摘要

FIELD: oil and gas industry.;SUBSTANCE: filter for drill column with hydraulic downhole motor, which includes hollow housing with threads on its edges and filtering module for drilling fluid, which is installed in hollow housing, tubular casing installed in hollow housing and forming together with filtering tube, inlet and outlet sleeves a receiving cavity for mechanical impurities. Module contains filtering tube with slot channels, which is attached by inlet edge to fairing, inlet and outlet sleeves provided with annular grooves and elastomer rings installed in annular grooves and designed for sealing of hollow housing. Inlet sleeve is provided with centring band directed towards tubular casing. Centring band of inlet sleeve is telescopically connected to inner inlet part of tubular casing. Annular groove is made on centring band of inlet sleeve, and inlet sealing element is installed in annular groove of inlet sleeve. At that, outlet sleeve is provided with centring band directed towards tubular casing. Centring band of outlet sleeve is telescopically connected to inner outlet part of tubular casing. Annular groove is provided on centring band of outlet sleeve, and outlet sealing element is installed in annular groove of outlet sleeve. At that, filtering tube is connected by means of thread to outlet sleeve; extension hook is fixed on front end of fairing, and external surfaces of inlet and outlet sleeves, elastomer rings and outer surface of tubular casing contact with one inner surface of hollow housing.;EFFECT: improving reliability and increasing service life of filter, improving inclined and horizontal well making accuracy.;3 cl, 6 dwg
