With the development of carbonate fractured oil and gas reservoirs, drilling projects have high-risk working conditions. The wellhead device needs to be more reasonably matched and complete to meet the 140MPa ultra-high pressure working condition, and meet the needs of simultaneous testing of multiple wells on the shale gas factory platform to achieve multi-channel access and multi-process processing functions for a single manifold. By monitoring the pipeline pressure, flow rate, temperature, etc., and feeding back to the control cabinet, it can be remotely and automatically identified and controlled, which is safe and reliable. It can also accurately adjust the pipeline pressure and flow at any time, and can be fed back to the control cabinet for automatic control in real time.
