| 中文摘要: |
| 针对油气田集输管道的内腐蚀问题，分别介绍了耐蚀材料、衬里技术、涂镀层技术与药剂防腐技术等管道内防腐技术及其现场应用效果，指出了耐蚀金属材料防腐效果显著，但存在经济效益差的缺点。为降低成本，选用双金属复合管替代耐蚀金属材料，但其焊缝位置腐蚀失效频发，成为制约其应用的薄弱环节。耐蚀非金属材料防腐效果显著，但耐高温性能与力学性能较差，受温度、压力与CO2、H2S、固体颗粒等介质成分的影响，衬里技术与涂镀层技术的应用范围受到限制。药剂防腐技术的防护效果与药剂类型、加药工艺密切相关，需要根据腐蚀工况监测结果进行实时调整。针对上述内防腐技术存在的问题，提出了未来内防腐技术的发展方向为改进现有内防腐技术存在的不足，提升其防护效果。同时，应开发防腐效果显著、经济成本低、施工简便、易于推广应用的防腐材料与防腐工艺技术。 |
| 英文摘要: |
| In view of internal corrosion problem of oil & gas transportation pipeline, the internal corrosion technology for oil and gas pipeline and their applied result were introduced, including corrosion resistant material, lining technology, coating technology and corrosion inhibitor injection technology. It was indicated that corrosion resistant metal material was featured with good corrosion resistance but has deficiency in economic performance. To reduce the production cost, double-metal composite pipe was selected as substitute for corrosion resistant metal material. But the corrosion problem occurred in the welding seam. The welding seam became the weak link which limited its application. Corrosion resistant non-metal material worked wonderfully in preventing corrosion, but its mechanical property and the capability of bearing high heat was poor. The scope of lining technology and internal coating technology were limited as a result of temperature, pressure and the composition of corrosive medium, such as CO2, H2S and solid particles. The corrosion resistance result of corrosion inhibitor injection technology was closely identified with corrosion inhibitor and dosing process. The corrosion inhibitor and dosing process should be changed according to actual working condition. In allusion to the existing problem of internal corrosion technologies above, the development trend of internal corrosion technology of pipeline was proposed. It included two aspects: overcoming the disadvantages of exiting internal corrosion technology and improving the corrosion resistance. Meanwhile, it is required to develop new anti-corrosion materials and internal corrosion technology which had the advantages of remarkable corrosion resistance result, less production cost, convenient operation and application and extension. |
