The world's highest strength coiled tubing was successfully developed

Make the "oil and gas hand" of the universal operating machine stronger

On August 9th, the reporter learned from Baoji Petroleum Steel Pipe Co.
, Ltd.
that the CT150 coiled tubing independently developed by the company was successfully trial-produced and planned to go down well for verification
.
This is the coiled tubing with the highest level of strength in the world at present, marking China's leading position in this field in the world

Bi Zongyue, former deputy director of the National Oil and Gas Pipeline Engineering Technology Research Center and chief technical expert of Baoji Steel Pipe Company, told reporters that with the increase in shale oil and gas exploration and development, high-pressure/ultra-high pressure and ultra-long horizontal well workover, drilling, and staged fracturing The requirements for the strength and toughness of coiled tubing are getting higher and higher for other operations
.
Through joint research with steel and metallurgical enterprises, Baoji Steel Pipe has overcome the bottleneck of raw materials and broke through the core technology of pipe manufacturing.

As the largest manufacturer of oil and gas tubing in China, Baoji Steel Pipe Co.
, Ltd.
relies on the advantages of the National Oil and Gas Tubing Research Center to continuously innovate and tackle key problems.
It has broken through the 5 core technologies of coiled tubing and built the world's third and first coiled tubing in Asia more than 10 years ago.
The production line has made great contributions to complex oil and gas exploration and development, making China the second country after the United States that has mastered the core technology of coiled tubing and has industrialized production
.
The company's coiled tubing has been identified as a national key new product, and it has become a technological weapon for China's petroleum equipment, fully replacing imports

It is understood that coiled tubing is a high-end petroleum pipe material with no connecting threads and a single length of up to tens of thousands of meters.
It is mainly used for workover, logging, drilling, and completion.

Last year, Baoji Steel Pipe developed a new type of ultra-high strength CT130 coiled tubing, which has the characteristics of high internal and external pressure resistance, strong rigidity, high torque, and long cyclic fatigue life.

Bi Zongyue said that in the next step they will research and develop high-temperature resistant, reinforced non-metallic composite pipes and intelligent coiled tubing to make downhole oil production, surface collection and downhole transmission systems smarter and smarter
