DENSITY DETERMINATION METHOD AND APPARATUS, AND ELECTRONIC DEVICE

WIPO Patent Application WO/2023/280122

A1

A density determination method and apparatus, and an electronic device, which are applied to the technical field of geophysical exploration. The density determination method comprises: acquiring Bouguer gravity anomalies at a plurality of measurement points set for a target body to be measured; for each measurement point, determining the Bouguer gravity anomaly of said target body at the measurement point on the basis of the Bouguer gravity anomalies at the plurality of measurement points and taking same as a first anomaly at the measurement point, and on the basis of the Bouguer gravity anomalies at the plurality of measurement points, determining a Bouguer gravity anomaly, at the measurement point, of a reference body corresponding to said target body, and taking same as a second anomaly at the measurement point; for each measurement point, calculating the difference between the first anomaly and the second anomaly at the measurement point, and taking same as a local gravity anomaly; and performing density inversion on said target body on the basis of the local gravity anomaly of said target body at each measurement point, so as to obtain a density distribution of said target body on a cross section. By means of the method, the density of a target body can be acquired more accurately.
