Installation set hook gauge 17.
Step 2, gaslift induced flow；Using the gas lift liquid drainage technique of routine, nitrogen or natural gas from sleeve pipe and oil pipe
Annular space is injected, and the water in well is discharged to ground, and is vented well head pressure, closes tubing valve 19 and sleeve valve afterwards
26。
Step 3, starter；In terrestrial operation catcher 25, plunger 7 is discharged, the plunger 7 in plunger damper 14 is in weight
Moved downward under power effect along oil pipe 22, when plunger 7 is by elastomeric sleeve 9, groove 8 is engaged the resistance to of the top of elastic plectrum 4
Mill projection 6, under effect of inertia, driving sliding sleeve 3 to move down and close stomata 5, elastomeric sleeve 9 isolates oil pipe 22 and sleeve pipe 23,
When sliding sleeve 3 reaches lower contact 1-1, stop movement, wear-resisting raised 6 jump out from groove 8, and plunger 7 leaves elastomeric sleeve 9, continue
Under fall on intermediate seat.As shown in Figure 4.
Step 4, wellbore pressure is recovered；After closing tubing valve 19, the water and natural gas on stratum, under strata pressure driving
Into pit shaft, borehole pressure progressively recovers, and stratum water gradually floods plunger 7 and elastomeric sleeve 9.As shown in Figure 5.
Step 5, plunger draining；When borehole pressure reaches ground control settings, ground control valve is opened, in oil pipe
Pressure is reduced rapidly, and pressure difference is formed in plunger face, using the pressure difference formed between oil pipe and sleeve pipe, liquid and plunger is upward
Lifting.When plunger 7 enters elastomeric sleeve 9, groove 8 is engaged wear-resisting raised the 6 of the top of elastic plectrum 4, under effect of inertia, band
Dynamic sliding sleeve 3, which moves up, opens stomata 5, the connection oil pipe 22 of elastomeric sleeve 9 and sleeve pipe 23, and the gas in sleeve pipe enters oil pipe, increases
The pressure of plunger base, plunger and liquid thereon accelerate and reach ground, when sliding sleeve 3 reaches top connection 1, stop moving
Dynamic, wear-resisting raised 6 jump out from groove 8, and plunger 7 leaves the water column on elastomeric sleeve 9 and top together, is acted in gas push
Under, continue to move to well head, as shown in Figure 6.The water of the bottom of plunger 7 falls on shaft bottom simultaneously, after plunger 7 reaches ground, in inertia
Plunger damper 14 is rushed under effect and is stopped wherein.
It is to be seen arrive ground not water outlet after, close tubing valve 19, repeat step 3 to 5, thus by switching oil pipe repeatedly
Valve 19, plunger 7 is allowed constantly to be moved up and down in device to realize gas well discharge opeing.
In summary, content of the present utility model is not limited in the above embodiments, in same area it is insighted it
Scholar can easily propose other embodiments within technological guidance's thought of the present utility model, but this embodiment is all wrapped
Include within the scope of the utility model.
