Abstract

Abstract: Based on the low-velocity non-darcy fluid flowtheory in porou media of Non-Open flowwells in composite reservoirs, the effective wellbore radial model of this kind ofwell testwas derived, the solution of this model was gotten in Laplace space with Laplace transfor mation and special physical equations theory, then the real space solution was gotten by convenient Stehfest’s numerical Laplace revers transformation. The new type curve of the model was also obtained.The model described in this paper can be used for slug well tes
analysis in low permeability reservoirs.

Key words: Non-Darcy flow, composite reservoirs, slug flow, DSTwell test, mathematical model, gradient of kick-off pressure
