METHOD FOR DETECTION OF ANTICLINAL TRAPS OF HYDROCARBONS IN YOUNG SEDIMENTATION BASINS

摘要

FIELD: oil and gas industry.;SUBSTANCE: aeromagnetic, ground magnetic or hydromagnetic surveys of an oil-and-gas bearing area are performed. Abnormalities of a local component of a residual magnetic field are detected. Closed negative abnormalities are detected. Configuration and density of isolines of negative closed abnormalities of the local component of the residual magnetic field is assessed. Angles of inclination lines of the abnormal magnetic field are determined as per profiles passing through the closed isolines of the negative component of the local magnetic field.;EFFECT: improving search efficiency of hydrocarbon deposits.
