随着油田后期开采钻井深度不断增加,地层越来越复杂,钻进过程中出现钻具卡死在井内、无法提出已经成为常态化的工程难题,将严重制约油气田开发。但近年来,随着工程射孔技术不断创新和发展,已经形成了配套先进的工程测卡、爆炸松扣及爆炸切割技术,可以准确的从钻具卡点位置解卡提出,将损失降到最低,且具有成本低、施工方便、成功率高等优点,得到油田广泛应用。
With the increasing drilling depth in the late oilfield and more complicated strata, the drilling tool stuck in the well during the drilling process can not be put forward and has become a normalized engineering problem, which will seriously restrict the development of oil and gas fields. However, in recent years, along with the continuous innovation and development of engineering perforation technology, advanced engineering measuring cards, explosion buckling and explosion cutting technologies have been formed, which can accurately solve the problem from the location of the drill chuck and reduce the loss to Lowest, and has the advantages of low cost, convenient construction and high success rate, and is widely used in oil fields.
