octg Anti-Corrosive tubing and casing
The technique feature
The Nanoscale-Titanlum-containing Compound Coated Tubing(NTCCT) from our company are characterized with wear proof,excellent performance of anti-corrrosive,great tensile strength, and shock resistant. NTCCTC has significantly extend the running life of the tubing, decreased the cost of oil production.This technique has been patent protected.In the downhole condition, the running life of NTCCT is 3-5 times of the uncoated tubing, and more than 5 times on the surface condition, this result has already testified by the oilfield experiment.
