ABSTRACT:
A flow choke filter for use with oil and gas wells wherein the flow choke has a sized passage for restricting fluid flow from a well and is seated in a housing that has an inlet for conducting well fluids to the inlet of the sized passage and an outlet for discharging well fluids from the flow choke sized passage and the housing, said filter having an elongated hollow body which is closed at one end and open at the other end. The hollow body is provided with an exterior surface in which recesses are formed with a longitudinally extending space between the recesses, such longitudinal space forming a surface between each recess which projects outwardly relative to the recesses in the body. A plurality of openings are provided in the bottom of the recesses for receiving flow from the well and conducting into the hollow body. Surface means on the hollow body sealably engages and positions the open end of the body to communicate with the sized passage of the flow choke so that fluid flow from the well is first conducted through the recess openings then to the sized passage in the flow choke.
