  • Carbonate reservoir is rich in oil and gas reserves; however, the complex fracture and cave structure of the carbonate reservoir, forming through a long-term geological structural movement, lead to some difficulties in oil and gas exploitation. For this engineering problem, we use an in-house numerical model-KarstEvolSys to study the effects of fracture density and the magnitude of rainfall on the dissolution of carbonate rocks. Numerical simulations have been performed by controlling the number of fractures embedded in the matrix and the velocity supply to the fracture system. Our results show that the more fractures embedded in the matrix, the less water flow captured by each fracture, which leads to a relatively slow increase of the fracture aperture when the fracture density increases. When the magnitude of rainfall remains constant, the dissolution rate of rock mass becomes slow accordingly. If the same karst system is supplied by different amounts of rainfall, the water would dilute Ca2+ concentration in the system,speeding up the water-rock reaction. Therefore, the increasing rainfall would lead to a higher dissolution rate of the rock mass.
