摘要: 压裂作为低渗油气藏开发和油田增产的措施之一,被油田广泛应用.为使压裂方案经济合理,达到少投入多产出的目的,并提高压裂设计水平,我们对油气藏定压生产条件下压裂井产量预测的数学模型进行了数值求解,指出了各种模型的适用条件和要考虑的因素.本文主要介绍区域有裂缝存在、系数还依赖未知函数的非线性抛物型油气藏方程的数值求解。

Abstract: The hydraulic fracturing are widely used in oil field as a good means of the exploit of low permeability oilgas reservoir and the output increase of oil field. To make the hydraulic fracturing scheme economic, reasonable, and improved, a numerical solution is given to the mathematic model of predicting the hydraulic fracturing oil's output on condition of constant wellbored Pressure production of oil-gas reservoir. The various conditions and elements needed to be considered for the model are described. It provides an overview on the numerical solution of nonlinear parabolic oil-gas reservoir equations with the fracture in the area and the coefficient depending on the unknown function.

Key words: oil-gas reservoir, hydraulic fracturing, numerical simulation
