Description
Technical Field
The utility model relates to an oil field chemistry technical field, concretely relates to well head device suitable for plunger gas lift drainage gas production.
Background
In the natural gas exploitation process, underground water permeates into a gas well in the later gas exploitation stage, plunger gas lift drainage is a common drainage process, and the plunger gas lift drainage is mainly used for pushing a plunger in an oil pipe to lift a water column by using the self energy of the natural gas well so as to achieve the purpose of drainage. It does not need power equipment, and the drainage cost is low, can also avoid gaseous invalid consumption.
The working principle of plunger gas lift drainage is as follows: the plunger falls into buffer upper portion by the dead weight, during the drainage, under the gaseous pressure in the cover pipe, in stratum water gets into the oil pipe, promotes the plunger simultaneously and goes upward, along with the discharge of stratum water, the plunger goes upward to the mouth of pipe gradually, and when the tolerance was not enough, the plunger was gone downward to the buffer, accomplishes a drainage cycle promptly. However, the plunger is a quick-wear part, so that the service life cycle is short, and the existing plunger gas-lift drainage device has the problem that the plunger is inconvenient to take out.

Detailed Description
In order to clearly understand the technical features, objects and advantages of the present invention, the following detailed description is given to the technical solution of the present invention, but the technical solution of the present invention is not limited to the limit of the implementable range of the present invention.
Example (A)
Example 1
A wellhead device suitable for plunger gas lift water drainage gas production, comprising:
the tube body (1) is provided with a plurality of grooves,
specifically, the bottom of the pipe body 1 is provided with a flange for connecting with a gas production tree; pipe main part 1 from the bottom up still is equipped with stop valve 3, branch pipe 4 and ultrasonic sensor 5, and wherein, branch pipe 4 and ultrasonic sensor 5 all can set up a plurality ofly, and stop valve 3 is used for cutting off the fluid circulation in the pipe main part 1, and branch pipe 4 is used for being connected with drain pipe or gas production pipe, and ultrasonic sensor 5 is used for detecting the position of plunger.
Specifically, 2 body inner walls of plunger extraction portion are equipped with one deck cushion 7, the edge of cushion 7 is fixed with the inner wall of plunger extraction portion 2, rotor plate 8 is located between cushion 7 and the body inner wall, 8 one end of rotor plate is connected with the inner wall rotation of plunger extraction portion 2, when opening control valve 6, rotor plate 8 rotates, drive cushion 7 from this and draw 2 inboard expansions to the plunger, thereby reduce the internal diameter of 2 lower extremes of plunger extraction portion, avoid the plunger to pass through in 2 return pipes main parts 1 of plunger extraction portion.
The plunger extraction part 2 is a horn-shaped pipe body, the opening angle of the horn-shaped pipe body is 1-10 degrees, and the angle is adopted mainly because the volume of the upper part of the plunger extraction part is too large if the angle is too large, so that space and materials are wasted, and waste is generated. In the present embodiment, the opening angle thereof is set to 4 °.
In order to reduce the corrosion of the formation water to the rotating plate 8, the width of the elastic pad 7 is larger than that of the rotating plate 8, and meanwhile, the elastic pad 7 completely covers the rotating plate 8, so that the rotating plate 8 can be protected to the maximum extent, and meanwhile, corrosion-resistant rubber is adopted as the elastic pad 7, so that the corrosion of the formation water to the elastic pad can be avoided.
In this embodiment, the control valve 6 is provided at the joint of the plunger extraction portion 2 and the pipe body 1, and a blowout preventer cap 9 is further provided on the upper portion of the plunger extraction portion 2.
In this embodiment, in order to more accurately monitor the position of the plunger so as to timely start the control valve 6, the ultrasonic sensor 5 is disposed on the top of the tube body 1, and after it is detected that the plunger integrally passes through the ultrasonic sensor 5, the control valve 6 is timely started by combining the time when the plunger passes through the ultrasonic sensor 5 and the length of the plunger.
The present invention has been disclosed in the foregoing in terms of preferred embodiments, but it will be understood by those skilled in the art that these embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of the invention. Under the prerequisite that does not deviate from the utility model discloses the principle, it is also to regard as the utility model discloses a further improvement is in the protection scope.
