The Drill Bit Steering System comprises six components: communication module, power module, control module, electrical module, actuator module, and drill bit module. The power module utilizes a straight screw motor, which eliminates the lateral forces caused by the geometric bend of conventional screw motors during composite drilling. This reduces the risk of cutting tooth failure, increases the drill bit's penetration rate, shortens the drilling cycle, and lowers drilling costs. Straight screw drilling also eliminates spiral-shaped boreholes, ensuring smooth subsequent operations. The control and actuator modules operate during directional drilling, with the push block pressing against the borehole wall to apply lateral force to the drill bit, enabling directional drilling.

Key Features

Straight Screw Drilling: Eliminates lateral forces from bent screw motors during composite drilling, reducing drill bit damage, increasing penetration rate, and shortening drilling cycles.

Optimized Borehole: Prevents spiral-shaped boreholes, ensuring smooth subsequent operations.

Directional Drilling Capability: The control module receives surface commands to direct the actuator module, applying lateral force to the drill bit for directional drilling.

Simple Operation: Surface control instructions are transmitted via high/low flow rate changes.

Hydraulic Mode: Push block operates via hydraulic pressure, ensuring stability and reliability.

Variable Diameter Stabilizer: The upper part of the tool can be connected to a variable diameter stabilizer to meet diverse trajectory control requirements.
