摘　　要：运用Petromod盆地模拟软件,对准噶尔盆地南缘中段进行了一维的地史、热史和生排烃模拟。结果表明,准噶尔盆地南缘中段现今地温梯度较低,仅为13.2-20.6℃/km;霍玛吐背斜带（第二构造带）为两期成藏,安集海背斜、呼图壁背斜组成的第三构造带为一期成藏;研究区下白垩吐谷鲁群组已经进入生油高峰,生油高峰在20 Ma左右;生烃中心位于玛纳斯背斜和吐谷鲁背斜区域,吐谷鲁背斜烃源岩已经开始生气。Learning of Petromod basin simulation software, we have simulated one dimensional geologic history, including thermal history and hydrocarbon expulsion history in the middle of the southern margin of Junggar basin. Geotemperature in middle of the southern fringe of Junggar basin is a little low,only 13.2 -20. 6℃/km. There are two stages of petroleum accumulation in Huomatu anticline belt （the second structural belt） ,one stage in Anjihai and Hutubi anticline （ the third structural belt） . The Lower Cretaceous Tugulu Formation in the study area has entered the peak of oil generating. Hydrocarbon generation center in Manas and Tugulu anticline area. Source rock in Tugulu anticline has got its hydrocarbon generation threshold. Hydrocarbon source rocks will begin to produce gas.
