The Stress Sensitivity Test for Dense Reservoir Rocks in Low Permeability Gas Pool

Abstract

Abstract: There exist big differences in studied result with different test methods for dense reservoir rock in low permeability gas pool is sensitive to the stress. In this paper, three different test methods are applied to five core samples from Daniudi gas pool, respectively, and their stress changes between the test results and real production performances are analyzed in detail. Finally, two of three methods are selected, which are better reflecting the stress sensitivity variation rules.

Key words: dense reservoir rock, low permeability, stress sensitivity, overburden pressure, fluid pressure
