Performances of Different Abrasive Materials During Swirling Impeller Abrasive Water Jet Drilling of Granite
Abstract Swirling impeller abrasive water jet (SAWJ) is a viable alternative for larger-diameter drilling of mining and oil and gas extraction. Abrasive material plays an important role in eco-efficient drilling of SAWJ. Here, we investigate performances of six types of abrasive materials during SAWJ drilling of hard granite. Rock breaking performances and abrasive particles characteristics before and after impact were studied. Besides, reusability, efficiency and economy of different abrasive materials were discussed. The results indicated that SAWJ would create a large-diameter (63–71 mm) hole with a conical bulge on the bottom regardless of the abrasive material used in it. Abrasive particles size distribution and shape factor before and after impacting with granite had slight changes. Moreover, median diameter of the particles and shape factor were used for estimating the reusability of the abrasive particles after impacting with granite, and the results indicated that all the abrasive materials had excellent reusability. Besides, the efficiency and economy analyses showed that the garnet abrasive had the best rock breaking performance. Therefore, we recommend garnet as the abrasive during swirling impeller abrasive water jet drilling of granite.
Highlights Performances of six types of abrasive materials during SAWJ drilling of granite.Particle size and shape factor are used to estimate the abrasive materials reusability.Garnet abrasive is recommended as the abrasive during SAWJ drilling of granite.
