锥形连续管技术

Tapered Coiled-Tubing Technology

锥形连续管技术是近几年从连续管应用中发展起来的一项创新技术,该技术能使连续管具有变外径、变壁厚和不同的强度等级,减小整个管柱在长度上的张力,可以满足深井、超深井作业深度,提高连续管使用寿命。介绍了国外锥形连续管系统及其加工制造工艺。

Tapered coiled-tubing technology is one kind of technology, which develops coiled-tubing technology in recent years in practical application, this innovation technology has brought the new opportunity for the coiled-tubing development. This kind of technical ability with vital significance that features capability of variable outer diameter, variable wall thickness and varying strength levels to reduce the tension along the string length, may satisfy the deep well, the extradeep well work depth, enhances manages the service life of coiled-tubing. A briefly the overseas development tapered coiled-tubing system and the tapered coiled-tubing manufacturing technology is introduced in this article.
