1. Application

   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.

2. Assembly&structure

   Choke manifold consists of choke valve, gate valve, pipeline,fittings and pressure gauge etc.

3. Working principle

   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.

4. Choke manifold is according to the requirement of API Spec 16C

   Working pressure: 2000psi~20000psi.

   Nominal bore size: 2 1/16”~4 1/16”
