HT-1旋转式井壁取心仪保护监测系统原理及其干扰抑制

Principle and Interference Suppression of Protection Monitoring System of HT-1 Rotary Sidewall Coring Tool

HT-1旋转式井壁取心仪内设置了保护监测装置,其主要功能是对井下探头缺油状况和灌浆状况进行监测,保护监测过程由硬件电路和软件控制共同完成。外界干扰信号会影响保护监测电路的正常工作。结合仪器原理,介绍了一系列抑制保护监测干扰的措施。

The main function of protection monitoring device inside HT-1 rotary sidewall coring tool is monitoring the low oil condition and grouting condition.The protection monitoring process is completed with the aid of hardware circuit and soft-ware control.The outside interference signal will influence the regular work of protection monitoring circuit.Combined with the operational principle of coring tool,the article introduces a series of suppression precautions against the interference in protection monitoring circuit of HT-1.
