Abstract：Conventional oil exploration has been mainly conducted in the Longxi area,Daqing Oilfield.There are still abundant residual oil and gas in multiple formations although the area has been explored and developed for many years.However oil bearing beds in the area are characterized by small sizes,scattered distributions,and subtle feature,and they are very difficult to be predicted.To obtain new understanding of reservoirs,we carry out reservoir research with interpretation tools provided by GeoEast.Stratigraphic units are subdivided and analyzed with vertical and lateral magnification.A number of interpretation techniques are used in combination.And fault identification,low relief structure identification,and reservoir prediction are achieved.Minor faults and subtle traps are accurately identified.A few drilled wells based on our proposal yield high oil production.
