Wherein, liquid can be obtained full of height with the stroke of piston from the corresponding indicator card of pumping unit in deep well pump.Deep well pump
Coefficient of fullness is related with oil reservoir fluid supply capacity, and when oil reservoir fluid supply capacity abundance, the piston in deep well pump enters pump when moving up
The liquid of chamber can be full of the space surrounded by pump chamber bottom surface, pump chamber side wall and piston, in this case, in deep well pump
The volume of liquid that piston enters the volume of the liquid of pump chamber when moving up and piston is conceded is equal, at this point, deep well pump is full of
Coefficient is 1；When oil reservoir fluid supply capacity deficiency, the liquid that the piston in deep well pump enters pump chamber when moving up will not be full of by pumping
The space that bottom of chamber face, pump chamber side wall and piston are surrounded, in this case, the piston in deep well pump enters pump chamber when moving up
The volume of liquid be less than the volume of liquid that piston is conceded, at this point, the coefficient of fullness of deep well pump is less than 1.
Step 202: according in the up stroke of sucker rod input motor maximum current, in the down stroke of sucker rod it is defeated
Enter the maximum current of motor and the property parameters of pumping unit, determines the single-unit operation power of pumping unit.

Coefficient of fullness, P1For load when suspension point does not unload in the down stroke of sucker rod.
It should be noted that above-mentioned formula (2) both can be adapted for the situation of oil reservoir fluid supply capacity abundance, at this point, deep-well
The coefficient of fullness of pump is 1, the situation of oil reservoir fluid supply capacity deficiency is readily applicable to, at this point, the coefficient of fullness of deep well pump is less than
1。
Certainly, in practical application, other sides can also be passed through according to the operating parameter of suspension point and the coefficient of fullness of deep well pump
Formula determines the suspension point operation power of pumping unit, and the embodiment of the present invention is not construed as limiting this.
Step 204: single-unit operation power being added with suspension point operation power, obtains power input to a machine.
It should be noted that the ground that power input to a machine is the electric energy drive pumping unit that external power supply inputs motor is set
The unit when size done work in the unit time when received shipment turns and the ground installation drive the moving components such as horse head and sucker rod mobile
The sum of the size done work in time, so in the outstanding of the single-unit operation power and pumping unit for determining pumping unit through the above steps
After point operation power, the single-unit operation power of pumping unit is added with the suspension point of pumping unit operation power, motor can be obtained
Input power.
Step 205: power input to a machine being multiplied with the electricity consumption time, obtains the electricity consumption of pumping unit.
It should be noted that meeting electricity consumption when motor works, so the electricity consumption time is the time of motor work.The electricity consumption time
It can be configured, and can be determined according to the needs of determination electricity used for oil extractor in advance, for example, when it needs to be determined that pumping unit
It when the electricity consumption to work half a day, can set the electricity consumption time to 12 hours, when it needs to be determined that the use that pumping unit works one day
When electricity, it can set the electricity consumption time to 24 hours, the embodiment of the present invention is not specifically limited in this embodiment.
Further, since pumping unit is in normal course of operation, the electricity consumption of pumping unit and the working system of pumping unit
Etc. factors it is related, in order to keep pumping unit more energy saving at work in the insufficient situation of oil reservoir fluid supply capacity, passing through step
After 205 determine the electricity consumption of pumping unit, the working system of pumping unit can be adjusted, to obtain energy-saving square accordingly
