[0002] A choke manifold is an essential device for controlling well kicks and implementing oil and gas well pressure control technology. Under the condition that the blowout preventer is closed, by opening and closing the throttle valve, a certain casing pressure is controlled to maintain the bottom hole pressure slightly greater than the formation pressure at all times, preventing further inflow of formation fluids into the well.

[0003] After retrieval, it is found that a typical choke manifold in the prior art is, for example, a cryogenic-resistant choke manifold integration system with the publication number CN109931006A. At the upper and lower ends of the four-way joint on the left side, a material pipe, a flange, a flat valve, and a fine throttle valve are sequentially connected to form one long side of a "day"-shaped frame. On the right side of the four-way joint, a manifold pipe, a flange, a flat valve, and another four-way joint are sequentially connected to form the middle horizontal side of the "day"-shaped frame. On the upper and lower sides of the four-way joint on the right side, a flat valve, a flange, a manifold pipe, and a tee joint are sequentially connected to form the other long side of the "day"-shaped frame. Heat sinks are provided in the inner cavities of the material pipe and the manifold pipe on the side of the flange away from the flat valve. Second pvdf diaphragms are provided on the inner cavity side walls of the material pipe and the manifold pipe at one end of the heat sink away from the flange. First pvdf diaphragms are hinged to the inner cavity side walls of the material pipe and the manifold pipe opposite to the second pvdf diaphragms. The present invention has the characteristics of simple structure, good cryogenic resistance effect, and extended service life of the choke manifold.

[0004] In summary, for the existing choke manifolds, when in use, due to the impact generated when liquids such as oil in the pipeline erupt, it will have a certain impact on the mounting brackets, and when the use time is too long, the mounting brackets will become loose, without a good damping effect.

[0024] Compared with the prior art, the beneficial effects of the present invention are: the throttling manifold with adjustable throttling fixed oil nozzle,

[0025] (1) When the existing throttle manifold of the present invention is in use, a certain impact force will be generated when the oil or other liquid in the pipeline is sprayed, which will have a certain impact on the mounting bracket.
