Production Prediction Model of Fractured Sandstone Gas Reservoir and Sensitivity Analysis

Abstract:

According to the fractured sandstone gas reservoir seepage characteristics and well test theory, mathematic model and numerical model of homogeneous formation fractured sandstone reservoirs were established. Using Laplace transform to solve the model, and analyzed the sensitivity of parameters of affecting fractured sandstone gas reservoir productivity prediction curve. The result shows that the number of branch and half-length of cracks, the ratio of coefficients of pressure derivative and fracture conductivity have significant effects on gas well early productivity; the increase of the skin factor can reduce production. It provides beneficial suggestions to improve the productivity of fractured sandstone gas reservoir.
