摘　　要：对油气化探异常确定与解释中的若干问题进行了探讨,强调油气化探异常的确定必须充分了解化探数据的统计分布与空间分布特征,并采取相应的异常确定方法;异常的解释与评价需融合油气地质基础资料,采用系统的评价思路与方法,揭示化探异常与油气分布之间的联系。A number of problems are discussed in this paper concerning the determination and interpretation of the oil and gas geochemical anomalies. It is emphatically pointed out that the characteristics of the statistical distribution and spatial distribution of geochemical data should be fully understood when the oil and gas geochemical anomalies are determined,and appropriate methods should be adopted to determine anomalies. The interpretation and evaluation of the oil and gas geochemical anomalies should be combined with the basic geological data,and systematic train of thought and methods of evaluation ought to used to reveal the link between the geochemical anomalies and hydrocarbon distribution.
