摘要/Abstract

摘要：

输油管道泄漏受到人们广泛的关注，泄漏污染物地面特征是输油管道泄漏检测技术应用的基础。建立了埋地输油管道泄漏二维模型，模拟埋地输油管道泄漏污染物地表运移过程，研究不同泄漏孔径和位置对埋地输油管道泄漏污染物地表运移特征的影响。结果发现：泄漏初期，污染物所受阻力均匀，向四周均匀迁移，而且迁移速度前期快，后期逐渐减小；泄漏孔径越大、泄漏孔位置越靠近地表，石油污染物到达地表的时间越短，水平最大位移量越大，地表特征越明显。

Abstract:

The leakage of petroleum pipelines has been widely concerned by people and surface transport characteristic of leakage contaminant is the basis of petroleum pipeline leakage detection technology application. This paper established a two-dimensional mathematical-physical model of buried petroleum pipelines leakage,and aimed at the surface transport process of leakage contaminant of buried petroleum pipelines,using the numerical simulation software,it is studied on the effect of different leakage aperture and location for the surface transport characteristic of leakage contaminant of buried petroleum pipelines. The results showed that at the early stage of leakage,the resistance of contaminant is uniform lead to it uniformly transport near areas around with fast speed and gradually decreased in later stage. It would reach the surface faster if the leakage aperture is more larger and the leakage location is more nearer the surface and the surface transport characteristics are more obvious at larger maximum horizontal displacement.

Key words: petroleum pipelines, leakage aperture, leakage location, surface characteristic, transport, model, simulation
