摘要： 在塔里木盆地东南坳陷江尕勒萨依发现了中侏罗统杨叶组好烃源岩。该湖相烃源岩以泥岩为主，厚度大约288 m，有机质丰度较高，有机碳含量一般大于2.0%，生烃潜力一般在2 mg/g以上，有机质类型为Ⅱ-Ⅲ型，热压模拟实验产烃率可达300 mg/g以上，处于低成熟—成熟热演化阶段。证实瓦石峡凹陷中南部杨叶组湖相烃源岩发育，成烃条件好，具有较好的勘探前景。

Abstract: The good source rocks discovered in Yangye formation of the Middle Jurassic in Jianggalesayi area of southeast depression in Tarim basin are dominated by lacustrine mudstone, with thickness of about 288 m, high organic matter abundance, and characterized by TOC of generally greater than 2.0%, hydrocarbon?generating potential of over 2.0 mg/g, kerogen types of II and III, as well as hydrocarbon?generating rate of 300 mg/g·TOC by high temperature and pressure simulation experiment. It is confirmed that the lacustrine source rocks of Yangye formation in the low mature?matured thermal evolution stages are distributed in south?central part of Washixia sag, with good hydrocarbon generating conditions, and certainly, it will be of a bright prospects for petroleum exploration
