摘　　要：断层圈闭油气藏受断层控制,其放射性异常形式有特殊性。通过对断层圈闭油藏上放射性异常形成机理的探讨,提出断层圈闭油气藏上放射性异常的形式,并对延吉盆地油藏测量剖面上放射性异常特征进行分析,总结出断层圈闭油藏上放射性异常模式。The faults-enclosed oil/gas accumulation is controlled by faults, and the radioactive anomaly model above the oil/gas accumulation has its unique characteristics. Based on a discussion on the mechanism governing the formation of radioactive anomaly, this paper puts forward a radioactive anomaly pattern above the faults-enclosed oil/gas accumulation. An analysis of the radioactive anomaly characteristics of the radiometric profile above an oil accumulation in Yanji basin shows that the radioactive anomaly pattern above the faults-enclosed oil/gas accumulation does exist.
