博格达山山前断褶带山地地震采集方法及效果

Field Seismic Acquisition Method and Effectiveness in the Foothill Fault-fold Structural Belt of Bogda Mountain

为了研究博格达山山前断褶带的地下地质构造,进一步分析二叠系芦草沟组的分布形态,开展了二维地震勘探的试验。针对山前断褶带地下地质构造复杂,地表条件起伏大,通过大排列小道距的观测系统,获得了较好的原始资料,为山前断褶带的地震采集提供了实践经验,为山前断褶带的地下构造认识提供了可靠的地震资料。

In order to study the underground geological structure in the foothill fault-fold structural belt of Bogda Mountain,this paper makes a further analysis on the distribution of the Permian Lucaogou formation and carries the 2Dseismic exploration.In connection with the underground complex geological structure and undulating surface conditions,through the large array and a short geophone distance of observing system,it obtains better raw data and provides a practical experience of seismic acquisition for the foothill fault-fold structural belt and reliable seismic data for geological structure.
