放射性测氡法直接寻找油气藏及我国西部油气探区实例分析

Radioactive Radon Determination as a Direct Method of Prospecting for Hydrocarbon Accumulations, with Special Reference to Its Applications in Prospective Areas in West China

本文介绍了放射性方法寻找油气藏的基本原理,提出了油气藏上方放射性异常成因的温压流体垂直运移模式,指出环带状异常是放射性异常(同指其他化探指标)的基本异常模式,并对半环状异常的成因提出了新的观点,最后介绍了新疆若干探区的放射性异常实测效果。

This paper introduces the basic principles of prospecting oil and gas accumulations with the method of radioactive determination, and proposes that the formation of a radioactive abnomality above the oil and gas accumulation results from the vertical fluid migration under some given ternperature and pressure, and that the ring abnomality pattern is the basic pattern of radioactivc abnomalities (and other geochemical prospecting parameters). A new view is proposed concerning the origin of half-ring abnomalities. Finally, some results are presented that have been obtained from the application of the radioactive prospecting method in some areas in china.
