The New Rotary Steering Drilling Tool and Blind Area Borehole Trajectory Spline Curve Predicting Method
This paper put forward the overall index of the new point-to-bit type rotary steering drilling tool.It briefly researched the steering mechanism mechanics model (composite beam) and the new point-to-bit type rotary steering drilling tool structure.Based on this fact, it proposes the spline curve prediction blind area trajectory method aim at the blind area existed at the small area of the front end of the drill.The paper discussed the forecast results and probe some laws: as the well depth changes, the inclination of the well path increases, and the azimuth of the well path changes slowly; when the drill build-up rate increases, the inclination angle of the well path increases.
