Casing running in systerm(CRT) is a new technology of running in casing, this technology can exert all the advantages of top-drive drilling, enabling the casing string to be rotated, lifted, and recycled mud at the same time when running in casing, thus ensuring that the casing can be normally running into the bottom of the well. Improve the success rate, safety and efficiency of casing running observably, it has great advantages in running casing at oilfield, especially in extended reach well and horizontal well which are difficult to run casing.  

Main technical feature

Through the intelligent monitoring system to accurately control the make-up torque, improve the quality of casing running

Through hydraulic or mechanical drive, it can achieve automatic running in casing, reduce labor intensity

To compare with traditional running in casing, no need some traditional equipment like hydraulic casing tong, reducing the operator quantity and composite cost.

It can rotate and circulate the casing at the same time when running in casing, so it reduce friction greatly and improve the success rate of running in casing operations
