摘要
Abstract
In view of the slow convergence speed and low precision of oilfield production prediction algorithm,a prediction al?gorithm of oilfield production based on BP network algorithm is proposed in this paper. The algorithm through the forecast weight ad?justment operator into the adaptive algorithm in the BP network,in the process of optimization of reverse bias to adjust the connec?tion weights of the network,accelerates the prediction speed of convergence of the algorithm,and makes the algorithm to get rid of possible defects in the local optimal sample data under the condition of insufficient,reduces the prediction results of deviation that makes up the disadvantage of the traditional BP network prediction algorithm. Finally,a numerical example is given to demonstrate the effectiveness of the proposed algorithm and the advantages of the traditional BP network algorithm.关键词
