摘要： Apparatus for drilling and lining a wellbore is described herein. A method of drilling and lining a wellbore is also described herein. A liner hanger is provided, secured in use on a liner. The liner hanger is operable selectively to be set and unset. The liner hanger is adapted to support the liner within an existing casing when set and to release the liner from the casing when unset. A liner hanger setting tool is provided, secured in use on a drill string. The liner hanger setting tool is actuatable selectively to set and unset the liner hanger. The liner hanger setting tool is operable selectively to be activated and deactivated. The liner hanger setting tool is adapted to attach to the liner and/or liner hanger when activated, to support the liner, and to release from the liner and/or liner hanger when deactivated. The method comprises the following steps: (a) setting the liner hanger by actuating the liner hanger setting tool; (b) deactivating the liner hanger setting tool; (c) extending the borehole using the drill string; (d) returning the drill string to its position at the setting step or the deactivating step; (e) activating the liner hanger setting tool; (f) unsetting the liner hanger by actuating the liner hanger setting tool; and (g) lowering the liner down the extended borehole on the drill string.
