埋地热输原油管道在线修复时站间温降随输量的变化

Variation of intersite temperature drop with throughput when repairing on-line buried hot crude oil pipeline

针对原油长输管线局部大修时出现凝油事故的问题进行了研究。采用分段法计算埋地热输原油管道在线修复时站间的温降随输量的变化,并用C语言编制了计算程序,进行了实例计算;指出提高原油流量是减小站间温降,防止凝油事故的有效方法.

Calculates the variation of intersite temperature drop with throughput when repairing on- line bured hot crude oil pipeline by sectioning method, makes the computer program by C language, calculates the examples by it. Puts forward that increasing throughput of crude oil is effective method to decrease intersite temperature drop, prevent freezing oil.
