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

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