The embodiment of the invention provides an intelligent control method of an oil pumping unit, and referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the intelligent control method of the oil pumping unit.
In this embodiment, the intelligent control method of the pumping unit includes the following steps:
step S10: and acquiring the real-time operation parameters of the target oil pumping unit, and screening the real-time operation parameters to obtain the periodic parameters.
It should be noted that, the execution main body of the method of this embodiment may be a computing service device with functions of data processing, data storage, network communication and program operation, for example, a digital pumping unit, an air pumping controller, a pumping system analyzer, or other electronic devices capable of implementing the same or similar functions and implementing the intelligent control method of the pumping unit, which is not limited in this embodiment. Here, an intelligent control device (hereinafter referred to as a control device) of the pumping unit is selected as an example to describe various embodiments of the intelligent control method of the pumping unit of the present invention.
It will be appreciated that the target pumping unit may be a digital pumping unit equipped with a remote terminal function capable of real-time data transmission communication with the control device. The operating parameters of the target pumping unit can be remotely transmitted to the control equipment through network signals so that the control equipment can monitor in real time, and can receive and execute control command instructions from the control equipment.
It should be noted that, the real-time operation parameters of the target pumping unit may include: parameters of the power line current, voltage, phase angle and the like of the motor of the target pumping unit, which can reflect the operation process of the pumping unit in real time, can be used for calculating and obtaining the active power and the reactive power of the pumping unit during working according to the parameters. Real-time operating parameters over a period of time may also be acquired to further determine the reliability of the acquired parameters.
It should be understood that, after acquiring the real-time operation parameters of the target pumping unit, in order to determine the validity of the acquired parameters to extract the periodic parameters that can more reflect the operating characteristics of the pumping unit, step S10 includes:
step S11: and acquiring the real-time operation parameters of the target oil pumping unit, and judging the fluctuation value of the real-time operation parameters in a first preset time period.
It is understood that the first preset time period may be a time range that is set before and after the time stamp based on the time axis sequence based on the acquisition time stamp of the real-time operation parameter. And acquiring fluctuation values of each parameter item in the real-time operation parameters in the first preset time period, and judging the stability of the parameter item so as to further judge the correlation between the parameter item and the operation process of the pumping unit.
Step S12: and screening out the real-time operation parameters with the fluctuation value larger than the preset fluctuation threshold value to obtain the periodic parameters.
It may be understood that the preset fluctuation threshold may be a preset value for specifically judging the correlation between the real-time operation parameter and the operation process of the pumping unit, where the preset fluctuation threshold may be a value that is set based on different parameter items in the real-time operation parameter, or may be a fluctuation threshold that is set in consideration of judging the overall fluctuation value of the real-time operation parameter including each parameter item.
The periodic parameter is a stable periodic parameter obtained by removing a parameter item with a low correlation with the operation process of the pumping unit, wherein the fluctuation value of the periodic parameter is larger than the threshold value.
In a specific implementation, after the control device obtains the real-time operation parameter of the target oil pumping unit, the real-time operation parameter can be stored in the temporary buffer area, and after judgment and screening, the real-time operation parameter is determined to be a stable periodic parameter, the periodic parameter is stored and the next matching process is performed. The accuracy of data recording and storage can be greatly improved, and the acquired parameter data are real-time and real data of the accuracy reflecting the operation working condition of the pumping unit.
Step S20: and matching the current working oil well of the target oil pumping unit according to the periodic parameters, and obtaining a historical parameter library corresponding to the current working oil well.
It should be noted that, a single pumping unit may work in a single oil well, and the periodic parameter may reflect the operation condition of the target pumping unit, so as to obtain the current working oil well of the corresponding target pumping unit according to the operation condition.
It should be understood that the historical parameter library may be historical working data of the pumping unit running in the working oil well, where the working data may include the running time and total pumping quantity of the pumping unit, and may also include its own parameters of the working oil well, such as the level of the well fluid of the working oil well, the change trend, the well fullness, etc. Different working wells may have respective corresponding historical parameter libraries.
It can be appreciated that the history parameter library may be stored in a local memory of the control device, or may be stored in a cloud server, and the history parameter library is acquired based on network communication when the control device needs to make a call, which is not limited in this embodiment.
In a specific implementation, when the control device obtains the periodic parameter reflecting the operation working condition of the target oil pumping unit, the control device can determine the current working oil well of the target oil pumping unit based on the unique corresponding relation between the target oil pumping unit and the working oil well, and obtain a historical parameter library corresponding to the current working oil well.
Step S30: and generating the idle pumping condition of the current working oil well according to the historical parameter library.
It should be noted that, the idle pumping condition of the current working oil well may be the idle pumping submergence of the pumping unit in the working oil well generated according to the historical parameter library. The empty pumping sinking degree can be determined by the liquid yield of the current working oil well, the stroke frequency, the stroke and the suspension point height of the operated pumping unit, which are obtained from a historical parameter library.
Step S40: and when the periodic parameter accords with the idle pumping condition of the current working oil well, judging that the target oil pumping unit is in an idle pumping state, and controlling the target oil pumping unit in the idle pumping state to stop running.
It will be appreciated that the operational parameters of the target pumping unit may be determined from the periodic parameters, and may include characteristic parameters of the pumping unit that specifically reflect the pumping unit operating conditions, such as stroke frequency, stroke, and unit oil extraction. And comparing the characteristic parameters of the working condition of the reaction pumping unit with the determined idle pumping condition, and judging that the target pumping unit is in an idle pumping state when the parameters are in a data range limited by the idle pumping condition.
In a specific implementation, the control device compares the periodic parameter of the target pumping unit with the idle pumping condition generated by the historical parameter library, and when the periodic parameter is within the data value range defined by the idle pumping condition, the control device can judge that the target pumping unit which is running in the current working oil well is in an idle pumping state, and further control the target pumping unit to stop running based on wireless communication so as to reduce energy consumption.
Firstly, acquiring real-time operation parameters of a target oil pumping unit, and screening the real-time operation parameters to obtain periodic parameters; then matching the current working oil well of the target oil pumping unit according to the periodic parameters to obtain a historical parameter library corresponding to the current working oil well; generating the idle pumping condition of the current working oil well according to the historical parameter library; and finally, when the periodic parameter accords with the idle pumping condition of the current working oil well, judging that the target oil pumping unit is in an idle pumping state, and controlling the target oil pumping unit in the idle pumping state to stop running. According to the embodiment, the periodic parameters obtained by screening the real-time operation parameter fluctuation value are matched to obtain the history parameter library corresponding to the current working oil well, the idle pumping condition is generated based on the history parameter library, the idle pumping judgment is carried out on the pumping unit to control the pumping unit in the idle pumping state to stop operation, the real-time parameters of the pumping unit and the history parameters of the working oil well operated by the pumping unit can be combined to generate the idle pumping condition with higher reliability, the judgment accuracy of the idle pumping state of the pumping unit is improved, the pumping unit meeting the condition can be timely controlled to stop operation, and the energy conservation and consumption reduction of the pumping unit are realized.
Referring to fig. 3, fig. 3 is a schematic flow chart of a second embodiment of the intelligent control method of the pumping unit of the present invention.
Based on the above embodiment, considering that different oil wells have differences between oil field types and oil field development degrees, there may be a one-to-one mapping relationship between parameter settings of different pumping units and working oil wells operated by the different pumping units, step S20 includes:
step S21: and acquiring a working oil well corresponding to the periodic parameter from a working oil well preset parameter table, and determining the working oil well as the current working oil well of the target oil pumping unit.
It should be noted that, the preset parameter table of the working oil well may be a preset parameter table including the corresponding relations between the periodic parameters of different pumping units and the working oil well. Therefore, after the periodic parameters reflecting the working condition of the target pumping unit are determined, the working oil well corresponding to the target pumping unit can be obtained by inquiring the preset parameter table.
Step S22: and when the current working oil well is determined, acquiring a historical database of the current working oil well corresponding to the target oil pumping unit.
It can be understood that the historical database of the working oil well can comprise the level height and the liquid yield of the well liquid of the working oil well, and the working oil well which is normally produced has relatively stable working fluid level and liquid yield, so that the degree of development of the working oil well can be updated according to the data of the pumping unit which is operated in the working oil well and the data of the working oil well, and the degree of fullness of the current working oil well can be determined.
Further, since the well fluid of the working well is a relatively stable working fluid level, the real-time fluid level of the current working well can be used as a determined value, and the idle pumping condition of the current working well can be determined by combining the working condition of the target pumping unit, and the step S30 includes:
step S31: and acquiring the first well fluid level of the current working well based on the historical parameter library.
The first well fluid level may be a working fluid level of the target pumping unit when the current working well starts to operate. The first well fluid level may reflect the field development of the current working well.
Step S32: and obtaining the unit oil extraction amount of the target oil pumping unit according to the periodic parameters.
In the concrete implementation, the stroke frequency, stroke, suspension point and the like of the target pumping unit can be determined according to the periodical parameters and used for reflecting the operation numerical value of the pumping unit pump displacement, and the unit oil extraction amount of the target pumping unit can be determined by combining the accumulated oil extraction time.
Step S33: and combining the unit pumping quantity of the target pumping unit with the first well liquid level to generate the idle pumping condition of the current working oil well.
In specific implementation, the control device can generate the idle pumping condition of the current working oil well according to the unit oil pumping amount of the target oil pumping unit and the running time of the target oil pumping unit and by combining the first well liquid height of the current working oil well and the dynamic liquid level change trend in the running time of the target oil pumping unit, and acquire the idle pumping judgment standard aiming at the actual development condition of the current working oil well.
Further, after the step S33, when the periodic parameter is compared with the empty pumping condition, the unit pumping amount determined by taking into consideration the acquired parameter of the target pumping unit and the well fluid water of the current working wellThe level is in fact an approximation over a period of time, so that probability condition satisfaction principles can be introduced. In particular, a probability factor T can be set, when the periodicity parameterWhen (satisfying the empty drawing condition), there is +.>The method comprises the steps of carrying out a first treatment on the surface of the When periodicity parameter->0 (no air-pumping condition is satisfied), there is +.>. Until the probability factor reaches a threshold number, e.g., 100, for a period of time, at which point the target pumping unit is determined to be in a null pumping state.
Further, considering that the operation parameters of the target pumping unit are easily affected by external factors such as environmental factors, the actually obtained operation parameters have a certain difference from the parameter values used for matching the corresponding working oil well, so that the periodic parameters obtained by screening the real-time operation parameters can be updated, and before step S21, the method comprises the following steps:
step S021: and when the working oil well corresponding to the periodic parameter cannot be acquired in the working oil well preset parameter table, acquiring the weather characteristic factor of the area where the target pumping unit is located.
Step S022: and updating the periodic parameters according to the weather characteristic factors.
Accordingly, the step S21 includes:
step S21': and acquiring a working oil well corresponding to the updated periodic parameter from a working oil well preset parameter table, and determining the working oil well as the current working oil well of the target oil pumping unit.
The working oil well corresponding to the periodic parameter is obtained from a working oil well preset parameter table, and the working oil well is determined to be the current working oil well of the target oil pumping unit; and when the current working oil well is determined, acquiring a historical database of the current working oil well corresponding to the target oil pumping unit. Then, acquiring the first well fluid level of the current working well based on the historical parameter library; obtaining the unit oil extraction amount of the target oil pumping unit according to the periodic parameters; and combining the unit pumping quantity of the target pumping unit with the first well liquid level to generate the idle pumping condition of the current working oil well. Because the embodiment considers the differences of oil field types and development degrees of different working oil wells and dynamically combines the working condition parameters of the target pumping unit, the idle pumping condition more suitable for the target pumping unit and the current working oil field can be generated, and the accuracy of the control equipment in judging the idle pumping condition of the pumping unit is further improved.
Referring to fig. 4, fig. 4 is a schematic flow chart of a third embodiment of the intelligent control method of the pumping unit of the present invention.
Based on the above embodiment, considering the normally produced oil well, after the pumping unit stops working, the production layer still continues to be discharged for a period of time, so that the liquid level of the oil well is restored. Thus, the target pumping unit which is stopped can be controlled to work, and after step S40, the method includes:
step S41: and acquiring a liquid level model of the current working oil well, and setting a standard liquid level.
It should be noted that the fluid level model of the working well may be a fluid level restoration curve of the current working well determined based on a historical database and/or an existing fluid level restoration model of the well in the network.
The standard liquid level height may be a preset height value for determining that the target pumping unit can normally operate under the well liquid level height without an empty pumping state. Different standard liquid levels can be set for liquid level models of different types of working oil wells respectively, and a unified standard liquid level can also be set, which is not limited in this embodiment.
Step S42: and inputting the first well liquid level and the standard liquid level into the liquid level model to obtain a second preset time period.
It should be understood that, because of the differences in physical properties, pressure, flooding conditions and the like of different working oil wells, the continuous liquid outlet conditions of the working oil wells after the pumping unit is stopped are also greatly different, so that the liquid level recovery curves are different. To facilitate rapid matching to the fluid level model that is appropriate for the current working well, the fluid level model of the working well can be broadly divided into three categories.
Referring to fig. 5, fig. 5 is a schematic diagram of three types of fluid level models of working wells, i.e., well fluid level recovery curve types. In fig. 5, there are three types of fluid level models of working wells: very poor (I), general (II) and excellent (III), where H0 is the first well fluid level and H is the set uniform standard fluid level. T is the time when the control device controls the target pumping unit to stop running in the idle pumping state, and T (T (III) and T (II)) is the time when the control device controls the target pumping unit to start running after a second preset time period.
In a specific implementation, when the first well fluid level is obtained, substituting the first well fluid level into the determined fluid level restoration curve, so that the interval time of restoring the fluid level of the current working oil well to the standard fluid level, namely the second preset time period, can be obtained, and further, the time that the target pumping unit can start to operate is determined based on the time of stopping the target pumping unit.
Step S43: and acquiring the second well liquid level height of the current working oil well after the second preset time period is spaced, and controlling the target oil pumping unit to operate when the second well liquid level height is larger than the standard liquid level height.
It can be understood that after the second preset time period passes, the second well liquid level height of the current working oil well, that is, the actual liquid level recovery height of the current working oil well after the second preset time period passes, can be obtained, so as to further judge whether the target oil pumping unit can normally operate under the well liquid level height without empty pumping.
In a specific implementation, when the control device determines a second preset time period according to the liquid level recovery curve, the control device obtains the second well liquid level of the current working oil well, compares the second well liquid level with the standard liquid level to determine that the well liquid level of the current working oil well at the moment does not accord with the idle pumping condition of the current working oil well, so that the control device controls the target pumping unit to start and operate at the moment, flexible control of the pumping unit can be realized, and the working efficiency of the pumping unit is improved.
Further, after step S40, the method further includes:
step S401: and when the target oil pumping unit is judged to be in the idle pumping state, comparing the periodic parameter with the warning parameter.
Step S402: based on the comparison result, when the periodic parameter accords with the warning parameter, generating an early warning prompt of the target pumping unit so as to enable a user to further judge.
It can be understood that the alarm values can be set for each parameter item in the periodic parameters respectively, and when the parameter item accords with the alarm value, the target pumping unit can be considered to have suspicious abnormal working conditions, so that the prompt and early warning of the target pumping unit can be generated to facilitate the user to further judge the working conditions of the target pumping unit.
According to the embodiment, the liquid level height model of the current working oil well is obtained, and the standard liquid level height is set; inputting the first well liquid level and the standard liquid level into the liquid level model to obtain a second preset time period; and acquiring the second well liquid level of the current working oil well after the second preset time period is spaced, controlling the target oil pumping unit to operate when the second well liquid level is greater than the standard liquid level, flexibly controlling the target oil pumping unit, improving the working efficiency of the target oil pumping unit, setting warning parameters, and generating early warning prompts when the periodic parameters of the target oil pumping unit have larger errors so as to enable a user to further confirm the working condition of the target oil pumping unit.
In addition, the embodiment of the invention also provides a storage medium, wherein the storage medium is stored with an intelligent control program of the oil pumping unit, and the intelligent control program of the oil pumping unit realizes the steps of the intelligent control method of the oil pumping unit when being executed by a processor.
