TDC综合录井仪的泥浆体积测量电路

Circuit for Measuring Mud Volume In the TDC Synthetic Well Logging Instrument.

测量泥浆池中泥浆体积的变化对于安全钻井 ,控制井涌、井漏具有十分重要的意义。综合录井仪采用了完全相同的浮子式传感器测量电路对多个泥浆池中泥浆的体积进行测量。文章介绍了测量电路的工作原理 ,并对电路进行了定性、定量的分析。

It is very important to measure the volume change of mud in mud pit for the safe drilling,the control of well blowout and the lost of circulation. TDC synthetic well logging instrument can measure the volume change of mud in several mud pits at the same time. This paper describes the work principle of the instrument curcuits, and gives the qualitative and quantitative analysis of the circuits.
