Adjustable wellhead Christmas tree device

Abstract

The invention discloses an adjustable wellhead Christmas tree device, which relates to the technical field of Christmas tree pipeline adjustment, and comprises a bottom plate, an oil extraction pipe body, an upper end main valve, a lower end main valve, a secondary wing valve, a main wing valve, a throttle valve, an oil drawing valve and a pressure test meter, by rotating the rotating wheel on the oil extraction pipe body, the clamping column drives the second round cover to move up and down in the first cylindrical cover, petroleum is controlled to flow into the main wing valve and the secondary wing valve, and when the steel ring stabbing leakage problem occurs on the side, close to the oil extraction pipe, of the main wing valve, the first channel on the first cylindrical cover can be closed by rotating the rotating wheel; compared with a traditional means of closing the main valve at the upper end, the device enables the Christmas tree to work continuously, meanwhile, maintenance of the main wing valve can be achieved, oil exploitation cannot be affected, and the oil exploitation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of oil tree pipeline adjustment, in particular to an adjustable wellhead Christmas tree device. Background technique [0002] The Christmas tree is also called the Christmas tree; it is a wellhead control device when testing oil and gas after the completion of the oil (gas) well, or when producing oil from blowout wells and machine production wells; it is hung by tubing and many gates and tee or four It is directly installed on the casing head. Only one side of the tree with the oil outlet pipe is called the single-wing tree; Oil and gas production is controlled by changing nozzles with different inner diameters. [0003] like figure 1 The marked position a shown is at the connection position between the wing valve and the three-way pipe. Since one end of the wing valve is connected with a throttle valve, the oil flows in the pipeline for a long time, which will cause the inner clamp steel at the connectio...

AI Technical Summary

Problems solved by technology

[0009] 1. By turning the runner on the oil production pipe body, the clamping column drives the second round cover to move up and down in the first cylindrical cover, so as to realize the control of oil flow into the main wing valve and the secondary wing valve, and solve the problem of the valve pipeline on one side. Problems requiring closure of the entire main valve;

[0010] 2. By rotating the knob, the first movable rod, the load-bearing rod and the second movable rod are rotated to realize the clamping and fixing of the oil production pipe body by the clamping block, which solves the problem of manual lifting and lowering of the valve pipe on the oil tree. When disassembling, multiple workers are required to manually fix it, which is likely to cause injury to the staff and increase the maintenance cost of the Christmas tree.
