Well Control Equipment Choke Manifold for Oill Drilling Petroleum Equipment
Choke manifold is necessary device to control the well kick successfully and execute the pressure control technology on oil/gas well in the course of drilling, as it is, the device is adopted to the execute new drilling well's technique of balance pressure, which can prevent the pollution oil-layer,improve the speed of drilling and control blowout effectively. One end of the device connects with the side flange of BOP spool. When BOP closes, it can control the finite pressure from casing by adjusting the choke valve's opening, so balance drilling can work under the minimum pressure-difference.
Choke Manifold Control pressure to prevent overflow and blowout. Reduce wellhead casing pressure by relief function of choke valve. Full-bore and two-way metal seal Choke bean features hard alloy inside, delivering high resistance to erosion and corrosion. The relief valve helps to reduce casing pressure and protect BOP. Configuration type: single-wing, double-wing, multiple-wing or riser manifold Control type: manual, hydraulic, RTU Kill Manifold Kill manifold is mainly used to kill well, prevent fire and assist in fire extinction.
Choke manifold consists of four manual gate valves (also called diamont choke manifold, five gate valves if a bypass valve is included). It is used to control the flow rate and reduces well pressure before the flow enters the processing equipment. The maniflod also includes a positive choke box, an adjstable choke, and several pressure or sampling ports and thermowells to monitor pressure, temperature, and fluid characteristics.
When the pressure rising in well,fluid in well can be released in utilization of the choke valve opening/closing in choke manifold to control casing pressure, which can directly blow out through gate valve when the casing pressure is quite high.
