Using fiber grating sensing technology and devices and to achieve a downhole flow control valves without interference signal transmission

Since the microcontroller slice mining technology began to use flow control system for traffic control, significantly increased the rate of oil extraction. In this context, for the precise control and information flow can not interfere with a serious problem,  Instrument valve manifolds  a fiber grating based sensing downhole flow control valve opening detection system. The system uses fiber optic sensing technology and devices, and to achieve a downhole flow control valves  Stainless steel needle valve  signal transmission, can also get traffic information in real time underground, reducing the traditional routine operations. Introduces the research status of downhole flow control valves, flow made ​​using fiber grating detection methods.
