Interface K44 is connected by connecting branch pipe with lift tube 47 respectively；Drainage interface W45 is connected by connecting branch pipe with drainage tube 48.
The exhaust outlet of the booster pump blast pipe 37 is higher than the liquid level that drainage tube 48 is determined.The effect of power piston is to utilize pressure
Difference produces reciprocating motion, is that drainage piston 13 and lifting piston 14 provide power；The effect of drainage piston 13 is suction packer 2
Simultaneously pump bottom is gone back in drainage to the hydrops that upper annulus occurs, to ensure that the upper annulus of packer 2 is in the low pressure shape without fluid column all the time
State；The effect of lifting piston 14 is suction and mining formation fluid to ground.
Packer 2 is set in internal surface of sleeve pipe, thus well bore isolation into space independent up and down.Upper space connected well
Mouthful, form two low pressure runners with oil pipe annular space in oil pipe.Lower space connected well bottom, from top to bottom full of from reservoir
Pressed gas and liquid.Constant pressure valve 6 is installed, for controlling gas pressure not higher than arranges value on packer 2.Work as hypertonia
When, constant pressure valve 6 is opened, and a part of gas is directly entered the oil jacket annular space on top, freely rises to well head.
During the supercharging pump work, set be suspended on internal surface of sleeve pipe first, then the pressed gas and liquid of reservoir respectively from
Air inlet 7, the filter 5 of pump are continuously flowed into, and reversal valve 8 and piston component 4 is worked automatically, so that stratum liquid in a steady stream not
Well head is lifted to disconnectedly.When reservoir gas and liquid separately flow into power piston chamber and lifting plunger shaft, due to power piston
Diameter is more than lifting piston, and the thrust that gas acts on power piston side as high-voltage power supply exceedes the resistance at lifting piston
Power, piston component 4 is promoted to move together, while the liquid compressed in lifting plunger shaft is pressurized to it, and open check valve, will
It is lifted in oil pipe, and completion is once lifted.By the automatic reverse of reversal valve 8, reservoir gas is used as high-voltage power supply alternating action
In power piston both sides, and promote piston component 4 to move back and forth, realize the continuous work of booster pump.
The motion process of reversal valve and piston component is：The high-voltage power supply of gas access 22 is through the core runner of reversal valve 8 and drainage
Interface C25 is connected, and drainage interface C25 enters power piston A10 upper ends by communicating pipe B41 again.Now, drawing on reversal valve 8
Stream interface B24 low-pressure ends are connected with drainage interface D26, and drainage interface D26 enters the end cap E19 of power piston through communicating pipe C,
Because power piston is in top high pressure, bottom low-pressure state, therefore operation downwards, and the drainage piston for driving its underpart to connect
13 are moved down with lifting piston 14, and the liquid of the lower chamber of drainage piston 13 is led back into pump bottom, while will the lower section of lifting piston 14
The liquid of chamber is lifted in the top oil pipe 1 of packer 2, the chamber feed liquor of the top of lifting piston 14.During this, work as power
When piston A10 piston runs to lower extreme point position, when striking the lance 34 on end cap B16, end cap check valve B33 is opened,
Connect drainage interface H32 and drainage interface N36 so that drainage interface N36 high pressures are released to low-pressure state, now, reversal valve 8
The drainage interface A23 of upper end is that low pressure, gas access 22 are still high pressure, and the valve element of reversal valve 8 is moved up, so that gas access 22
Connected with drainage interface D26 and turn into high pressure source.Because drainage interface D26 is connected with the end cap E19 of power piston, power
Piston C12 lower surface is converted into high pressure, and the drainage interface O39 of its upper surface is now connected with drainage interface B24 and turned into low
Pressure side, under upper low, lower high pressure effect, power piston is converted to up, and the He of drainage piston 13 for driving its underpart to connect
Lifting piston 14 is moved up, and thus the hydrops of the top annular space of packer 2 is returned to the lower section of drainage piston 13 by the drainage of drainage tube 48
Chamber, while the liquid for lifting the upper chambers of piston 14 is lifted in the top oil pipe 1 of packer 2 by lift tube 47.When dynamic
When power piston A10 piston runs to upper extreme point position, the lance 30 on end cap A15 is hit, end cap check valve A29 is opened, even
Logical gas access 22 and drainage interface A28 so that drainage interface A28 is in high pressure conditions, the drainage interface of the upper end of reversal valve 8
A23 is also high pressure.Because the valve element upper surface of reversal valve 8 is more than lower surface, the high-voltage power supply of gas access 22 is to the valve element of reversal valve 8
Downwards, valve element is descending, so that gas access 22 connects with drainage interface A25 and turns into high pressure source for active force.So far, commutate
Valve 8 and piston component 4 have been returned to original state, and repeat said process.
The booster pump makes full use of reservoir gas energy reversal valve 8 and piston component 4 is worked automatically, and its energy is changed
To down-hole liquid, fluid pressure greatly improved, the effect of " blowing " is reached, so as to effectively solve existing artificial lift cost
It is high, the problem of energy consumption is big, realize that oil gas is stable, the purpose of high-efficiency mining, and be particularly suitable for use in gas stringer, gassiness oil well and coal
The downhole pressure increasing operation of different well depths in layer gas well.
