摘要： 准噶尔盆地腹部自晚古生代至第四纪经历了台地型海相盆地、前陆型海相盆地、裂陷型残留海盆地、坳陷型陆相盆地、振荡型陆相盆地和收缩型陆相盆地等6个构造、沉积演化阶段；裂陷和坳陷阶段为烃源岩的主要发育时期。本文探讨了烃源岩层的空间分布及热演化史,阐述了盆地腹部的构造及沉积特征,指明存在3个有利含油气领城。

关键词: 构造演化, 烃源岩, 热演化, 有利聚集带

Abstract: Fromn Paleazokc to Quaternary, Junggar Basin Went through six periods of evoluton of structures and depositions, including platform besin of marine facles, foreland besin of marine facias, hollow--rentod basin of relic sea,depression besin of continental facies, vibration basin of continental facles and contracton besin of continental facies. During hollow renting and depression, hydrocarbon source rocks were mainly developed. THis paper probed into the distributiao and thermal evolution of hydrocarbon soutce tock, and presented the charactcriswics of structues and deposi一tions in hinderland of Junggar besin. Three favorable hydrocarbon- bearing areas were polnted out in this pepar.

Key words: structural evolution, hydrocarbon source rocks, thermal evolution, favarable hydrocarbon一bearing belts
