摘　　要：油气化探异常圈闭评价在油气资源勘探中发挥着重要作用。作者提出基于RBF(高斯径向基核函数)的油气化探异常圈闭评价法,应用于油气化探异常检测和评价,克服了综合油气化探异常解释中化探信息分散,异常信息层次不明显,尤其是多化探信息融合权值难以确定的问题。将该方法应用于塔北雅克拉测区的油田综合化探异常检测和分析,结果表明该方法具有提取的综合油气化探信息异常特征明显、层次分明,异常形态清晰,异常走向明晰等特点。Verification and evaluation of geochemical prospecting anomalies played a significant role in exploration of oil and gas reservoirs. To solve the problems of dispersion, distinction of levels and especially the determination of the weighting of attributes of the multi-attribute geochemical data, an approach based on RBF (RBF Gaussian kernel) was applied to the verification and evaluation of oil and gas geochemical prospecting anomalies in this paper. With experiment on an oil and gas research area in north-west of China, this approach is proved to be effective to avoid the problems mentioned above.
