Application of Seismic Reservoir Description Technique in CFD11-6 Oilfield Reserve Evaluation of Bohai Offshore Area

The CFD11-6 oilfield lies in the Bohai offshore area,the main zone of this oilfield is fluvial reservoir of Minghuazhen formation.The thin thickness,great lateral changes and poor continuity are the main features of fluvial reservoir,it is hard to describe the fluvial reservoir.Many seismic reservoir description methods of fluvial reservoir were applied widely now.According to study the geological and geophysical features of CFD11-6 oilfield,the log constrained inversion and seismic attribute techniques were selected to describe the reservoir of this oilfield.The data of development proved that this method can meet the need of reserve evaluation and provide the experience for the other oilfields of Bohai offshore area.
