description The utility model relates to a novel filter for producing oil. A metallic fibre tube 2 is arranged between a casing tube 1 and a central tube 3, the metallic fibre tube can be composed of a plurality of manufactured short metallic fibre tubes 4 which are connected top and bottom vertically, and a plurality of eyelets 4 are arranged on the tube walls of the casing tube and the central tube. The metal fibre tube has good permeability for liquids and sand preventing capability, the metal fibre tube also has good performances of high temperature resistance and bending resistance, and the clogging of sand granules can be conveniently eliminated without disassembling the metal fibre tube, so that the utility model can be used repeatedly. The utility model has the advantages of improving the efficiency of oil production, improving the quality of crude oil and reducing the production cost.
