摘要
西北地区三大板块(塔里木、准噶尔-阿尔泰、阿拉善-柴达木)的离散、敛合、碰撞控制着西北诸盆地的形成发展。原型盆地的叠加复合构成了不同类型的含气(油)盆地(塔里木)、含油(气)盆地(准噶尔、柴达木、伊宁、吐鲁番-哈密)、含油盆地(酒西、三塘湖、民和、巴丹吉林-腾格里诸盆地)。其中以塔里木盆地含气前景最大,准噶尔、柴达木盆地次之,伊宁、吐-哈盆地前景较小。
Abstract
The divergence,convergence and collision of the three main plates(Tarim,Junggar-Altun and Alxa-Qaidam)controlled the formation and development of the basins in Northwest China.The superimposed-composite prototype basins constituted different types of gas(oil)-bearing(Tarim),oil(gas)-bearing(Junggar,Qaidam,Yining,Turpan-Harmi)and oil-bearing(west Jiuquan,Santanghu,Minhe and Badain Jaran-Tengri)basins.Among these basins,the most potential gas-bearing basin is the Tarim,then the Junggar and the Qaidam Basins,the Yining and the Turpan-Hami Basins less favourable.
