The utility model relates to a hydraulic oil tubing anchor, which is used in a well with an oil hoisting bar during oil field development, belonging to a well device for preventing creepage of the oil tube during oil pumping. In the prior art, the oil tubing anchors are not stable enough for the oil tube, and the anchors are difficult to relieve later. The utility model provides the new hydraulic oil tubing anchor for hydraulic anchorage and hydraulic unanchorage which is of reliability and simple operation. The principle is that: the tubing anchor is arranged at the oil tube; when the tubing anchor goes down to certain place, a lock pin is cut off when pressure is increased in the oil tube, and a piston goes down, so that a lock tile is anchored with inner wall of the tube case. When the hydraulic anchorage is unlocked, the pressure is still increased, an unlock pin is cut off, the piston case is propped up, so that the lock tile is taken back and the anchor is unlocked.
