10000 Psi Custom Choke And Kill Manifold For Oil And Gas Well Pressure Balancing

________________________________________

Product Description:

The throttle well-killing manifold produced and sold by our company Huichi petro is an indispensable key equipment for controlling well kicks and implementing oil and gas well pressure control in oil drilling operations. The equipment implements well-killing operations through the throttling effect of the throttle valve, controls the wellhead casing pressure and riser pressure, restores the control of the bottom hole mud column on the bottom hole pressure, and effectively stops overflow. At the same time, the throttle well-killing manifold also has the function of large-scale discharge through the blowout channel, reducing the wellhead casing pressure and protecting the wellhead blowout preventer group.

‌Product Composition‌:

The throttle well-killing manifold produced and sold by our company Huichi petro is mainly composed of throttle valves, flat valves, five-way valves, manifolds, buffer pipes, pressure gauges, and remote control boxes. The hydraulic throttle manifold is also equipped with advanced control components such as hydraulic control boxes, valve position transmitters, and pneumatic pressure transmitters to achieve remote and precise control.

1. Choke manifold

• Throttle valve: core component, usually adopts needle valve structure, by finely adjusting the valve opening, it can achieve precise control of drilling fluid flow, and then adjust the wellhead back pressure and balance the pressure in the well. Its material is mostly high-strength alloy steel, with good wear and corrosion resistance, and can adapt to high temperature, high pressure, high sulfur and other harsh working conditions.
• Flat valve: installed before and after the throttle valve, used to cut off or conduct the drilling fluid flow channel. The flat valve has good sealing performance, flexible opening and closing, can withstand high pressure, and plays an isolation role when the throttle valve is repaired or replaced to ensure safe operation.
• Pipeline and connector: It is composed of high-strength seamless steel pipes and various pipe fittings, connecting various components to form a complete fluid channel. The pipeline is designed with a high pressure resistance level and can withstand the high pressure that may occur at the wellhead. The connector adopts a sealing structure to ensure the sealing of the entire manifold system.

2. Well-killing manifold

• Well-killing pump: provides power for well-killing operations and injects well-killing fluid into the well at a certain pressure and flow rate. Usually, plunger pumps or centrifugal pumps are selected, which have the characteristics of large flow and stable pressure, and the injection parameters can be accurately adjusted according to the situation in the well.
• Check valve: prevent the backflow of well killing fluid to ensure the smooth progress of well killing operation. The one-way valve has reliable sealing performance and can effectively prevent the reverse flow of fluid under high pressure to ensure the safety of the well killing system.
• Other components: including pressure gauges, stop valves, etc., which are used to monitor the pressure of well killing fluid and control the flow direction and flow of well killing fluid.

Working principle:

1. Throttling principle: When the wellhead pressure increases, by adjusting the throttle valve opening, the drilling fluid will produce a throttling and pressure reduction effect at the throttle valve, and the wellhead back pressure will increase, thereby balancing the pressure in the well and preventing the formation fluid from further flowing into the wellbore. The operator can adjust the throttle valve opening in real time according to the change of wellhead pressure to achieve dynamic control of the well pressure.
2. Well killing principle: When abnormal situations such as well kick or blowout occur, high-density well killing fluid is injected into the well through the well killing manifold to increase the pressure of the liquid column in the wellbore to make it greater than the formation pressure, thereby restoring the pressure balance in the well and stopping the blowout. During the well killing process, the displacement and pressure of the well killing pump and the switch status of each valve are adjusted to ensure that the well killing fluid is injected into the well evenly and stably.

Product features:

1. High performance: The working pressure range of the throttle well killing manifold is wide, ranging from 2000Psi to 20000Psi, meeting the needs of different drilling operations. At the same time, its nominal diameter ranges from 2-1/16″ to 4-1/16″ (52mm～103mm), which is suitable for the circulation of various drilling fluids and muds.
2. Safe and reliable: The throttle manifold meets the requirements of API Spec 16C standard. The threaded connection is in line with international standards and can be interchanged with similar products at home and abroad; all valves are made of anti-sulfur, corrosion-resistant and erosion-resistant materials, and the key components have undergone strict quality inspection and performance testing, with good sealing and easy switching. The throttle valve and flat valve are flexible to operate and can be controlled by manual, hydraulic or pneumatic methods, which is convenient for operators to quickly adjust under different working conditions. At the same time, the manifold is reasonably laid out, and the components are clearly marked, which is convenient for operation and maintenance.
3. ‌Remote control‌: Equipped with a remote control box, the operator can accurately control the throttle well-killing manifold at a safe distance to improve the safety and efficiency of operations.
4. ‌Versatility‌: The throttle well-killing manifold can not only be used to control well kicks and well-killing operations, but also can be used to discharge a large amount of flow through the blowout channel during blowouts, protect the wellhead blowout preventer group, and reduce accident losses.
5. Wide adaptability: It can be customized according to different drilling processes and geological conditions to meet the throttle well-killing needs of various types of oil and gas wells, whether it is land drilling or offshore drilling.
