摘要
西北缘是准噶尔盆地的主要油气聚集区之一,勘探程度较高.从含油气系统观点出发,以烃源岩为主线,以地质作用为切入点,总结了西北缘油气富集规律.西北缘位于玛湖—盆1井西复合含油气系统主体部位,油源十分充足,为油气大规模聚集成藏奠定了基础.西北缘油气分布受油气系统、断裂、区域盖层及不整和等因素控制.
The northwest edge is one of the most important oil and gas accumulation belts in Junggar basin and has been highly prospected. With the viewpoint of oil and gas accumulation system, we discussed the source rock and geological processes related to the belt, and summarized the rule of oil and gas accumulation in the northwest edge of Junggar basin. The northwest edge of Junggar basin locates at the principal part of the composite petroleum system of Mahu-west of well Pen 1 and has rich oil source. The hydrocarbon distribution of the northwest edge of Junggar basin is mainly controlled by petroleum system, falts, regional cap rocks and unconformity surfaces.
