摘要
Abstract
Effective reservoir parameters are important for characterization and evaluation.Traditional methods based on core measurements or petrophysical modeling are either expensive or inefficient,and existing methods based on recurrent neural networks cannot sufficiently capture the global dependencies in the sequences.In this paper,a reliable,low-cost method for reservoir parameter prediction that is sensitive to the global features of logging data is established from actual logging data.The technique is a hybrid deep learning model based on CNN,LSTM,and Transformer encoder,called CL-Trans network.The CL-Trans network firstly uses one-dimensional convolutional layers to mine potential primary features from logging data,then utilizes multiple LSTM layers to establish nonlinear relationships between logging data and reservoir parameters,and finally applies it to a Transformer encoder with a self-attention mechanism to further extract global features from logging data.We used this network to a region of logging data,and predicted porosity and permeability,showing more accurate and stable reservoir parameter prediction results when compared with Random Forest,LSTM,and CNN-LSTM network.关键词
