摘　　要：分析了影响FH型静液压封隔器解封力的因素，认为该型封隔器的解封力与其工作时的承压、坐封启动压差、泵抽汲及温度等因素有关。介绍了其解封力的具体计算方法，为该型封隔器的解封剪环规格的选择提供了理论依据。在满足使用的条件下，应尽量选用小规格的剪环，以减小封隔器的解封力。在计算其它封隔器的解封力时，本文介绍的计算方法可作为参考。The factors influencing the releasing force of Model FH hydrostatic packer are analyzed, and it is indicated that the releasing force is related to the working pressure, setting pressare, pumping conditions and temperature. The method for calculating the releasing force is presented, providing a basis for selecting the size of the releasing shear ring. Under the condition of satisfying the operating requirements, small sized shear rings should be selected to decare the releasing force. The above-mentioned method can be taken as a reference for calculating the releasing force of other kinds of pakkers.
