Oilfield Downhole Tool Torque Anchor Tubing Anchor For Progressive Cavity Pump
Description of Torque Anchor:
Torque anchor is used to take the reactive torque given by the friction created between the rotor and stator of the pump with progressive cavities, to prevent the tubing from unscrewing. It is mounted under or just above the pump. It uses the principle of a mandrel with two slips (one floating,one stationary) camming in opposite directions anchoring the tubing string to the inner casing wall.
The Extra Bypass is a standard feature of the Torque Anchor that offers a larger area around the torque anchor for gas bypass and to discourage sand bridging.
By adding a set of drag blocks, the damaging harmonics are absorbed before reaching the anchor blocks that are engaged onto the casing.
