Abstract

The available data show that the hydrogeology of the Nyurol'ka basin is characterized by widespread connate waters, in places diluted by ancient percolating waters. This basin has vertical hydrodynamic and hydrogeochemical zoning. Combined with elision, this favors oil and gas formation. We have established that the Lower-Middle Jurassic sediments are fed by their own saline waters as well as by the waters of Paleozoic and Upper Jurassic complexes at the sites where permeable sediments exist. This explains mixing of different genetic types of waters in the sediments. We have first revealed the existence of vertical water cross-flows between aquiferous complexes, which generally does not disturb their hydrodynamic isolation.
