Because of achieved coalbed methane production and CO(2) emission reduction, technologies on CO(2) injection to enhanced coalbed methane recovery in coal reservoirs (abbreviated as CO(2)-ECBM)can become a concern of one of the ways of green carbon. In this paper, the impact of key factors that promote the use of CO(2)-ECBM was discussed, and the key technologies needed further refinement and development in indoor simulation, engineering experiments, and industrial application were investigated. The results were for the early realization of the win-win goal that CO(2) sequestration and enhanced Coalbed Methane Recovery in Coal Reservoirs in China.
