Abstract There are a large number of discontinuous interfaces such as natural fractures，faults and bedding planes in deep reservoirs. These interfaces dominate the generation of the fracture network and efficiency of the stimulation treatment. This paper presents a brief review on the study of hydraulic fracturing in reservoirs with interfaces in three aspects：experiments，theory and numerical simulation. Firstly，this paper investigates the current state of laboratory hydraulic fracturing experiments including loading mode，sample preparation and fracture monitoring. Secondly，based on the results of hydraulic fracturing experiments，the theory of the interaction between hydraulic fracture and single interface is analyzed. In addition，the key factors affecting the generation of the fracture network are concluded. Then，the difficulties of numerical simulation of the interaction between hydraulic fractures and the interface are presented. The treatment of the fracture intersection，and the numerical research progress of the interaction between hydraulic fractures and interfaces and the generation of fracture network are reviewed. Finally，a few issues and trends of hydraulic fracturing research in reservoirs with interfaces are proposed.

Key words： rock mechanics hydraulic fracturing natural fractures interface interaction fracture network
