油气田在役管道高后果区识别与完整性评价方法

根据油气管道建设与管理的相关标准与规范或导则,针对目前油气田在役管道,明确了其高后果区识别的划分及其在不同标准中的差异以及识别的原则和时间间隔,分别介绍了在管道的相关数据采集的基础上开展地质灾害和第三方破坏造成的管道风险评价方法,管道内外腐蚀的直接评价以及包括剩余强度、剩余寿命和材料在内的管道适用性评价方法,同时给出了这些评价工作所涉及到的相关内容项,对油田管道的完整性管理具有重要的指导作用和应用价值。

Method for High-consequence Area Identification and Integrity Evaluation of Oil and Gas Pipelines in Service

According to relevant standards and norms or guidelines on construction and management of oil and gas pipelines, the classification of high-consequence areas and their differences in different standards, as well as the principles and time intervals for identification, were presented for the current pipelines in oil and gas fields. Methods for evaluating pipeline risks caused by geological disasters and third-party damage on the basis of relevant data collection of pipelines, direct evaluation of internal and external corrosion of pipelines, and fitness-for-service evaluation of pipeline applicability including residual strength, remaining life and materials were introduced and relevant content items involved in these evaluation work were given. They have important guiding role and application value for integrity management of oil field pipelines.
