Optimization of oil field injection pipe network model based on electromagnetism-like mechanism algorithm

Abstract

The accuracy of water injection pipe network hydraulic model is directly related to the fitting degree of water injection pipe network actual running state. In order to improve the accuracy, using optimization algorithm of electromagnetic-like mechanism to correct the pipe friction coefficient was introduced. To meet constraint conditions, such as the pipe network hydraulic balance and range of parameters, establishing a new oil field injection water distribution network optimization model, the experience estimate of the pipe friction coefficient was introduced to the electromagnetic mechanism optimization algorithms in order to achieve the pipe friction correction. The results show that the node flow calculated value obtained from using the electromagnetism-like mechanism optimization algorithm calibrate water injection pipe network hydraulic model is in good agreement with node actual flow. © 2011 Springer-Verlag Berlin Heidelberg.
