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.

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.
YTQC Type Drill String Fishing Magnet is one of the auxiliary tools to ensure the normal drilling operation and bottom hole cleaning in the process of downhole accident treatment. The main feature of this product is that it works together with the grinding shoes in the fishing operation, which is different from the previous method of lifting the drill after milling, and then connecting the drill string with the strong magnetic fishing tool to go down the well for cleaning bottom hole , saving a trip down the well operation, which not only saves the drilling cost, but also saves the fishing operation time.
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.
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.
