煤成气研究促进中国天然气储量迅速增加

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 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。

The research of coal-formed gas accelerating the increase of natural gas reserves in China

The prompt increase of the natural gas reserves in China in the recent years is mainly contributed by the successful exploration of coal-formed gas. From the Natural Gas Science and Technology Research Project in the beginning of 1980s, over 69% of new-proved gas reserve is coal-formed gas. By the end of 2000, 78.9% of the proved reserves of the large and medium gas fields (with proved gas-in-place over 100×108m3 in each) is coal-formed gas, all the four largest gas fields in China are coal-formed gas fields. The research on coal-formed gas geological theory, achievements in the State Science and Technology Research Project during the past 20 years, widened the exploration target area, brought about the prompt increase of coal-formed gas reserves.
