 The existing hydraulic decoder mostly adopts the scheme of three hydraulic control pipelines to control up to six production layers, which increases the number of hydraulic decoders and pipelines, improves the complexity of pipeline logic and increases the technical difficulty when crossing the packer. Therefore, it is of great significance to innovate the control strategy and structure of hydraulic decoder to improve oil production efficiency and quality.
