    • A method for sealing a hole in a tubular in a wellbore comprising: (A) locating the tubular patch adjacent the hole; (B) (i) plastically expanding a first portion of the tubular patch above the hole into annular sealing engagement with the tubular to form a first annular seal and (ii) plastically expanding a second portion of the tubular patch below the hole in the tubular into annular sealing engagement with the tubular or the open hole to form a second annular seal thereby sealing the hole in the tubular. The patch may be a corrugated tube prior to expansion in order to pass through restrictions and may have a section with an increased wall thickness including a resilient seal.
    • 一种用于密封井眼中的管状物中的孔的方法,包括:(A)将所述管状贴片邻近所述孔定位; (B)(i)将孔上方的管状贴片的第一部分塑性膨胀成与管状物形成环形密封接合,以形成第一环形密封,并且(ii)将管状贴片的第二部分在管状物的孔下方塑性膨胀 与管状物或露出孔形成环形密封接合以形成第二环形密封件,从而密封管状物中的孔。 在膨胀之前,补片可以是波纹管,以便通过限制,并且可以具有包括弹性密封件的增加的壁厚的部分。
