Downhole Drilling Mechanics Analysis Based on Closed-Loop Rotary Steerable Drilling System

Abstract:

Design of closed loop drilling tool in the rotary steering drilling system is a bit in recent installation guide controlled stabilizer, and placed on the upper drill collar two downhole assembly form of stabilizer. The set of parameters for the MATLAB software programming is used to solve the three moment equation and the downhole assembly mechanical properties. With continuous beam column theory, the mechanics features of the BHA are analyzed. It is analyzed focused on the relationship between the guiding force and the bit deflecting force, the relationship between the hole deviation angle and bit deflecting force, the relationship between the drill press and bit deflecting force, the relationship between the guiding force position on the well inclined plane and bit deflecting force through the tables and figures based on closed-loop rotary steerable drilling system.
