摘要: 从有机质类型、丰度及热演化程度三个方面对塔东北地区侏罗系层序地层格架中的烃源岩进行评价,查明了侏罗系各体系域的生烃能力。认为,侏罗系层序烃源岩处于未成熟一成熟阶段,低位及高位体系域烃源岩有机质丰度过低,生烃能力较差;湖侵体系域烃源岩丰度较高,以中等生油岩、好生油岩及煤岩为主,生烃能力较好。

Abstract: In view of types, abundances and thermal evolution properties of organic matter, an evaluation of the hydrocarbon source rock within Jurassic stratigraphic sequence framework in northeastern area of Tarim basin is made, ascertaining the source potential in Jurassic hydrocarbon source rocks lie in unmatured -matured stage, where low and high level system tracts have organic matters of too low abundance, with poor source potential; while lacustrine system tract has more abundant hydrocarbon source rocks consisting mainly of medium and fair source rocks as well as coal measures, with good source potentials.

Key words: Tarim basin, Northeast, Sequence stratigraphy, Source bed, Evaluation
