I. Overview

The hydraulic anchor produced by our company is the latest design on the basis of summarizing the problems existing in the construction of hydraulic anchor in common use at present. The tool adopts the design of internal limit of anchor claw, which avoids the pressure plate caused by the way of pressing plate, the screw shedding and anchor claw pulling out, and the consequence of sticking the well and so on. The double action of centralizing string and anchoring string is achieved, and the sealing effect of Packer is greatly improved. Combining with special fracturing technology to increase annulus channel area, it plays a very good role in preventing sand card from slicing fracturing in one column. The tool is advanced in design, reasonable in structure, flexible in movement, reliable in anchoring and reliable in unanchoring.

II. Technical characteristics

1. The anchor claw adopts the position-limiting structure, the hydraulic anchor can reach 30 MPA without load in the casing, and can achieve the purpose of centralizing the pipe string. The anchor claw is designed with the back-push design of the inner spring, and the anchoring is reliable and reliable, and the anchor can be unanchored quickly and reliably.

2. The anchor body has small opening and high overall strength. Straightening effect is good, safe and reliable.

3. Cooperate with fracturing technology to increase annulus channel area, delamination fracturing to prevent sandal.
