摘要

According to the influence of internal agency, the boundary of actual reservoir is complex. In this paper, by the fluid flow theory through porous media, the authors establish the mathematic model of partly perforation 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, the authors resolve it and obtain the boundary element basic solution. The authors establish the pressure response model of partly perforation well in complex boundary reservoir. The dimensionless pressure and pressure derivate double log type curve are obtain by calculating the pressure response function, and analyzing the characters of fluid flow through porous media and its influence effects.
