METHOD OF MAPPING MAGNETIC ANOMALIES-INDICATORS OF HYDROCARBON DEPOSITS

摘要

FIELD: data processing.;SUBSTANCE: invention relates to geophysics and can be used for mapping magnetic anomalies-indicators of hydrocarbon deposits. Magnetic anomalies are detected from high-accuracy aeromagnetic survey data. Aerogravimetric survey is carried out. Gravitational anomalies are recalculated into pseudomagnetic anomalies. Pseudomagnetic anomalies are subtracted from magnetic anomalies. Magnetic anomalies-indicators of hydrocarbon deposits are mapped from obtained difference.;EFFECT: high accuracy of mapping.;1 cl
