ABSTRACT
A series of climate problems that are associated with global warming have been paid attention by worldwide nations and CCS technology (CO2 capture and storage) just appeared and developed under this background. It contains the storage of CO2 in saline formation, unminerable coal layer(CO2-ECBM), depleted oil field (CO2-EOR)and depleted gas field(CO2-EGR). Through the CCS technology, we not only can solve the emission problems of CO2, but also can produce commercial benefits which can outfit the cost of storage fees. Among them, CO2-EGR is a project that can produce economic benefits which is now studied by many research centers and oil or gas companies for the benefits of it comparing to saline formation and other technology, for example, the great storage potential capacity and safety features which can contain natural gas for millions of years, and besides, the CO2 can be used to displace the residual gas in the depleted gas reservoir by increasing the pressure of the reservoir, therefore more natural gas will be produced. The biggest challenge of CO2-EGR technology is the early breakthrough problems of CO2 in produced wells and the mixing reaction of CO2 and CH4 can also reduce the quality of the produced natural gas. From this point of view, the study on multi-component properties of CO2-CH4 is very important for the success of CO2-EGR technology. In this paper, the study on the processes of CO2-EGR technology will be carried out from several aspects, including the potential of CO2-EGR technology, the mixing properties of CO2-CH4 system and reservoir simulation(the impact of depleted reservoir pressure and injection rates of CO2 on CH4 recovery, CO2 breakthrough time, CO2 injection capacity and CO2 injection time).
