Abstract：The interpretation techniques of the GeoEast system have yielded fruitful results in conventional oil and gas exploration. In recent years,as seismic exploration faces more complex structures,tight reservoirs and unconventional oil and gas exploration are widely concerned. Regarding the deep and thin tight reservoirs in Shan 1 member of Qingyang Gas Field,this paper employs the characteristic software GeoEast. The distribution characteristics of thin sand bodies are depicted through restoring paleotopography of Shan 1 sedimentary period and combining with the seismic facies analy-sis and the multi-attribute joint analysis based on artificial intelligence. On this basis,prestack elastic impedance inversion is applied to determine the enrichment area of high-quality reservoirs. The coin-cidence rate between high-quality reservoirs predicted by the proposed seismic method and actual drilling results is up to 88%,which better solves deep and thin tight reservoir prediction problems in this area and provides strong seismic technical support for the rolling development and evaluation of Qingyang Gas Field.
