摘 要:低渗透砂砾岩体储层的油水关系比较复杂,有效储层的判识难度大。因此,在常规以孔隙度、渗透率等物性下限进行有效厚度判识方法中,加入含油饱和度下限标准有助于更准确的判识砂砾岩体有效储层。在借鉴前人研究方法基础上,充分应用渤南油田某地区岩相、试油、试采资料,相渗等资料,应用孔隙度与含油饱和度图版法、相渗曲线法等两种不同方法对渤南油田某地区低渗透砂砾岩体储层含油饱和度下限值进行了计算,计算结果表明,二者结果接近。说明这两种方法对于低渗透砂砾岩体储层含油饱和度下限值计算是可行的。The relationship between oil and water in low permeability glutenite reservoir is complex,and the effective reservoir recognition is difficulty.So, effective thickness identifica- tion method for porosity,permeability physical limit,add oil saturation limit standards con- tribute to more accurate identification of glutenite reservoir.On the basis of previous research methods,full application of Bonan oilfield area facies,oil test,production data,the relative per- meability data,application of porosity and oil saturation,relative permeability curve chart method by two different methods, region of Bonan oilfield low permeability glutenite reservoir oil saturation limit values were calculated,close to the calculation results of two.The two method calculation is feasible for low permeability glutenite reservoir oil saturation limit.ln addition,Established the different water production rate of oil production and containing liq- uid production chart of the low permeability giutenite reservoirs in Bonan oilfield,providing a new method for the fast calculation of different water production rate of oil saturation.
