中国天然气勘探开发60年的重大进展

Significant advancement in natural gas exploration and development in China during the past sixty years

通过对1949年到2009年60年来中国天然气探明储量和产量增长情况的分析,总结了煤成气理论的意义和勘探成就,梳理了大气田的勘探开发成果和意义。研究认为60年以来,中国天然气勘探开发取得了突破性进展:1)储量上从贫气国跃为世界前列国。1949年中国天然气探明地质储量只有3.85×108m3,2009年超过了7×1012m3。2)天然气年产量跃为世界第七。1949年中国天然气产量只有1117×104m3,2009年则达852×108m3。3)煤成气理论推进了中国天然气勘探开发的快速发展。1979年中国煤成气理论的出现,开辟了天然气勘探的一个新领域,使指导天然气勘探理论从"一元论"发展为"二元论"。4)勘探开发大气田是快速发展中国天然气工业的重要途径。至2009年底中国共发现44个大气田,大气田总储量占全国的80.5%,天然气年产量占全国的66.4%。60年间中国天然气的勘探开发取得了重大成就。

Based on analyzing the reserve and production growth of natural gas in China from 1949 to 2009,we summarize theoretical and practical significances of the coal-derived gas theory and sum up the achievements in exploration and development of giant gas fields and their significances.Over the past sixty years,significant advancement has been made in gas exploration and production in China.First,China has become one of the world’s top players in natural gas reserves.In 1949,China’s proved geological reserves was only 0.385BCM,but in 2009,this number exceeded 7 000BCM.Second,with a annual production of 85.2BCM in 2009,China is the world’s 7th biggest gas producer now,while it only produced 11.17MCM of gas in 1949.Third,the theory on coal-derived gas has promoted the rapid advancement of gas exploration and production.In 1979,the theory on coal-derived gas emerged as a new theory to lead the exploration and production of natural gas.Fourth,it is an important way to rapidly development China’s natural gas industry by exploring and developing giant gas fields.By 2009,44 large and giant gas fields have been discovered in China.They account for 80.5% of the total reserves and 66.4% of total gas production in China.Significant progress has been made in natural gas exploration and development in China during the past sixty years.
