西昌地区表层结构调查方法

Survey Methods of Surface Structure in Xichang District

利用西昌地区的表层结构调查原始数据结合野外实际地表条件进行分析,用正演模拟技术建立各种地质模型,研究西昌地区的表层结构情况。这对以后在该区进行的地震勘探合理设计井深、合理设计观测系统有实际的指导意义,从而改进激发、接收效果,并准确提供近地表静校正量,为地震资料处理提供数据。

The author had studied the surface structure of Xichang district with various geological models built by forward modeling technique based on the integrated analysis of raw data obtained from the stratum survey and the actual field circumstances.This study would be of guiding value to designing compatible well depth and monitoring system for future seismic prospecting from which the better activating and receiving efficiency coupled with accurate near surface statics correction data served as the information source for seismic data processing.
