摘要
伊拉克M油田部分油井因含水率上升而不能自喷生产,在进行射孔作业或更换生产管柱类型前,需将原完井管柱中下入的永久式封隔器捞出。为顺利打捞出高强度材质的永久式封隔器,采取了先打捞封隔器顶部接头,然后再实施套铣打捞的办法。实践证明,这种处理方式可以大大提高处理封隔器的作业效率。
In Iraq M oilfield,due to the rising high water-cut,some wells can′t produce naturally;before perforation or replacement of the production string,the permanent original packer should be fished out.In order to fish out the high strength permanent packer smoothly,the top sub of packer should be retrieved first then milling and fishing the left part.Practice has proven that this method can improve the efficiency significantly and is worthy to promote.
