| 中文摘要: |
| 目的 通过对胜利油田技术检测中心2014和2015年检测的管道数据进行调研、分析，找出影响管道防腐层质量的主要因素。方法 利用灰色关联度分析方法，以差劣等级防腐层长度占管道长度的比例为参考序列，分析了运行年限、运行温度、操作压力、土壤埋深以及土壤电阻率等因素对其影响程度。结果 通过对数据的分析，发现运行温度和运行年限与防腐层质量的关联度较大，并分别分析了这两个因素对防腐层质量的影响规律。结论 油田防腐层质量的关联度排序是：工作温度>运行年限>埋深>土壤电阻率>运行压力。通过分析得出，在工作温度为50~70 ℃的管道中，防腐层的差劣等级所占的比例较大，在管道检测时应重点检测该温度范围内的管道防腐层。运行年限超过20年的管道，差劣等级的防腐层所占比例直线上升，管道防腐层老化严重，检测管道时应该缩短检测周期，及时对防腐层破损处进行合理维修。 |

| The work aims to identify main influencing factors of anticorrosive coating quality by studying and analyzing pipeline data of Technical Test Center of Shengli Oilfield detected in 2014 and 2015. With proportion of coating length with poor grades to pipe length as reference sequence, impact of factors including service life, operating temperature, operating pressure, soil depth and soil resistivity on anticorrosive coating quality were analyzed in the method of grey relation analysis. According to the data analysis, operating temperature and operating period were closely related to anticorrosive coating, the influencing law of two factors on anticorrosive coating quality was analyzed. The correlation rank of the oilfield anticorrosive coating quality is: operating temperature > operating years > burial depth > soil resistivity > operating pressure. Poor grade coating accounts for larger proportion in the pipeline with operating temperature of 50~70 ℃. Anticorrosive coating of pipelines within this temperature range shall be key detection object during pipeline detection. For pipelines having operating for more than 20 years, the poor grade coating accounts for greater proportion and pipeline coatings are seriously aged. Detection cycle shall be shortened during detection, and coating breakage shall be repaired in a timely and reasonable manner. |
