摘　　要：胜利油田主要探区已基本实现三维地震资料覆盖,但多为历年积累的小区块三维,不利于探区的整体评价和认识,因此在胜利油田桩海地区进行了三维地震资料大连片处理。处理后的三维连片资料不仅消除了区块边界效应,而且提高了资料的品质,资料的信噪比和分辨率都比较高,反映区域构造合理,断裂系统较清晰,超覆与尖灭等地质现象清楚。利用三维连片资料取得了新的地质认识,通过整体评价,部署了新的探井,获得了高产油气流。对连片三维资料的综合研究,取得了很好的地质效果,新发现落实了一批圈闭,并设计了多口探井井位。3-D seismic data have been acquired in the main prospecting area at the Shengli oil region, but most of them were from small 3-D blocks over the years. It could be unfavorable to evaluate and recognize entirely the area. This paper analyzes systematically the geologic effect of the processed 3-D a piece from piece-together processing seismic data in Zhuanghai area, and considers that the data have many advantages, such as high signal-to-noise ratio, high resolution, natural merging, which also gives out reasonable structure, clear fault system an clear lapout and pinch out etc in the area. Data processing assembly removed the boundary effect between blocks, beneficial to evaluate entirely the structures and research systematically the regional sedimentary facies, whichsaved much cost for reacquisition.
