Reservoir Prediction Technology Based on Seismic Attribute Optimization
DU Xian-fan · Journal of Yangtze University · 2014
There are abundant seismic and geologic data in seismic attribute,now they are used in fine reservoir description comprehensively.On the basis of theory of multiple linear regression method and through optimizing seismic attribute and seismic attribute combinations,seismic attribute is using as independent variable,and this method is applied for reservoir prediction in Ying 852 Area,optimization of high correlation coefficient of 7kinds of seismic attributes and 4kinds of seismic attributes combinat.The results are proved by drilling practice that the coincident rate of PI oil layer reached 76.2%for drilling sand body thickness.So this method can improve the correlation coefficient of prediction reservoir parameter and well reservoir parameter,and can improve the prediction accuracy of reservoir,through optimizing seismic attribute and its combination.
