Meilong Tube's downhole control lines are used primarily as communication conduits for hydraulically operated downhole devices in oil, gas, and water-injection wells, where durability and resistance to extreme harsh conditions are required. These lines can be custom configured for a variety of applications and downhole components.
All encapsulated materials are hydrolytically stable and are compatible with all typical well completion fluids, including high-pressure gas. The material selection is based on various criteria, including bottomhole temperature, hardness, tensile and tear strength, water absorption and gas permeability, oxidation, and abrasion and chemical resistance.
Control lines have undergone extensive development, including crush testing and high-pressure autoclave well simulation. Laboratory crush tests have demonstrated the increased loading under which encapsulated tubing can maintain functional integrity, particularly where wire-strand “bumper wires” are used.
