REVERSE CIRCULATION WELL CONTROL METHOD AND ITS CALCULATION IN SLIM HOLE

    Graphical Abstract
    • Abstract
  • The present regular well control method is not suitable in slim hole. A re verse circulation well control method applicable in slim hole was advanced firstly and respective calculation equations were set up. The theoretic analysis shows this method can greatly reduce casing pressure of well killing and represents a realistic well control method for slim hole.
