API 16C Choke Manifold
It is the necessary device of controling overflow and blowout, enforcing oil and gas well pressure control technique. In the course of oil and gas well drilling, drilling fluid in the
borehole is surely to be polluted by resident fluid, then the balance between hydrostatic fluid column pressure of drilling well fluid and reservoir pressure will be broken, causing overflow and
blowout. When the polluted drilling fluid or hydraulic well whose pump performance is adjusted is cycled out so that the new balance can be achieved, the opening and close of choke valve to control
back pressure so that the pressure of well bottom can be maintained in the situation of closing blowout preventer. Besides, Flexible choke&kill device can be used to clean well etc.
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 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 balanced drilling can work under minimum
pressure-difference.
