焉耆盆地处于塔里木盆地与吐哈盆地之间，构造格局为两坳（ 和静坳陷、博湖坳陷） 一隆（ 焉耆隆起） ，晚古生代为南天山前陆盆地的组成部分（ 早二叠世回返） ，中三叠世至侏罗纪形成南深北浅的箕状断陷，白垩纪至古新世隆升，始新世以来成为南天山类前陆盆地。焉耆盆地中生界的成熟烃源岩为三叠系小泉沟群和下侏罗统八道湾组的煤系地层（ 主要分布于博湖坳陷） ，构成博湖坳陷三叠系—侏罗系含油气系统（ ！） ，燕山中期（ 侏罗纪末） 第一次成烃充注，喜山期（ 晚第三纪） 第二次成烃充注。根据博湖坳陷北部凹陷和南部凹陷油气生、运、聚的差异，其含油气系统可划分为北部凹陷运聚子系统和南部凹陷运聚子系统，论述了二者地质事件和关键时刻。北部凹陷运聚子系统石油资源量为１ ．８４×１０８ｔ，天然气资源量为５２５ ×１０８ｍ３ ，是焉耆盆地油气勘探的主要领域（ 已发现的宝浪油田和本布图油田均位于北部凹陷） 。图５ 参３（ 王孝陵摘）
The Yanqi Basin is located between the Tarim Basin and the Turpan-Hami basin. Its structure is composed of two Au (Hejing Depression and Bohu Depression) a Long (Yanqi uplift), and the Late Paleozoic is an integral part of the southern Tianshan foreland basin The Middle Triassic to the Jurassic formed a minor southern-northern-shallow graben-like rift that rose from the Cretaceous to the Paleocene, and became the southern Tianshan foreland basin since the Eocene. The mature source rocks of the Mesozoic in the Yanqi Basin are Triassic Junco strata and Lower Paleo-Badaowan coal measures strata (mainly distributed in the Bohu depression), forming the Triassic-Jurassic It is the first hydrocarbon accumulation charge in the mid-Yanshanian (Late Jurassic) and the second hydrocarbon charge in the Himalayan (Late Tertiary). According to the difference of hydrocarbon generation, transport and accumulation in the northern and southern sag of the Bohu Depression, the petroleum systems can be divided into the transport system of the north depression and the migration cohesion subsystem in the southern depression. The geological events and key moments of the two events are discussed. The amount of oil resources in the north sag system is 1. 84 × 108t and natural gas resources amounting to 525 × 108m3. It is the main area for oil and gas exploration in the Yanqi Basin (both the Baolang and Benburu fields are found in the northern depression). Figure 5 reference 3 (Wang Xiaoling pick)
