Oilfield Water Injection Pipe Network Topology Optimization Research Based On Electromagnetism-like Mechanism Algorithm

Oil field injecting water is to make the wells output of more crude oil,plays the role of adding energy and displacement for reservoir,oil field water injection pipe network is a large-scale network system,is an important part of water injection system.The pipeline investment accounts for about 40%of the total investment of water injection system or so,therefore,optimizing the network can save pipeline and save a lot of money.This paper tried to apply electromagnetic-like mechanism algorithm in oilfield water injection pipe network topology research,to determine the subordinate relationship between the injection wells and water distribution room,between water distribution room and water injection station location,obtained the optimal scheme of topological structure of the network for the shortest line.Because of the complexity of the water injection pipe network optimization problem,decompose the problem into the two sub-problems:one is the determination of the subordinate relations,namely,the optimal division of injection wells;other is the station site optimization of water injection station and water distribution room,thus,the overall layout of pipeline network is optimized.In the whole layout optimization process,the electromagnetic-like mechanism algorithm is applied in oilfield water injection pipe network optimization design,and compared with the traditional design method,the results show that this method is better,and can effectively solve topology layout optimization problem of the oil water injection pipe network,get shorter pipeline and save pipeline investment.
