Abstract
The present invention relates to an intelligent switching valve for reservoir reformation and production monitoring and control. The intelligent switching valve comprises a connection short section, an electric short section, a fluid storage short section, a hydraulic control short section and a slide sleeve short section. The middle part of the intelligent switching valve is a full bore. In a working process, a casing coupling and a casing are connected and are mounted under the shaft as components of a well cementation casing. Wireless communication with ground equipment is realized through low-frequency electromagnetic waves to finish receiving/transmitting of working instructions and data. The switching valve is opened and closed under electric and hydraulic control and external assisting is not needed in an opening or closing process. The number of times of opening and closing is not limited and the number of stages is not limited.
