The daily production of a single well in an oil field can reflect the changes and water reservoir it is important basis for formulating stimulation measures. However, factors that affect are complex, there currently no standard calculation method. In recent years, BP neural networks have been widely used yield prediction, but they problems such as slow convergence speed easy to fall into local optima. response above issues, this paper proposes backpropagation network model WOA-BP based on whale optimization algorithm. Firstly, Spearman Pearson correlation coefficient methods screen feature attributes related input parameters network, with output parameter; Then, Whale Optimization Algorithm (WOA) optimize initial learning rate, weight bias, number hidden layer neurons network; Finally, optimized parameters, prediction constructed. Train evaluate established using real oilfield data, compare models BP, GA-BP, PSO-BP. experimental results show has good performance, determination (R2) 0.9633 mean square error (MSE) 0.0017. It effectively predict aid predicting blocks.
