90年代，中国天然气勘探开发取得了巨大的成果。章对1990－2000年间中国21个含油气盆地储产量进行了详细统计，分析我国天然气储产量变化趋势。10年间天然气新增探明地质储量主要分布在中部区和西部区，分别占全国同期新增储量的43．58％和36．29％；其次为海域区和东部区，分别占13．08％和7．04％。截止2000年底，天然气剩余可采储量主要分布在中部区和西部区，分别占38％和36％，其次为海域区和东部区，分别占17％和9％。就单个盆地而言，天然气储量在90年代增长最多的前10位盆地依次为塔里木，鄂尔多斯，四川，莺歌海，柴达木，渤海湾，东海陆架，松辽，准噶尔和吐哈盆地。天然气无论在累计探明地质储量，还是在剩余可采储量均呈快速增长的趋势，但由于受到下游市场和天然气管道等因素的影响，天然气的产量增长相对缓慢，严重地制约了中国天然气工业的发展。中国目前油气工业的发展现状可概括为：石油后备资源严重不足，天然气管网和下游市场有待全力发展。90年代中国发现的天然气具有如下特点：（1）大型盆地新增探明地质储量构成90年代我国新增油气地质储量的主体；（2）地层岩性型圈闭类型明显增加；（3）海域和前陆盆地获油气重大突破的比例增大。

Analysis of China Natural Gas Reserve-production Change Trend in the Nineties

??In the 1990's,great achievements has been made in natural gas exploration and development in China.The detail statistics of the reserves and production rates in 21 oil-and gas-bearing basins from 1990 to 2000 are carried out and the natural gas reverse-production change trend is analyzed in the paper.The new-increased proved gas reserves in place during the ten years were mainly distributed in the central and west regions where they accounted for 43.58 percent and 36.29 percent of the total new-increased reserves in the whole country during the same time respectively,then the offshore and east regions where they made up 13.08 percent and 7.04 percent of the total ones respectively.By the end of 2000,the residual recoverable gas reserves were mainly distributed in the central and west regions where they amounted to 38 percent and 36 percent of the total residual recoverable gas reserves in the whole country respectively,then the offshore and east regions where they accounted for 17 percent and 9 percent of the total ones respectively.In regard to the single basin,the first ten basins of the growth of gas reserves in the 1990's were Talimu,E'erduosi,Sichuan,Yinggehai,Chaidamu,Bohaiwan,Donghai,Songliao,Zhunge'er and Tuha Basins.Not only the accumulative proved gas reserves in place but also the residual recoverable gas reserves were of the trend of rapid growth,but the increase in gas production was relatively slow because of the influence of these factors as market and gas pipeline,etc.,which restricts seriously the expansion of natural gas industry in China.The present situation of petroleum industry in China can be summarized as follows:serious shortage of reserve oil resources and need for fully expanding the natural gas pipeline and market.The natural gas discovered in China in the 1990's was of the following characteristics;?? the new-increased proved reserves in place found in large-sized basins constituted the main body of the new-increased petroleum reserves in place in China in the 1990's;?? lithostratigraphic traps increased evidently;and ?? the proportion of the important breakthrough in oil and gas exploration in offshore and foreland basins mutiplied.
