摘　　要：准噶尔盆地具有“盆大、水浅、坡缓、振荡性构造运动”的特征,中部1、3区块侏罗系三工河组是准噶尔盆地腹部重要的勘探目的层系,该组沉积时期主要受北西向与北东向物源共同影响,发育浅湖背景下的三角洲沉积,主要发育三角洲前缘水下分支河道与河口坝砂体,具有较好的储集物性。成藏受控于异常高压带、断裂系统、沉积相带、古隆起等因素,其中,车–莫古隆起的发育和演化为该区创造了独特的油气运聚背景,决定了多期构造演化与多期成藏的特点。Big area, shallow water, gentle slope and oscillating movement are the main characteristics of the Junggar basin. The J1s2 formation is the main exploration strata of the block 1 and 3. During the J1s2 sedimentary period, on the influence of the northeast and northwest provenance, it developed the delta front deposition under the mere background there. The subaqueous distributary channel and channel mouth bar reservoir have the better physical property. The res- ervoir formation is controlled by the abnormal pressure belt, fracture system, sedimentary facies tract and ancient uplift. Among them, the development and evolution of Chemo ancient uplift supply the peculiar migration and accumulation background for oil &gas, which determined the characteristics of polyphase structural evolution and reservoir formation.
