【Abstract】 The method of orthogonal transformation and the theory of matrix differential equation are used in this paper to obtain the precise point source solution for the transient flow in a naturally fractured reservoir that is infinite in all directions, and by the application of this precise solution, a number of precise solutions can be further obtained for mathematical model of well test analysis.更多还原
