适应小井眼的反循环井控方法及其计算

REVERSE CIRCULATION WELL CONTROL METHOD AND ITS CALCULATION IN SLIM HOLE

    摘要
  • 摘要: 随着小井眼钻井技术的逐渐推广应用,小井眼的并控问题将会越来越突出,目前常规的压井方法很难解决小开眼面临的井控问题。文中首次提出适应小井眼的反循环并控方法并给出了相应的计算公式。理论分析表明,反循环并控方法可明显降低压井套压,是一种适应小井眼的理想的井控方法。

     

    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.
