FIELD: oil and gas industry.
SUBSTANCE: invention relates to the oil industry and can be used in installations of electric centrifugal pumps (ECPI) for downhole oil production in conditions complicated by a high content of abrasive particles in reservoir production, as an input device for cleaning formation fluid. Device comprises a housing with upper inlets and a coaxial assembly of screws and slotted filter elements arranged in an alternating order located coaxially in the housing. Below the assembly there is a solid particle grinder with a drive shaft mounted in a spacer pipe on the bearing supports rotatably. Under the grinder of solid particles there are outlet openings communicating with the space inside the casing of the well.
EFFECT: increased time of continuous operation of the input device in the composition of the ECPI unit and, as a result, increased the operating time of the ECPI unit, decreases the intensity of the process of clogging of the well with solid particles carried out of the formation.
