SUBTLE ANALYSIS ON SEISMIC SEQUENCES IN THE THIRD MEMBER OF THE FUNING FORMATION ON THE NORTH SLOPE OF THE QINTONG DEPRESSION, NORTH JIANGSU BASIN

Based on subtle description on the seismic sequence of primary aim layers,this article makes a comprehensive analysis combined with core and log data,and proves reservoir distribution by VoxelGeo technology.Through the sedimentary microfacies translation of seismic facies,plane maps of seismic facies and sedimentary microfacies are worked out.Thus,the spatial distribution of favorable reservoir can be predicted.
