摘要
利用一种全新的人工智能技术──人工神经网络,将测井和地面地震资料(如层速度或波阻抗)联系起来,自动建立测井数据、地震数据和告性间的非线性关系,从而有效地进行岩性预测。
At present,it is realistic to integrate well logging and seismic data to predict lithology in reservoir description. The artificial neural network is a quite new artificial intelligence technique. Using this technique,well logging data are combined with seismic data(interval velocities or acoustic impendences)to automatically construct some nonlinear relationship among well logging data, seismic data and lithologic data. By means of this relationship,the lateral prediction of lithology can be Performed effectively.
