◆ Product introduction ◆
? choke manifold is mainly used to control kick and implement pressure control of oil and gas wells; When the BOP is closed, use the opening and closing of the throttle valve to control a certain casing pressure to maintain the bottom hole pressure slightly higher than the formation pressure, so as to prevent the formation fluid from further flowing into the well.
? during well shut in, the choke manifold can be used to relieve pressure to achieve soft shut in. When the pressure in the well rises, the fluid in the well can be released by opening and closing the throttle valve (manual adjustable, hydraulic and fixed) on the choke manifold to control the casing pressure. When the pressure in the well rises to a certain limit, it can be used to blowout to protect the wellhead.
? choke manifold is an important equipment in well killing operation. Through the pressure relief effect of choke valve, the wellhead pressure can be reduced to achieve soft shut in. Reduce the wellhead casing pressure, protect the wellhead blowout preventer group, and lead the overflow in the well out of the well pad through the diversion and blowout of the throttle valve.
