Description

Technical Field

[0001] The utility model relates to the technical field of well control throttle pipelines, and particularly relates to a high-temperature and high-pressure adaptation structure of a choke manifold. Background Art

[0002] At present, the use of choke manifolds in the drilling field is very common. During the well control process, it is often necessary to control the flow of various fluids in the well or change the flow route, which requires the choke manifold to achieve this purpose. The kill operation is mainly implemented through the throttling effect of the throttle valve to replace the contaminated mud in the well. At the same time, the casing pressure and riser pressure at the wellhead are controlled to restore the pressure control of the mud column on the bottom hole, stop the overflow, and reduce the inlet casing pressure through the pressure relief effect of the throttle valve. Protect the blowout preventer group at the wellhead through the large-scale drainage effect of the blowout valve.

[0003] According to the different well conditions of each well site currently, the requirements for the composition structure and use functions of the choke manifold will also be different. For some current well sites with relatively low well depth, unclear well conditions, and low well pressure, the current choke manifold cannot meet the usage requirements of the current well site, resulting in low applicability of the manifold. Moreover, the current choke manifold has a complex structure and a large size, not only with high usage costs, but also inconvenient for transportation;

[0004] The existing patent (publication number: CN219220364U) discloses a choke manifold, which consists of a first flat gate valve, a reducing cross, a second flat gate valve, a third flat gate valve, a fourth flat gate valve, a buffer steel pipe, an adjustable throttle valve, and a fifth flat gate valve to form the choke manifold structure, making the manifold structure have the functions of blowout and throttling, with complete functions, capable of meeting various working conditions during the drilling of low-pressure and low-production wells, enabling it to meet the usage requirements. At the same time, the manifold structure is simple, with low manufacturing costs and a small volume, capable of adapting to the narrow working space of the well site, and also convenient for transportation. Moreover, the manifold is provided with multiple spare ports, which can be connected to pipelines in multiple directions, with flexible use and convenient maintenance.

[0005] Regarding the above problems, the existing patent gives a solution, but it is not convenient to reduce the temperature of the pipeline. During long-term operation, the temperature of the pipeline rises, which will not only cause the seals to age and deform, reducing the sealing performance, but may also affect the strength and stability of the pipeline material, reducing the service life of the manifold, causing safety problems such as leakage, affecting the drilling efficiency, and reducing the practicality of the device.

[0006] Therefore, a high-temperature and high-pressure adaptation structure of a choke manifold is proposed. Summary of the Utility Model

During long-term operation, the temperature of the pipeline rises, which will not only cause the seals to age and deform, reducing the sealing performance, but also may affect the strength and stability of the pipeline material, reducing the service life of the manifold, causing safety problems such as leakage, affecting the drilling efficiency, and reducing the practicability of the device.

[0032] In this embodiment: By the combined use of the infusion pump 302 and the infusion tube 303, the coolant inside the liquid storage tank 301 can flow smoothly into the inner layer 5. At the same time, under the action of the reflux tube 305, the coolant inside the inner layer 5 can flow back into the liquid storage tank 301, realizing the recycling of the coolant, improving the smoothness of the coolant flow, and under the action of the cooling device 304, the temperature of the coolant inside the liquid storage tank 301 can be reduced, so that the temperature of the liquid inside the connecting tube 1 can be continuously reduced, avoiding potential safety hazards caused by overheating of the connecting tube 1, effectively ensuring the safe and stable operation of the device, and improving the service life of the device.
