| 摘 要： | 地层沉积、地震剖面与露头资料并结合平衡剖面的研究,表明库车三叠纪盆地属于前陆盆地,侏罗纪与早白垩世盆地属于造山期后超大型盆地中克拉通边缘凹陷型盆地,它们具有不同的北部边界和沉降特征。三叠纪盆地的北部边界位于现今盆地北部边界以北6～21km的位置,而沉降中心则位于现今南天山山前及山下的中-西段;侏罗纪盆地的北部边界位于三叠纪盆地之北,沉降中心则位于现今南天山山前及山下;早白垩世盆地的北部边界位于侏罗纪盆地之南,东段则已到达了现今边界以南的位置,而沉降中心已接近拜城北部。基于上述,建议在分析油气成藏时首先应进行三叠纪与侏罗纪烃源岩的分布研究。

| Abstract: | Based on the sedimentary features, seismic profile, field outcrop observation and balanced cross-section restoration, the paper presented systematically the Mesozoic prototypes of the Kuqa Basin. It was indicated that the Kuqa Basin was a foreland basin in Triassic, and a sag-type basin in a post-orogenic super-large basin during Jurassic and Early Cretaceous, which almost had the same south boundaries but varied north boundaries and had different subsiding features in the above three periods. The Triassic basin had a north boundary to the north of that in present, with a distance about 6 to 21 kin, and a subsiding center under the southern Tianshan Mountains today. The Jurassic basin also had a subsiding center under the southern Tianshan Mountains today, and a north boundary to the north of that of the Triassic basin. The Early Cretaceous basin had mainly two subsiding centers close to Baicheng county, with the north boundary being located to the south of that of the Jurassic basin, which might arrive to the south of that of the present basin in the eastern Kuqa Basin. According to what mentioned above, the paper suggested that the most important work on analysis of the oil and gas accumulation in the Kuqa Basin should be restoration of the distribution of Triassic and Jurassic source rocks. |
