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.
