摘　　要：油田注水管网系统属于大规模复杂网络系统。由于注水系统长期运行,管线普遍存在老化结垢等问题,从而导致管网系统水力摩阻系数发生改变,使得仿真模型得出的结果和真实值会有较大的偏差。为了解决这一问题,本文建立了油田注水管网系统的仿真校正模型。通过把由于水力参数改变而导致的误差转化为等效管长的思想,将误差求解问题转化为优化问题,利用列队竞争算法来进行求解。校正后的仿真计算结果与实际生产数据更相符。校正后的仿真模型为油田注水操作提供可靠的指导。As a complicated large-scale network system,the hydraulic friction coefficient of oilfield water injection system has been changed owing to long time operation,aging and scaling.There is a big deviation between the results calculated by the traditional simulation model and measured values.To solve the problem,a correcting simulation model is established and solved by the Line-Up Competition Algorithm.Through the method that errors are transformed into equivalent tube lengths,the result of the correcting simulation model is close to actual production data.It can possess good guiding significance for oilfield water injection operation.
