吐哈盆地构造特征与油气赋存

吐哈盆地是具有双层基底的叠合盆地，被4个华力西期褶皱带围限，根据残余盆地的特点，从盆地周边，基底和盖相互影响的角度，按南北分带，东西分块的格局，将盆地划分为5个构造单元，吐鲁番坳陷，艾丁湖斜坡，了墩隆起，哈密坳陷和南胡戈壁隆起，基底构造控制了这些构造单元的分布。用构造区的概念探讨盖层构造发育规律与区域构造边界之间的成因关系，把盆地内部盖层构造分为4个构造区：喀拉乌成构造区，博格达构造区，哈尔里克构造区和觉罗塔格构造区，并进一步划分了二级构造带，讨论了背斜斜造的主要类型，油气分布规律和勘探方向。

Tectonic Characteristics and Oil and Gas Accumulation in Turpan-Hami Basin

Turpan hami basin,which is surrounded with 4 Variscides,is an overlay basin with a bilamellar basement According to the characteristics of a residual basin,it is divided into 5 tectonic units,such as Turpan depression,Aidinghu slope,Liaodun uplift,Hami depression and Nanhu serir uplift from the espects of interrelationships between the basin surroundings,basement and caprock as well as zoning from the south to north and blocking from the east to west The distribution of tectonic units is controlled by the basement The caprock tectonic within the basin is divided into 4 regions,such as Kalawucheng,Bogeda,Haerlige and Jueluotage regions The classification of second order tectonic zones is given The key types of anticlinal structures,rule of oil and gas distribution and direction of exploration are discussed
