Abstract

A downhole tool for preventing pump blockage includes an outer conduit defining an outer flow path, an inner conduit located within the outer conduit defining an inner flow path and a space between the inner conduit and the outer conduit. The inner conduit includes one or more angled passageways to allow one-way debris flow. A pressure regulated valve is coupled to the upper end of the outer conduit and configured to open to expand an adjustable width angled passageway defined by the pressure regulated valve. An upper end of the inner conduit is configured to allow fluid bypass of the angled passageways of the inner conduit when the angled passageways are blocked with debris.
