大气温度年周期性变化对集油管道温降的影响研究

油田集油管道的温降计算是否准确直接影响到油田能耗的高低及油田集输管道的安全性。建立了土壤自然温度场模型,并与实测数据进行了比较,结果表明,按大气温度年周期性变化计算土壤温度场方法是可行的,误差在工程允许范围内。同时,分析了油田集输管道温降的影响因素,得出了大气温度年周期性变化对集油管道温降的影响,结果表明:同一埋深管道的温降随大气温度年周期性变化而变化,埋深变化时,集油管道的温降随大气温度年周期性变化时延迟时间不同。

Study on temperature drop of the oil pipeline with annual cyclical changes in atmospheric temperature

The Oil pipeline calculation of the temperature drop a direct impact on the accuracy of the level of oil consumption and oil gathering and transportation pipeline security. The natural soil temperature field model and the data were compared with the measured results show that,according to cyclical changes in atmospheric temperature calculated annual soil temperature field method is feasible,the error in the engineering permitted range. Meanwhile,the analysis of oil field pipe temperature drop of the influen...
