摘　　要：为降低输油管道的能耗水平,降低输送阻力并提高输送效率,现场常采用添加减阻剂的方式作为流动保障方案。在梳理减阻剂减阻效果影响因素的基础上,通过熵权法确定了影响因素重要程度,结合模糊物元模型确定了管道的综合减阻效果,并从原油物性和减阻剂浓度两方面对减阻效果进行优化调整。结果表明:模糊物元模型得到的不同管道综合减阻效果的关联度系数与减阻率和增输率的相关性均较强,可以用关联度系数表示综合减阻效果;采用微波加热对原油进行热处理的效果优于水浴加热方式,微波热处理温度、管输流速和减阻剂浓度均存在最优值;优化后可节约热力费用为0.792~13.508元/t,节约动力费用为0.175~0.896元/t,节能减排效果显著。In order to reduce the energy consumption level of oil pipelines,reduce the transmission resistance and improve the transmission efficiency,the method of adding drag reduction agent is often used as a flow guarantee scheme.On the basis of sorting out the factors affecting the drag reduction effect of drag reduction agent,the importance of factors is determined by entropy weight method.Combined with the fuzzy matter-element model,the comprehensive drag reduction effect of the pipeline is determined,and the drag reduction effect is optimized and adjusted from two aspects of crude oil physical properties and the concentration.The results show that the correlation coefficient obtained by the fuzzy matter-element model has strong correlation with the drag reduction rate and the transport gain rate,and the correlation coefficient can be used to represent the comprehensive drag reduction effect.The heat treatment effect of microwave heating on crude oil is better than that of water bath heating,and there are optimal values of microwave heat treatment temperature,pipeline flow rate and drag reduction agent concentration.After the optimization,the heat cost can be saved from 0.792~13.508 yuan/t,and the power cost can be saved from 0.175~0.896 yuan/t,which is significant on the effect of energy conservation and emission reduction.
