RESERVOIR PHYSICAL PROPERTY PARAMETER PREDICTION METHOD AND APPARATUS

WIPO Patent Application WO/2024/087827

A1

A reservoir physical property parameter prediction method, relating to the technical field of petroleum exploration and development. The method comprises: acquiring labeled logging data, unlabeled seismic data, and seismic data to be predicted of a reservoir, wherein the seismic data to be predicted comprises elastic parameters of the reservoir; on the basis of the labeled logging data and the unlabeled seismic data of the reservoir, using an Adaboost algorithm and a greedy strategy to perform training to obtain a lithofacies prediction model, wherein the data volume of the labeled logging data for training is less than that of the unlabeled seismic data; using the seismic data to be predicted as an input of the lithofacies prediction model to obtain a lithofacies classification result of the reservoir; and on the basis of the elastic parameters corresponding to each type of lithofacies of the reservoir, obtaining physical property parameters of the reservoir. The method has the advantages of high prediction precision of reservoir physical property parameters and strong practicability. Further provided are a reservoir physical property parameter prediction apparatus, an electronic device, and a machine-readable storage medium.
