摘要
准噶尔盆地腹部可划分出5凸、5凹10个二级构造带;存在3套可信的烃源岩层:下二叠统风城组、上二叠统下乌尔禾组和侏罗系煤系,确定了其空间分布和热演化史;分析了油气二次侧向运移的聚散规律,指出油气聚集的有利地区并定量计算了油气聚集量;最后,探讨了该区油气藏的形成条件和特征。
There are ten second-order structural belts including five depressions and five arches in the hinterland of Junggar Basin. Lower Permian Fengcheng Formation, Upper Permian Low Urho Formation and Jurassic coal-containing Formation are proven source beds. In this paper , the special distribution as well as their history of thermal evolution of these source formations are illustrated, the lateral secondary migration of oil and gas and their accumulation are analyzed; the areas favorable to the accumulation of oil and gas are pointed and the amount of oil and gas accumulated is estimated. Finally the conditions of the formation of oil and gas reservoirs and their characteristics are discussed.
