AI Technical Summary
Existing rotary steerable drilling technology suffers from problems such as insufficient directional drilling capacity, short system life, inadequate release of drilling parameters, and poor wellbore smoothness, which are particularly evident in complex formations.
The push-direction rotary steerable drilling system adopts a bottom flexible sub and bottom centralizer near the drill bit, combined with automatic tool application of push force to achieve drill bit direction deviation and trajectory control, avoiding the use of easily broken mandrels and enhancing the system's flexibility and stability.
It improves trajectory control capabilities, extends system life, enhances wellbore smoothness and drilling speed, adapts to drilling in complex formations, and improves drilling efficiency.
