Gravity and magnetism data processing method and device and storage medium

The invention discloses a gravity and magnetic data processing method, and relates to the technical field of gravity exploration in geophysical exploration. The method comprises the steps: dividing regular grids according to coordinate extreme values of control points in a gravity and magnetism research area; selecting n control points for fitting a binary quadratic polynomial according to the coordinate of any control point in the regular grid; fitting a binary quadratic polynomial according to the n control points, and calculating a direction derivative and a vertical second derivative of any control point according to the fitted binary quadratic polynomial; and completing gravity and magnetism data processing of the direction derivative and the vertical second derivative in the gravityand magnetism research area according to all control points in the gravity and magnetism research area. The invention provides a new gravity and magnetic data analysis method, the processed gravity and magnetic data is not re
