Oilfield Well Testing Choke Kill Manifold 2 1/16 Inch 3000psi
The choke manifold is a necessary tool for effectively controlling the well kick and implementing pressure control technology on oil and gas wells during drilling. Currently, the tool is used to implement a new drilling technique called pressure balancing, which can prevent oil layer pollution, increase drilling speed, and effectively control blowout. The device is attached to the BOP spool's side flange on one end. By modifying the choke valve's opening when BOP closes, it may regulate the limited pressure from the casing, allowing balanced drilling to operate with the least amount of pressure differential.

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 to control casing pressure, which can be directly blown out through the gate valve if the casing pressure is quite high.
4. Pressure Ratings
The kill manifold is available in pressure ratings of 2000psi,3000psi,5000psi,10000psi, and 15000psi, and also can be available upon customer request.
Operating Instructions
(1) The working pressure of all components on the choke manifold shall be compatible with that of the BOP stack used.
(2) The choke manifold shall be installed at a place where the operator can reach it easily. The pressure test must be performed before installation and the seat test pressure shall be equal to the rated working pressure.
(3) The line pipe shall be level and straight as much as it could. In case of the turn of the line pipe, the 120-degree steel bent pipe shall be used. The bore of the line pipe shall be large enough.
(4) The pressure gauge must be installed.
(5) In winter, the choke manifold can work under a low-temperature conditions.
