摘要: 特低渗油田在开发中后期,注水效果的评价对开发调整极其重要,地层存水率和水驱指数与特低渗透油田的注水效果究竟有什么样的关系?以安塞油田H区块为例,通过对地层存水率和水驱指数两项指标的曲线绘制及研究分析,评价了安塞油田H区块的注水开发效果,并利用室内实验以及油田动态资料进行验证。研究认为在特低渗透油田注水开发过程中,实际存水率、水驱指数曲线落在标准曲线之间,油田注水开发效果理想;落在标准曲线之上或之下,注水量偏大或偏小,注水开发效果不理想。存水率、水驱指数对特低渗油田的注水开发效果起到了客观准确的评价作用。

Abstract: In the mid-late period of production in ultra-low permeability reservoirs,the evaluation of water injection is very important to development adjustment.What is the relationship among formation water storage rate,water flooding index and the water injection effect in ultra-low permeability reservoirs? H block of Ansai Oilfield is taken as example,by means of the curve plotting and analysis of formation water storage rate and water flooding index,the effect of development by water flooding to the block is evaluated,and the result is verified by using in-door experiment and in-situ dynamic data.It is recognized in the process of development by water injection of ultra-low permeability reservoirs,if the actual water storage rate and water flooding index curves are located between the standard curves,the effect of development by water injection is the best,and if they are above or below the standard curves,the effect is not so good.Water storage rate and water flooding index play an objective and correct evaluation role to the effect of development by water injection in ultra-low permeability reservoirs.

Key words: ultra-low permeability, water storage rate, waterflooding index, waterflooding, geological reserves, Ansai Oilfield
