摘要
油气在开采的过程当中会带出大量的腐蚀性物质,对油管产生了非常严重的腐蚀。目前国内各大油田都采用成本较为昂贵的特种钢材来进行施工,但是长期使用这种材料所带来的经济成本较高。因此本文综述了一些目前在油管防腐蚀领域所采用的手段,如金属镀层、非金属内衬、油管内壁重防腐涂料,并分析了油管内壁重防腐涂料的防护机制。
In the process of oil and gas exploitation,a large number of corrosive substances will be brought out,causing serious corrosion to the tubing.At present,the most expensive special steel is used in domestic oil fields,but the long-term use of this material brings high economic cost.Therefore,this paper summarizes some methods currently used in the field of tubing anti-corrosion,such as metal coating,non-metal lining,heavy-duty anti-corrosion coating on the inner wall of tubing,and analyzes the protection mechanism of heavy-duty anti-corrosion coating on the inner wall of tubing.
