Infuence of the paleohydrogeological conditions on the formation of the oil and gas deposits of the Perm Prikamye

In the Paleozoic section of the Perm Prikamye on the basis of the paleogeografical, paleotectonical, lithofacies conditions nine hydrogeological cycles are distinguished. The stages of the cycles and their important in the forming of the oil and gas deposits are described. The predominance at any time the elision stages of the hydrogeological cycles, which were favor for the formation the oil and gas deposits is determined.
