FD-3019型γ测井仪死时间修正的必要性

摘要

死时间是FD-3019型γ测井仪的一个重要参数,笔者主要介绍死时间的定义、测量、计算和修正的方法,通过对多个钻孔测井数据死时间修正前后进行对比,并分别计算出钻孔内铀矿段含量,求出相对误差,进而说明死时间修正的必要性.%Dead time is a very important parameter of FD-3019γ logging instrument.This paper described the definition of dead time, introduced measurement,calculation and correction methods of dead time,explained the necessity of dead time correction by comparing revised data and calculated the errors of uranium content in the drill holes.
