摘要

兴隆台油田经过三十多年的开发之后已进入高含水后期,地下剩余油呈现"局部相对富集、整体高度分散"的状态,利用精细地层对比结果研究微构造类型及油水运动规律,分析不同微构造类型的剩余油分布特点,将是高含水油田进行调整挖潜的有效途径之一。综合运用精细地质分层、三维地震解释等技术,在剩余油富集的微构造区域部署高效调整井可以更有效地采出剩余油,提高挖潜效果。
Developed for more than thirty years,Xinglongtai Oilfield has entered into its mature stage with a high water cut. The distribution of remaining oil in mature reservoirs is characterized by high scattering in the whole field and relative abundance in some localities. Mini-structure types and oilwater movement rules are studied and the remaining oil distribution features of different mini-structure types are analyzed through the use of detained stratigraphic correlation results,which will be one of effective methods of adjusting and tapping potential in high water cut oilfields. The deployment of high-efficiency adjustment well can effectively produce the remaining oil in the mini-structure areas of remaining oil concentrated through the integrated use of fine geologic zonation and 3D seismics explanation techniques,which can improve the effect of potential tapping.
