Abstract：Seismic pattern cluster prediction technique is a pattern recognition technique,which has wide ap-plication in the prediction of oil/gas reservoir.The key of successful application lies as follows:1.the quality of seismic data used meet the needs of high S/N ratio,high resolution and hi-fi;2.building up correct geological model (integrative framework) so that can provide good study sample for neural network training;3.selecting neural network with multi-layer sensor.In above-mentioned second link,in concern with formation-partitioning of reservoir it must make effort to refine according to lithology characters,then correctly labele the seis-mic information according to layer-refined data by logging data and build up the link between seismic attributes information and geologic and drilling in-formation.The paper listed the applied cases of two oilfields and further proved application effects of the method.
