| 摘 要： | 从热力学角度确定了管道停输后最大允许开挖长度的约束条件,并建立了数学模型。分析指出:管道停输允许开挖长度受维修季节、维修时间、出站温度及开挖起点等因素的影响。以中国大庆原油为介质,林源站至太阳升站(两站间距为47.8km)为研究对象,进行模拟计算可知,5月份和10月份维修允许开挖长度较大。当维修时间小于6h,理论上可以全线开挖;11月份不适合停输开挖维修;4月份进行停输开挖维修则需要提高出站温度。同时开挖长度还受开挖起点的制约。

| Abstract: | According to thermodynamics,the constraint conditions of the maximal allowance excavation length under shut down was confirmed and the mathematical model for the first time was established. The analysis results showed that the allowance excavation length of shutdown pipeline depended on several factors including repairing season,shutdown repairing time,the oil temperature at the outlet of heating station. Some simulation and calculation were did taking China east pipeline from Tai Yang Sheng station to Lin ... |
