摘　　要：介绍了油气田勘查中应用核探测技术和异常解释模式所取得的一些成果。实践表明核探测技术能快速解决油气田边界位置的确定、解释并计算油气田的埋藏深度。利用大庆油田油气化探(含放射性)资料,解释并计算了油气田的埋藏深度。经对已知油气藏35口油气化探井(其中12口为含放射性井)的检验,预测埋深与实际埋深相对误差为≥30%的井有6口,其中2口为含放射性井,为总井数的17 14%(其中含放射性井占总含放射性井的16 67%);相对误差<30%的井有29口,其中10口井为含放射性井,为总井数的82 86%(其中含放射性井占总含放射性井的83 33%)。充分证明了所建立的确定油气藏空间位置数学模型的可行性、有效性和实用性。放射性测量所用的仪器具有灵敏度高、轻便、易携带和操作简单等特点,它的异常解释处理也较为简单,效果也较好。因此,在油气田地质勘查中,它有很大的发展潜力,值得进一步开展试验、探索和研究。This paper introduces some achievements of the application nucleus measurement techniques and anomaly explanation method to the oil & gas exploration.The result shows this method can determine the location of the boundary of oil or gas field and calculate the burial depths of the reservoirs. In Daqing oilfield,by the examination of 35 wells,including 12 wells with radioactivity,there are 6 wells with the relative errors of the forecasted and actual burial depths more than 30 percent, about 17.14 percent of the total. There are 29 wells with the relative errors less than 30 percent, amount to 82.86 percent of the total.It is proved that the mathematical model determining the location of reservoir is feasible, valid and useable. Nucleus measurement technique is a kind of high-tech.With its sensitivity, portability, operability and efficiency,it has a great developmental potential, worth of investigating,testing and studying further.
