中国石油“十一五”天然气勘探新进展与未来大气田勘探新领域分析

New Progress in Natural Gas Exploration during "1th Five-Year Plan"Period and Analysis on PetroChina's New Domains of Large Gas Field Exploration in Future

中国石油"十一五"天然气勘探取得许多新成果和新进展,天然气储量增长进入快速发展的新阶段,发现和落实了一批规模储量目标区,形成了六大天然气勘探的主探区。分析认为,鄂尔多斯、四川、塔里木、柴达木、松辽和准噶尔等六大盆地的大面积砂岩岩性、海相碳酸盐岩、前陆盆地冲断带和火山岩气藏等勘探领域是中国石油未来寻找大气田的主要领域,生物气和非常规气是中国石油未来寻找大气田的重要接替领域。

Many new achievements and new progress in natural gas exploration had been made by PetroChina during the '1th Five-Year Plan'period,the growth of natural gas reserves had entered into a new stage of development,and a group of target areas with large-scale reserves had been found and carried out,forming six main areas of natural gas exploration.Analysis of PetroChina's new domains of large gas field exploration in the future indicates that the large-area sandstone lithology,marine carbonate rocks,thrust belts of foreland basin,and volcanic gas reservoirs of Ordos,Sichuan,Tarim,Songliao,Qaidam,and Junggar Basins are the main realm to find large gas fields in the future.Biogenic gas and unconventional gas are important realm to find large gas fields in the future.
