DEVICE FOR SEISMIC SURVEY 2D OR 3D, ELECTRICAL EXPLORATION AND GIS TO INCREASE RELIABILITY OF MAPPING THE ROOF OF SALT AND FOR PREDICTION OF OIL AND GAS CONTENT SUBSALT DEPOSITS IN AREAS WITH DEVELOPED SALT-DOME TECTONICS

摘要

FIELD: geology.;SUBSTANCE: invention relates to prospecting and can be used for regional and exploratory geological works at direct search and exploration of oil and gas deposits. Purpose of invention is the use of the device for exploration of oil and gas in complex built areas with developed hydrochloric dome tectonics. In particular, complex of geophysical exploration provides execution for complex integrated field operations in a single network of profiles for implementation of complex measurements of seismic and electromagnetic fields using differential-normalized electrical exploration method (DNME), combined analysis of the obtained data in a single information environment. Survey using this device is used to increase reliability of mapping salt structures roof and studying their internal structure, which significantly affects the reliability of structural calculations of subsalt deposits and forecast of their oil and gas content.;EFFECT: technical result is high accuracy and reliability of structural calculations of subsalt deposits and prognosis of their oil and gas content.;9 cl, 8 dwg
