According to the results of FMI log interpretation and the water cut trend of low permeable carbonate reservoirs, the model of the fluid distribution in the fracture-cavity pore was derived. Based on the material balance principle, assuming the original water contribution to production as constant water influx, a new calculating method for the low permeable carbonate reservoir geological reserves was presented. This method estimated the impact of origin aquifer to the geological reserves. The calculating results of example indicate that comparing to numerical simulation, this new method is high accuracy and easy to use.
