对孔雀河地区3套烃源岩地球化学、热演化参数统计分析表明：寒武系-奥陶系烃源岩分布广 、有机质丰度高，演化程度为过成熟；石炭系-三叠系烃源岩主要分布在草湖凹陷，有机质 丰度低，热演化程度为中-晚期；侏罗系烃源岩全区分布，有机质丰度高，除英吉苏凹陷部 分区域进入生油门限，其它大部分区域热演化程度为未熟-低熟，生排烃量有限。通过对全 区13口井单井盆地模拟研究，总结了孔雀河地区3套烃源的3种埋藏热演化模式，即持续深埋 型、二次深埋型和早期深埋、晚期浅埋型，和2种生排烃模式，即多段式、单段式。通过生 排烃模拟表明，本区生排烃量主要以寒武系-奥陶系烃源岩的生排烃量为主，其它2套烃源岩 生烃区域局限且生烃量有限。指出孔雀河地区成藏组合研究应围绕寒武系-奥陶系这套主力 生烃源岩生排烃史进行，其具有自生自储、下生上储2种成藏组合模式。综合研究认为寻找 寒武系—奥陶系烃源岩主要生排烃期形成的古油藏、分析不同期次构造运动对古油藏破坏程 度和研究不同期次断裂系统对油气的疏导、调整作用和对油气分布规律的控制是进一步深化 该区勘探的关键。
 

The geochemical and thermal evolution parametric statistics analyses of three se ts of source rocks in the Kongque river area reveal: wide-spreading, high abund ance of organic matter and post-mature evolution are the characteristics of the  Cambrian-Lower Ordovician hydrocarbon source rocks; the spreading area of the  Carboniferous to Triassic hydrocarbon source rocks is very limited, the abundanc e of organic matter is low and the thermal evolution is during the middle-late  periods; the Jurassic hydrocarbon source rocks are wide-spreading and have high  abundance of organic matter and immature thermal evolution in the major area, t he generation potential of hydrocarbons is limited. From the basin modeling of 1 3 wells in the area, it has been concluded that there are three kinds of thermal  evolutionary patterns, namely, continuous deep burial, secondary deep burial, e arly-stage deep burial, and late-stage shallow burial, and two kinds of hydroc arbon generation patterns: one-step style and multistage style. There are two k inds of pool-forming associations: self-generation and accumulation, lower gen eration-upper accumulation. An integrated study shows that the main task for fu rther exploration is to find early-paleo-oil-reservoirs and analyze their des truction in different stages and the controlling rule of rift systems over petro leum distribution.
