Description

Introduction
The packer uses a hydraulic expansion packer. The lower part of the packer is connected with the setting ball seat, the short segment screen is busy blocked, the pressure is set, and the built-in single flow valve is opened until completely set under a certain pressure. It has the advantages of simple operation and reliable performance, and can be used in the stratified water injection process in the oilfield, and it can also be used in the construction technology such as stratified acidizing fracturing and stratified plugging.

Second, performance characteristics

1. The packer adopts hydraulic setting in the structure and lifts the seal;

2, large pressure difference, strong adaptability, small size packer can seal large diameter hole, and the hole rules are not strict requirements;

3. Long sealing section, reliable sealing pressure difference, long service life, fast unlocking speed;

4. The packer is designed to resist water stroke, avoid setting accidents in the middle of the running process, and improve the running safety in horizontal well construction.
