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 ,经核对与钻井结果十分吻合
The buried hill in Puxi has undergone a long-term and complex geological evolution process, forming a complex underground structure and a sudden change of velocity. It is difficult to obtain geological information of buried hill by conventional time migration data. In this paper, parallel processing is done by using the domestic 3D prestack depth migration parallel software. The migration results are accurate and the geological images are obviously improved. Which can reasonably explain the internal structure of the buried hill and obtain two favorable oil-bearing traps, which are in good agreement with the drilling results
