FIELD: oil production. SUBSTANCE: process specifically refers to methods of development of flooded inhomogeneous oil pool by water flooding from fractured-porous terrigenous and carbonate deposits, non-uniform by geological feature. Technical result of invention lies in establishment of high- efficiency, ecologically clean processes of development of flooded oil pool making it feasible to employ in active development poorly drained, low penetrable zones of pool thanks to overlap of fractures and highly penetrable zones of pool to facilitate increase of recovery of reservoir oil from pool. Process of development of flooded inhomogeneous oil pool includes successive pumping into pool through injection well of insulating agent and water fringe. Water slurry of wood dust-waste of process of veneer polishing is used as insulating agent. Water slurry of wood dust is pumped in portions, each portion of insulating agent is forced by water fringe. Ratio of volumes of insulating agent and water fringe is 1250 (dry):(8-12). According to another variant process of development of flooded inhomogeneous oil pool includes alternating pumping of water suspension of dispersive particles and clay suspension through injection well, recovery of product from production well. Wood dust-waste of process of veneer polishing is used in the capacity of dispersive particles. EFFECT: establishment of high-efficiency, ecologically clean process of development of flooded inhomogeneous oil pool. 2 cl, 1 tbl
