摘　　要：对水平井和大位移井进行压裂,投资大,技术难度大。为使整个压裂经济有效,要有必对压裂后的产能进行预测。建立裂缝-油藏三维两相渗流模型及数值差分方程,将大位移井穿越的各产层作为一个整体考虑,采用数值模拟方法可以预测水平井和大位移井压裂后的产能。The investment is high and technical difficult is big when conducting fracture in horizontal and big displacement well. For effective whole fracture, it is necessary to do prediction after well fractured. The paper establishes a percolation model with three dimensions and two phases of crack and reservoir and a equation of numerical difference which makes every produced layer through by big displacement well as a whole integer to forecast postfrac production potential in horizontal and big displacement well.
