Description
Technical Field

Background
With the progress of petroleum exploration technology, global marine oil and gas resources are gradually explored and discovered, and the currently discovered marine oil and gas resources exceed land oil and gas resource reserves. The development of marine oil and gas resources has become an important area affecting the world's oil and gas resource patterns.
The development of the ocean oil and gas resources is not separated from the ocean drilling platform type devices. However, the ocean drilling platform devices are often limited in arrangement area of each working area due to high manufacturing cost and other factors, and are controlled according to cost and design optimization.
Choke manifold is an important well control equipment in the drilling operation process, and for an ocean drilling platform, the functional structure requirement of the choke manifold is more complex than that of a land manifold. If a planar design is adopted according to the prior manifold design technology, a large amount of planar area is occupied. For example, chinese patent publication No. CN 205297363U discloses a ground throttle manifold arranged horizontally, which is divided into three channels, a main channel and two throttle channels, wherein one throttle channel is a fluid, the flow of which is regulated by an adjustable throttle valve, a flat valve control switch is arranged in front of and behind the adjustable throttle valve, the other throttle channel is a fixed throttle valve, the flow of which is regulated by a nozzle tip, a flat valve control switch is arranged in front of and behind the fixed throttle valve, an erosion protection nipple at the downstream of the throttle valve reduces the erosion of the throttled fluid to the valve, and the nozzle tip device is arranged in the fixed throttle valve body, including an inlet end and an outlet end, the outlet end extends out of the fixed throttle valve body and extends into the erosion protection nipple to be connected with the erosion protection nipple. The throttle manifold of this scheme is installed on ground, has adopted the horizontal plane's arrangement mode, but if install at ocean drilling platform will lead to taking up a large amount of areas, increase cost.
The prior patent literature also discloses a scheme for vertically arranging a choke manifold, for example, chinese patent with the authority of CN 201627567U discloses a marine vertical choke manifold, which comprises a welding neck flange, a manual flat valve, an anti-vibration pressure gauge, a mounting plate, a right-angle stop valve, a hydraulic choke valve, a four-way I, a manual flat valve B, a three-way I, a blind flange, a four-way II, a pressure gauge, a plug, a manual choke valve three-way II and a welding neck flange B, wherein the manual flat valve B, the anti-vibration pressure gauge and the right-angle stop valve are arranged on the three-way II, the three-way II and the blind flange are arranged on the four-way II, and one end of the three-way is provided with the manual flat valve A and the welding neck flange A. This scheme adopts vertical structure, is equivalent to carrying out vertical setting with horizontal plane structure, though can reduce occupation horizontal plane area, has increased vertical area's occupation, consequently, whole area does not reduce, and still has unstable risk in marine environment owing to vertical high promotion.
Therefore, how to control the manufacturing cost of a choke manifold in an ocean drilling platform and adapt to the ocean environment is a technical problem that needs to be considered by those skilled in the art.
