摘要
桩西古潜山带经历了长期、复杂的地质演化过程 ,形成了地下复杂构造和速度突变带 ,用常规时间偏移资料很难得到潜山的地质信息。文中利用国产三维叠前深度偏移并行软件进行了并行处理 ,偏移结果归位准确 ,对地质体成像有明显的改进。可合理解释古潜山内部构造 ,获得的两个有利含油圈闭 。
Forming complicated structure and severe changes in velocity in subsurface because of complicated geological evolution of buried hills in Zhuangxi area,the ordinary time migrated seismic data are difficult to acquir geological information of buried hills.Using home made parallel 3 D pre stack depth migration software to parallel process the data,we obtained migration results with correct position and significant improvement on imaging complicated structures. The internal structure in buried hills can be reliably interpreted now and acquired two oil bearing traps are identical with drilling results after examination.
