GS (I) Type Casing Brusher
GS (I) Type Casing Brusher is one of the indispensable auxiliary tools for well completion, testing and downhole operation. Its main purpose is to remove the residual attachments after the scraping operation of downhole casing inner wall scraper and protect the cleanness of casing inner wall, so as to facilitate the normal operation of all drilling tools. It is usually used with casing scraper.GS (I) Type Casing Brusher is not suitable for drilling operation.

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.
Product Introduction：
GS (I) Type Casing Brusher is one of the indispensable auxiliary tools for well completion, testing and downhole operation. Its main purpose is to remove the residual attachments after the scraping operation of downhole casing inner wall scraper and protect the cleanness of casing inner wall, so as to facilitate the normal operation of all drilling tools. It is usually used with casing scraper.GS (I) Type Casing Brusher is not suitable for drilling operation.
Product Structure：
GS (I) Type Casing Brusher (Hereinafter referred to as casing brusher) is composed of mandrel, centralizing sleeve, steel brush support, steel brush, etc. The centralizing sleeve is installed in the middle of the mandrel. The diameter of the centralizing sleeve is slightly smaller than the inner diameter of the casing. It can rotate freely on the mandrel and play the role of centralization when cleaning the inner wall of the casing. Select the center sleeve and steel brush with corresponding size according to different casing inner diameter.
Construction and Principle：
After cleaning the inner wall of the casing with the casing scraper, because the scraper is rigid, there will be a small gap between the scraper and the inner wall of the casing, and some attachments will remain after the scraping operation. At this time, the casing can be further cleaned with a Casing Brusher. The steel brush has toughness and can fully contact the inner wall of the casing to brush the inner wall of the casing; The centralizing sleeve plays the role of centering, so that the steel brush on the circumference can evenly contact with the inside of the casing, and protect the steel brush from excessive extrusion with the inside of the casing.
Care & Maintenance：
After each use, the casing brusher should be cleaned, and do not store it for a long time to prevent the steel brush from
rusting.
Visually inspect all parts. If the steel brush is found to be seriously worn, replace with a new one.
All main parts shall be inspected by flaw detection. During assembly, apply high-quality grease on each thread and
enough antirust oil on other parts to keep the casing brusher in good condition for use.
