Description
Technical field
The utility model is related to a kind of gas lift valve, belongs to petroleum and natural gas well airlift unit technical field.
Background technology
Existing gas lift valve is by tail is stifled, upper valve body, bellows component, lower valve body, middle valve body, valve ball, valve seat, valve nozzle, single current
The parts such as valve assemble.It is arranged on special seating nipple, then couples seating nipple with oil pipe, tripping in Oil/gas Well after adapted
It is interior.In Oil/gas Well production process, gas lift valve can play the liquid level in reduction tubing string, and reduction fluid column is returned to shaft bottom
Pressure, the effect of stabilized hydrocarbon yield.
Existing gas lift valve is during the use of gas condensate field, because condensate gas well is accompanied by condensation in output natural gas
Oil.Condensate belongs to hydrocarbon mixture, when hydrocarbon mixture is in dissolved state, easily forms macromolecular mass.When condensation oil temperature
When being down to wax precipitation point, the hydro carbons macromolecular mass in condensate, which can be produced, crystallizes and is formed block wax.
Underground gas lift valve is after work is opened, and natural gas carries condensate and entered by gas lift valve valve nozzle and ball-and-seat in well
In tubing string.When natural gas takes condensate by gas lift valve valve nozzle, volume is first compressed；Then and drastically expand, this mistake
Journey along with pressure and temperature change.When temperature at gas lift valve valve nozzle is reduced to wax precipitation point, the hydrocarbon included in condensate
Class macromolecular mass will be separated out inside gas lift valve valve nozzle and ball-and-seat to be crystallized and gradually forms block wax, so as to block gaslift
Valve.
The content of the invention
The purpose of this utility model be overcome existing gas lift valve valve nozzle easily by the defect of the Crystallization Plugging in condensate there is provided
A kind of gas lift valve.
What the purpose of this utility model was realized in：
The utility model is made up of valve body, valve nozzle assembly, ball-and-seat, and screw thread connects successively for valve body, valve nozzle assembly, ball-and-seat
Connect, the lower end of ball-and-seat is provided with the sound wave nozzle of cupro-nickel rhenium alloys processing.
Described sound wave nozzle is tubular body, and upper and lower ends are machined with connection screw thread respectively, and its central through hole two ends is served as reasons
Tapering transition undergauge section outside to inside, drainage lumens, aditus laryngis and accelerating cavity are divided into by central through hole.
Described valve body includes air chamber, bellows, valve rod, valve ball, and the lower surface of air chamber is welded with bellows, bellows
Lower end is welded with valve rod, and the bottom of valve rod is welded with valve ball.
Described valve nozzle assembly is columnar structured, and the stomata being uniformly distributed along the circumference, upper end inwall are machined with the side wall of cylinder
Internal thread is machined with, lower end outer wall is machined with external screw thread, and inside is provided with cylindrical shape valve seat, and the center of cylindrical shape valve seat is provided with
Valve nozzle.
The beneficial effects of the utility model：When natural gas, which takes condensate, enters the drainage lumens of sound wave nozzle, gas is pressed
Contracting accelerates, and sound wave is produced during by the aditus laryngis of sound wave nozzle.The condensate liquid that sound wave is carried to gas produces shear action, makes
Condensate liquid becomes the less drop of diameter；When gas takes condensation oil drops into accelerating cavity, due to gas expansion, flow velocity adds
It hurry up, gas is taken condensation oil drops and entered at a relatively high speed inside tubing string, and reaching prevents condensate in gas lift valve valve nozzle and single current
Wax deposition inside valve, improves the purpose of gas lift efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is partial structural diagram of the present utility model.
Embodiment
From accompanying drawing 1, the utility model is made up of valve body 1, valve nozzle assembly 2, ball-and-seat 3, valve body 1, valve nozzle assembly 2,
Ball-and-seat 3 is threadedly coupled successively, and the lower end of ball-and-seat 3 is provided with the sound wave nozzle 4 of cupro-nickel rhenium alloys processing.
Described sound wave nozzle 4 is tubular body, and upper and lower ends are machined with connection screw thread respectively, and its central through hole two ends is served as reasons
Tapering transition undergauge section outside to inside, drainage lumens 12, aditus laryngis 13 and accelerating cavity 14 are divided into by central through hole.
Described valve body 1 includes air chamber 5, bellows 6, valve rod 7, valve ball 8, and the lower surface of air chamber 5 is welded with bellows 6,
The lower end of bellows 6 is welded with valve rod 7, and the bottom of valve rod 7 is welded with valve ball 8.
Described valve nozzle assembly 2 is columnar structured, is machined with the side wall of cylinder in the stomata 11 being uniformly distributed along the circumference, upper end
Wall is machined with internal thread, and lower end outer wall is machined with external screw thread, and inside is provided with cylindrical shape valve seat 9, the center of cylindrical shape valve seat 9
It is provided with valve nozzle 10.
After the completion of the utility model debugging, first it is installed on special seating nipple, then by special seating nipple and oil pipe
Be connected G.I.H；After condensate gas well opening well and making production, gas pressure acts on bellows 6 by stomata 11 in sleeve pipe, works as set
When gas pressure is more than the pressure of air chamber 5 to the active force of bellows 6 to the active force of bellows 6 in pipe, bellows 6 compressed to
Upper movement, the pull-up of valve rod 7, valve ball 8 leaves cylindrical shape valve seat 9, and valve nozzle 10 is opened, and gas carrying condensate passes through gas in sleeve pipe
Hole 11, valve nozzle 10, ball-and-seat 3, sound wave nozzle 4 enter oil pipe, now condensate and gas lift valve cylindrical shape valve seat 9 and ball-and-seat
3 produce contact, and because the material used in gas lift valve cylindrical shape valve seat 9 and ball-and-seat 3 is cupro-nickel rhenium alloys, the alloy has electricity
Chemism, can produce electrostatic catalytic action, the hydro carbons macromolecular mass in condensate is reduced and loose, when valve nozzle 10 and single current
When the temperature of valve 3 is down to wax precipitation point, though the hydro carbons macromolecular mass in condensate can keep dissolved state or have tiny crystals precipitation,
But it can be suspended in condensate；When natural gas take condensate enter sound wave nozzle 4 drainage lumens 12 when, gas by compression acceleration,
Sound wave is produced during by the aditus laryngis 13 of sound wave nozzle, the condensate liquid that sound wave is carried to gas produces shear action, makes condensation
Fluid body becomes the less drop of diameter, and when gas takes condensation oil drops into accelerating cavity 14, due to gas expansion, flow velocity adds
It hurry up, gas is taken condensation oil drops and entered at a relatively high speed inside tubing string, so that reaching prevents condensate in gas lift valve valve nozzle 10
With the inside wax deposition of ball-and-seat 3, the purpose of gas lift efficiency is improved；When gas pressure is higher than gas pressure in sleeve pipe in oil pipe, gas
Lifting the ball-and-seat 3 on valve body will close, and prevent the reverse channelling sleeve pipe of gas in oil pipe.
