摘要： 对青海油田花土沟地区部分在役管道进行了土壤腐蚀性检测,其主要指标包括电阻率、自然腐蚀电位、氧化还原电位、pH、水质量分数、盐质量分数、氯离子质量分数、土壤腐蚀速率。结合灰色关联、模糊评价、改进层次分析三种理论,建立相应的综合评价模型,运用该油田花土沟地区的15组实测数据,详细阐明了该模型的具体应用情况,并对通过模型得出的评价结果与原评价结果进行了对比。对比结果可知,此模型的评价结果比原评价结果更接近实际情况。

关键词: 灰色关联, 改进层次分析法, 模糊理论, 综合评价模型, 腐蚀等级

Abstract: The main index factors of the soil corrosion detection， for the section of pipeline in service in Qinghai Oilfield Huatugou, included resistivity, natural corrosion potential, redox potential, pH, moisture content, salt content, chloride ion content and soil corrosion rate. Combined with three theories, gray correlation, fuzzy evaluation, and improved AHP, the appropriate comprehensive evaluation model was established, the 15point set of measured data was used in Huatugou areas of this field to clarify its application of this method, and evaluation results reached by the comparison model with the original evaluation results were contrasted. The results of this evaluation model showed that the evaluation results was closer to reality than the original evaluation results.

Key words: Gray association, Improved analytic hierarchy process, Fuzzy theory, Comprehensive evaluation model corrosion grade, Corrosion grade
