摘要
KUR103井为KK油田主力注水井,由于转注时未采取井下保护套管措施,油层套管固井水泥返高以上出现大井段穿孔,技术套管也存在穿孔,井口环形钢板脱焊,井口可自由晃动,并且存在严重漏失。在本井的复杂井筒再造固井过程中,采取合理的施工工艺,解决了该井的复杂问题,不仅加固了井口套管受损部位,再造合格井筒,在维持先前的平均注水压力下日注水量提高了100m3,取得了很好效果。对同类井的修套固井施工具有参考意义。
KUR103 Well is the main injection well of the petroleum International Azerbaijan KK oilfield.Because protect casing measures is not taken while injecting,a large sections over cement of oil formation casing is perforated,technical casings also existed problems,wellhead is free to sway as wellhead annular plate looses soldering,and mud liquid leakages serious.During re-cementing recycling process of this complex bore hole,a reasonable construction technology is taken to solve the complex problems.Not only the wellhead casing damaged parts fixed to recreate a qualified bore hole,but also the amount of water increases on 100m3 maintaining the previous average injection pressure,and good result is achieved which has a reference value for similar repairing case and cementing well.
