利用petromod盆地软件,在准噶尔盆地南缘四棵树凹陷埋藏史、热史的基础上,进行生烃史模拟与分析,研究表明:工区西北部地层比东南部地层埋深浅,因此烃源岩演化程度要低,安集海河组烃源岩主要在新近纪晚期达到生烃门限,独山子地区则是在新近纪中期达生烃门限。中下侏罗统烃源岩生烃门限时间,由工区西北向东南方向逐渐变早。 The petromod basin software was used to simulate and analyze the hydrocarbon generation history on the basis of the burial history and thermal history of the Sushu depression on the southern margin of Junggar Basin. The results show that the strata of the northwestern part of the work area are shallower than the southeast part, so the evolution of source rocks To a lesser extent, the source rocks of the Anjihaihe Formation reached the hydrocarbon generation threshold mainly in the late Neogene, and the Dushanzi reached the hydrocarbon generation threshold in the mid-Neogene. The hydrocarbon generation threshold time of the Middle-Lower Jurassic source rocks gradually changes from northwest to southeast of the work area.
