Gravel pack screen having retention mesh support and fluid permeable particulate solids

摘要: An apparatus is provided for use on a subterranean well conduit. The comprises cylindrically shaped inner tubular member having an interior and exterior walls. A fluid flow passageway within the wall passage extends from of through in communication with passageway. Retention mesh means are disposed around pass across openings therethrough, retention preventing particulate solids permeable bed passing into solids, such as sand, bauxite, glass beads, or like, placed sized to prevent effectively all matter inwardly when conduit positioned well. housing said has passages therethrough which permit production fluids interiorly but exteriorly
