A hydraulic packer typically is set using hydraulic pressure applied through the tubing string rather than mechanical force applied by manipulating the tubing string.
一般地，经油管柱施加液压压力而不是由操纵油管柱施加机械力使封隔器坐封。
This packer is characterized by being set by hydraulic pressure, being released by lifting up the string, being anchored by self-locking and being locked by circlip stepping.
该封隔器具有液压坐封、液压上提解封、自锁锚定、卡簧步进锁定等特点。
