However, in production practice, each oil production worker needs to manage a plurality of wells, the night interval is long, if a faulty well cannot be known and treated in time, and especially in the northeast area, if the faulty well is not treated in time, serious accidents such as well freezing and pipeline freezing are easily caused. In view of the above, the embodiment of the invention provides a method for monitoring the operation time rate of an oil pumping unit, which aims to solve the technical problems.
Referring to fig. 1, fig. 1 is a flow chart of a method for monitoring the operation time rate of an oil pumping unit according to an embodiment of the present invention, where the method includes:
s101, data acquisition: and acquiring the operation and stop time of the pumping unit, wherein the stop of the pumping unit comprises normal stop and abnormal stop, and the normal stop comprises swinging stop.
S102, acquiring a runtime rate: and obtaining the operation time rate of the pumping unit according to the time interval of the operation and the stop of the pumping unit.
S103, monitoring: includes a step of S1031 learning and a step of S1032 alarming.
Learning: acquiring the previous swing time under the swing stop state, acquiring the current swing time under the swing stop state, comparing the previous swing time with the current swing time, and alarming when the current swing time is different from the previous swing time; when the preset number of times of alarm is given, the swing time is unchanged all the time, and the swing time which is unchanged is counted and the alarm is not given any more.
Alarming: and alarming when the pumping unit is in an abnormal stop state.
The method provided by the embodiment of the invention has at least the following beneficial effects:
According to the method provided by the embodiment of the invention, the running time rate of the pumping unit is obtained through the accumulated calculation of the time, whether the pumping unit works normally or not can be monitored through the running time rate, and as the stopping of the pumping unit comprises normal stopping and abnormal stopping, the normal stopping comprises swinging stopping, the swinging stopping is the control mode of a pointer to the pumping unit, namely, the pumping unit stops working, but a balancing weight connected with a pumping rod continuously swings, the previous swinging time in the swinging stopping state is obtained through the learning step in the monitoring step, the current swinging time in the swinging stopping state is obtained, and the alarm is given when the current swinging time is different from the previous swinging time; when the preset times of alarming are carried out, the swing time is unchanged all the time, the swing time which is unchanged is counted, and the alarm is not carried out any more; alarming when the pumping unit is in an abnormal stop state; the method provided by the embodiment of the invention also monitors the operation time rate of the pumping unit when the swing type stops, and even if the pumping unit fails in the mode, the pumping unit can be monitored so as to avoid loss and improve the oil extraction efficiency.
The method provided by the embodiments of the present invention will be further explained and described below by alternative embodiments.
S101, data acquisition: and acquiring the operation and stop time of the pumping unit, wherein the stop of the pumping unit comprises normal stop and abnormal stop, and the normal stop comprises swinging stop.
The pumping unit is in a stop state and is in an abnormal stop state at the moment when the belt is broken, power failure or the sucker rod is broken and the like in the operation process. Normal stop means that the pumping unit is not operating, but the above-mentioned failure does not occur. The swing type stopping means that the pumping unit is controlled to swing, namely, the pumping unit stops, but the balancing weight connected with the pumping unit swings in an arc shape at a certain frequency, and at the moment, the data acquisition device can acquire the swing time of the pumping unit, but does not perform fault alarm.
S102, acquiring a runtime rate: and obtaining the operation time rate of the pumping unit according to the time interval of the operation and the stop of the pumping unit.
The running time and the stopping time of the pumping unit are acquired in real time through a data acquisition device arranged on the beam of the pumping unit, the time is transmitted to a processor in a control cabinet, the running time and the stopping time of the pumping unit are accumulated, and the running time rate of the pumping unit can be obtained through the time difference. As an example, when the pumping unit is in operation, the data collector sends the time of the pumping unit operation to the processor for storage, and when the pumping unit is stopped, the data collector sends the time of the stopping to the processor for storage, namely, the pumping unit is driven, the static sends a time sequence, and then the static sends a time sequence, so that the time sequences of the driven, the static and the static are repeatedly sent to the processor in the control cabinet for storage, and the operation time rate of the pumping unit is calculated by the processor.
S103, monitoring: includes a step of S1031 learning and a step of S1032 alarming.
S1031, learning step: acquiring the previous swing time under the swing stop state, acquiring the current swing time under the swing stop state, and alarming when the current swing time is different from the previous swing time; when the preset number of times of alarm is given, the swing time is unchanged all the time, and the swing time which is unchanged is counted and the alarm is not given any more.
It will be appreciated that for a rocking stop, the data sensor will also collect the time it is rocking, but will not alarm, only when a fault occurs in the rocking stop mode, but will be difficult to alarm for a fault because it is difficult to determine the status of the fault in the rocking stop.
According to the embodiment of the invention, through setting a learning step, the previous swinging time in the swinging stop state is obtained through a data sensor, namely the swinging time of the balancing weight of the pumping unit is continuously kept before the current time, as an example, before the swinging time of the balancing weight is counted, the swinging time of the balancing weight is counted again, the swinging time of the balancing weight is 3 hours, and is different from the swinging time of the previous time, so that the pumping unit is indicated to be faulty, or the swinging time is changed, the pumping unit can alarm according to the difference between the swinging time of the current time and the swinging time of the previous time, when the preset times are alarmed, and the pumping unit can alarm for 2-4 times and then find that the swinging time of the current time is always kept unchanged, so that the pumping unit is not faulty, and the swinging time of the current time is used as a comparison standard after the swinging time of the next time is changed. Therefore, the operation time rate of the pumping unit in the swinging type stop state can be monitored through the self-learning of the system, the normal operation of the pumping unit is ensured, and the oil extraction efficiency is improved.
It should be noted that, the preset number of alarm times may be set according to the need, which is not limited in the embodiment of the present invention.
In an alternative embodiment, the learning step further includes obtaining a first swing frequency in a previous swing time in the swing stop state, and obtaining a second swing frequency in a current swing time in the swing stop state;
comparing the first swing frequency with the second swing frequency to obtain a comparison result;
and alarming according to the comparison result.
In an alternative embodiment, alerting is based on the comparison, including alerting when the second wobble frequency is less than the first wobble frequency.
It will be appreciated that in the swing type stop state, the swing frequency may be changed due to other reasons, for example, the screw loosening occurs at the connection position on the pumping unit or the connection position is blocked by a foreign matter, and the balancing weight can swing as usual, but the frequency is changed due to the influence of the foreign matter or the screw loosening. Therefore, the embodiment of the invention obtains the second swing frequency in the current swing time in the swing stop state by obtaining the first swing frequency in the previous swing time in the swing stop state; comparing the first swing frequency with the second swing frequency, if the first swing frequency is different from the second swing frequency, further, the first swing frequency is larger than the second swing frequency, which indicates that the pumping unit fails in the swing stop process, and an alarm can be given.
S1032, alarming step: and alarming when the pumping unit is in an abnormal stop state.
It can be understood that the oil pumping unit alarms in time when in an abnormal stop state, so that an operator can check the oil pumping unit in time.
In an alternative embodiment, the method further comprises an alarm rule configuration step: and setting different alarm types according to different alarm service scenes.
In an alternative embodiment, setting different alarm types according to different alarm service scenarios includes the alarm type being a first alarm type when the alarm service scenario is an abnormal stop;
and when the alarm service scene is a swinging type stop, the alarm type is a second alarm type.
It can be understood that the method provided by the embodiment of the invention can alarm when the system is abnormally stopped, and can also alarm under the condition that the swing stopping time is changed, and the alarm under the swing stopping condition is likely to be an attempt alarm during the self-learning period of the system instead of the failure of the pumping unit, so that the alarm types can be distinguished according to the two different alarm service scenes, and the processing efficiency of the operation personnel on the alarm conditions can be improved.
As an example, when a new alarm type occurs, an alarm type is newly built and the newly built alarm type is monitored in real time.
In an alternative embodiment, the method further comprises the step of alarm delay configuration: and configuring the delay of different service alarms according to preset alarm standards and different alarm services.
It can be understood that the alarm for stopping swinging is not likely to be caused by the failure of the pumping unit, and the delay of different service alarms is configured through preset alarm standards and alarm services. As an example, the delay of the preset time may be set for the alarm of the swing stop, and for example, the alarm may be delayed for 2 seconds later. Or according to a preset standard, namely under the type of the swing type stop alarm, when the alarm times reach the preset times, for example, after 2 times, 3 times or more than 4 times, the alarm is carried out. Therefore, not only can the timely monitoring of various alarms be achieved, but also the resource waste caused by the alarm condition processing is avoided.
In an alternative embodiment, according to preset alarm standards and different alarm services, configuring delays of different service alarms, including delaying a first preset time when an alarm service scene is an abnormal stop;
when the alarm service scene is a swing type stop time delay second preset time;
wherein the first preset time is less than the second preset time.
It will be appreciated that there are many types of abnormal stops, such as a power outage stop, a physical damage stop of a pumping unit related mechanism, or a stop caused by other reasons, and that a delay alarm may be set for the stop alarm depending on the reason of the stop. As an example, the delay alarm time may be set for a power outage stop, the delay alarm time may be set for physical damage of a pumping unit related mechanism, the delay alarm time may be set for an abnormal stop of other reasons for reference by an operator, and then corresponding processing measures may be taken for the stopping of different reasons. Or the repeated alarm is set in a delayed mode, and the alarm processing effect is effectively improved on the premise of ensuring that the alarm is not missed. It should be noted that, setting different alarm delays for different reasons can be set according to the needs of the user, and the embodiments of the present invention do not limit the above-mentioned various times.
As another example, the second preset time of the alarm delay of the swing type stop may be matched with the time of the preset number of times of the alarm under the swing type stop, for example, when the swing time is unchanged all the time after 2 times of alarm, the swing time is counted and is not changed, so that the pumping unit is not failed and does not need to process the alarm under the condition, but alarm information is sent out at this time, the time of the alarm delay may be the time corresponding to 2 times of alarm, when the time exceeds 2 times, the alarm is sent out again, and if the alarm is not sent out after 2 times, the alarm information does not need to be processed. Thus, unnecessary alarms are reduced, and the processing efficiency of alarm events is improved.
In an alternative embodiment, when a new alert service is present, the new alert service is compared with the types of already existing alert services, generating an alert delay for the new alert service.
In an alternative embodiment, the method provided by the embodiment of the invention can also comb the alarm problem, set the alarm setting level for the severity of the problem and the time limit of the problem treatment, namely, can set the first priority for the comparative emergency alarm, and can process the alarm with high priority when a plurality of alarms exist, namely, process the alarm according to the priority of the preset alarm processing level, thus, the alarm can be timely and effectively time-limited, and the alarm processing efficiency is improved.
As an example, when a new alarm problem occurs, the severity of the alarm problem is analyzed and compared to existing alarms, and all alarm problem handling priorities are reordered to generate a new handling level priority, and the handling is performed according to the new handling level priority.
