Over the past 50 years of development, it has entered extra-high water cut stage presently, with sparsely distributed remaining oil. Therefore, to tap the potential of remaining oil in dense well pattern areas, a series of techniques integrating 3D seismic and well data were applied successfully, which are petrophysical analysis, reservoir prediction and reservoir characterization with well and seismic data. The result shows that the boundary and direction of channel sand body can be characterized accurately with the reservoir prediction method incorporating well and seismic data, at the same time, the prediction accuracy of interwell channel sand body is improved, showing significant reference to fine reservoir description and favorable application prospect in the similar old fields.
