| Abstract: | On the basis of analysis on the rules of percolation of non-flow well in drill stem test (DST) of reservoirs with actual low velocity and non-Darcy double porous medium, a mathematical model of its effective well diameter is derived, Laplace inversion and the theory of special physical equations are used to derive the Laplace special analytical equations, and the simplified Stehfest algorithm is used to conduct a numerical inversion for obtaining a actual special solution, and dimensionless type-curves are drawn, which can be used effectively for field analysis of DST slug flow well testing. |
