FIELD: oil and gas industry.
SUBSTANCE: invention relates to the equipment for production wells and can also be used in water production wells. The device includes an array of the same type of filter elements made of waterproof material, packaged and manufactured according to a digital 3D model using 3D printing. The filter elements are formed by a plurality of vertical screens that block the direct radial flow of liquid and are connected into a spatial frame by conical surfaces of truncated cones with large bases directed towards the bottom. The proportion of open pore space in the working volume of the filter is at least 30%.
EFFECT: porosity increases, material consumption decreases, and the filter service life increases.
