Mechanical Coded Sliding Sleeve

Model Specifications

JXBM

Product Overview

The mechanical coded sliding sleeve uses a key-structured staged controller to operate corresponding multi-tooth sliding-sleeve switches. Different combinations of tooth profiles provide equal-bore access and support an unlimited number of stages for large-scale fracturing. Both the sleeve and controller use fully mechanical designs for high-temperature and high-pressure conditions. The controller includes a production flow channel and uses a degradable material that fully degrades within 60 days, increasing the available flow bore while further reducing operating costs.

Detailed Introduction

Mechanical coded sliding-sleeve systems are available for the following applications:

• Fracturing systems for vertical, extended-reach, and small-diameter wells.
• Casing fracturing systems with retrievable coded sleeves for harsh operating conditions.
• Open-hole packer and mechanical coded sleeve fracturing systems for horizontal wells.
• Switchable mechanical coded fracturing systems for cemented horizontal wells.

Technical Features and Capabilities

• Supports staged fracturing in both open-hole and cemented wells while maintaining a large flow bore.
• Fracturing designs can be adjusted to cover more of the formation, increase single-well production, and improve reservoir recovery.
• Designed for horizontal wells, the identification principle provides a larger flow bore and supports more zones.
• Special materials reduce intervention work and lower operational risk.
