Zusammenfassung:	METHOD FOR INSTALLING A LINER WITHIN A WELL BORE A packer setting tool, a packer assembly and an attached liner assembly are lowered into a well bore at a desired depth to fix the liner therein. Cement is pumped down a tubing string, through the packer, the lining, check valves and forced upwardly in the annulus of the well bore. The pumped cement is followed by a non-setting liquid to clear the internal tubular structure. The packer assembly is then set in the wet cement of the annulus to provide an additional fluid seal in the well bore. The packer setting tool is released and the cement is allowed to harden and fix the liner and the packer assembly within the well bore'
