Abstract

Permeability is important in evaluating coal reservoir, and the acquiring methods are various. In this paper, four main methods, i.e., drill stem test (DST), diagnostic fracture injection test (DFIT), production data analysis, and simulation were introduced. Though the hypothesis condition and application limitation are different, generally speaking, the first three methods should be adopted in the single-phase flow condition, and the fourth should be used in two-phase flow condition. Since an accurate permeability is difficult to acquire, the uncertainty range should be presented when analyzing permeability, and the determining method was also discussed.
