Abstract: According to the fluid flow character of the fractured-porous reservoir, there is the fluid exchange between the frac-ture and matrix. The fluid flow among the fluids was not con-sidered in fracture reservoir in the past, and only the source and sink was considered in the fluid exchange between the fracture and matrix. The paper established the fluid flow different equa-tion of the full coupled fracture-porosity reservoir in term of the fluid flow between the fracture and matrix, the paper presented the Laplace transform solution in the Laplace space by the prin-ciple of the superposition. It has an important guidance meaning to understand the fluid flow law of the fracture-porosity reser-voir and well testing analysis.

Key words: fracture reservoir, coupled model, well test-ing analysis, different equation
