Abstract
A dual use fluid filtration tool to separate both solids and gas from a fluid. The fluid filtration tool is suspended from and connected to downhole equipment, such as a downhole submersible pump having a motor, which rotates a shaft. The tool includes a housing having a cylindrical wall with a plurality of perforations therethrough and an interior chamber therein. A removable cylindrical filter surrounds the interior chamber of the housing in order to filter solid particles. At least one centralizer bearing within the interior chamber of the housing centralizes the shaft which passes therethrough. The fluid in the interior chamber is radially induced in order to separate gas from fluid. The gas separated from the fluid is directed out of the chamber while the fluid remaining in the interior chamber is directed to the intake of the downhole pump.
