Description
Technical field
The present invention relates to a kind of petroleum recovering device, specifically, relate to a kind of balance type two-way deep well oil pumping.
Background technique
At present, the main method of mechanical oil recovery can be divided into three kinds substantially both at home and abroad, the one, electric submersible pump, identical with submersible pump, be used for rich oil district and more shallow oil reservoir, then dual mode comprises beam-pumping unit and hydraulic piston pump, these two kinds of pumps have a common ground, promptly provide under the effect of power at ground installation, the interior piston of down-hole oil production pump is done to pump, the respective action of cooperation oil-feed valve and fuel-displaced valve is finished oil producing operation, Fig. 2 is the structural representation of beam-pumping unit, its main structure is that motor 1 provides power to make retarder 2 work, its objective is the reinforcing of slowing down, output shaft at retarder 2 is connected with rocking arm 3, by connecting rod 4 drive walking beams 5 horse head 6 being done pumps, horse head 6 connects sucker rod 7 through outstanding rope 21, described sucker rod 7 is in the inside of well casing 8 and 9 coaxial connections of piston of the oil extraction pump 10 of down-hole, described oil extraction pump 10 is provided with fuel-displaced valve 15 and oil-feed valve 16, described fuel-displaced valve 15 and oil-feed valve 16 are one-way valves, the filler opening of fuel-displaced valve 15 is communicated with pump chamber, oil outlet is communicated with well casing 8, the oil outlet of described oil-feed valve 16 is communicated with pump chamber, filler opening is communicated with pump oilbearing stratum outward, when piston 9 is up, oil-feed valve 16 is closed, fuel-displaced valve 15 is opened, under the pressure effect of piston, crude oil in the pump enters well casing 8 through fuel-displaced valve 15, send ground, and when piston 9 is descending, fuel-displaced valve 15 is closed, the oil-feed valve is opened, because the pull of vacuum that piston 9 forms when descending makes crude oil in oil-feed valve 16 suction pumps, back and forth finish once oil pumping circulation for such one, from here as can be seen, in traditional oil extraction pump, horse head is whenever done a to-and-fro motion can only finish an oil pumping circulation, and by observing our discovery, outstanding rope 21 between horse head 6 and the sucker rod 7 is soft, this just proves and need not power when piston 9 is done downward movement, and this moment, motor still consumed energy in work, and on rocking arm 3, add the action of gravity that iron overcomes sucker rod 7 of joining of suitable weight, there is serious imbalance in this explanation in traditional oil pumping unit, caused the waste of the energy.
And in traditional deep-well oil-extraction equipment, owing to be that oil extraction pump is directly placed oilbearing stratum, so will design the protective equipment of anti-silt on the pump housing when design, this just makes the oil recovery pump structure very complicated, has also increased the manufacture cost of oil extraction pump simultaneously greatly.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, manufacture cost is lower, can improve the balance type two-way deep well oil pumping that output again can energy saving.
For achieving the above object, technological scheme of the present invention is:
A kind of balance type two-way deep well oil pumping, comprise oil extraction pump, the top of described oil extraction pump is connected with well casing, be provided with the first fuel-displaced valve between described well casing and the oil extraction pump, be provided with piston in the described oil extraction pump, described piston is connected with the sucker rod that passes well casing is coaxial, described sucker rod is connected with ground pumping unit actuating unit, it is characterized in that: the external communications of described oil extraction pump has oil collecting pipe, be respectively equipped with the first oil-feed valve between described oil collecting pipe and the oil extraction pump, the second oil-feed valve, the described first oil-feed valve be positioned at oil extraction pump top and with the corresponding setting of the first fuel-displaced valve, described oil extraction pump bottom is provided with oil outlet tube, the oil outlet of described oil outlet tube is communicated with well casing, be provided with the second fuel-displaced valve between described oil outlet tube and the oil extraction pump, the described second fuel-displaced valve and the second oil-feed valve are separately positioned on the bottom and corresponding setting of oil extraction pump.
Below be that technique scheme of the present invention is further improved:
The below of described oil extraction pump is provided with airtight oil sump, the oil collect port of described oil collecting pipe is positioned at the bottom of oil sump, avoided the gas in the crude oil is entered in the oil collecting pipe, the casing wall of described oil sump is to be made of filter layer, crude oil enters into oil sump through filter layer, thereby guaranteed the pure relatively of crude oil, be that complicated geological environment is oversimplified in a sense, and oil extraction pump is a more simple suction source, so just recover the oil and created advantage for standardization, make the simple in structure of oil extraction pump, reduced the manufacture cost of oil extraction pump.
Beneficial effect
The present invention is simple in structure, reasonable use the gravity that deadweight produced of sucker rod, two circuit merits have been done with circuit time and energy, all be in meritorious state when making the sucker rod uplink and downlink, the complete equipment operation is more tended to balance, promptly in the unit time, improve output, saved the valuable energy again.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples
Fig. 1 is the structural representation of the embodiment of the invention;
Fig. 2 is the structural representation of embodiment of the invention background technique.
