摘要/Abstract

摘要： 考虑与实际生产相符的介质的双重特性和分形特征,并考虑介质的变形,引入双重分形介质渗透率模数,建立应力敏感地层双重分形介质系统的流动方程.采用Douglas-Jones预估-校正法获得无限大地层定产量生产时变形双重分形介质模型的数值解和无限大地层定压生产时分形介质双孔模型的数值解,作出了典型的压力曲线图版.

关键词: Douglas-Jones预估-校正法, 低渗油藏, 变形双重介质, 分形油藏

Abstract: We establish a flow equation stress_sensitive to permeability for fractal and deformed double porous media and introduce permeability modulus of double porous media fractal reservoir.Numerical calculation in a fractal double porous media model with constant rate production or constant pressure production in an infinitely large system is carried out with the Douglas_Jones predictor_corrector method.Typical pressure curves are shown.

Key words: Douglas-Jones predictor-corrector method, low permeability reservoir, double porous media, fractal reservoir
