随着开发的深入,垦西油田K71断块油井综合含水不断上升,井筒管杆偏磨日益加剧,同时油井地层产出液矿化度高、含硫高、氯离子含量高,对杆管泵腐蚀性强。通过对K71断块油井井筒偏磨腐蚀状况调查研究分析,结合生产实际提出了从源头进行治理,采取套管加药防腐治理工艺等相应的综合配套防治技术,取得了良好的防偏磨腐蚀效果,也为今后的偏磨腐蚀治理提供了参考。 With the deepening of development, comprehensive water cut in well K71 of Kuixi Oilfield is increasing continuously, and partial eccentricity of wellbore pipe rod is aggravated. Meanwhile, the production fluid of oil well formation has high salinity, high sulfur content and high chloride ion content. Corrosive. Based on the investigation and analysis of borehole abrasion and corrosion of K71 fault block oil well, combined with the actual production, put forward from the source to carry out management, take casing anti-corrosion treatment technology and other integrated supportive prevention and control technology, and achieved good anti-wear corrosion , But also for the partial wear and tear corrosion governance provides a reference.
