摘要
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变化,并用C语言编制了计算程序,进行了实例计算;找出防止凝油事故的有效方法。
The crude oil solidification accident in buried hot crude oil pipeline during on-line repair was studied.Temperature drop of buried hot crude oil pipeline during on-line repair was calculated by sectioning method,and computation program was compiled by C language,an example was calculated by it.At last,the methods of pre-venting crude oil solidification accident were put forward.
