摘要: 长输油气管道多轮内检测数据的挖掘和综合应用是管道完整性管理的重要组成部分。为了开展数据的对齐和比对,整合了内检测数据的形式和内容,梳理了对齐和比对的实施流程,研究和分析了对齐和比对的内容和方法,从而掌握了管道基础信息、缺陷的数量和增长情况、管道位置的变化等重要信息,有望为管道运行单位制定管道管理计划和风险管控措施提供科学依据。Abstract: The in-depth research and comprehensive application of multiple in-line inspection data for long-distance oil and gas pipelines is an important part of pipeline integrity management. In order to carry out data alignment and comparison, the form and content of in-line inspection data have been integrated, the implementation process of alignment and comparison has been sorted out, and the content and methods of alignment and comparison have been studied and analyzed, so as to master important information such as the basic information of pipeline, number and growth of defects, change of pipe position, and so on. And the above-mentioned results are then used to guide pipeline operators to formulate pipeline management plans and risk control measures to provide scientific basis.
