| Abstract: | Water blockage is a ubiquitous problem during the development of low permeability gas reservoirs. In order to improve the gas effective permeability of low-permeability gas reservoirs, alcohol has been used in controlling water blockage. Based on the indoor experiments, the mechanism of alcohol treatment has been studied and the application effect of several alcohol solutions has been evaluated and compared. Result shows that damage caused by water blockage in low permeability gas reservoirs can be effectively retarded by the alcohol treatment. |
