In recent years, the proportion of glutenite oil and gas reservoirs in newly proven reserves has increased year by year, and the development of glutenite oil and gas reservoirs has gradually received attention. Glutenite has the characteristics of low permeability and poor conductivity. Large-scale hydraulic fracturing is required to form a fracture network when developing these reservoirs. However, because gravel hinders the formation of complex fracture networks, the fracturing effect of glutenite is not ideal. Therefore, in view of the structural characteristics of glutenite and based on the theory of fracture mechanics, hydraulic fractures in glutenite formations are taken as the research object to explore the influence of gravel on the propagation of hydraulic fractures when the glutenite formation is fractured. The research results show that after the interaction between hydraulic cracks and gravel, the expansion of hydraulic cracks is mainly around the gravel, and in a few cases it will pass through the gravel. The shape of the gravel has a significant influence on the behavior of hydraulic cracks expanding around the gravel. As the expansion direction of the hydraulic crack changes during the course of expanding around the gravel, it is more and more difficult for the hydraulic crack to expand around the gravel. The smoother the shape of the gravel is, the easier it is to expand the hydraulic fracture around the gravel. This study further reveals the law of interaction between hydraulic fractures and gravel, which has certain reference significance for the development of glutenite oil and gas reservoirs.
