Fractured reservoirs are a key area of geophysical exploration in China's petroleum basins, and the complex fractured oil and gas reservoirs, such as carbonate rocks, unconventional tight sandstones, and shales, are also important aspects of energy security in China. New challenges arise in geophysical exploration due to difficulties in complex microstructures and fluid-filled rock physics characterization, cluttered seismic-wave field response characteristics, and problems of seismic reservoir prediction and fluid identification in complex fractured reservoirs. The rock physics response mechanism of seismic response and accurate seismic prediction method of complex fractured reservoirs are two major scientific problems. To solve these problems, the rock physics characterization theory and simulation evaluation methods for the microstructures of complex reservoirs are constructed by integrating the geological and geophysical characteristics of reservoirs with the experimental observations of seismic rock physics. In this way, a rock physical equivalent model constraint for seismic reservoir prediction is also formed. Then the characteristics of seismic wave propagation and geophysical response in complex fractured reservoirs are clarified, and the rock physics mechanism of seismic response characteristics is also revealed. Finally, the methodologies of joint probability seismic inversion for fractured reservoirs in complex frequency domain are developed in an innovative way, and the system of rock physics characterization and seismic prediction for microstructures of complex fractured reservoirs is formed as well. All these lay a theoretical and methodological foundation for efficient exploration and development of complex fractured reservoirs in the field of geophysics.
