Water Locking Mechanics Characteristics and Countermeasures of Low Permeability Gas Reservoir

Abstract:

The research goal of this paper is reducing damage of low permeability gas reservoir, utilizing the natural cores which from low permeability gas reservoir as ex-periment model, based on similarity theory conducting the fluid-structure interaction experiment of reservoir fluid and injection working fluid with cores, the experimental results show that the effect of gas well reservoir fluid and external fluid with cores, it is inevitable to produce water locking mechanical for the cores which from low permeability gas reservoir, and carry out the corresponding control measures experiment research, and put forward that add alcohol to injection fluid can inhibit water locking.
