Intelligent optimization method of screw drill assembly based on borehole trajectory prediction

Abstract

This study constructs an intelligent wellbore trajectory prediction and BHA optimization process, which ensures efficient optimization of the BHA on the premise of high wellbore trajectory prediction accuracy, the MAE of deviation and azimuth angles of the borehole trajectory model was 0.35? and 0.55?. The optimized BHA can effectively improve the deflection effect. It also has obvious advantages in calculation efficiency and can provide effective guidance and theoretical support for on-site BHA optimization.
