| 摘 要： | 大港千米桥潜山目的层埋藏深,速度横向变化大,地下地质情况复杂。叠后、叠前时间偏移地震资料不能满足地质需求。为此,采用了提高潜山成像精度的最有效手段,三维连片叠前深度偏移处理技术对该区进行重新处理。文中介绍了叠前道集精细处理、建立初始深度—速度模型、模型的优化、偏移与校正等技术与实现过程。新处理的叠前深度偏移地震资料与旧资料对比,不仅成像精度高,而且得到的波动信息更加丰富。应用新资料重新评价千米桥潜山气藏,取得了一些新认识和显著的地质效果。

| Abstract: | The objective interval of Qianmiqiao buried hill has buried deep,big lateral variation of velocity and the complex underground geological conditions.The post-stack and pre-stack time migration seismic data can not meet the geological demands.For this reason,the most effective method is adopted for re-treatment contiguous three-dimensional pre-stack depth migration processing technology in the area to improve imaging precision in Dagang buried hill.This paper introduced some technique and the realization pro... |
