The energy of fluid in oil reservoir determines the direction of fluid flow. In order to study the energy distribution of fluid in fractured-vuggy reservoirs, a theoretical model of fluid potential is established, and the 3D fluid potential characterization method is determined. The mechanism models of four typical fractured-vuggy structures, single hole with bottom water, single hole with side water, double hole with bottom water and double hole with side water, are use to study the change rules of flow potential, and five main control factors affecting the flow potential adjustment effect are determined, finally, the research on potential tapping of residual oil was carried out in combination with flow potential analysis. The results show that the adjustment of flow potential for the model of single hole with bottom water make the production wells work best. The model’s water multiple is the decisive factor, and the flow potential regulation effect is better when the water multiple is less than 10 times. The greater the discharge, the better the effect of water control for production wells. The proposed fluid potential solving model of fractured and cavern reservoir can truly reflect the changing rules of fluid energy distribution in the actual formation.
