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.
GX-X Type Non-rotating Casing Scraper is one of the indispensable auxiliary tools for well completion, testing and downhole operation. The main purpose of the scraper is to remove cement, sand, residual bullets, scratches, paraffin, burrs and other attachments from the inner wall of the downhole casing, and protect the inner wall of the casing, so as to facilitate the normal operation of all drilling tools. Type B non rotating scraper 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.
