摘要
宁夏西北部山区地形复杂,浅表层地震地质条件也较为复杂,给三维地震勘探带来难度。以宁夏某山区三维地震勘探为例,针对该区具体的地震地质条件,从采集条件分析入手,采取了一系列技术措施和方法进行野外数据采集、资料处理和解释,取得较好效果,并经后期钻孔验证,其地质成果吻合度较高。
Topography in the northwest mountain area of Ningxia is complicated,there are poor superficies and shallow seismic-geologic conditions,this is quite a puzzle to 3D seismic prospecting.Taking 3D seismic prospecting in mountainous regions in Ningxia as an example,aimed at poor superficies and shallow seismic-geologic condition,first from collected condition analysis to commence.Combine with the practices,we have adopted a series of technique measures and methods in seismic data gathering,data processing and interpretation,and obtained good effects,the inosculation of the geological result was proved by later boreholes.
