FILTER OF SOLID PARTICLES FOR OIL, GAS AND WATER, PROCEDURE FOR ASSEMBLING SAID FILTER, PROCEDURE FOR ASSEMBLING A PIPE STRUCTURE INSIDE THE CASING OF A WELL IN ORDER TO INSTALL THE FILTER AND SAID PIPE STRUCTURE

摘要

A filter of solid particles for oil, gas and water that comprises a headpiece made of a pipe substantially resistant to the chemical and physical damage caused by the material to be filtered, with the surface of said pipe defining a filtration area comprising a plurality of perforations that allow fluid to pass through the wall of the pipe, wherein said pipe comprises nuts on the ends thereof; a plurality of filtration rings made of a plastic material assembled in a concentric shape on said filtration area of the pipe, said rings being placed in parallel on top of each other, and wherein each of the rings comprises a plurality of internal extensions providing support on and separation from the pipe, defining a space for the fluid to circulate between the inner borders of the rings and the surface of the pipe, and one of the surfaces of each ring comprises perpendicular guiding extensions that fit into corresponding fitting perforations present in the neighbouring rings, and a plurality of supports distributed along the perimeter on one side of the ring, with the height thereof providing a distance of separation determined by the particle to be trapped; and at least two supporting rings mounted on the pipe and placed on each end of the set of filtration rings, adjusting and defining at least one section, wherein each of said rings is adjusted on the pipe by fixing means.
