| 中文摘要: |
| 油井套管外腐蚀是套管失效的最主要形式,严重制约了油田的作业和开发。 阴极保护技术已广泛应用于油井套管系统的防腐蚀保护。 实践证明,该技术是目前使用最广泛、最有效的油井套管防腐蚀技术。 然而,基于脉冲电流的阴极保护技术在油井套管中还没有相关应用。 理论研究和模拟实验证明,脉冲电流阴极保护技术具有电流分布更均匀,总电流需求更低,保护深度更深,耗能更低等诸多优点。 通过介绍脉冲电流阴极保护技术的历史、研究进展、应用条件等,对油井套管阴极保护技术进行了综述;探讨了油井套管脉冲电流阴极保护基本参数的影响规律;总结了对该技术保护效果的评价,并对其保护效果进行了展望。 |

| Objective Corrosion in the oil well casing is the main form of casing failure, which severely restrict the operation and development of oil fields. Cathodic protection technology has been widely used in oil well casing corrosion protection systems, and the practice proved that the technology is currently the most widely used and most effective oil well casing corrosion protection technology. However, there is so far no related application of cathodic protection technology based on pulse current in oil well casing. Theoretical research and simulation experiments show that pulse current cathodic protection technology has a number of advantages such as more uniform distribution of current, lower total current demand, deeper protection depth, and lower energy consumption. In this paper, through the introduction of the history, research progress and application conditions of pulse current cathodic protection technology, the well casing cathodic protection technologies were reviewed; the influencing law of basic parameters of oil well casing pulse current cathodic protection was discussed , the protective effects of the technique were summarized, and the protective effect was discussed. |
