摘　　要：通过对大庆油田丰富的地表油气化探、钻井资料分析研究,结合油藏放射性异常模型,提出了氡异常水平分布及特征值与油气藏深度的关系数学模型及参数计算方法。通过大庆油田杜29井区实际资料验证和平洋来27井区、来36井区试验应用,证实用地表油气化探特征值估算确定油气田埋藏深度的技术方法是可行、实用的。而这种解释结果结合地质解释分析,对指导油气田勘探部署,提高勘探效益都具有实际意义。Basing on the geochemical exploration data and boring data in Daqing oil field as well as referring oil reservoir radioactive singularity model,this paper gives a model between radon distribution on surface and the depth of oil reservoir.The real data in Daqing Du 29# oil well confirm this model.we also apply this model on Daqing Lai 27# and Lai 36# oil well sand the results show that the depth of oil reservoir could be reasoned out from radon geochemical exploration data.This model can help oil exploration and raise exploration efficiency combining geologic survey.
