It is known that the genetic algorithm(GA)is good at global searching,and the artificial neural network(ANN)is effective on accurate local searching,On this basis,we proposed a method to combine GA with BP algorithm and through GA optimizing BP network to forecast oil and gas yield,and it does well in the research of improving the precision of forecast,On the forecast of an internal gas field' yield,we test the method by historical data,the result indicates that the precision of the method which is proposed obviously overmatches BP algorithm,and the effectiveness and reliability of this method have been proved.
