| 摘 要： | 针对中原油田Ｗ２２区块油井管杆腐蚀偏磨，停产待检修井增多等问题，经过检修井起出的管杆检查和油井产出水水质监测分析，认识到油井产出水水质监测分析，认识到油管杆被腐蚀偏磨，一是产出水有盐酸溶液的强腐蚀性；二是井身倾斜，形成偏磨；三是缝隙腐蚀和冲蚀综合作用等。

| Abstract: | Throughanalysis of tubing corrosion and part wear for the oil wells in W22 blocks,some reasonscaused tubing corrosion and part wear are obtained①powerful corrosivity in producedwater;②part wear due to wellbore deviation;③comprehensive action of crevice corrosionand washing etc..In this paper,some prevention measures are proposed,these are ①injectioncorrosion inhibitor in oil well;②smearing corrosion prevention material on sucker rodsurface and using high strength sucker rod;③mounting stabilizer and using rotarywellhead equipment;④changing location of sucker-rod coupling.After application of thesetechniques,useful life of oil well checking pumps are extended 220 days in W22blocks.Economic benefit is upto one million,four hundred and sixty-nine thousand yuan. |
