摘要： 库木塔克凸起是吐哈盆地吐鲁番坳陷前侏罗系5大古凸起之一,是吐哈盆地前侏罗系油气最为富集的古凸起。因该区的成藏条件、成藏规律和勘探方向尚不是很清楚,制约了该区的勘探进程。近几年的研究表明,持续发育的古凸起既控制了烃源岩的分布,同时也控制了有利储集相带的分布和油气运聚的方向。通过研究,明确了前侏罗系成藏模式为砂岩侧向运移、剥蚀地层圈闭背景下发育的下生上储的构造-地层油藏;侏罗系成藏模式为不整合面侧向运移、超覆地层圈闭背景上发育的下生上储的构造-岩性油藏。

Abstract: Kumtak swell is one of the five large swells of pre-Jurassic in Turpan depression of Tuha basin. Up to now, it is believed to be the most hydrocarbon-enriched ancient swell among the five swells. But it is unclear that the conditions and rules of hydrocarbon's generation and reservation as well as its exploration target, which restrict its hydrocarbon exploration progress. The past-year experiences show that continuously developed ancient swell controls not only distributions of source rocks and reservoir facies belt, but also the direction of hydrocarbon migration. The research shows that hydrocarbon accumulation pattern of pre-Jurassic is the structuralstratigraphic reservoirs with source bed in lower formations and reservoir bed in upper formations under the settings of lateral migrated sandstone and denudated stratigraphic traps, and that of Jurassic is the structural-lithologic reservoirs with the same way under the settings of lateral migration of unconformity and overlying stratigraphic traps.

Key words: Tuha basin, Kumtak swell, hydrocarbon accumulation, rule, mode
