Description
Technical field
The present invention relates to single well metering device for oil well field more particularly to a kind of oil well gas fractionation units.
Background technique
Currently, when the major petroleum metering oil well output in China by the way of closing multiple wells and opening individual well metering yield,
This method influences other oil wells when measuring well yield and normally produces, and crude output is caused to reduce.
Summary of the invention
In view of the foregoing drawbacks or insufficient, the purpose of the present invention is to provide a kind of oil well gas fractionation units.
The technical solution of the present invention is as follows:
Enter short circuit, gas-liquid separating box, float, hanging barrier, seal receptacle, exhaust pipe, drain pipe, ball-and-seat, liquid including gas-liquid
Flowmeter body, gas flowmeter, gas-liquid mixed pipe composition are equipped with seal receptacle and float in gas-liquid separating box upper end, described floating
Sub- lower end is provided with spring, and the spring other end is fixedly installed in hanging barrier bottom, and the lower end and float upper end of seal receptacle seal,
The lower end of gas-liquid separating box is connect with drain pipe, and the gas-liquid of oil well output is after gas-liquid separating box separates, seal receptacle when gas is few
It is in sealing state with float, the sealing of seal receptacle and float is opened gas and is discharged from exhaust pipe when gas is more, and liquid is through gas
The drain pipe of liquid/gas separator lower end is discharged, and the gas-liquid enters short circuit inlet and is equipped with drying device.
Air gauge is installed on the exhaust pipe.
The invention has the benefit that
Oil well gas fractionation unit in oil well of the invention is equipped with seal receptacle and float, sealing in gas-liquid separating box upper end
The lower end and float upper end of seat seal, and the lower end of gas-liquid separating box is connect with drain pipe, and the gas-liquid of oil well output is through gas-liquid separation
After case separation, seal receptacle and float are in sealing state when gas is few, and when gas is more, gas is opened in the sealing of seal receptacle and float
Body is discharged from exhaust pipe, and liquid is discharged through the drain pipe of gas-liquid separator lower end.It can with one-well metering, gas-liquid when oil well production
Separately metering, it is easy to operate, manageability, saving of labor, time saving, safe and reliable.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
The present invention will be described in detail with reference to the accompanying drawing.
As shown in Figure 1, the present invention provides a kind of oil well gas fractionation unit, including gas-liquid enters short circuit 1, gas-liquid separation

Mixing tube 11 is formed by mechanism, and 2 upper end of gas-liquid separating box is equipped with seal receptacle 5, and gas-liquid separating box 2 is provided with hanging barrier 4, hanging barrier 4
It is provided with float 3,3 lower end of float is provided with spring, and the spring other end is fixedly installed in 4 bottom of hanging barrier, on float 3
End is sealed with 5 lower end of seal receptacle, and drain pipe 7 is connect with the lower end of gas-liquid separating box 2, and the end of drain pipe 7 is connected with ball-and-seat 8
It connects, the end of ball-and-seat 8 is equipped with fluid flowmeter 9, and the end of fluid flowmeter 9 is connected with gas-liquid mixed pipe 11, exhaust
The middle part of pipe 6 is equipped with gas flowmeter 10, and one end of exhaust pipe 6 is connect with 5 upper end of seal receptacle, the other end and gas-liquid mixed pipe 11
It is connected, the gas-liquid enters short circuit inlet and is equipped with drying device.
The course of work of the present invention:
The gas-liquid of oil well output is after gas-liquid separating box separates, and seal receptacle and float are in sealing state when gas is few, when
The sealing of seal receptacle and float is opened gas and is discharged from exhaust pipe when gas is more, and liquid is arranged through the drain pipe of gas-liquid separator lower end
Out.
