摘　　要：准噶尔盆地位于新疆北部,面积13×104 km2.目前已发现30多个油气田。经研究认为,该盆地具有前震旦系结晶变质基底,在纬向、西域系和北东向构造体系控制下,发育广泛的古生代沉积。盆地原型:震旦-奥陶纪为裂陷-克拉通盆地,志留-泥盆纪为挤压裂谷-克拉通盆地,石炭-二叠纪为类克拉通坳陷盆地。发育三套烃源岩(-O、S1及C-P),油气资源十分丰富,是当前和今后油气勘探重要领域,并指出,准西北、准东和陆梁等地区是寻找古生代油气田的有利区(带)。Junggar basin is located in northern Xinjiang and has an area of 13×104 km2.More than 30 oil and gas fields have been found up to now.The study shows that this basin has crystalline and metamorphic basement of pre-Sinian,and develops broad Paleozoic sediments under control of latitudinal Xiyu system and NE-trending tectonic system.The prototype of the basin is composed of the rifted-cratonic basin of Sinian-Ordovician,the compressional rifted-cratonic basin of Silurian-Devonian and the craton-like depression basin of Carboniferous-Permian.There exist three sets of source rocks of the Cambrian-Ordonican,the Lower Silurian and the Carboniferous-Permian,which contain very abundant hydrocarbon resources and play important roles in petroleum exploration at present and for the future.It is suggested that the northwestern Junggar basin,the northern Junggar basin and Luliang area are the favorable domains for exploration of oil and gas fields of Paleozoic.
