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-wells technique of balance pressure,which can prevent the pollution of oil-layer, improve the speed of drilling and control blowout effectively.
Production standard: API16C
Nominal Bore: 2 1/16”~4 1/16”
Working Pressure: 2000~20000psi
Product Specification Level: PSL1 ~ PSL4
Performance Requirement: PR1,PR2
Main features:
1. Assembly &structure
Choke manifold consists of choke valve,gate valve, pipeline,fittings and pressure gauge etc. 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.
2.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.
