FIELD: oil-and-gas production. ^ SUBSTANCE: proposed device comprises filter incorporated with electrically driven rotary pump, jet pump arranged there above, casing arranged there aligned and provided with holes in its bottom. Filter comprises hollow casing, splined shaft, filtration element shaped to truncated cone secured to cover annular clearance between hollow casing and concentric casing. Casing side surfaces have holes arranged ahead of filtration element edges. Rotary pump output makes 70% of well output. Jet pump output makes 30% of well output. ^ EFFECT: increased MTBR, higher efficiency of reservoir fluid cleaning. ^ 3 dwg |
