摘要

A method in oilfield w ater injection pipe netw ork based on partition and mutual back‐up is adopted aiming at the reliability and complexity in this network .According to the princi‐ple of water ,transverse and longitudinal cut ,a reliable and fast approach to topology optimiza‐tion is designed .Through the simulation of Daqing oilfield water injection pipe network topolo‐gy ,the relationship between node degree ,the average degree of network ,the node′s flow and pressure loss ,the utilization rate of node and flow before and after optimization are analyzed . Experimental results show that the method of partition topology optimization has a small net‐work average degree and higher node and traffic efficiency .Meanwhile ,it can better ensure the reliability of the operation in the whole water injection pipe network .%针对油田注水管网拓扑结构的可靠性和复杂性问题，根据管网水源和横切纵切原则，采用分区互为备份的方法，实现一种高可靠性的注水管网拓扑快速优化方法。通过对大庆油田注水管网拓扑结构的优化仿真，分析分区优化前后网络中节点度数、网络平均度数、节点流量和压损、节点可利用率以及流量可利用率的关系。结果表明，分区拓扑优化具有网络平均度数小、节点和流量可利用率高的优点，更好地保障了整个注水管网运行的可靠性。
