本文按照双水法模型,根据一口井的测井资料建立本井的100％含水地层的多元线性回归方程,然后把该井的测井资料代入所建立的多元线性回归方程,作出100％含水地层电阻率曲线。把这一计算的曲线与实测的探测电阻率曲线进行重迭比较,检出油气层,并计算出粘土水的含水饱和度、单位地层体积中自由水的含量及单位冲洗带地层中的自由水的含量。 According to the double water method model, a multiple linear regression equation of 100% water-bearing strata of the well is established based on well logging data of one well. Then the well log data is substituted into the established multiple linear regression equation to make a 100% Resistivity curve. Comparing this calculated curve with the measured resistivity curve, the hydrocarbon reservoir was detected and the water saturation of clay water, the free water content per unit volume and the free water in the unit wash zone were calculated Content.
