The internal self rotating components of the tool convert fluid energy into traction torque; Conical eccentric crown, rotating over steps and repairing wellbore walls; The auxiliary roller can reduce the forward resistance of the shoe guide。

Main features:

1. The shoe head is designed with self rotation, which can automatically change direction and guide the casing to smoothly run in if local steps on the wellbore are obstructed during the process of running the casing;

2. The toe of the shoe can rotate and pump to use drilling fluid to drive the shoe to rotate freely;

3. Due to the use of fluid driven shoe free rotation design, in the process of running casing, if encountering mud cake accumulation, sediment deposition on the wellbore wall, local shrinkage and other obstacles, the pump can be opened to circulate drilling fluid, so that the shoe head can rotate and scrape off the mud cake, and sediment can guide the casing to run smoothly;

4. Suitable for use in vertical wells, directional wells, highly deviated wells, and horizontal wells;

5. A large flow channel area can meet the needs of cementing and cement construction;

6. The material of the guide shoe is 40CrMnMo, which has good mechanical properties and meets the impact resistance requirements during the casing process;

7. The middle of the guide shoe is embedded with a roller, which can reduce the downward resistance of the sleeve.
