近年来,苏联和其他各国在油,气田普查工作中开始采用放射性方法,油藏上部所观察到的放射性测量异常,并不决定于放射性元素的某种特性,而是油田本身所特有的普通地球化学环境的一种特殊表现.放射性元素唯一的特点就是能够使用核子物理方法测出它们的最低含量.放射性测量方法之所以能够得到广泛采用,其主要优点是在灵敏度极高的情况下测量简单和迅速,用这样高的灵敏度的仪器使我们能够对岩石和表土中放射性元素自然分布的变化情况进行观察.
In recent years, the Soviet Union and other countries began to adopt radioactive methods in the oil and gas census work. The observed radioactive abnormalities in the upper part of the reservoir are not determined by certain characteristics of the radioactive elements but by ordinary earth A special manifestation of the chemical environment. The unique feature of radioactive elements is the ability to use nuclear physics to measure their minimum content .Radio-measurement methods are widely used, the main advantage is the measurement of high sensitivity simple and Rapidly, using such high-sensitivity instruments enabled us to observe the changes in the natural distribution of radioactive elements in rock and topsoil.
