GRAVIMETRIC METHOD FOR MODELING GEOLOGICAL SPACE Russian patent published in 2005 - IPC

FIELD: geophysics.

SUBSTANCE: method includes measuring gravity force on earth surface, building map of gravity anomalies, averaging anomalies of gravity at plane XY in sliding window with radius R, localization of gravitating irregularities in geological space XYZ. Averaging at plane XY is performed with series of serially increasing averaging radiuses, increasing for constant value ΔR. On basis of relation between depth of placement Z of gravitating irregularity and averaging radius R within limits of researched area in given range of depths a series of N sub-parallel layers with power ΔZ is singled out, containing inside information about fragments of gravitating irregularities. A respective series of n radiography cross-sections Zi. By consecutive analysis of sections a layer-wise research of inner structure of geological space is performed. On plane XZ a network of profiles is set, on basis of which a respective network of gravimetric sections is built by projecting information about fragments of gravitating irregularities from radiography sections Zi on plane XZ of section into points belonging to lines of intersection of planes of sections with planes of radiography sections. By interpolation in sections planes a distribution of gravitating irregularities is produced. Their substance-structural identification is performed. On basis of continuous inter-profile correlation of identified in adjacent sections same-name elements a gravimetric volumetric model of geological space is constructed.

EFFECT: higher efficiency.
