摘要/Abstract

摘要： 20世纪70年代，国家的能源供给主要是煤炭和石油，作为重要能源的天然气仍被大多数人所忽视，当时盛行的“一元论”油型气理论认为产煤地区是不可能产生天然气的。1978年，中国学者首次提出煤成气概念，此后40年，中国煤成气理论经历了引进、吸收、创新、发展、形成体系、指导天然气工业生产快速发展的全过程，其理论内涵包括气源鉴别指标体系、煤成气成藏机制与分布规律、评价预测技术方法等，应用中国煤成气理论先后准确预测了5个亿级以上大气田，使中国的煤成气占天然气比重从不足10%提高到67%，推动了中国天然气产量和储量的快速增长，为中国天然气工业快速发展做出重大基础性贡献，具有重要战略意义。

Abstract: In the 1970s, China's energy supply was mainly coal and oil. Natural gas, an important source of energy, was still ignored by most people at that time. The prevailing "monism" theory of oil-derived gas then held that coal-producing areas wouldn't produce natural gas. However, Chinese scholars first put forward the concept of coal-derived gas in 1978. In the next 40 years, the coal-derived gas geological theory in China has gone through the whole process of introducing, absorbing, innovating, developing, forming system and guiding the rapid development of natural gas industry. Its contents include the index system of gas source identification, the accumulation mechanism and distribution law, and the evaluation and prediction technique of coal-derived gas, etc. The application of the theory has accurately predicted more than five large gas fields of over 100 million m³ magnitude, making the proportion of coal-derived gas in natural gas of China soar from 10% to 67%, and propelling the rapid growth of natural gas reserves and production in China. Apparently, the theory has important strategic significance to Chinese natural gas industry and has made fundamental contribution to the fast development of gas industry in China.

Key words: natural gas, coal-derived gas, coal-derived gas geolgical theory, monism, dualism, strategic
