摘要
在复杂构造地区,由于受不同时期构造运动的影响,地层在三维空间的展布变化很大,其速度在纵向和横向上变化也很大,以及各类大小断层存在,给高精度成图和准确落实圈闭带来了极大的困难。针对龙虎庄地区地质条件复杂的情况,通过建立高精度三维空间速度场技术,解决其成图精度低的问题,并且在应用中取得了良好效果。
In complex geological structure areas,the strata were changed dramatically in three-dimensional space distribution due to the influence of different periods of the tectonic movement.Its velocity changes were highly different vertically and horizontally,therefore the existence of different faults of various shapes induced great difficulty for high precision diagrams and trap interpretation.In allusion to the situation of complex geological conditions in Longhuzhuang Area,the problem of low precision of imaging is solved by using high precision 3D space velocity field and good result is achieved in application.
