HYDROCARBON-GENERATING POTENTIALS FROM SOURCE ROCKS WITH DIFFERENT FACIES IN YANAN FORMATION,LINGWU COALFIELD

For the research on the hydrocarbon-generating potentials from source rocks with different sidimentary facies,the Yanan Formation in Lingwu Coalfield,Ningxia,is selected as the research object.The source rocks with different sedimentary facies in the lacustrine-delta system are pyrolyzed and analyzed,the types oil source rock or the types of organic matter are divided,and the hydrocarbon-generating potentials from source rocks with different sedimentary facies are analyzed.
