Abstract

The invention relates to the technical field of wellhead Christmas tree devices, in particular to a self-sealing adjustable corrosion-resistant wellhead Christmas tree device. The device comprises an oil extraction base, wherein a large four-way joint is fixedly connected to the upper end of the oil extraction base, flange plates are arranged on the two sides and the upper end of the large four-way joint, the flange plates located on the two sides of the large four-way joint are fixedly connected with a first gate valve and an oil drainage gate valve correspondingly, a first safety valve and an oil drainage safety valve are arranged on the opposite sides of the first gate valve and the oil drainage gate valve respectively, a screwed plug is fixedly arranged on the other side of the first safety valve, an oil drainage pipe is fixedly arranged on the other side of the oil drainage safety valve, and an oil drainage pressure gauge is fixedly arranged on the oil drainage gate valve. The device is stable in structure and resistant to corrosion, has the advantages of automatic opening and closing, is simple and easy to replace a throttle valve, is capable of automatically adjusting the oil production, saves time, and does not affect the oil production.

Description

technical field [0001] The invention relates to the technical field of wellhead Christmas tree devices, in particular to a self-styled adjustable corrosion-resistant wellhead Christmas tree device. Background technique [0002] The wellhead Christmas tree assembly is an assembly located at the opening to the top of the oil well, including valves for measurement and maintenance, safety systems and a series of monitoring instruments. The wellhead Christmas tree device connects the production pipeline and the oil flow pipe from the downhole, and at the same time serves as an important barrier to isolate the top of the oil well from the external environment. It includes a number of valves that can be used to regulate or stop the gushing of produced crude oil vapor, natural gas and liquids from the well. The wellhead Christmas tree device is connected to the production manifold system through subsea pipelines. [0003] The traditional wellhead Christmas tree device generally la...
