The factors affecting postfrac productivity are discussed in the paper. The grey associability ordering indicated that the postfrac productivity was lowly correlated with the permeability interpreted by the original log data and mainly influenced by porosity, then effective thickness, and then shale content and formation pressure. In light of the genetic neural network method, the productivity of gas well was predicted by use of the log data through programing and model training. The error detecting result proved that the model was reliable and a good application effectiveness was obtained.

文章对压后影响产能的因素进行了讨论，灰关联度排序表明，压后产能与原始测井解释的渗透率关联性小，而主要影响因素依次是孔隙度、有效厚度、泥质含量和地层压力；引用遗传神经网络法，编制预测程序，利用测井资料通过模型训练，对气井的产能进行预测，误差检验验证了模型的可靠性，取得了良好的应用效果。

For the mapping problems in binary field, a learning algorthm is given to choose better hidden nodes for multilayer feedforward networks, by means of solving maximum separated groups.(7) Expert system for evaluating oil shale is constructed based on neural networks.
