我厂油田所辖大部分井区具有地下水位高、土壤盐碱含量高、水质矿化度高、采出液含蜡高等特点,随着运行时间的延长,埋地金属管道腐蚀穿孔严重,影响地面系统平稳运行。本文重点介绍我厂埋地金属管道使用现状、金属管道防腐检测、土壤腐蚀性、阴极保护技术的应用、防泄漏监测装置的应用、金属管道生产维护和日常运行管理等方面的情况。提出加强埋地管道管理的措施和建议,对我厂全面掌握管道运行状况、提高管理水平及降低维护成本具有重要意义。
Most of the wells under our jurisdiction have the features of high groundwater level, high content of saline-alkali soil, high salinity of water and high wax content of the produced fluid. As the running time prolongs, the corrosion and perforation of the buried metal pipe is serious and affects Ground system runs smoothly. This article focuses on the present situation of the use of buried metal pipes in our factory, the anticorrosive testing of metal pipes, the application of soil corrosion and cathodic protection, the application of anti-leakage monitoring devices, the production and maintenance of metal pipes, and daily operation and management. Proposed to strengthen the buried pipelines management measures and recommendations for our factory to fully grasp the status of the pipeline to improve management and reduce maintenance costs is of great significance.
