| Abstract: | This paper analyzes the physicochemical properties of supercritical CO2, the characteristic of shale gas and shale gas reservoirs. The technologies of drilling,production, fracturing using the supercritical CO2 in shale gas exploration are proposed, to increase the penetration rate, decrease the damage to formation while fracturing, and enhance the recovery of shale gas. It is believed that the huge economic benefits of shale gas exploration with the supercritical CO2 fluid will be obtained, and it also can initiate a new technology field of CO2 in the petroleum engineering. |
