PROCESS OF EXPLOITATION OF INHOMOGENEOUS OIL POOL Russian patent published in 2001 - IPC

FIELD: oil production. SUBSTANCE: invention is intended to increase oil output of inhomogeneous pools at any stage of flooding. Process of exploitation of inhomogeneous oil pool includes pumping of aqueous solution of immobilized microbe cells through injection well. Following composition, per cent by mass: microbe biomass of biochemical production of protein-vitamin concentrates 0.5-10.0; adsorbent-chalk 0.15-3.0; water being the balance, is utilized in the capacity of above- mentioned aqueous solution. EFFECT: increased oil output thanks to improved insulation of jointing washed zones of pool. 2 tbl
