Abstract: In this paper, the well-testing analysis is made, based on the finite element method, for a naturally fractured reservoir with two intersection boundaries. Covergence of the numerical solution is proved and some typical theoretical curves of the pressure are presented in the cases of different location of the well position, different types of boundary conditions, and different intersection angles of the boundaries.

Key words: aturally fractured reservoir, finite element method, convergence
