Abstract: In this paper ,we have systemically presented the Laplacespace solution to bottomhole pressure distribution in complexreservoir with three kinds of outer boundary conditions (infinite uter boundary , closed boundary , constant pressure) and two er boundary conditions (wellbore storage and skin effects) ,and the relationship between the solutions are also analyzed
completely , and then a general formula is derived. This simpleand practical general formula provides fundamental theory forwellOt est analysis and has great superiority and practicability in programming applications.

Key words: complex reservoir, boundary conditions, bottomhole pressure, Laplace space solution, general formula
