Hydrothermally altered rocks – indicators of hydrocarbon unloading zones of the Krasnoleninsky arch (Western Siberia)

Our own research data as well numerous publications of recent years on modern problems oil potential in the West Siberian and gas province were used this study. Based Palyanovskaya, Talinskaya adjacent areas Krasnoleninsky arch, issues deposits structure confinement to certain regional levels section, unconventional reservoirs formation zones tectonic deformations hydrothermal-metasomatic changes pre-Jurassic basement rocks (Paleozoic granites), highly permeable “supercollector” (the lower horizons Jurassiccomplex – Sherkalinskaya formation) an almost impermeable reservoir with difficult recover huge hydrocarbon reserves (its upper Bazhenov are discussed. The distribution Jurassic part section was shown comply fluid migration model participation deep fluid. New types have been identified granites unloading sedimentary cover.
