摘　　要：截至2005年底,中国已发现气田223个,探明天然气储量49536.6×108m3,年产气499.55×108m3。截止到2005年底,我国天然气探明储量和产量分别是1949年的12867倍和4541倍,近期中国天然气工业得到了迅速发展。中国天然气地学理论新进展主要有二:其一,中国近期发现昌德和兴城一批无机成因烃类气藏,使指导天然气勘探的理论真正进入了“多元论”阶段;其二,在珠江口盆地白云凹陷荔湾构造初步发现了储量逾千亿立方米的大气田。Up till the end of 2005, 223 gas fields had been discovered in China, with the explored gas reserves of 4953.6 billion m^3 and the annual gas production of 49.955 billion m^3, which were 12867 times and 4541 times respectively of those in 1949. The newest achievement in geoscientific theories on natural gas in China has been made in these two fields as follows: one is that several abiogenic alkane reservoirs have been found lately in Changde and Xingcheng areas, which pushes the geoscientific theory to be in 'pluralism' stage to guide gas exploration; another one is that a giant gas field with reserves of over 100 billion m^3 has been preliminarily discovered in the Liwan structure of Baiyun depression in the Zhujiangkou Basin.
