Abstract: The key to increase the efficiency of exploration and development of oil fields in Eastern China is the lateral reservoir prediction and description by using comprehensive method combining seismic data with supplementary geologic data including drilling and well logging data.According to the sedimentary features of thin interbedded sandstones in fluvial facies (meander), the prediction of lithology and favorable play and the lateral prediction of hydrocarbon-bearing region were completed by using comprehensive parameter transformation, artificial neural network, wavelet transform, etc.The results were applied to various aspects of prospective prediction, prospecting target selection, prospecting well location, reserve estimation, exploitation plan design, etc., which were confirmed by the practical exploration.

Key words: fluvial facies, reservoir bed, comprehensive parameter transformation, artificial neural network, wavelet transform, seismic description, Chengdao Oilfield
