Fracturing Hanger Packer Permanent Casing Hanger Up and Down Dual Slips-Well Completion
ADD TO WISHLIST
Overview

The hydraulic-set casing packer is a hydraulic permanent packer designed for the open-hole fracturing packer system, designed to hang the lower completion pipe in a string. The principle is to press inside the tubing, the thrust produced by the piston acts on the slips, and squeeze the packing element through the upper and lower cones. The upper and lower slips are broken and embedded in the inner wall of the casing, and the packing element expands and seals to complete the setting. At the same time, the locking ring inside the packer locks the setting force and maintains the setting of slips and packing element.

Talk with anton expert
Two opposed sets of full-circle, full-strength slips ensure packer will remain properly set
Expandable back ring can reduce the loss of element being extruded
Setting does not require rotation or reciprocation
Double-pistons reduce setting pressure.
Large hole ID
Different metal parts and element are designed to meet specific downhole conditions
Ratchet locking mechanism maintains setting force
Idea for HTHP application
