发明名称 HYDRAULIC RUNNING AND SETTING TOOL FOR WELL PACKERS
摘要 <p>A hydraulic running and setting tool for a well packer including an annular cylinder body having a top sub for connection with a tubing handling string, a longitudinal operator tube releasably secured at a first upper end in the top sub, a first locking collet assembly for releasably coupling with packer body including a collet connected with the top sub and a collet locking surface along the second end of the operator tube, an annular piston in the cylinder body, and a second locking collet assembly releasably connected with the piston for operating a packer setting sleeve. Shear pins in the running tool isolated from weight forces applied to the running tool by the packer control the setting sequence while the packer remains fully coupled by the first collet assembly. The release of the first locking collet assembly is a distinct separate step from the packer setting sequence permitting manipulation of the packer to check if properly set and for pressure testing while the running tool remains coupled with the packer.</p>
