近年来我国天然气探明储量明显增长,主要得益于煤成气田的成功勘探。1980年以来,新增天然气探明储量的69％是煤成气;煤成大中型气田的探明储量占全部大中型气田储量的78.9％;我国最大的4个气田均为煤成气田。煤成气储量迅速增长的一个重要原因在于煤成气理论研究。煤成气理论大大拓宽了勘探领域,而国家组织的多年连续的科技攻关促进了这一理论的发展。目前中国煤成气勘探依然大有潜力,有目的地勘探煤成气将继续取得明显效果。图2表1参13（夏新宇摘） In recent years, the proven reserves of natural gas in our country have obviously increased, mainly due to the successful exploration of coal gas fields. Since 1980, 69% of newly-added proven natural gas reserves have been coal-to-gas; the proven reserves of large and medium-sized coal-fired gas fields account for 78.9% of the total reserves of large and medium-sized gas fields; and the four largest gas fields in China are coal-based gas fields. An important reason for the rapid growth of coal-to-gas reserves lies in the theory of coal-to-gas. The coal-to-gas theory has greatly broadened the field of exploration, and many years of continuous scientific and technological research conducted by national organizations have promoted the development of this theory. At present, China’s coal-to-gas exploration still has great potential and the targeted exploration of coal-to-coal gas will continue to achieve significant results.
