【摘要】 储层大孔道的存在对油田注水开发有着重要的影响。要改善高含水期油藏注水开发效果,实现稳油控水,提高水驱效率,就必须加强对储层大孔道的识别。在研究大量中外相关文献资料的基础上,系统地概述了现有储层大孔道识别方法,分析了当前识别方法各自的优越性及存在的问题,并根据现代油藏描述发展要求提出了全新的储层大孔道识别构想——颗粒示踪技术。该技术把固体颗粒作为对储层孔道大小进行测量和描述的载体,可以实现对储层非均质性描述由定性向定量的飞跃。准确地识别储层大孔道,可为油田后续增产措施的优化设计提供依据,利于提高原油采收率和油田开发效益。更多还原

【Abstract】 It has significant influence to oilfield waterflood development of high capacity channel of reservoirs.In order to improve waterflood results including stabilizing oil production,controlling water cut,and enhancing waterflood efficiency during high water cut stage,identifying high capacity channels of the reservoirs must be reinforced.Based on research on mass relative documents home and abroad,the current identification methods of the high capacity channel were summarized,and advantages and disadvantages of these methods were analyzed.A new identification design of the high capacity channel was raised based on the development requirement of contemporary reservoir description that named particle tracer technology.It makes particle as carrier,which measures and describes reservoir channels,and describes reservoir heterogeneity from qualification to quantification.Identifying the high capacity channel of the reservoirs accurately provides a criterion for optimization design of following stimulation treatment,and has important practical significance to enhance crude oil recovery and oilfield development benefits.更多还原
