摘要
分析认为 ,三元复合驱油井光杆的腐蚀是以电化学腐蚀为主 ,而井液中含有的氯离子、垢物及井口密封盘根的摩擦作用加剧了光杆腐蚀 ,采用玻璃钢或高分子聚合物包敷的光杆或在杆体上布置阳极进行阴极保护可防止腐蚀发生。
The analysis indicated that the corrosion of the bare rods of the oil wells was mainly the electro-chemical corrosion, which is deteriorated by chlorine ions and fouling particles in the well liquid the friction of the packing. Binding the rod with FRP or high-molecule polymer or application of cathodic protection could prevent the corrosion.
