小径管道检测定位关键技术探讨

A review on small-diameter pipeline inspection gauge localization techniques

管道系统在石油、天然气和水等资源的运输中扮演着十分重要的角色。然而,埋在地下的管道经常会被自然腐蚀、人为破坏、长期地壳运动等原因损坏。因此,管道完整性管理就极其的重要。中对现有的小径管道(直径D<300 mm)定位方法进行了讨论,同时,对主要典型定位方法的关键技术和存在的问题进行了详细的讨论和分析。最后,就小径管道检测装置定位问题面临的挑战和潜在的研究方向进行了总结分析。

The pipeline system plays an important role in oil/gas/water transportation.However,the buried pipeline is sometimes leaked by the corrosion,human destruction,long-term Earth movement and so on.Therefore,the pipeline integrated management(PIM)is extremely important.In this paper,the existing small-diameter pipeline(D<300mm)localization methods is reuiewed.In addition,the problem formulation,major techniques of typical localization methods are surveyed and analyzed with details.Finally,the challenges and the potential research directions of the small-diameter PIG localization problems are also analyzed.
