中文摘要:
      随着投用时间的增长和产量的变化,塔河油田原油管道在生产运行过程中会处在低输量的状态下。由于环境温度变化较大,所输油品凝点粘度较高等因素,重油管道在低输量条件下有可能会陷入不稳定工作区甚至发生凝管停输等危险。本文调研了原油管道安全输量的相关文献,针对塔河油田塔雅管线的实际运行状况,考虑了管道运行过程中摩擦热的影响,建立了管线运行时的平衡方程式。运用逐步搜索法,通过输量和终点温度的关系得到了热力学最小输量;通过输量和沿程摩阻的关系得到了水力学最小安全输量。综合得到的输量结果,进行了规律性分析,并针对塔雅管线的运行,提出了建议。
英文摘要:
      With the increase of operation time and the change of output, the crude oil pipeline in tahe oilfield will be in the state of low output in the process of production and operation.Due to the large change of environmental temperature and the relatively high viscosity of the condensate point of the oil transported, the heavy oil pipeline may fall into the unstable work area or even cause the condensate shutdown and other risks under the condition of low delivery volume.According to the actual operation condition of taya pipeline in tahe oilfield, the thermal balance equation of pipeline operation is established.By using the stepwise search method, the thermodynamic minimum throughput is obtained through the relationship between throughput and terminal temperature.The hydraulic minimum safe transport volume is obtained by the relationship between the transport volume and the friction resistance.Based on the results, the regularity is analyzed and some Suggestions are put forward for the operation of Tanya pipeline.
