Oil and natural gas are closely related to people's daily needs and the production of various industries. In recent years, oil and gas price volatility has brought renewed attention to the oil and gas industry. This paper sets out to study how external shocks and internal risks affect the stability of oil and gas supply networks and thus the global energy supply. The structure and fragility of the oil and gas supply network and the impact of the fragility of the supply network on the Russian Federation's oil and gas supply are described through a literature review. Finally, it is found that the composition and scale of the supply network, the harsh mining environment, the unstable financial market, the technical difficulties, the safety of practitioners, and other factors all have a significant negative impact on the global energy supply.
