The driving motor 101 is connected to the decelerator 102, and is used for driving the decelerator 102 to rotate, so as to drive the crank 104 connected to the decelerator 102 to perform a rotational motion, and further drive the walking beam 106 connected to the crank 104 through a connecting rod, the horse head 108 mounted on the walking beam 106, and the oil well pump 200 connected to the horse head 108 through a traction rope to perform a reciprocating motion.

The walking beam support 106 is fixedly connected to the ground.
One end of the walking beam 106 is connected with the crank 104 through a connecting rod, and is connected with the walking beam bracket 106 at a position close to the middle of the walking beam 106, so that the walking beam can reciprocate along with the circular motion of the crank 104 by taking the connecting point of the walking beam 106 and the walking beam bracket 106 as a fulcrum.

In this embodiment, the pump efficiency input screen includes a start button and a stop button. The worker determines the inputted pump efficiency by pressing the start button after inputting the desired predetermined pump efficiency.
In the present embodiment, when the worker presses the start button, the frequency conversion unit 209 gradually increases the frequency of the current flowing through the drive motor 101 from zero to the same frequency as the initial frequency according to the initial frequency set in advance. After the pumping unit finishes pumping with one stroke, the frequency of the current flowing through the driving motor 101 is adjusted according to the generated current indicator diagram.

the torque T obtained by calculation is the load on the ordinate in the indicator diagram.
In other embodiments, because the factors affecting the load also include the parameters of the driving motor 101 and the efficiency of the oil pumping transmission mechanism, the influence of the fixed electrical parameters and the transmission parameters also needs to be considered in the process of calculating the load, and the calculation process is more complicated.
In this embodiment, when the driving motor 101 drives the reducer 102 and the crank 104 connected to the reducer 102 to rotate, any position where the crank rotates corresponds to any position where the horse head 108 connected to the walking beam pulls the oil well pump to reciprocate one by one.

And setting the stroke of the oil well pump at the lowest point to be 0, and calculating to obtain the stroke of the oil pumping unit 10 corresponding to the load in the current state. And finally, generating a current indicator diagram according to the obtained load and stroke.
Once the current indicator diagram is acquired, the control cabinet control unit 215 controls the control cabinet communication unit 214 to transmit the acquired current indicator diagram and the corresponding pump unit number to the management server as indicator diagram information.
The comparison determination unit 208 compares the current indicator diagram with the reference indicator diagram to determine whether there is a deviation, and if so, the adjustment frequency generation unit 210 generates the adjustment frequency from the deviation.
The frequency converter 209 converts the frequency of the current of the driving motor 101 according to the adjustment frequency, thereby changing the frequency of strokes of the pumping unit 10 and further changing the pumping efficiency of the pumping unit 10.
The failure indicator diagram storage unit 211 stores a plurality of failure indicator diagrams corresponding to failure of the pumping unit during pumping and a plurality of corresponding failure names. The fault indicator diagram comprises a plurality of corresponding serious fault indicator diagrams when serious faults occur in the oil pumping process and a plurality of corresponding slight fault indicator diagrams when slight faults occur in the oil pumping process.

The workman can set up required pump efficiency according to the production plan in oil field, and the oil mass that produces when the plan increases, thereby the workman controls the pump efficiency of this beam-pumping unit through setting up higher pump efficiency in oil well department, improves the oil production volume of this beam-pumping unit. The method greatly improves the management efficiency of oil field production and is convenient for the oil field to realize large-scale automatic production.
The intelligent management system for the pump efficiency adjustment oil field provided by the embodiment is characterized in that the pumping unit control cabinets are arranged at the pumping units, the current indicator diagram is obtained by calculating the electrical parameters of the driving motor of the pumping unit and the parameters of the pumping unit in real time according to the measurement of the pumping unit control cabinets, and the obtained current indicator diagram is displayed at the administrator terminal. The indicator diagram is an important tool for helping an administrator to know the working state of the pumping unit, and the embodiment enables the administrator to obtain the working state condition of each pumping unit in an oil field in real time on a held administrator terminal. Therefore, managers can reasonably arrange production plans in time according to the working conditions of all the pumping units. The problem of low efficiency caused by information lag is avoided. Meanwhile, the current indicator diagram is displayed on the oil pumping control cabinet, so that workers in an oil field can obtain the operation condition of the oil pumping unit beside the corresponding oil pumping unit, the workers can conveniently master the state of the oil pumping unit without inquiring an administrator, and the oil pumping unit can be overhauled in time when necessary.
In the intelligent management system for pump efficiency adjustment oil field provided by this embodiment, the administrator can obtain the current indicator diagram and stroke frequency of the pumping unit corresponding to the number, the fault of the pumping unit, the time of the fault, the position of the pumping unit and the model of the pumping unit by selecting the number of the pumping unit. When a certain pumping unit in the oil field breaks down, the manager can timely know the position and the fault type of the broken pumping unit and timely contact the maintenance personnel to the position of the pumping unit to maintain the pumping unit. Compared with the prior art that the state of the pumping unit needs to be detected and acquired, the response time when the fault occurs is saved, so that the pumping unit with the fault can be put into production continuously as soon as possible.
The intelligent management system for the pump efficiency adjustment oil field provided by the embodiment compares the current indicator diagram with the serious fault indicator diagram through the comparison judgment part to judge whether the current indicator diagram and the serious fault indicator diagram are the same or not, further, when the judgment is yes, a red alarm lamp of the alarm part is turned on, the fault is stored in the management server, and meanwhile, the frequency of the current of the driving motor is adjusted to be zero so as to control the pumping unit to stop pumping oil. Therefore, when serious faults occur in the production process, the production can be stopped in time, and the greater economic loss is avoided. Meanwhile, the worker is prompted to stop due to serious faults of the pumping unit through an obvious red alarm lamp, and the pumping unit needs to be maintained as soon as possible.

Due to the reduction of the stroke frequency, the loss caused by continuous production of the oil pumping unit without stopping under slight fault is reduced. Because the time required for stopping the machine for maintenance is long, generally two to three days are required, the pumping action device is not controlled to stop working when a slight fault occurs, so that the larger economic loss can be avoided. And through the display of the operating terminal on the fault name, workers can intuitively know the fault content of the oil pumping unit, and regular maintenance and inspection can be conveniently arranged.
Compared with the traditional method for obtaining the indicator diagram by using a load sensor and a displacement sensor, the pump efficiency adjustment oilfield intelligent management system provided by the embodiment has the advantages that the influence of temperature and time interval environment on the measuring process is small, and the accuracy of the current indicator diagram obtained by calculation is improved.
