油水井阴极保护技术在现河采油厂的应用

Application of Tubing Cathodic Protection Technology in Xianhe Oil Production Plant

针对现河采油厂油水井井下油管内外壁、丝扣、节箍及抽油杆腐蚀严重,导致油井生产周期缩短的现状,开展了油管阴极保护技术实验。结果表明,该技术能有效减缓井下管杆的腐蚀速度,延长油水井的生产周期。

Aiming the severe corrosion at downhole string inner-outer surface,screw,node and pumping rod of oil-water well downhole string curtailed production period of well in Xianhe oil production plant, the experiments of tubing cathodic protection technology was researched. As a result, this technology can slow down corrosion speed of downhole string and extend production period effectively.
