【Abstract】 Enhanced oil recovery method in low permeability gas reservoir was summarized through investigation and research, which included six methods of optimizing pattern configuration and fracturing technique, technique of high and low pressure transportation separately, improving gas production technique, drilling special wells, seismic vibration method, and electroosmosis method. Based on the above mentioned, the existing questions were put forward and solving methods were given. At the same time, the future developing trend and direction of enhancing oil recovery in low permeability gas reservoir were expounded. It will be meaningful for development and enhancing oil recovery of this kind of gas reservoir.更多还原
