【摘要】 近年来 ,我国天然气可采储量和产量都在迅速增长。截至 2 0 0 2年底 ,全国总计探明天然气可采储量为 2 .2 6× 10 1 2 m3,剩余可采储量为 1.86× 10 1 2 m3,储采比为 5 7;天然气年产量为 32 6× 10 8m3,比上年增长 8.2 9% ;天然气输气管道建设也如火如荼。文章提出要通过采取加强对国内低渗透、特低渗透天然气和煤层气的勘探与开发 ,进口境外管道天然气和LNG ,加快天然气管网等基础设施建设和对下游天然气市场的培育 ,引导和协调天然气消费等措施来满足我国对天然气日益增长的需求。最后还指出 ,鉴于中国是产煤大国且国内能源仍以煤为主的现实 ,天然气在未来的一次能源消费结构中的比例以 8%～ 12 %较为合理。更多还原

【Abstract】 The achievements of investigating natural gas by three large petroleum corporations.i.e.CNPC,Sinopec and CNOOC of China in recent years are introduced in the paper.By the end of 2002,through the whole nation statistics,proved recoverable gas reserves was 2.26×10 12 m 3,remaining recoverable gas reserves 1.86×10 12 m 3 and reserve-production ratio 57;annual gas production was 32.6×10 9m 3,which had increased by 8.29% as compared with that of last year;and gas pipeline construction was on a grand and spectacular scale.In order to meet the increasing needs for natural gas in China,it is pointed out in the paper that these measures must be taken,such as strengthening the exploration and development of the natural gas in low and extra-low permeability reservoirs and of the coalbed methane;importing offshore pipeline gas and/or LNG;quickening the infrastructural construction of gas pipe network,etc,and the cultivation of downstream gas markets;and guiding and coordinating natural gas consumption,etc.Finally,it is also pointed out that in the future,the reasonable proportion of natural gas in primary energy consumption structure will be 8%—12% in China in view of that China is a major coal-producing country and of the reality of coal’s being mainly consumed in domestic energy structure.更多还原
