The parameter acquisition system of oil drill’s bit in working process

Abstract

In the process of oil drilling, it is often required to improve the drilling efficiency and to be able to analyze the faults in the drilling process, so it is of great significance to study the parameter acquisition system of the oil drill bit working process[1]. Aiming at this situation, this paper designs a device for downhole data acquisition, vibration detection, temperature detection and rotational speed detection of deep well drill bits. In this paper, an overall scheme is designed, and the acceleration[2], on-board temperature [3]and rotational speed[4] of the three axes of X, Y, and Z are selected as the main measurement objects. The working parameters of the drill bit can not only reflect the entire working condition of the drill bit, but also can be used for failure analysis during the drilling process. Provide strong evidence. First of all, components need to have high temperature resistance characteristics. At the same time, the selected components can meet the detailed parameters of technical requirements, including measurement range, measurement accuracy, resolution, etc. Secondly, design the hardware circuit, including acceleration acquisition circuit, temperature measurement circuit, rotational speed measurement circuit and data storage circuit. Finally, the software is designed, including the data acquisition, the A/D conversion and the Flash stored program design.
