摘要

According to the influence of internal agency, the boundary of actual reservoir is complex.In this article, using the fluid flow through porous media theory, we establish the mathematic model of horizontal well in complex boundary reservoir.On the base of Lord Kelvin point-source solution, the integral of Bessel function, Poisson superimpose formula and boundary element method, we resolve it and obtain the boundary element basic solution.We establish the pressure response model of horizontal well in complex boundary reservoir.Obtain the dimensionless pressure and pressure derivate double log type curve by calculating the pressure response function.And analysis the character of fluid flow through porous media and its influence effect.
