摘要
Based on fine horizon calibration of the third member of Shahejie Formation in Liaozhong Depression, seismic stratigraphic interpretation is completed by seismic modeling.Based on the analysis of seismic facies and sedimentary facies,seismic-sedimentary facies models are established and distribution of high-quality hydrocarbon source rocks of Shahejie Formation in Liaozhong Depression is predicted.The results show that high-quality hydrocarbon source rocks is mainly distributed in the north sag of Liaozhong Depression,the range decreases gradually from north to south.
