摘　　要：CP网络具有分类快速、准确等优点。文中详细介绍了CP网络的算法 ,并对其进行了部分改进 ,增加了误差检验和网络测试功能 ;使用VisualBasic 6 .0开发了相应仿真软件 ,并将其用于某油田的油、水层快速识别。实际应用表明 :改进的CP网络训练周期短、识别准确率高 ,完全可以用于油、水层等的快速识别 ,具有广阔的应用前景。The Counter Propagation network is excellent in solving the sorted problems. It can sort effectively, and its algorithm is concise. This paper describes in detail the algorithm of CP network and its improvement the addition of error processing and network testing functions. The authors developed its simulated software by using the Visual Basic 6.0 and utilized it to identify the oil water layers. Practice shows that the training period of the improved CP network was short and its identification ratio was very high. It can realize the quick identification of oil-water layers and will hence have a very wide application prospect.
