摘　　要：多期沉积储层会形成曲流河、辫状河、三角洲等不同砂体构型模式,不同砂体叠置关系及内部构型特征使水淹规律、水驱开发效果多解性强。精细立体开展水驱效果评价成为制约老油田剩余油有效挖潜的主要因素。在充分利用井间示踪剂资料、油水井生产数据分析注采对应关系的基础上,结合区域井间砂体连通关系明确水驱优势方向,分析水驱连通层位,从见效时间、平面、纵向三个维度深入剖析水驱规律,基于多资料开展水平井砂体构型刻画,明确剩余油富集层位,采取挖潜措施,使停产老井X10-H2井日产液9 t,日产油2.32 t。研究证明动静结合多维度综合评价薄互储层水驱效果措施有效率提升了10%。该方法为老油田“压舱石工程”提供了可靠的技术支撑和示范模板。It is difficult to evaluate the water flooding effect of multi-stage superimposed reservoir,and the law of water flooding is not well understood,which become the main reasons restricting the effective exploitation of remaining oil in old oilfield.In this paper,on the basis of making full use of interwell tracer data and oil-well production data to analyze the corresponding relationship between injection and production,the dominant direction of water drive is defined according to the connectivity relationship between wells and sand bodies,and the connected horizon of water drive is analyzed.The law of water drive is analyzed from three dimensions:response time,plane and vertical.Based on multiple data,the sand body configuration of horizontal wells was described,the remaining oil enrichment horizon was defined,and suggestions on potential exploitation measures were put forward successively to help X10-H2 well produce 9 tons of fluid per day and 2.32 tons of oil per day,so that the discontinued old well could gain“new life”.It is proved that the method of multi-dimensional comprehensive evaluation of thin interreservoir water flooding effect combined with dynamic and dynamic can make the results more accurate,reasonable and reliable,and the measure efficiency can be increased by 10%.This method provides a reliable technical support and demonstration template for“ballast stone engineering”in old oil fields.
