Recently, the 2,900 - meter φ88.9×5.2mm (φ3.5″×0.204″) large - diameter thick - wall quenched and tempered coiled tubing produced by Shinda Creative, a subsidiary of Huatong Wires and Cables Group, was successfully delivered. This milestone signifies that our company has achieved a crucial technological breakthrough in the field of high - end oil and gas extraction equipment manufacturing, injecting new impetus into the efficient development of domestic oil and gas fields and the guarantee of energy security.
Quenched and tempered coiled tubing is a high - end coiled tubing product featuring high strength, high toughness, and a more uniform structure. Its fatigue life can exceed 1.5 times that of conventional coiled tubing. Through in - depth research on heat treatment to overcome performance bottlenecks, this type of coiled tubing is ultra - long - lasting and suitable for harsh working conditions such as deep wells, ultra - deep wells, and extended - reach horizontal wells in oil and gas fields, thereby reducing costs and enhancing efficiency in oil and gas extraction.
As domestic oil and gas exploration continues to extend into ultra - deep, deep - water, and high - pressure complex working conditions, the quenched and tempered large - diameter thick - wall coiled tubing that has been successfully rolled off the production line this time achieves a perfect balance between high strength and high toughness through the independently developed quenching and tempering heat treatment process in the whole process. The product completely overcomes the technical contradiction of traditional coiled tubing, which is "insufficient strength for large - diameter tubing and reduced flexibility with increased wall thickness", truly realizing the unity of high performance in large sizes.
In the field of coiled tubing manufacturing, when the three factors of large diameter, thick wall, and high steel grade form a superposition effect, what is tested is no longer the single - point ability of a single process, but the collaborative accuracy of the entire production line from raw material pretreatment, continuous forming, online weld monitoring to quenching and tempering heat treatment. This is by no means a simple upgrade of product specifications, but a systematic drill of the entire manufacturing system from equipment load, process control to the closed - loop control ability of the whole process. The successfully rolled - off quenched and tempered large - diameter thick - wall coiled tubing represents a further upgrade of the load - bearing capacity of production equipment and a further refinement of the technology of the entire process chain.
Currently, the domestic oil and gas industry is at a crucial stage of "increasing reserves and production, digital and intelligent upgrading, and green transformation". The demand for high - end downhole equipment in incremental fields such as shale gas, deep - layer oil and gas, and offshore oil and gas continues to rise. In the future, we will continue to focus on high - end materials and advanced forming processes, promote the implementation of more high - performance and customized tubing products, and comprehensively assist the domestic oil and gas industry to upgrade in the direction of higher efficiency, lower cost, and greater safety and environmental protection through technological breakthroughs at the manufacturing end, thus laying a solid equipment foundation for national energy security.
Meanwhile, Huatong Cable Group is also a professional manufacturer of ESP cables, and marine&offshore cables. These cables are highly suitable for use in highly corrosive environments within the oil and gas industry, ensuring stable workflow operations.
