摘要/Abstract

摘要： 为保障原油管道河流穿越段安全、高效地运行,需对沥青质沉积进行研究,评估原油管道河流穿越段长期运行的安全性。通过对原油组分、沥青质沉积机制的研究,结合某河流穿越段的复杂流动环境,采用计算流体动力学(CFD)方法,研究该管段原油对沥青质颗粒的携带作用以及沥青质颗粒的运移过程,并定量分析沥青质的沉积量,从而评估该管段的安全性。结果表明:在当前输送工艺条件下,河流穿越段输量下降了0.94%,处于安全运行阶段。

关键词: 原油管道河流穿越段, 计算流体动力学(CFD)方法, 沥青质沉积, 携带作用, 安全评估

Abstract: In order to ensure safe and efficient operation of river crossing section of crude oil pipeline, it is necessary to study asphaltene deposition and evaluate long-term operation safety of the river crossing section. Based on findings of crude oil components and asphaltene deposition mechanism as well as complex flow environment of certain river crossing section, CFD method was used to study carrying effects of crude oil on asphaltene particles and transport process of these particles. Then deposition amount was quantitatively analyzed so as to evaluate safety of this section. The results show that transportation volume decreases by 0.94% in river crossing section in terms of current current transportation technology, and it is in safe operation stage.

Key words: river crossing section of crude oil pipeline, computational fluid dynamics (CFD) method, asphaltene deposition, carrying effect, safety evaluation
