and occurrence of dangerous accidents is effectively prevented.

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. technical background [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...
