String Magnetic

YTQC type string magnetic is one of the auxiliary tools to ensure normal drilling operation and bottom hole cleaning after downhole accident treatment. The main feature of this product is that it works together with the junk mill in the fishing operation, which is different from the previous practice of lifting the drill after milling, and then connecting the drill string with the strong magnetic fishing device to go down the well for bottom hole cleaning, saving a trip down the well, which saves both drilling costs and fishing time.

Tianhe Downhole motor design d on the most advanced international design technology. We have a Closely cooperating with domestic, surgical research institutes, universities and oilfield drilling companies, and through careful research and development of R & D center in Canada, the design of technical parameters and structure can meet the most demanding oil drilling needs. Tianhe downhole motor is designed for durability and longer service life for different use conditions, with the most stringent specific tolerances for design and manufacturing standards.

The common drill pipe is a rod that connects the drill bit, delivers the drilling fluid and transmits the power in the drilling tool. Our common drill pipe conforms to SY/T5561 and API Spec5DP standards. In order to reduce the wear of the casing and drill pipe, we can weld the wear belt at the end of the drill pipe female buckle joint. Our company has obtained the production and use license of ARNCO 100XT, ARNCO 150XT, ARNCO 300XT and ARNCO 350XT authorized by the American Anke company.

The agitator can improve the effectiveness of bit weight transfer and reduce the friction between drilling tool and borehole through the longitudinal vibration produced by the hydraulic action of drilling fluid, especially in the process of directional drilling to improve the bit weight transfer and reduce torsional vibration. It is a downhole tool used to solve downhole depressurization and improve weight on bit transfer. Smooth weight on bit transfer improves the ability to adjust the bit toolface to reach further target zones. It does not require too much work to adjust the tool face during drilling, keeping the tool face stable and increasing ROP. Particularly suited for horizontal, extended-reach Wells, it can be used in conjunction with MWD, screw, and any bit.

 
 

Working principle

Main working principle: during milling and fishing operations, the debris at the bottom of the well is under the action of slurry circulation, it will be adsorbed on the strong magnetic field body of the drill string, and these debris will return to the ground from the bottom together with the strong magnetic field of the drill string, so that the bottom hole can be cleaned at any time during milling operation.
