The present disclosure provides a method, device, and computer equipment for determining the volume of carbonate fracture-cavity reservoirs, and belongs to the technical field of oil and gas reservoir development. The seismic attribute values ​​of three-dimensional seismic data and carbonate rocks can reflect the existence of fractures and caves, but the correspondence between the existence of fractures and caves is not accurate enough.

A relatively accurate correspondence can be established between the seismic attribute values ​​and the actual fracture-cavity thickness values. Based on the relatively accurate neural network model, a relatively accurate volume of the fracture-cavity reservoir in the carbonate rock area can be further obtained, which can effectively adjust the specific distribution of subsequent development wells, maximize the development of oil and natural gas, and be conducive to the good development of oil and natural gas.
