The purpose of a downhole torque reducer is to reduce excessive torque generated during drilling in short-radius horizontal sections and high-angle well sections. It is mainly connected in short-radius horizontal sections and high-angle well sections. It is recommended to connect one torque reducer every 60 feet. After its use, the torque can be reduced by 25-35%. Its spiral inner sleeve, straight outer sleeve and core shaft are in a relatively non-rotating state.

The main purpose of the cleaning pup joint is to remove cement, sand, residual bullets from perforating, scratches, paraffin, burrs, and other attachments from the inner wall of the downhole casing, to keep the inner wall of the casing clean, so that various downhole tools can be run. It is commonly used in horizontal wells and large displacement well sections. Its double helix structure can effectively remove internal wall debris, and at the same time, wear-resistant materials can effectively extend the drill pipe's service life.

Floating valve connectors are essential tools in oil drilling. A floating valve connector is a drill string connector, mainly including drill bit floating valve connectors and drill string floating valve connectors. Its main functions are: to prevent drilling cuttings and sand from being carried into the drill bit water eyes when connecting single strings; and to prevent well blowout accidents in the drill string when a well blowout or surge occurs. The floating valve assembly cover automatically closes the water eyes to prevent well blowout accidents in the drill string.
