Natural gas produced in Malang sag of Santanghu basin features high hydrocarbon content and high drying coefficient,with carbon isotope relatively light of methane and heavy of ethane and propane,which meets the characteristics of bio-thermocatalytic transitional zone gas through comprehensive analyses.The organic matter in middle to upper Triassic and middle to lower Jurassic coal measure source rock,which is the major source rock of natural gas in the basin,is type Ⅲ,and at its transitional zone gas evolution.
