Description

Y-shaped hydraulic anchor for oil well operation

Technical Field

The utility model relates to a hydraulic anchor technical field specifically is a Y type hydraulic anchor for oil well operation.

Background

The hydraulic anchor is pressed through the inside of the oil pipe, anchor claws evenly distributed on the circumferential surface of the hydraulic anchor body extend outwards under the action of hydraulic pressure generated by internal and external pressure difference, anchor teeth on the outer surface of the anchor claws are embedded into the wall of the sleeve, the tool is limited from moving up and down, and anchoring is realized. After the difference between the internal pressure and the external pressure of the tool is eliminated, the anchor fluke is reset under the elastic force action of the internal spring between the baffle and the anchor fluke, and the anchoring is released.

Traditional hydraulic anchor appearance is cylindrical for the oil gas well during operation of well sand deposit sand card situation appears easily when the instrument upwards moves, influences the removal of work piece, increases the difficulty of construction, for this reason, we provide a Y type hydraulic anchor for oil well operation.
