Abstract:

In view of constant pressure outside boundary double permeability composite oil reservoir model, the variable rate question dimensionless pressure distribution Laplace solution has been studied, and the corresponding application briefly derived. The research perfects well testing theory, it has the profound application value to well test analysis software development, also has the guiding sense to the oil reservoir numerical simulation method.

Key words: doublepermeability composite oil reservoir, constant pressure outside boundary, pressure distribution, variable rate, Laplace solution
