摘要: 以WarrenRoot模型为基础,引入分形参数和压缩系数,考虑了压力对具有分形特征的渗透率和孔隙度的影响,验证了变形双重介质分形油藏非线性渗流数学模型。利用离散泛函分析方法,引入不动点原理,就该模型一般形式的差分方程探讨了其解的存在性。研究认为:分形几何理论及方法在正确认识复杂非均质油藏及应力敏感地层油气藏方面具有独到优势。

Abstract: The nonlinear flow through porous media mathematic model of deformed dual media fractal reservoir, based on WarrenRoot model and the introduction of fractal parameters and compression coefficient, takes the influence of pressure on permeability and porosity with fractal feature into consideration. The existence of the solution of the differential equation of the model is probed according to discrete functional analysis and the fixed point theory. It is indicated that in correctly recognizing the complex heterogeneous oil reservoirs and stresssensitive formation oilgas reservoirs, fractal geometrical theory and the method are of unique advantage.
