发明名称 Method for installing wellbore string devices
摘要 A method for securing a wellbore string device to a wellbore liner tubular employs a swelling elastomer to frictionally grip a gap between the wellbore string device and the liner tubular. The swelling elastomer is positioned between the wellbore string device and the wellbore liner tubular, then activated to cause it to swell to engage the wellbore string device with the wellbore liner tubular. The wellbore string device may be a centralizer, a wear band or a torque ring.
