Abstract: The method of reservoir transverse prediction is inexpensive and effective,which is often used to makea preliminary study on a reservoir in the case of few wells available,using seismic data in combination oflogging and geological information.The paper uses 2-D and 3-D seismic data to predict the distributioncharacteristics,thickness,porosity,permeability and oil saturation of Eogene bottom sandstones in YM 7-9 wells region.The results are satisfactory.The key to a reservoir prediction by seismics is a precise demarcation of the horizon and making a PIVT section.
