Abstract:According to the important effects of gas-water relative permeability of coal and rock in the field of coalbed methane develop-ment geology,based on systematic literatures review,methods of gas-water relative permeability of coal and rock determination,the re-search progress both at home and abroad,influencing factors and experimental conditions were summarized and analyzed in this paper.In view of limitations in various methods and hysteretic research status,the influencing factors and restricting experimental conditions for gas-water relative permeability of coal and rock were pointed out.Besides,some important directions for further studies of gas-water relative permeability of coal and rock were proposed aiming at providing reference information for coalbed methane effective development in future.
