Description
Technical field
The utility model is related to a kind of oil well oil rig, in particular to a kind of hydraulic well pump.
Background technique
Due to being influenced by reservoir geologic character and structural property, during oil field development, substantial portion of oil pumping
Well capacity is gradually reduced, and hydrodynamic face decreases, and is in the insufficient situation of feed flow, in addition gases affect, this part well usually pump efficiency
Very low, development cost is high, and energy loss is serious.The design of hydraulic oil filling pump is exactly directed to this part pumpingh well, not using it
It can only make oil well pump from gases affect, improve pump efficiency, reduce energy consumption, and balance influence very little is adopted to the confession of oil well, it is existing
With the presence of hydraulic pump insufficient pressure, the insufficient technical problem such as patent low power consuming hydraulic well pump application number of low output
The hydraulic well pumps such as 2012102102180781 and patent hydraulic well pump number of patent application 032037252 are without pressurization dress
It sets.
New content
The utility model purpose provides a kind of hydraulic well pump for having supercharging device
The content of the present invention: the utility model is a kind of hydraulic well pump of the utility model realized by the following technical means,
Including pump plunger and barrel assembly, fixed valve, travelling valve, hydraulic system, oil sucting cavity, the oil sucting cavity bottom is provided with hydraulic booster dress
It sets, the supercharging device has hydraulic fluid entrance to be sequentially connected commutation valve group, reversing mechanism and hydraulic cylinder, is provided in hydraulic cylinder
Piston and hollow piston rod are provided below pressurization cylinder barrel in hydraulic cylinder, are pressurized in cylinder barrel and are provided with pressurization plunger, pressurization plunger
It connect pressurized cylinder bottom with hollow piston rod and is provided with well liquid channel, is connect with packer lower end well liquid area, well liquid on pressurized cylinder
Check-valves is provided in feeder connection and outlet.
It is preferred that commutation valve group is the inserting valve group of two-position four-way.
The utility model beneficial effect, increases supercharging device on oil well pump, provides pressurization using head of liquid in oil well pump
System improves the degree of filling of oil well pump, and of simple structure and strong practicability can industrialized production.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Pump plunger and barrel assembly 1；Commutate valve group 2；Casing 3；Hydraulic cylinder 4, hollow piston rod 5, travelling valve 6, fixed valve 7, on
Packer 8, check-valves 9, pressurization plunger 10, check-valves 11, pressurization cylinder barrel 12, reversing mechanism 13, hydraulic fluid entrance 14.
Specific embodiment
Kind hydraulic well pump described in the utility model, including pump plunger and barrel assembly 1, fixed valve 7, travelling valve 6, hydraulic system,
Oil sucting cavity, the oil sucting cavity bottom are provided with hydraulic pressure intensifier, and the supercharging device has hydraulic fluid entrance 14 to be sequentially connected to change
To 2 reversing mechanism 13 of valve group and hydraulic cylinder 4, it is provided with piston and hollow piston rod 5 in hydraulic cylinder 4, in 4 following settings of hydraulic cylinder
There is pressurization cylinder barrel 12, is pressurized in cylinder barrel 12 and is provided with pressurization plunger 10, pressurization plunger 10 is connect with hollow piston rod 5, pressurized cylinder
Bottom is provided with well liquid channel, and with packing, the connection of 8 lower end well liquid areas is pressurized on cylinder barrel 12 and sets in well liquid feeder connection and outlet
It is equipped with check-valves 11 and check-valves 9.
The utility model working principle hydraulic fluid flows through the inserting commutation valve group 2 of two-position four-way, into the lower chambers of hydraulic cylinder 4,
Piston, 5 pressurization plunger 10 of hollow piston rod uplink together are pushed, 4 upper chamber's liquid of hydraulic cylinder enters oil jacket by commutation valve group 2
The low-pressure area of annular space, while check-valves 9 closes the unlatching of check-valves 11 and is closed in pressurization 12 epicoele of cylinder barrel and hollow piston rod 5
Liquid enter oil sucting cavity be low-pressure state, when hollow piston rod 5 is up to vertex reversing mechanism 13 make commutate valve group 2 change
To hydraulic fluid enters the upper chamber into hydraulic cylinder 4, and pushing piston, 5 pressurization plunger 10 of hollow piston rod, downlink is stopped simultaneously together
It returns 9 opens check valve 11 of valve to close, pressurized liquid enters hydraulic well pump oil sucting cavity.
