K-Roller - highly-deviated well flywheel
The tool can be RIH by slickline or E-line. The patented product specially designed to help the tool string enter into the highly-deviated well. It has been widely used by oil and service companies all over the world. It has the functions of equal aperture perforation, cable signal, magnetic tool center, rotating tubing and etc., to reduce resistance, supporting, suspending and centering. The domestic using record is entering a section with a high deviation of 86 degrees in Jidong Oilfield without assistance of external force (no drive) in 2016.
Application - Wide application: it is suitable for all well conditions and meets all task requirements of user. It can be applicable to cased hole, open hole, perforation, logging, cable, slickline and tubing.
Characteristics - RIH speed can reach a rate of 20 m/min
- Customized: customize the wheel with optimal size based on size of tool and borehole to increase the traveling distance.
- Carrying mode: it can be mounted on the surface of tool/tubing/casing, or connected up and down with the tool
Advantage - Sealed bearing: avoid the blockage by sand, mud and debris in the well and prevent from locking of wheel
- No screw: the flywheel body is free of any screw. Therefore, there is no risk of screw falling in the well.
- Silicone oil injection design: the bearing can be filled with silicone oil before going into the well to achieve the cleaning-sealing-drag reduction effect
- Biaxial rotation: the flywheel can rotate transversely and longitudinally to minimize the resistance while RIH and to move farther in horizontal section.
