【摘要】 塔里木盆地北部地区中生界生油岩为陆相泥质生油岩，主要发育在三叠系、侏罗系。有两个生油岩发育中心，库车坳陷区和阿瓦提断陷－满加尔坳陷区。三叠系生油岩有机质丰度主要为较差一较好生油岩，侏罗系生油岩则为较差－较好－好生油岩。三叠－侏罗系生油岩干酪根类型以Ⅲ型为主，少量Ⅱ型。库车坳陷三叠－侏罗系生油岩热演化多处于成熟－高成熟阶段。阿瓦提断陷－满加尔坳陷三叠系处于初熟阶段，侏罗系则处于未成熟－初熟阶段。沙雅隆起北侧，库车坳陷南缘是寻找油气藏最为有利的地区。更多还原

【Abstract】 The Mesozoic source rocks at the northern Tarim basin belong to argillaceous rocks of continental facies, which are mainly developed in the Permian System and Jurassic System. Two well-developed centres of source rocks are Kuqa depression area and Await-Manjar depression area. The organic matters’s abundance of Triassic source rocks mainly range from worse to better, while of Jurassic from worse to better to best. The Kerogen type of Triassic-Jurassic source rocks is dominated by Ⅲtype with minor Ⅱtype. The thermal evolution of Triassic-Jurassic source rocks in Kuqa depression is mainly in a matured to highly-matured stage. While for Await-Manjar depression,that of Triassic source rocks in a low-matured stage,and of Jurassic in a prematured to low-matured stage. The advantageous areas to search Mesozoic oil-gas pool concentrate on the northern Shaya uplift and southern Kuqa depression.更多还原
