Beschreibung
Zusammenfassung:	oil industry. SUBSTANCE: given process can be employed to recover residual or difficult-to-extract oil at late stage of exploitation of oil fields. Process consists in passing of direct current of 150-450 V, current density of 0.1-10.0 A/sq.cm through pool multicomponent mixture in well. Casing of well is used in the capacity of cathode. Electrode placed in perforation zone of well is employed as anode. Thus flow of ion-plasma processes in pool mixtures is provided. Continuous pumping of mineralized water from well-head is conducted. High-temperature front facilitates softening of oil asphalt and products of electrolyte- plasma processes dissolve mineral blobs of various compounds, reduce surface tension making it possible to wash away adhered oil and to penetrate smallest pores putting untouched sections of pool into service. EFFECT: enhanced oil recovery. 1 cl
