ABSTRACT:
A method of manufacture of a long radial-flow filter particularly suitable for use as an input filter in a subterranean fluid (oil, gas, water) well starts with a length of multi-perforate pipe, which may be an integral part of the well 's production tubing. The pipe is mounted in an engine lathe with the perforated length between the headstock and the tailstock of the lathe. With the pipe rotating, a strip of metal (steel) wool is wrapped around the pipe in repeated, overlapping helical layers each aligned at an acute angle X to the pipe axis, with adjacent layers angularly displaced by 2X. The completed filter has a tubular wire mesh around the pipe, between the pipe and the innermost layer of steel wool, and a multi-perforate sheath over the outermost layer of wool.
