摘要: Natural gas and oil is the major energy resource of the world. Carbonate formations are the most important target of future ultra-deep energy exploration and enhanced oil/gas recovery. Heterogeneity of carbonate rocks, however, remains to be the most challenging problem to cause low reserve estimate and low recovery rate. Carbonate pore structure variation due to deposition and diagenesis severely affects both elastic properties and permeability in space and time. Unlike siliciclastic rocks, diagenesis is the most significant geological control on carbonate reservoir heterogeneity. Using core and log data, geological influence on seismic velocities and permeability can be analyzed. Rock physics model based on poroelasticity further provides a vital link to characterize quantitatively the geological influence. Both porosity and pore-structure parameter can be simultaneously estimated from pre-stack seismic data. Field examples illustrate the feasibility of the method to improve reserve estimates and to predict permeability.
