TERTIARY WELL CONTROL TECHNOLOGY OF WELL DINA-2

    Graphical Abstract
    • Abstract
  • During the drilling of well Dina-2, serious blowout and fire took place when drilling into the high-pressured rich gas zone. The emergency plan after the loss of well control, and the whole operation process from reverse circulation killing, cementing through annular, cutting the drill pipe, to installing the BOP stack, further killing and installing the Christmas tree are described. This set of tertiary well control technology is efficient for the high-pressured gas well, and it provides some valuable experience for dealing with such emergency conditions.
