Model of DST slug well test for low velocity non-Darcy flow in layered reservoirs. (Chinese. English summary) Zbl 1171.86352

Based on the analysis of the realistic fluid flow in the double-permeability reservoirs at low velocity and non-self open flow situation during DST test, the mathematical model of effective well bore radius about the physical phenomenon has been derived in this paper. Using Laplace transformation method and special physical equation theories, the analytical solution of this model in Laplace space has been gotten. In order do get real space solution, authors used Stehfest’s numerical Laplace transformation method. This model and analysis method can be used for DST slug well test in oil fields.
