Abstract
This paper presents a comparative analysis of percussion-hydraulic systems aimed at optimizing the multilateral drilling process. The research focuses on evaluating the effectiveness of hydraulic pulse interaction systems in horizontal and directional well drilling, addressing the inherent limitations of traditional drilling techniques where the absence of sufficient static load reduces penetration rates. The study investigates the potential of hydraulic percussion tools to improve drilling speed, enhance borehole stability, and mitigate operational issues typically encountered in low-permeability and vertically fractured reservoirs. Key design parameters of hydraulic pulse systems, including curvature radius, axial loads, and wellbore trajectory profiles, are examined to ensure precise directional control and efficient rock destruction. Advanced mathematical models are employed to optimize parameters such as pulse frequency, impact energy, and crown rotation speed. The integration of rotary-impact techniques alongside traditional methods is explored to address challenges in drilling complex geologic formations. Furthermore, the paper proposes novel improvements to existing hydraulic systems, including enhanced spring configurations that ensure tool operation even in cases of partial spring failure. Comparative analyses with technologies such as Baker Hughes' AutoTrak and Sperry-Sun's GeoPilot illustrate the advantages and limitations of percussion-hydraulic systems in practical applications. The research concludes that the adoption of these systems significantly improves drilling efficiency, reduces costs, and enables effective multilateral well construction under challenging conditions. This study's outcomes are expected to contribute to the further development of drilling technologies in Kazakhstan and other oil-producing regions, offering promising prospects for commercialization and practical implementation.
