FIELD: oil and gas industry. ^ SUBSTANCE: invention refers to oil and gas industry and is designed for well extraction of liquid and gaseous minerals. Method of arranging a well filter includes installation of filter sections thus forming filtering jacket with end rings and following curve and making cylinder surface with the axis parallel to lengthwise rods. The filtering jacket is preliminary made flat out of a sheet material of a required size by means of cutting off triangular lengthwise grooves of uniform depth and with uniform blanks on one side, and after that a layer of material is taken off from another side of the filtering jacket along the whole area till lengthwise slits of required width are obtained. At that, in the region of slits not-cut off material creates lengthwise rods, while in the region of blanks fixing strips perpendicular to rods are formed. ^ EFFECT: facilitating guaranteed gap between lengthwise rods which increases efficiency of well filter operation. ^ 3 cl, 4 dwg |
