Brief description of the drawings
Fig. 1 is the safe handling status architecture schematic diagram of the present invention.
Fig. 2 is Fig. 1 right view.
Fig. 3 is Fig. 1 close-up schematic view.
Embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
Embodiment one.
As Figure 1-3.
A kind of hydraulic drive type oil extraction system, it includes：
One fluid power system 42, the fluid power system are arranged on ground 79, are to adopt under control system control
Oil provides work power oil；As shown in Figure 1, 2, can be realized using prior art；
One piston cylinder 81, the piston cylinder 81 are arranged in sleeve 93, and sleeve pipe 93 is arranged in oil recovery well casing 94；Piston cylinder
81 are connected with least two power oil pipes 91, two power oil pipe alternations, wherein a power oil pipe 91 is used to drive work
Plug 84 move up and piston cylinder on the oil suction from flow string of oil inlet 83, another power oil pipe be used to drive piston 84
Move down and carry out oil suction preparation；
One piston 84, it is arranged in piston cylinder 81 and realizes circumferential seal by piston ring and piston cylinder；Piston 84 is in
I-shape construction, in order to improve stability, it is embodied into can also install a guide way 95 additional in piston cylinder 81, such as Fig. 3 institutes
Show, motion realizes that the power oil of oil suction enters the centre of I-shaped piston, the downward power of driving piston to driving piston 84 upwards
Oil enters in the piston cylinder 81 on the top of piston 84, and the crude oil in oil well enters piston under suction function from the bottom of piston cylinder 81
Discharged in cylinder and from the fuel sucking pipe 87 being connected with piston cylinder bottom outside piston cylinder.
One fuel sucking pipe 87, the entrance point of the fuel sucking pipe are connected with the oil inlet 83 of the lower end of piston cylinder 81, its oil-out
It is connected with flowline 85；Flowline 85 is arranged on the upper end of piston cylinder 81, is provided with and is used on the entrance point of flowline 85
The check valve 88 of gathered oil backflow is prevented, the port of export of flowline 85 is connected with oil field oil storage tank 92.
Embodiment two.
The difference of the present embodiment and embodiment is that piston cylinder 81 is two-way cylinder, the oil-feed during piston is downward upwards
Mouth 83 can realize that oil producing operation is realized in vacuum suction.
The present invention operation principle be：
First, the piston cylinder 81 of the present invention is fitted into sleeve pipe 93, and oil extraction operation face is together dropped to sleeve pipe 93；Open
Hydrodynamic pressure drive system 42, the work of fluid power system 42 produce the hydraulic oil needed for work, and hydraulic oil passes through one（It is or more
Root）Power oil pipe 91, which is sent into the cavity on the top of piston cylinder 91, makes piston 84 decline in place, and then switching power oil enters another
Root（Or more）Piston 84 is forced to move upwards in power oil pipe 91, in the bottom of piston cylinder 84 generation negative pressure, producing well
Crude oil enters in piston cylinder under suction function from the oil inlet 83 of the bottom of piston cylinder 84, and with the increasing of negative pressure, crude oil is in a steady stream
Constantly flowing into flowline 85 from the fuel sucking pipe 87 being connected with the bottom of piston cylinder 84, then be sent into by petroleum pipeline in oil field
Pre-processed in conventional oil storage tank.When piston stroking upward in place after, when descending again, the crude oil in flowline 85 is in check valve
It will not be flowed back in the presence of 88, descent of piston starts another oil recovery process afterwards in place, so circulation, and crude oil is constantly from oil well
Middle suction out is sent into oil storage tank.If make piston cylinder into double acting cylinder, you can realize continual crude oil collection.
Part that the present invention does not relate to is same as the prior art or can be realized using prior art.
