Abstract: A sand screen structure used to filter particulate matter from formation fluid entering a well bore is assembled from a plurality of generally tubular filter sections that may be axially snapped together in a manner facilitating the simultaneous interconnection of circumferentially spaced series of axially extending shunt tubes secured to and passing internally through each of the filter sections. By utilizing snap-fit interconnections between the filter sections, instead of conventional threaded connections, the assembly of the overall sand screen structure is made substantially easier and quicker, and the lengths of the blank, nonfiltering portions of the sand screen structure between its individual filter sections are substantially reduced. In an alternate embodiment of the sand screen structure the shunt tubes are secured within external side surface recesses of the filter section bodies.
