Abstract

The application relates to the computer technical field, and particularly discloses a three-dimensional quality factor volume construction method, device and equipment and a storage medium. The method comprises the following steps: acquiring well acoustic wave data and ground three-dimensional seismic data; determining well-ground joint matching layered factors based on the well acoustic wave data and the ground three-dimensional seismic data; constructing a quality factor volume layered initial model based on the ground three-dimensional seismic data and the well-ground joint matching layered factors; correcting the quality factor volume layered initial model by using well acoustic wave data of different offset distances to generate a target three-dimensional quality factor volume, and determining a target three-dimensional quality factor through the target three-dimensional quality factor volume. Through the technical scheme, the accuracy of the well acoustic wave data and the expansibility of the ground three-dimensional seismic data are simultaneously utilized, the accurate establishment of the target three-dimensional quality factor volume is realized, and the determined quality factor volume has higher accuracy and reliability.
