有效孔隙度利用测井资料进行解释,解释基础是怀利公式,利用钻井取心资料与对应储层的电性参数统计回归,建立孔隙度解释模型。为提高测井解释孔隙度的精度。应首先对岩心进行归位,即将岩心深度和测井深度匹配,已避免造成深度误差,这是建立孔隙度图版的基础。孔隙度求取后,利用主因子分析根据孔隙度和渗透率回归关系建立渗透率解释数学模型[3]。
The effective porosity is explained by well logging data. The explanation is based on the Wiley formula. The porosity interpretation model is established by statistical regression of the drilling coring data and the corresponding reservoir electrical parameters. To improve logging accuracy of interpretation of porosity. The core should first be indexed by matching the depth of the core to the depth of the well, avoiding depth errors, which is the basis for creating a plate for porosity. After calculating the porosity, the mathematical model of permeability is established by principal factor analysis based on the regression relationship between porosity and permeability [3].
