摘　　要：随着油田复杂井、大位移水平井越来越多,油田用户对测井仪器的作业安全性和方便性要求也越来越高,存储式变密下井仪器通过钻具的上提、下放进行时间、深度、与变密度等信号的采集和存储,完成无电缆测井。文章概述了一种存储式变密度下井仪器的工作原理、电路实现及实际应用。Oilfield complex wells and horizontal wells are utilized increasingly.The safety and operability of logging instruments are required significantly and strictly.The storage-type variable density down-hole instrument can accomplish well logging without cable by means of raising and lowering the drill so that the information about time,depth,and the signal of density can be collected.This article summarizes the principles of Storage-type variable density down-hole instrument,the implementation of the instrument circuit,and its applications.
