摘要: 针对注水开发油田不同程度的水淹, 以往利用测井解释的含油饱和度曲线建立的含油饱和度模型, 不能满足油田开发需求。为了在模型中更真实地反映出地层的原始含油状态, 首先把油藏条件下的毛管压力曲线 转换成J 函数, 再利用多元回归得到J 函数与含水饱和度间的关系, 最后把由油水界面和储层构造深度计算得到油 柱高度, 经多元回归建立含油饱和度与孔隙度、 渗透率和油柱高度的关系式, 进而得到三维含油饱和度场, 从而为储 量复算和油藏数值模拟提供准确依据。

Abstract: In view of the different flooding degree of waterflooding oil field, the oil saturation model established with oil saturation curve from logging interpretation in the past can’t meet the demand of oilfield development. In order to reflect the original oilbearing state of strata more truly, the capillary pressure of reservoir is converted into J function firstly. And then we get the relationship between J function and water saturation with multiple regression. Finally, via multiple regression, we establish the relation between oil saturation and porosity, permeability and oil column height calculated with oilwater interface and reservoir structure depth, and thus obtain threedimensional oil saturation field, which provide accurate basis for reserves recalculation and reservoir numerical simulation.
