中文摘要：
基于时间序列预测思想构建了适合于煤层气井产能预测的BP神经网络模型。以潘庄CM，井为预测实例，结果表明：该模型能够较为准确地预测出煤层气井未来30天的产能变化，其产气量和产水量预测平均相对误差分别为1．359／6和3．88％，从而可为煤层气井排采制度的调整提供依据。
英文摘要：
In order to achieve the purpose of real-time dynamic monitoring and forecasting the coalbed methane well productivity, so build the BP neural network model that based on time series prediction idea suitable for coalbed methane well productivity prediction. Use Panzhuang CMlwell for forecast instance, the results show that. this model can accurately predict the pro- ductivity change of the CBM wells in the next 30 days , the average relative error of gas produc- tion and water production forecast respectively 1.35% and 3.88%, thus provide the basis for the adjustment of the coalbed methane wells drainage system.
