摘要： 莫北凸起油藏的油气主要为来自盆1井西凹陷二叠系的成熟和过成熟型油气。纵向上莫北凸起的沉积盖层可分为二叠系—三叠系、侏罗系、白垩系—第四系三个构造层。在侏罗系内,油气主要通过断裂运移,好储集层优先聚集油气成藏。侏罗系三工河组砂层厚度大、分布范围广,不易形成岩性圈闭,油气藏以构造型为主。深部三叠—石炭系圈闭有良好的油气聚集条件。

Abstract: The hydrocarbon in Mobei arch reservoir is Permian matured and over-matured oil and gas which mainly comes from the depression to the west of Well Pen 1. The sedimentary cap-rock here could be vertically divided into three structural units, namely the Permian-Triassic, Jurassic and Cretaceous-Quaternary. The hydrocarbon are mainly migrated through the faulting and better reservoir are the first to accumulate hydrocarbon to form oil-gas reservoir. The Sangonghe formation is characterized by Jurassic sand with great thickness and vast distribution, so it is difficult to form lithologic trap, and the reservoirs mainly occurred as structural trap. The deep buried Triassic- Permian traps have quite good conditions for hydrocarbon accumulation.

Key words: Junggar basin, center, depression, Jurassic, reservoir formation, condition, reservoir distribution
