Connection.
Under second annexation, the concrete operating principle of well plunger is as follows：In the first annexation, voltage-controlled solution
After lock voltage-controlled elastic claw 102 beyond the Great Wall is mounted due to downward inertia with tight connecting seat 109, below voltage-controlled unblock plunger
Space can form sealing space.When gas is assembled in sealing space, the pressure in the sealing space of voltage-controlled unblock plunger lower section
Can be with the pressure initiation pressure difference above voltage-controlled unblock plunger.It is voltage-controlled when the upper and lower pressure difference of voltage-controlled unblock plunger is more than preset value
Voltage-controlled elastic claw 102 on unblock plunger can be separated with the pawl button 110 on tight connecting seat 109, so that voltage-controlled unblock plunger
Realize and separated with wire Launching and Bailing formula insertion seal operation cylinder.Now, drive a well equivalent to realizing underground.Wherein, preset value is
Be it is voltage-controlled unblock plunger unblock pressure difference, unblock pressure difference can according to demand by adjust voltage-controlled elastic claw 102 elasticity and tooth form
The angle at angle is controlled, and the present embodiment is not especially limited to this.
It is voltage-controlled to unlock the front lower of plunger after being separated with wire Launching and Bailing formula insertion seal operation cylinder due to voltage-controlled unblock plunger
Pressure in square sealing space can be converted into the motive force for promoting voltage-controlled unblock plunger to move up.Now, voltage-controlled unblock plunger
Can quickly move up.Wherein, when being moved up due to voltage-controlled unblock plunger, in the plunger barrel 101 in voltage-controlled unblock plunger
By-pass governing piston 105 is located in bypass flowing hole 104, that is, bypassing flowing hole 104 can be plugged.Now, plunger barrel is about 101
Not gas penetration.Therefore, voltage-controlled unblock plunger can ask the hydrops on top promptly to reach well head, so as to discharge product
Liquid.
When voltage-controlled unblock plunger reaches well head, because well head is provided with well head plunger catcher, caught by well head plunger
Catching the push rod at the top of device can push the by-pass governing piston 105 inside the plunger barrel 101 of voltage-controlled unblock plunger, make by-pass governing
Piston 105 is moved down along plunger barrel 101, so as to allow bypass flowing hole 104 to open.Can shape by upper and lower two bypass flowing holes 104
Into flow channels, there can be gas penetration about 101 so as to allow the plunger barrel of voltage-controlled unblock plunger.By said process, voltage-controlled solution
Lock plug successfully can again reach shaft bottom, and again with wire Launching and Bailing formula insertion seal operation cylinder mounting to discharge next time
Hydrops.
It should be noted that in above two annexation, well plunger can also include flow controller 111, upper slipses
112nd, cartridge 113 and lower slipses 114, specific annexation refer to Fig. 1, and the present embodiment is not especially limited to this.
In addition, the generalized section of well plunger can be as shown in Figure 2.
Well plunger provided in an embodiment of the present invention, inserts seal operation cylinder and hangs by voltage-controlled unblock plunger and wire Launching and Bailing formula
Connect, form sealing, so as to by Plunger Lift hydrops with before discharging hydrops, plunger lower section can accumulated gas forming foot
Enough big lifting forces, and then it is easy to follow-up discharge opeing.Therefore, the efficiency of hydrops discharge is higher.
