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.
CZJQZ-II 360° Rotation Hydraulic Make/Break unit is designed to safely and efficiently make-up/break-out downholetoolsandmotors. It adopts a unique 360° rotational headstock clamp design. This unit is designed for fast, accurate anddependablemake up and break out of threaded connections. The 360° rotational clamp design greatly enhances the speed andaccuracyofmake-up and break-out of tools.
CZPT-II Hydraulic make-up/break-out platform is mainly used with Make/ Break unit assisting in the pre-assembly of drilling tools, whereby special guiding and alignment of tools are required for proper locking and unlocking of threads during assembly. The precision of tool alignment is the key to fast and accurate make-up and break-out of tools either in the workshop or on the rig. CZPT-II is generally designed to support all types of Make-up/Break-out Unit for its pre-assembly tool alignment and thread guiding. CZPT-II ensures high production efficiency during make- up/break-out of tools.
Application
It is suitable for all conventional wells, inclined wells and large displacement wells at all temperatures not higher than 160℃ .
Features
The superior machine structure is to further improve the machine maintainability.
The better sealing materials are selected to improve the reliability of sealing
The core mechanism adopts the seal oil bath design to reduce the wear and tear of the moving parts and improve the life of the whole machine.
The overflow area of the release channel is increased to reduce the running resistance and greatly improve the shock effect.
The operating force of hydraulic releasing mechanism can be controlled on the ground by driller, and can be flexibly adjusted according to the downhole situation.
The optional mechanical locking module is added to meet the needs of some special users. Increase the fast recovery function of the upward and downward strokes.
The mandrel moves back to the middle position, and then the jar will do jarring again in either of the two directions.
