Embodiment 1

[0026] A kind of pumping unit constant liquid surface oil recovery method of the present invention, realizes through following steps:

[0027] a. Determine the fluid level;

[0028] b. Collect the uplink and downlink active power of the motor;

[0029] c. Calculate the average uplink and downlink power;

[0030] d. Adjust stroke times: when the uplink power is greater than the average power of uplink and downlink, the dynamic liquid level will decrease and the stroke times will be reduced;

[0031] e. Constant liquid level oil recovery: adjust the stroke times of step d within the cycle time through the intelligent control device to achieve power balance and constant liquid level oil recovery.

Embodiment 2

[0033] A kind of pumping unit constant liquid surface oil production method of the present invention, realizes through following steps, as figure 1 Shown:

[0034] a. Determine the fluid level;

[0035] b. Collect the uplink and downlink active power of the motor;

[0036] c. Calculate the average uplink and downlink power;

[0037] d. Adjust stroke times: when the uplink power is greater than the average power of uplink and downlink, the dynamic liquid level will decrease and the stroke times will be reduced;

[0038] e. Constant liquid level oil recovery: adjust the stroke times of step d within the cycle time through the intelligent control device to achieve power balance and constant liquid level oil recovery.

[0039] The determination of the position of the dynamic fluid surface described in step a is realized by the following method: obtain the work W of the sucker rod weight 杆 , the work done by the weight of the oil column W 油 , the work done by the weight of the...
