Choke Manifold

Cart

A choke manifold is an arrangement of piping and valves with adjustable choke valves. This assembly is primarily responsible for controlling flows and pressures in various industrial applications, such as onshore and offshore well testing and production operations. By implementing a choke manifold, operators and asset owners can adjust the flows and pressures that enter processing equipment, thus controlling production and minimizing equipment damage.

product details

Choke Manifold is a necessary equipment for controlling well kick and implementing pressure control technology in oil and gas wells. Under the condition of the blowout preventer being closed, the opening and closing of the throttle valve is used to control a certain casing pressure to maintain the bottom pressure slightly higher than the formation pressure, avoiding further inflow of formation fluids into the well. In addition, when implementing well shut in, a pressure relief manifold can be used to achieve soft shut in. When the pressure inside the well reaches a certain limit, it is used to release water to protect the wellbore.
