On February 19, 2022, Hay Think learned from SXYG Petroleum Steel Pipe Technology Corporation that China's first 9,500-meter-long ultra-high-strength variable-wall-thickness coiled tubing was successfully rolled off the production line, which once again refreshed China's single-reel length and wall thickness span maximum ultra-high-strength continuous The tube record marks a new leap forward in China's coiled tube manufacturing technology.
In recent years, with the continuous increase of China's deep oil and gas exploration and development, ultra-deep wells, ultra-long horizontal wells, and ultra-high pressure operations have put forward higher requirements for coiled tubing strength and length. SXYG continues to build coiled tubing equipment to meet the needs of oil and gas exploration. Develop special requirements for pipe equipment.
It is understood that in this production process, SXYG solved the problems caused by 8500-meter-long steel strip coiling and ultra-high strength on forming and sizing equipment, and overcome the large span of wall thickness range and small diameter-to-thickness ratio. Due to the difficulties caused by the process, after nearly 7 hours of continuous and stable production, China's first coiled tube with a diameter of 44.45 mm, a wall thickness of 3.68-4.8 mm, and an ultra-high-strength variable wall thickness was created.
After testing, the performance of the product meets the standard requirements.
As the top product of the current coiled pipe, the ultra-high-strength variable-wall-thickness coiled tubing has ultra-high pipe strength, superior collapse resistance and torsion resistance. It is an 'ideal product' for the development of deep oil and gas resources and unconventional oil and gas such as shale gas.
Relying on the technology and talent advantages of the national steel pipe research and development center and the pipe-making technology experienced for more than ten years, SXYG continues to increase its scientific and technological research and development efforts. Corrosion-resistant alloy coiled tubing such as 18 chrome, as well as high-end products such as non-metallic coiled tubing and multi-channel coiled tubing.
While satisfying the exploration and development of major oil and gas fields, the products have been exported to more than 10 countries and regions such as Russia, the United Arab Emirates and Ukraine.
