Abstract

The invention provides a method for calculating two-dimensional body gravity anomaly. According to the method, complex two-dimensional body model representation and rectangular model gravity anomaly calculation steps are implemented, wherein the rectangular model gravity anomaly calculation comprises the steps of weighting coefficient calculation, one-dimensional discrete convolution calculation and gravity anomaly synthesis. According to the method, unity of gravity anomaly in efficiency and precision is implemented.

Description

technical field [0001] The invention relates to a calculation method for second-degree gravity anomalies, in particular to a fast and high-precision calculation method for second-degree gravity anomalies with arbitrary cross-sectional shapes and arbitrary density distributions. Background technique [0002] Gravity prospecting is based on the earth's gravity field and density difference as the physical basis. It is a geophysical prospecting method for studying the earth's structure and searching for mineral resources. Multiple conditional restrictions. The forward calculation of gravity anomaly refers to the calculation of gravity anomaly based on the density distribution, and the inversion refers to the calculation of the density distribution based on the observed gravity value. Forward modeling is the basis of inversion, the efficiency of forward modeling directly affects the efficiency of inversion calculation, and the accuracy of forward modeling directly affects the qu...
