岩性密度测井仪能谱测量工作原理及故障维修

摘要

岩性密度测井仪是石油测井中的重要仪器,在判断岩性、确定地层孔隙度等方面有重要应用.以阿特拉斯2228仪器为例分析了能谱测量电路工作机制,测量了其信号时序,列举了故障案例,为故障维修提供了一定参考.%Lithology density logging tool is an important instrument in oil logging.It has important application in judging lithology and determining the porosity of formation.This paper takes Atlas 2228 instrument as an example to analyze the working mechanism of energy spectrum measurement circuit,the signal timing measurement.The fault cases are enumerated,which provide some reference for the fault maintenance.
