Abstract
Et skaderesistent filter for anvendelse i underjordiske brønner har minst ett lag av et filtermedium (13), så som en sintret, understøttet porøs membran, koaksielt anbrakt rundt et perforert bærerelement (11). Filteret kan også innbefatte et dreneringslag (15), anbrakt mellom det indre bærerelemen- tet og filtermediet, og et beskyttende dekke, så som et perforert bur (17) som omgir filtermediet (13). Filteret er spesielt egnet for fjernelse av sand og andre partikkel- formige materialer fra fluidene produsert i en brønn.
