BP Neural Network Based on Genetic Algorithm to Predict Oil Single Well Production

The prediction of oil single well production is of great significance to the sustainable and stable development of oil field production.In this paper,a back propagation neural network(BPANN-GA)based on genetic algorithm is proposed to predict single well production,aiming to deal with the problems in traditional prediction methods such as complex modeling and low prediction accuracy.Meanwhile,the traditional BP neural network algorithm is characterized by its slow convergence and the possibility of falling into local optimum.In addition,instance analysis is done on the newly proposed method and comparatively higher accuracy for prediction can be obtained.It can be concluded that the algorithm is simple and practical,with high prediction accuracy,fast convergence,and no possibility of falling into local optimum,which has certain significance for the prediction of single well production.
