MPD Equipment and Technology
Managed pressure drilling (MPD) is an advanced drilling technique used in the oil & gas industry to precisely control annular pressure throughout the wellbore. The key equipment of MPD including choke manifold and RCD. The choke manifold and RCD equipped in the MPD equipment developed and manufactured by Heminzenith are both fully electronically controlled.

Data Monitoring and Control Systems
One of the supporting equipment for the automatic choke manifold is primarily used for receiving real-time data from mud logging and the automatic choke manifold, monitoring and analyzing these data. Based on data models, it provides real-time warnings for downhole conditions and issues commands to the automatic choke manifold through the choke manifold control system of this center, thereby enabling real-time control of the surface casing pressure.
Externally Mounted: Explosion-proof surveillance camera, used for observing the operation status of the rotary control head at the wellbore and the condition of the ignitor.
Internally Installed: Detecting and early warning software, automatic choke manifold control software, video recording software, etc.
