Development and Trend of Coiled Tubing

The development and application of coiled tubing are summarized from the aspects of coiled tubing materials, manufacturing technology and operation technology, and the technical development trend of TMCP ultra-high strength coiled tubing, quenched and tempered coiled tubing and anti-corrosion coiled tubing are analyzed. The research shows that the prospect of coiled tubing is good, and with the in-depth exploitation of oil and gas and the increasing complexity of well conditions, higher requirements are put forward for the specification and performance of coiled tubing. At present, coiled tubing with high strength and low alloy steel series are mainly formed, and there are many series development directions such as high corrosion resistant alloy, composite material and quenching and tempering steel. The coiled tubing specification will develop in the direction of larger outer diameter and length, and the performance will develop in the direction of higher strength, longer fatigue life and better corrosion resistance. At the same time, more attention will be paid to the economy and manufacture of products in the future.
