Liner and drill pipe assembly
This patent describes a method of cementing a linear in a well bore. It comprises: making up sections of pipe to form a liner disposed in a well bore to a desired length of liner, supporting the desired length of liner at the earth's surface while making up sections of drill pipe to form a desired string of drill pip co-axially disposed within the desired length of liner where the desired string of drill pipe has a polished mandrel and a sealing bore receptacle at its lower end when the polished mandrel is in position for sealing reception in the sealing bore receptacle, attaching a setting tool assembly to the desired string of drill pipe and attaching a liner hanger assembly with liner hanger slips to the desired length of liner; releasing the liner at the earth's surface and making up a supporting string of drill pipe attached to the setting tool assembly for lowering the co-axially disposed (telescoped) desired length of liner and string of drill pipe through the well bore hanging the liner in the well bore with liner hanger slips; pumping a volume of cement slurry through the supporting string of drill pipe; and upon the trailing end of the volume of cement slurry reaching the lower end of the desired string of drill pipe, opening the interior of the desired string of drill pipe to the interior of the liner at a location above the sealing bore receptacle.
