| 摘 要： | 通过分析库车前陆盆地的油气成熟度、烃源岩在主生烃期形成的烃类聚集和库车坳陷特殊的挤压地质条件,指出了库车坳陷陆相烃源岩的主要生油和主要生气的阶段,还指出了最主要的成烃期为康村期至库车期(RO为0.6%～2.0%)。对库车前陆盆地进行了原型恢复(原型盆地是现今的1.5倍,现今南北宽20～67km)和对有机质生烃潜力进行了恢复(恢复到好烃源岩程度)。认为该前陆盆地烃源岩性质与中亚一些盆地具有可比性,库车冲断带上的6个古构造圈闭与主生烃期相匹配,所捕获的油气是库车坳陷整体富气和区带富油的主要因素,库车盆地具有形成大中型油气田的地质条件。

| Abstract: | By studying the maturity of the oil, gas and source rock characteristics in Kuche foreland basin, it is concluded that the main generatin hydrocarbons were the period of the early Kancun, then in the scope of petroleum system, through restoreing residual organic potential and prototype basin, it is concluded that Kuche foreland basin has favourable geochemical conditions of forming the giant and great oil-gas trap.The main generating gas period of Kuche foreland matched with the period forming paleo-structure,and it is easy to accumulate large gas field in the upper neo-structure trap by adjusting and capturing the early accumulated oil and gas in the lower paleo-structure. |
