Hydraulic Tubing Anchor YAGT

Application

The Hydraulic Tubing Anchor YAGT is designed to fix body of screw downhole motor during its operation. It eliminates axial throw and turn under influence of counter torque. The anchor is used in an assembly with downhole motor and internal hydraulic pipe cutter TVG. It can also be used for other technological operations. The assembly is lowered into the well on small-size pipes or from coiled tubing units.

Design

The Hydraulic Tubing Anchor consists of body, hold-down slips pressed by springs, which are fixed by planks by means of screws and sealing elements.
The Anchor is set above the downhole motor. Under pressure of increasing drilling fluid rate, slips move out of body. After that slips are fixed on the internal pipe wall. When circulation goes down, pressure decreases and slips move back into body (transport position).
