摘要
本文建立了分形油气藏非达西低速渗流时续流和表皮效应影响的数学模型,并对定解问题用拉普拉斯变换求解,拉氏空间的特解用格林函数表示,得到了解析解和渐近解。
In this paper, the influence of the after flow and skin effect for non-Darcy flow at low velocity through fractal reservoir is studied and a mathematical model is developed. The Laplace transform is used for mathematical model. The special solutions of Laplace space are expressed by the Green function, and then the Laplace inverse transform is used for their solutions. The early-time and late time limiting forms of the wellbore pressure solution are presented.
