摘要:
哈拉阿拉特山地区是准噶尔盆地西北缘前陆褶皱冲断带的一部分。本文以油气地质理论为指导,利用平衡剖面技术对研究区进行了构造演化特征及演变史的恢复,并对该地区的油气源条件、储盖条件、圈闭条件以及运移条件等油气成藏基本条件进行了初步分析与探讨。认为哈拉阿拉特山地区构造演化与准噶尔盆地西北缘密切相关,大致经历了4个演化阶段:即碰撞挤压期(C-P)、弧后挤压期(P2-T)、伸展断陷期(J1-J21)和再生前陆期(J22-Q)。哈拉阿拉特山地区拥有较好的油气源条件,发育有多套储盖组合、不同类型圈闭和复合的输导体系,具备形成油气藏的基本地质条件,具有广阔的油气勘探前景。

Abstract:
The Halaalate Mountain area is located in the foreland thrust zone on the northwestern margin of the Junggar Basin, northern Xinjiang. A preliminary study in the present paper is made for the tectonic evolution, source rocks, reservoir rocks, cap rocks, traps and migration of oil and gas in the study area. Four stages of tectonic evolution have been distinguished, including the collision and compression (C-P), back-arc compression (P2-T), extension-rifting (J1-J21), and regenerated foreland basin (J22-Q) stages. The results of research in this study show that the Halaalate Mountain area is of great potential for oil and gas exploration due to good source rocks and reservoir-seal associations, various oil traps and complex hydrocarbon carrier systems.
Key words:  Halaalate Mountain area  tectonic evolution  hydrocarbon accumulation  source rocks  reservoir-seal association  trap  migration
