摘要
我国气源岩分布面积广,煤系地层多,可形成丰富的和多种类型的天然气及其气藏,已发现的气藏可划分为4大类12亚类。但是,目前我国天然气探明程度仅有百分之几,已发现的气田以探明储量小于100亿m^3的为主,且天然气在一次能源消费结构中仅占2%。发展我国天然气勘探的战略是:继续发展对四川、陕甘宁、塔里木、吐一哈、柴达木、琼东南—莺歌海、东海等7个已形成或初步形成的气区的勘探;积极开辟和探索准噶尔盆地腹部、西北侏罗系盆地、南方新区、华北古生界、渤海湾盆地深层、松辽盆地大庆长垣东侧深层等6个新区的勘探工作。
Abundant and various gas reservoirs have been formed in the large numbers of coal measure strata and gas source rocks widely distributed in China. However, the proportion of proved natural gas is below 10% and the proved reserves of the discovered gas fields is generally less than 100×10~8m^3. Moreover,natural gas only makes up 2 percent in the primary energy consumption structure. The exploration strategy of developing China's natural gas is to continuously expand the explorations of seven developed and developing gas areas, such as Sichuan, Shanganning, Talimu, Tu-Ha, Chaidamu, QiongdongnanYingehai and Donghai etc., and to actively open up the explorations of six new areas,such as in the centre of Zhungeer,the Jurassic basins in northwest China,the new regions in south China,the palaeozoic strata in north China,the deep zones in Bohai Bay Basin,and the deep zones on the east side of Changyuan,Daqing in Songliao Basin etc.
