油水井的大修施工中如果措施不当,极易造成对套管的损坏,大修施工的套磨铣中如果不采取套管保护措施,会对油水井套管造成一定磨损伤害,严重的可能造成套管开窗等重大事故。在大修套磨铣施工中采用特制的具有套管保护层的套磨铣工具和新型钻杆扶正器,合理组配套磨铣施工钻具组合,并在施工中合理控制套磨铣参数,可有效的减少甚至避免对套管的磨损伤害,对大修施工中的套管保护起到了良好的作用。
Overhaul of oil and water wells in the construction if improper measures can easily cause damage to the casing overhaul construction casing mill if you do not take casing protection measures will cause some damage to the well casing oil and water may cause serious set Pipe windows and other major accidents. In the overhaul sets of milling and milling construction using a special casing with a casing protective sleeve grinding tools and a new type of drill stem centralizer, a reasonable set of supporting the construction of grinding and milling combination, and the reasonable control of sets of mill milling parameters in the construction can be effective The reduction or even avoid damage to the casing of the wear and tear, overhaul of casing protection has played a good role.
