连续油管加工制造的创新技术将给石油工业带来新的机遇。该技术是第四代连续油管加工工艺,即连续变量缩减(CVR)工艺。CVR工艺技术可在同一管柱上加工出不同外径、不同壁厚以及不同强度的连续油管。该技术也应用在小直径、厚壁、高压管柱的加工制造上。利用CVR技术生产的连续油管内部没有焊缝,无须使用特殊环箍或端面焊接来连接外径管柱,这是连续油管制造技术的一个重大进步。
Innovative technologies for coiled tubing manufacturing will bring new opportunities to the oil industry. The technology is the fourth generation coiled tubing process, which is a continuous variable reduction (CVR) process. CVR technology can be processed in the same pipe with different diameter, different wall thickness and different strength of the coiled tubing. The technology is also used in small diameter, thick-walled, high-pressure pipe manufacturing process. There is no weld within the coiled tubing produced using CVR technology and no need to use special hoops or end-face welds to connect OD tubing, a major advance for coiled tubing manufacturing technology.
