INTERVAL CONTROL VALVE WITH VARIED RADIAL SPACINGS

摘要

A flow control device for use with a subterranean well, can include inner and outer flow trim sleeves. A radial spacing between the inner and outer flow trim sleeves increases in a direction of flow through the radial spacing. A method of regulating flow between an interior and an exterior of a tubular string in a well can include displacing at least one of inner and outer flow trim sleeves in a direction, a radial spacing between the inner and outer trim sleeves increasing in the direction. Another flow control device can include inner and outer flow trim sleeves, and a flow area through the radial spacing increases in a direction of flow through the radial spacing.
