用地面小褶曲辅助地震资料构造解释

Using the Little Fords on Surface to Assist Seismic Data to Interpret Structures

本文以川东地面小褶曲和局部大构造具有相似性和可比性为基础,将小褶曲剖面形态与大构造的地震解释剖面形态进行对比、分析,认为川东大小构造一般均符合同心褶曲垂向变化规律,在一定程度上,可用小构造形态辅助地震资料的构造解释,有助于建立局部构造地质模式,正确解释地腹构造、断裂形态。

In this paper, based on the similarity and comparative property between the little folds and the lo- cal large structures on surface in East Sichuan, it is recognized that the large structures and little struc- tures in East Sichuan are all coincidence with the vertical variable rule of concentric fold, comparing and analyzing the section features of the little folds and large structures interpreted with seismic data. To a certain extent, it is able to use the little fold features to assist the seismic data to interpret struc- tures, and favorable to set up the geological model of local structures to correctly interpret subsurface siructures and fault features.
