致密油藏强毛管力约束条件下多相渗流规律
An analytical model for multiphase flow in tight oil reservoirs under strong capillary force constraints
摘要
Abstract
This paper presents an analytical solution for spontaneous and forced imbibition in porous media and proposes the corresponding simplified algorithm.The solving method employs Laplace transforms and successfully addresses typical nonlinear partial differential equations.Finally,after comparing with the numerical solutions computed by fully implicit finite difference method,the feasi-bility and accuracy of this method in one-dimensional two-phase flow is proved.An analytical model is developed in this study,which solves dynamic flow rate and saturation of biphasic fluid flow in porous media with non-negligible capillary forces,such as tight oil reservoirs.The proposed method can quantify fluid flow in porous media with significant capillary forces that is unable to be solved by Buck-ley-Leverett approach.关键词
