Abstract: During the second round of trail mining of natural gas hydrates in China, multi-stage perforation injection via horizontal wells was used to improve the extraction efficiency, demonstrating the potential application of hydraulic fracturing technology. However, the effectiveness of perforation in hydrate-bearing sediments remains inadequately understood and requires further investigation. To address this, experimental simulations of impact-induced fracturing in such sediments were carried out through two types of experiments: perforation tests and drop-weight impact tests. These experiments examined the relationship between impact energy and fracture area. The results indicate that higher loading rates promote more effective fracture initiation. Additionally, greater total impact energy applied over a shorter duration was found to be more conducvie to fracturing, resulting a larger fracture area. Nevertheless, the efficiency of the energy transformed into fracture in the current experiments was relatively low, highlighting an area in need of further study.
