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
execute new drilling-well’s technique of balance pressure, which
can avoid pollution of 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.
Configuration
The choke manifold consists of choke valves, gate valves, line
pipes, fittings, pressure gauges and other components.
Working Principles
When the pressure inside the well rises, opening/closing the choke
valves (including manual chokes, hydraulic chokes and positive
chokes) on the choke manifold can allow the release of the fluid
inside the well so as to control casing pressure, which can be
directly blown out through the gate valve if the casing pressure is
quite high.
Pressure Ratings
The kill manifold is available in pressure ratings of 14MPa, 21MPa,
35MPa, 70MPa and 105MPa, and also can be available upon customer
request.

Choke manifold and kill manifold are important well control
equipment in balancing pressure in near-balanced drilling wells
during petroleum exploration. Choke manifold controls the casing
pressure and maintains the balance inside the well, the soft
closing of the well is realized by relieving pressure through the
choke valve, through which the casing pressure can directly blow
out in order to protect the well.
Choke manifold consists of throttle valve, gate valve, pipeline,
pipe fitting, and pressure gauge, etc.
When it is pressurized inside the well, the pressure inside the
pipe can be controlled by adjusting the opening and closing of the
throttle valve (manual adjustable, hydraulic, and stationary) on
the choke manifold to release the liquid in the well. When the
casing burst pressure exceeding certain differential pressure, it
can open flow directly by the gate valve.
There are five pressure grades for the choke manifold made in our
company: 14MPa, 21MPa, 35MPa, 70MPa, 105MPa; we can design and
manufacture according to customers’ requirement.
