MATHEMATICAL MODELING AND HIGH-SPEED IMAGING ANALYSIS OF ROCK FRAGMENTATION DYNAMICS DURING DRILLING OPERATIONS

Abstract

Rock fragmentation during drilling operations is a complex process influenced by various parameters, including rock properties, drill bit geometry, and operational conditions. Understanding the dynamics of rock destruction is critical for optimizing drilling efficiency and minimizing energy consumption. This study investigates the influence of rock destruction parameters on process dynamics using high-speed imaging and develops a mathematical model to describe the fragmentation process. The model integrates key variables such as rock strength, impact energy, and fracture propagation velocity. High-speed imaging is used to validate the model, providing insights into the real-time behavior of rock fragmentation. The results demonstrate the potential for improving drilling performance through optimized parameter selection.
