Abstract

Abstract:

In the process of oil pipelines’starting to convey, precise calculation and prediction of temperature field of the soil around pipelines and law of medium temperature in the pipelines changing with time are the key to identify the time of putting oil in and preheat medium totals. By water as preheat medium, and calculations of conducting heat’s numbers in the process of pipelines’ preheat under different flowing speed circumstances, it analyzed distributions of temperature field of the soil around preheat pipelines and temperature dropping along pipelines with distances, and finally get oil pipelines’ preheat conditions under flowing speed of various medium, which can help set corresponding oil-conveyed technique and attain the goal of safety and saving energy.

摘要： 输油管道在启输过程中,准确计算和预测管道周围土壤温度场以及管内介质温度随时间的变化规
律,是确定合理投油时间和预热介质总量的关键。以热水为预热介质,通过不同流速条件下管道预热过程传热数值
计算,对预热管道周围土壤温度场的分布及管道沿程温降进行了分析,得出了介质在不同流速下,输油管道预热情
况,利于依此确定相应的输油工艺,达到安全节能的目的。
