The AJ type safety joint is a specialized tool used for emergency separation of downhole tubulars in petroleum drilling operations. It belongs to the high-performance products in the safety joint series and is especially suitable for deep wells, ultra-deep wells, and complex well conditions.
The H-type safety joint is a special emergency tool used in petroleum drilling operations, mainly for the safe separation and retrieval of downhole tubulars. In emergency situations such as stuck pipe or tool jamming, it can quickly release the stuck tubular, protecting the upper drilling tools and reducing accident losses.
The back-off tool is a specialized tool used in petroleum drilling operations for emergency separation of downhole tubulars. It is mainly used to safely disengage stuck drilling tools during stuck pipe incidents, preventing more severe downhole complications caused by forced drilling.
The milling tool is a specialized tool used in oil drilling and well repair operations, mainly for casing window milling, casing section milling, and wellbore restoration tasks. It precisely mills windows or removes specific casing sections on the casing to create conditions for sidetracking, perforation, and other operations.
The mechanical internal cutter is an efficient cutting tool used in petroleum drilling and well-servicing operations, specifically designed for precise cutting of casing, tubing, or drill pipe inside the wellbore. It is suitable for operations such as fishing, well abandonment, or wellbore repair.
Mechanical external cutters are specialized cutting tools used in petroleum drilling and workover operations, primarily for efficient cutting of casing, tubing, or drill pipe from the outside of the string. They are suitable for operations such as well abandonment, fishing, and wellbore repair.
The keyway expander is a specialized tool used in petroleum drilling operations to repair keyway stuck pipe issues in the wellbore. It enlarges the wellbore diameter in the keyway section through mechanical cutting or grinding methods, restoring free movement space for the drill string and preventing the worsening of stuck pipe incidents.
The lead shoe is a tool used to detect the condition of the fish top and the casing running status downhole. It is divided into two structures: with water holes and without water holes. The one with water holes is designed to facilitate flushing the fish top.
