摘要
FIELD: physics; geophysics.;SUBSTANCE: invention relates to geophysics. The method comprises determining fracture porosity and calculating resistivity at different depths of the fractured reservoir based on full diameter core data and imaging logging data; creating a percolation network model of matrix and fracture combination with known pore structure features; calibrating the numerical simulation results according to the percolation network model based on the data of a core experiment and sealed core analysis results, then obtaining the relationship between the resistivity (I) and water saturation (Sw) at different fracture porosity; calculating hydrocarbon saturation of the fractured reservoir by selecting an interpolation function.;EFFECT: high accuracy.;10 cl, 3 dwg
