摘要
///The Zhujiangkou Basin is a special tectonic location of passive continental margin with complex regional background and oil and gas geological conditions. The region has not only basic characteristics of Cenozoic continental rift and fault basin in eastern China but also its unique features. There exist high geothermal gradient and large heat flow in this area, and the thermal evolution of the source rocks is at the stage of mature-highly mature condensate oil and wet gas. Besides,there is mixed source mechanism of hydrocarbon migration and accumulation characterized by the hydrocarbon system of Oligocene delta coastal sandstone and the deep-water fan system.
