摘　　要：基于信息熵的概念提出了管段熵和节点熵并且应用于油田注水管网。管段熵量度当管网中包括该管段在内的任意管段破裂时通过该管段的流量的不确定性,节点熵量度的是当管网中任意的一条管段断开时该节点的压力的不确定性。最大熵反映实际工况下系统实现其最佳潜力的能力,反映系统的可靠性。通过对于整个系统信息熵的分析,合理的改造管网结构,提高系统可靠性。Proposed the pipeline node entropy and the pipeline entropy based on the information entropy＇s concept,and applies in the in the oilfield injecting pipeline network.The pipeline entropy measurement in the pipeline current capacity uncertainty when the pipeline networks break at random.The node entropy measures the node pressure uncertainty when the pipeline networks break at random.The biggest entropy reflects the best potential of the system under the actual operating mode,It is reflects the system＇s reliability.Through regarding the overall system information entropy＇s analysis,the reasonable transformation pipe network structure,enhances the system reliability.
