摘要
为实现内检测数据的系统管理与综合分析应用,以3次内检测数据为例,在统一的数据标准模式下,运用软件算法+人工干预的方法对齐内检测数据中的阀门、弯头、焊缝、缺陷等要素,管道主要特征对齐比例达到99%以上。分析数据对齐过程中的影响因素,同时基于多源数据的叠加、展示条件,开展数据可靠性分析、腐蚀发展评价等工作。
In order to realize the systematic management and comprehensive analysis and application of the MFL data,taking the three-time MFL data as an example,under the unified data standard mode,using software algorithm and manual intervention method to align the valves,elbows,welds and defects in the MFL data,the alignment proportion of the main features of the pipeline reached more than 99%.The influencing factors in the process of data alignment were analyzed.At the same time,data reliability analysis and corrosion development evaluation were carried out based on the overlay and display conditions of multi-source data.
