Non-Rotating Casing Scraper

The non-rotating casing scraper is one of the indispensable auxiliary tools for well completion, testing and downhole operations. Its main purpose is to remove cement, sand, scratches, paraffin, burrs and other attachments on the inner wall of the downhole casing, protect the cleanness of the inner wall of the casing, and facilitate the normal operation of all drilling tools.

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.



Each set of products is composed of four rows of cutter plates, which can realize 360 degree all-round non-dead angle scraping. The cutter plate does not rotate with the drill string, and only moves up and down relative to the inner wall of the casing, without rotating movement, so the casing will not be damaged.
