【摘要】 胜利油区的主要探区已基本为三维地震资料所覆盖,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。本文系统地分析了胜利桩海地区三维地震资料大连片处理的地质效果,认为其具有资料信噪比高、分辨率高、拼接自然,所反映区域构造合理、断裂系统清晰、超覆与尖灭等地质现象清楚等优点。连片处理资料消除了区块边界效应,有利于构造整体评价,有利于区域沉积相的系统研究,并可节省大量再次采集资金。更多还原

【Abstract】 3D seismic data have been acquired in the main prospecting area in Shengli oil region, but most of them werefrom small 3D blocks over the years. It could be unfavorable to evaluate and recognize entirely the area. This papersystematically analyzes the geologic effect of the processed 3D merging seismic data in Zhuanghai area, Shengli Oil-field, and considers that the data have many advantages, such as high signal-to-noise ratio, high resolution, naturalmerging, which also gives out reasonable structure , clear fault system an clear lapout and pinch out etc in the area. Themerging data processing removed the boundary effect between blocks, beneficial to evaluate entirely the structuresand research systematically the regional sedimentary facies, which saved much cost for reacquisition.更多还原
