摘要
根据分形几何学并结合非达西渗流力学 ,建立了分形油藏低速非达西渗流的数学模型。根据拉氏变换和Stehfest数值反演求得了有限半径井的实空间解 ,并分析了分形参数、非达西渗流指数等对压力动态的影响。研究分形油藏非达西低速不稳定渗流的动态特征 ,对低渗透油田的开发具有指导意义。
Numerical model of low velocity non Darcy percolation for fractal reservoir has been set up according to fractal geometry and non Darcy percolation mechanics. Real space of finite radius well has been deduced from Laplace transform and Stehfest numerical inversion. Influence of fractal parameter and non Darcy percolation index on pressure behavior is also analyzed in this paper. Research of non Darcy, low velocity, unstable percolation in fractal reservoir may guide the development of low permeability reservoirs.
