Choke manifold is the necessary device to control the well kick successfully and execute the pressure control technology on oil /gas well in the drilling, It is adopted to execute new drilling well’s technique of balance pressure, which can prevent the pollution of oil-layer, improve the speed of drilling and control blowout effectively. One end to connect 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 balanced drilling can work under minimum pressure-difference.
When the pressure rise 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 as the casing pressure is quite high.
Pressure level is divided into five levels, i.e. 2,000psi, 3,000psi, 5,000psi, 10,000psi, 15,000psi;
Fabrication of choke manifold is according to the requirements of API spec 16C.
Working pressure: 2,000psi - 15,000psi; Nominal bore size: 2.1/16” to 4.1/16”
