METHOD FOR CREATING TECHNOGENIC OIL DEPOSITS IN LITHOSPHERE

摘要

FIELD: biochemistry.;SUBSTANCE: invention relates to the production of secondary fuels and can be used for the disposal of liquid biological waste with the simultaneous production of biofuels, similar in composition to crude natural oil. This method for creating a technogenic oil field in the lithosphere includes drilling injection and pumping wells to a depth of the lithosphere with a pressure of 11–15 MPa, a temperature of 60–124 °C and reservoir porosity of 8–9 %, delivery of untreated municipal wastewater into injection wells with an organic matter content of at least 100–300 mg/l and a volume of at least 20 thousand m³/day, carrying out hydraulic fracturing, holding effluents until the formation of technogenic oil and its subsequent extraction on the surface, at the same time, drilling of wells is carried out at a distance calculated on the basis of the rate of migration of organic waters and the period of synthesis of technogenic oil.;EFFECT: acceleration of the production and improvement of the quality of the volumes of oil obtained from untreated urban effluent and an increase in the volumes of extracted oil with simultaneous disposal of human waste are ensured.;1 cl
