The H4b reservoir of Bajiaoting structure in Pinghu oil and gas field is characterized by thin layers and strong heterogeneity, and it was developed by multi-branch horizontal wells, which makes reservoir description and reservoir modeling difficult. Based on well drilling and 3D seismic data, detailed stratigraphic correlation and prestack inversion techniques were applied to predict the reservoir distribution. The drilling trace of horizontal wells was fully used to adjust the reservoir description results, and the target reservoir is taken as single sand body or flow units for geological modeling. By taking the advantages of the long drilling trace of horizontal wells and wide horizontal cover of physical properties, combined with seismic attribute constraint, the model suitable for dynamic and static geology was finally established.
