The upper part of the housing has a connection thread and the lower end is made in the form of a cone. Cutting and erasing elements are soldered on the conical surface in the form of strips converging at the top. Circulation of flushing fluid is carried out through slanted holes made in the middle part of the cone and side channels of the body.
The main functions of the FRC: Removal of deposits and blockages Cleaning of inner surface of casing and tubing from wax, salt and mechanical deposits. Milling of irregularities and defects Restoration of pipeline patency in case of deformations, dents or constrictions. Borehole reaming and calibration Ensures proper wellbore size and geometry before running equipment. Preparing to run packers and valves Cleans the casing to ensure a secure fit for the equipment.
Design and principle of operation: The FRC is a cone cutter with robust cutters made of carbide material. It is attached to the drill string and lowered into the borehole, where it cuts off deposits, burrs and deformed pipe sections under the action of axial load and rotation.
Advantages of using FRC: Increases well penetration Extends casing life Minimizes the risk of accidents when running equipment Improves cementing and sealing quality
The Ryber Cone Cutter is widely used in well workover and well development, as well as in preparation for new wellbores.
