摘要
本文通过江苏刘庄油气田、湖北高场油田放射性异常特征研究,总结出断层-地层油气田上方地表放射性异常一般模式,即油气田正上方为低值异常,而周围发育环状高值晕圈,并从烃类气体垂直上移理论、油气区放射性元素地球化学性状等角度,阐明了油气田上方地表放射性异常形成机理。
Through studies of radioactivity anomaly characteristics above LZ oil/gas field and GC oil field in this paper,the author suggests a general model a- bout surface radioactivity anomaly above a fault-stratigraphic oil/gas field, i.c.,lower surface radioactivity directly above the oil/gas field and a higher surface radioactivity ring around the oil/gas field.On the basis of the vertical migration of hydrocarbon gas and geochemical property of radioactive element in oil/gas area,an explanation of the mechanism of the formation of surface radioactivity anomaly above an oil/gas field is presented,
