| 摘 要： | 可取式液压双向锚定封隔器是目前结构最复杂、性能最好的一种封隔器。这种封隔器设计中应注意的问题是：（1）锚定方式选择；（2）坐封后的承压平衡；（3）解封方式选择；（4）双锥体结构锚定机构的下锥体脱卡；（5）锁紧机构的设计与选择。从我国机械加工能力和使用可靠性方面考虑，建议优先选用单面螺纹步进锁紧机构。提出了单卡瓦双锥体双向锚定、承压平衡、单面螺纹步进锁紧及下锥体主动力脱卡的设计思路和方法。

| Abstract: | In the design of the hydraulic dual-anchor retrievable packer, the following should be taken into consideration: (1)selection of anchoring mode; (2) pressure balancing after the setting of the packer; (3)selection of the mode of packer releasing; (4)slipping-off of the lower taper of the double-taper anchoring mechanism; (5) design and selection of the lorking mechanism. And it is recommended to adopt single-slip double-taper dual anchoring, pressure balancing, singleside thread step-by-step locking and the lower taper slipping-off by the main power, |
