SAND CONTROL FILTER ASSEMBLY WITH MULTILAYER WOVEN WIRE FILTER MESH AND METHOD FOR MANUFACTURE THEREOF

摘要

A sand control filter assembly and method for its manufacture. Multiple filter layers of a woven wire mesh are wrapped directly onto the outer circumference of a perforated base pipe. A perforated shroud is slid over the outermost filter layer, and the assembly is run through a die to swage the shroud tightly over the multiple filter layers, thereby holding the filter layers in place and sealing their ends. In an embodiment, the woven filter mesh may be a volumetric mesh having irregular ridges and valleys to further enhance drainage.
