Abstract

Large amounts of oil and gas resources are stored in carbonate rocks, and fracturing is an important technology to exploit carbonate reservoirs, The communication between artificial fractures and natural fractures is very important for the fracturing effect of carbonate reservoirs, The effect evaluation after fracturing lacks quantitative description. Therefore, it is necessary to study the fracturing effect evaluation of carbonate reservoirs. This paper analyzes the pressure curve obtained in true triaxial fracturing experiment. The communication with natural fracture and vugs in the process of fracture propagation is explored. Finally, the pressure curve characteristics of artificial fracture communicating with natural fracture cavity under different modes are obtained, and the communication between artificial fracture and natural fracture is identified.
