Abstract: The 3D visual and superimposed technique is usually used in lithologic subtle reservoir prediction.Multiple abnormal features of seismic data are illustrated from different aspects.The distributionprinciple of each feature is summarized,which may help reservoir prediction.Based on the analyses oflithologic subtle reservoir with the above-mentioned technique,taking the Tahe Oil Field as anexample,combined with the 3D visual and superimposed technique,we have carried out reservoirprediction systematically and have achieved good effects.
