Prediction Method Based on Improved ABC Algorithm and RBF Neural Network

In order to solve the problem of low prediction precision and long prediction time of steam flooding development effect, we propose a novel prediction method, which is based on the combination of improved artificial bee colony algorithm and RBF(Radial Basis Function)neural network.In the proposed method, we apply the optimal solution of the population to modify the search equation of the employed bees and the onlooker bees,perform the random perturbation of the population optimal solution and individual search solution with the idea of differential evolution algorithm, and adopt hybrid encoding to optimize the parameters of RBF neural networks.We use the Qi 40 block of Liaohe Oilfield as an example and make a trial calculation.The trial results show that the method has better nonlinear fitting ability and higher prediction accuracy for steam flooding development effect prediction.
