RETRIEVABLE HYDRAULIC-SET ESP PACKER

INTRODUCTION

Retrievable hydraulic-set ESP packer is used for ESP completion. The inner clip with spring load is used for packer to set lock framework. The lower mechanical outer clip can keep the packer in the state of setting, and it can endure the force acted on the Packer upward and downward. The seal elastomeric cylinder can ensure that the packer is well set under high pressure or low pressure and in irregular casing. Release method of Packer is divided into pulling the tubing string upward and hydraulic release.

FEATURES

◎ A pack-off power cable is provided for thread connections on the top of Packer;

◎ Additional bores can be attached to gas vent valve, chemical-injection lines, hydraulic pressure   control lines and wellbore monitoring devices through the packer;

◎ Double-seal elements have the same or different hardness;

◎ Bi-directional slips with surface heat treatment can endure the force acted on the Packer upward and downward;

◎ The upper pressure-actuated hydraulic slips can make the packer withstand higher pressure differentials from downhole;

◎ Setting and release force can be adjusted by Shear screws.

BENEFITS

◎ Low setting pressure;

◎ Release by pull straight or hydraulic release;

◎ Allows varied setting pressure with varied numbers of shear screws;

◎ Allows adjust setting and release force by adjustment of shear screw number;

◎ Allow adjust release force on site;

◎ Efficiently reduce the overall costs of submersible pump completions.
