The role of vertical migration of high-temperature fluids in the genesis of formation waters in oil-gas fields in the north of the Western Siberian basin

Abstract

All northern areas of Western Siberia exhibit a discontinuity in the normal vertical hydrochemical zoning and formation of an inversion hydrochemcial profile characterized by total mineralization of formation waters that decrease with depth and by the discovery of waters with mineralization levels of 1–7 g/L and less, as well as a simultaneous “inconsistent” change in the chemical composition of formation waters with Cl-Na-Ca to HCO3-Cl-Na deeper than 2–3 km and simultaneous “irregular’ change in the chemical composition of formation waters with Cl-Na-Ca to HCO3-Cl-Na. Based on the use of the B/Br ratio and a Na-K geothermometer, a conclusion is made that the formation of slightly (<5 g/L) mineralized hydrocarbonate-sodium waters is caused by seepage of a considerable amount of deep high-temperature (>150°C) fluids saturated with CO2 into water-bearing rocks. This indicates the formation of deposits of hydrocarbons that are found in the regions of inversion waters as result of the upward vertical, but not lateral formation migration of a water-oil mixture.
