Choke and Kill Manifold

Choke manifold control kicks , to implement the necessary equipment and gas well pressure control technology . Under the BOP closing conditions, the use of the throttle valve opening and closing, the control pressure to maintain a certain set of bottomhole pressure is always slightly larger than the formation pressure , to avoid further inflow of formation fluid wells . Also in the implementation shut , can choke manifold pressure relief in order to achieve a soft shut . When the well pressure rises to a certain limit, through which to put spray to protect the wellhead . When the well pressure increases, through the throttle on the choke manifold (with manual adjustable , hydraulic and fixed three ) on and off to release the well fluid to control casing pressure . Spray can be placed directly through the gate when the set pressure is high.
