FIELD: mining industry.
SUBSTANCE: method includes marking raised and depressed portions in ceiling of salt deposit by drilling reconnaissance wells. Then regional tectonic structures are marked and tectonic zones positioned between them, and also between regional tectonic structure and limit, separating platform from salt-bearing depression. Sub-layer model of deposit is built, separating sub-salt, salt and super-salt rock complexes. Value of displacement of tectonic zones during transfer from super-salt complex t salt complex is determined, and also level of positioning for each bed, after that horizontal shifts are detected, which complicate tectonic zoning. Possible geological complications are predicted during mining operations.
EFFECT: higher personnel safety, higher efficiency.
