摘要
针对华北油田晋４５ 断块的测井系列、具体地质状况及岩性、物性资料， 建立了利用４ ｍ 电阻率相对值的水淹层解释模型。使用该模型确定水淹层含水饱和度、泥质含量、孔隙度， 束缚水饱和度、残余油饱和度、水相渗透率、油相渗透率、含水率和驱油效率等系数， 并给出水淹层划分标准。经对晋４５ 断块２０多口井的资料处理， 解释符合率达８５％ 以上。
A watered out zone interpretation model is set up where the relative resistivity of 4m in relation to logging series, lithological and physical information for the fault block Jin 45 in Huabei oilfield is used By means of the model, parameters on water saturation,shale index,porosity,irreducible water saturation,residual oil saturation,water phase permeability,oil relative permeability, water cut and oil displacement efficiency are determined, and a standard for dividing watered out zone is formulated The process of data from 20 wells of Jin 45 by this model demonstrates that the coincidence rate is more than 85 percent
