Concave Bottom Mill is a specialized grinding and milling tool used in petroleum drilling and workover operations, mainly for under-reaming fish top trimming, casing repair, and metal debris grinding. Its unique concave design can improve milling efficiency and protect the wellbore.
Pilot Mill is an efficient grinding and milling tool used in petroleum drilling and well-servicing operations, mainly for precise processing of fish top in the wellbore. It achieves stable grinding through a central guiding structure, creating ideal conditions for subsequent fishing operations.
Flat-bottom shoe grinding is a fundamental grinding and milling tool in petroleum drilling and well repair operations. It is mainly used for reworking the fish top fallen in the well, grinding metal debris, and cleaning the wellbore. Its flat design is suitable for large-scale grinding tasks and is a conventional solution for handling downhole metal obstructions.
Casing milling shoes are efficient wellbore cleaning tools used in petroleum drilling and workover operations. They are mainly used to remove cement rings, hard deposits, or metal residues attached to the casing wall, restoring the wellbore diameter and providing a clean environment for subsequent operations.
The tapered milling shoe is an efficient milling tool used in petroleum drilling and well repair operations, mainly for handling complex fishings, casing restrictions, or irregular wellbore sections downhole. Its tapered design enables progressive grinding, creating ideal conditions for subsequent operations.
