发明名称 Bidirectional Flow Control Device for Facilitating Stimulation Treatments in a Subterranean Formation
摘要 Bidirectional flow control device for attachment to a tubular member including a nozzle insert comprising a first sealable surface, the nozzle insert comprising a nozzle passage, and a second sealable surface for mating with the first sealable surface, and a first biasing member seat; a cover plate positioned adjacent the first end of the nozzle insert, the cover plate comprising a production orifice and a plurality of stimulation orifices in fluid communication with a plurality of stimulation passages, the cover plate further comprising a second biasing member seat and a biasing member positioned between the first biasing member seat and the second biasing member seat, the biasing member to exert a biasing force to place first sealable surface and second sealable surface in sealing engagement when internal tubular pressure is below a set-point value.

主权项 1. A bidirectional flow control device for attachment to a tubular member, the tubular member defining an internal flow passage, comprising: (a) a nozzle insert comprising a first end and a second end, the nozzle insert axially positionable within a bore, the bore in fluid communication with the internal flow passage of the tubular member and comprising a first sealable surface, the nozzle insert comprising a nozzle passage in fluid communication with the bore, and a second sealable surface for mating with the first sealable surface, and a first biasing member seat; (b) a cover plate positioned adjacent the first end of the nozzle insert, the cover plate comprising a production orifice in fluid communication with the nozzle passage of the nozzle insert and a plurality of stimulation orifices, the plurality of stimulation orifices in fluid communication with a plurality of stimulation passages, the stimulation passages in fluid communication with the bore, the cover plate further comprising a second biasing member seat; and (c) a biasing member, the biasing member positioned between the first biasing member seat and the second biasing member seat, the biasing member structured and arranged to exert a biasing force sufficient to place first sealable surface and the second sealable surface in sealing engagement when the internal tubular pressure is below a set-point value.
