Ultra-deep carbonate fracture-cavity reservoirs present numerous challenges in reservoir prediction due to their complex geological structures and variable reservoir characteristics. This paper thoroughly explores the difficulties in predicting these reservoirs, including the complexity of geological structures, difficulties in data acquisition, and the complexity of multi-phase media. It proposes an integrated multi-technology solution. By comprehensively applying multidisciplinary techniques such as seismology, geology, geophysics, and numerical simulation, the aim is to provide a scientific basis and methodological support for reservoir prediction in ultra-deep carbonate fracture-cavity reservoirs, thereby improving prediction accuracy and reducing exploration risks.
