摘要
提出重力数据处理方法技术在寻找油气田中的应用，讨论所采用的数据处理方法包括：趋势面分析、高阶导数、归一化总梯度、分离场法反演多层密度界面等的原理，并通过在多处地区试验和应用，对划分区域构造、圈定局部构造、计算沉积岩层的厚度以及对含油气远景进行评价。
We discuss the principles of four processing methods applied to gravity data processing in search of hydrocarbon: the normalized gravity gradient nethod, the high order derivative method, the trend analysis method and the method of field separation for inversion of density interfaces. Tests in several regions show that the methods are successful in defining the regional and local structures,calculating the depths of the sediments and evaluating the potential hydrocarbon reserves.
