摘　　要：当前中国天然气工业呈现出良好的发展趋势:一是中国从贫气国正迈向产气大国,2 0 0 5年产气量将达近5 0 0×1 0 8m3 ;二是中国天然气勘探理论从一元论发展为多元论;三是天然气产量的提高要求强化天然气的勘探和开发。近2 0多年来,中国天然气地学理论取得重要进展:一是揭示了煤系成烃以成气为主成油为辅的规律;二是建立了可信度和准确性高的各类成因天然气的鉴别指标;三是确定了半定量和定量的大气田形成主控因素;四是认识到了碳酸盐岩有机碳含量在0 .2 %左右及其以下时难以作为烃源岩和在0 .5 %及其以上时可作为有效烃源岩;五是查明了无机成因气不仅存在并可成藏,在中国东部盆地发现了一批CO2 气田(藏) 。The gas industry in China shows excellent developing trends: firstly, from country poor in natural gas to the one rich in it. In 2005, the gas output has reached near 500×10~8 m^3; secondly, the theory of natural gas exploration develops from monism(oil type gas-generating theories) to dualism(oil-type and coal-formed gas-generating theories); thirdly, the increasing gas output calls for strengthening in natural gas exploration and development. During the past more than 20 years, the natural gas geological theories have developed much: The coal measure source rocks mainly generate gas with minor oil; the identification index with high credibility and accuracy on various natural gases have been set up; the studies on the controlling factors of great gas field formation, by quantification or semi-quantification; the carbonate with TOC content about or lower than 0.2% can hardly be regarded as sources rocks and the TOC content of effective carbonate source rocks must reaches or more than 0.5%. Not only the abiogenic gas exists in the nature, but also can it form gas pools. Several CO 2 gas pools have been found in eastern basins of China. And the first abiogenic alcane gas reservoir in the world has been demonstrated by natural gas geochemistry.
