FIELD: oil and gas industry.
SUBSTANCE: invention relates to oil industry and can be used for cleaning of well fluid from floating garbage caught in well at various process operations, or sludge. Proposed device comprises tubular perforated body with connection threads at its ends, collector arranged thereon and provided with funnel with conditional outer diameter smaller than that of the well. Upper connecting thread of the housing is equipped with an element for attachment of the device for delivery of the device to the well. Collector is equipped uniformly along perimeter and height with drain holes with diameter not passing large refuse and sludge. Element for fastening of delivery devices is located at 10–50 cm above center of gravity of collector. Housing below collector, but above lower connection thread, is equipped with fine filter, and inside collector housing is fixed coaxially rigid centering device.
EFFECT: simplified design, possibility of passage of complex boreholes.
