DOWN HOLE TROUBLE SHOOTING TECHNIQUES IN KC-1 WELL

    Graphical Abstract
    • Abstract
  • KC-1 well is located in Klasu reservoir, Kuche Depression, Tarim Basin.This is a most completed and deepest well with a complex of different pressure systems in the Basin. In its drilling process, 10 overflows, 51 lost circulation’s and other down hole accidents were encountered. As the trouble shooting measures, a series treatments such as back pressure method and engineer method well killing, regular and cement-gel lost circulation plugging operations were applied. At last, the well was drilled out successfully to its designed final depth.
