///Under the present situation of abnormal energy structure in China with over dependence on coal and the developing trend of unconventional natural gas in the world, China has to put equal stress on the development of both conventional and unconventional natural gas resources to promote rapid progress in the natural gas industry. Therefore, with the purpose of promoting the progress of unconventional natural gas in China,this paper suggests that 1) more preferential policies be formulated on tight gas development and the involved techniques be promoted to reduce its lower economic limit; 2) the key techniques of CBM gas exploitation be completed to speed up its development; and 3) shale gas resources be evaluated in a reliable and all-around way, the pilot test zones be quickly constructed, and technical difficulties be tackled.
