Assignee:
Dresser Industries, Inc. - Dallas TX
International Classification:
E21B 2306
E21B 33129
E21B 3314
E21B 33129
E21B 3314
US Classification:
166142
Abstract:
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 linear and the packer assembly within the well bore.
Setting Tool For Mechanical Packer
US Patent:
4830103, May 16, 1989
Filed:
Apr 12, 1988
Appl. No.:
7/180488
Inventors:
Henry W. Blackwell - Venus TX

Rodger D. Lacy - Midland TX
Assignee:
Dresser Industries, Inc. - Dallas TX
International Classification:
E21B 2306
US Classification:
166387
Abstract:
A packer setting tool is disclosed for providing quick and reliable release thereof from a well casing packer. The setting tool is adapted for lowering the packer assembly within the casing. The setting tool is rotated by a drill string to release an upper set of packer assembly slips into engagement with the well casing. The packer setting tool is then lifted, thereby deploying a rubber sealing boot and setting the upper and a lower set of slips into permanent engagement with the casing. The packer setting tool is then again rotated, whereupon a shear connection is released and the setting tool can be removed from the packer and out of the well bore.
