Abstract

A multidiscipline seismic and gravimagnetic survey, as well as paleomagnetic and lithologic-stratigraphic analysis of pre-Jurassic formations were conducted in North- Ostaninsk oil field within south-east Western Siberian petroleum province. A multidirectional tectonic deformation network merging into the destruction zones of Paleozoic basement was identified. The material composition and age of pre-Jurassic formations within each tectonic block were determined. Fundamentally new geological structure model of the Paleozoic suite was proposed : North-Ostaninsk erosion-tectonic protrusion - a reversed and structurally-complex fracture - deformed tectonic syncline fold where the oil reservoir is confined to the dipping limb. Reversed morphostructures in the erosion-tectonic protrusions could be a prospecting indicator in evaluating the hydrocarbon potential of Paleozoic sediments.
