Description

Technical Field

[0001] The present invention relates to the technical field of oil well detection and control, and particularly relates to a method for automatically starting and stopping the dynamic liquid level of an oil well. Background Art

[0002] With the development of oil industry technology, related oil well exploration, monitoring, and control technologies have been fully developed. Therefore, more and more oil mining enterprises have further improved their requirements for safe mining. Currently, common safety control systems often need to cooperate with multiple sensors to monitor the operating status of various mining equipment in real time, and after unified streamlining, the data is uploaded to the manual review department for manual review. As a result, problems cannot be discovered and corresponding emergency treatments cannot be carried out immediately. Often, only after manual review can further detailed control be carried out. Therefore, most mining equipment is equipped with multiple redundant emergency structures to avoid or reduce negative impacts, resulting in a relatively high overall equipment cost and being relatively easy to damage. Summary of the Invention

[0003] The purpose of the present invention is to provide a method for automatically starting and stopping the dynamic liquid level of an oil well, which solves the technical problems of poor emergency handling efficiency and poor safety protection effect in the prior art, and realizes the technical effects of improving the emergency handling efficiency and the overall safety protection effect.

[0004] In order to achieve the above invention purpose, the technical solution adopted by the present invention is as follows:

[0005] A method for automatically starting and stopping the dynamic liquid level of an oil well includes a central data collection and processing module, a pumping unit operation monitoring module, and an oil well status monitoring module. The central data collection and processing module can collect the data information obtained by the pumping unit operation monitoring module and the oil well monitoring module through data lines or wireless signals. The central data collection and processing module will identify the acquired data. When abnormal data is identified, it will be sent to the emergency processing module and the review module for emergency management and secondary review respectively. The emergency processing module includes valve control, pressure control, and emergency stop control. The secondary review will contact the operator through wireless signals for manual review and then perform manual emergency processing. The pumping unit operation monitoring module can monitor the motor operating status, radial movement of the sucker rod, and axial deflection of the sucker rod through multiple sensors. The oil well status monitoring module can monitor the temperature, pressure, and liquid level status in the oil well through multiple sensors. The pumping unit operation monitoring module and the oil well status monitoring module will send the corresponding monitoring data to the local storage module for data retention.

[0006] As an improvement, the central data collection and processing module can obtain corresponding data according to the classification of the device. The emergency processing module will obtain the data change threshold of the corresponding device through the central data collection and processing module. When the measured data exceeds the threshold, the corresponding emergency processing program will be started. The secondary review will judge the data that can cause this impact based on the current abnormal data, and conduct a reverse query and review of the data content. Such data will be reviewed and screened manually. After the manual review is completed, an operation instruction will be issued to the emergency processing module through the manual emergency processing module.

[0007] As an improvement, the emergency processing module will retain and record the alarm processing process information. The processing process information includes the data change data of each device, the manually judged and reviewed data, and the subsequent device operation status data. The central data collection and processing module will classify and save such data information, and precisely adjust the threshold information according to the data change characteristics. At the same time, it will also automatically generate an emergency device processing program based on the overall processing process record. When encountering similar problems, the processing program can be automatically retrieved for emergency processing.

[0008] As an improvement, the operation monitoring module of the pumping unit further includes sensor data processing. The sensor data processing can calculate the actual operation status of the sucker rod through modeling of the operation status data of multiple sucker rods. After obtaining the modeling data, the information can be uploaded to the central data collection and processing module, and then the operation simulation is carried out to accurately obtain the start-stop status of the sucker rod structure.

[0009] As an improvement, the operation monitoring module of the pumping unit further includes key point pressure monitoring. The pressure monitoring identifies the pressure conditions at each operation structure position through a pressure sensor, thereby further improving the data measurement accuracy.

[0010] As an improvement, the oil well status monitoring module further includes flow monitoring. The flow monitoring supervises the internal liquid by installing a flow meter on the transportation pipeline. By recording the flow rate data, it is convenient to assist in verifying the operation status of the pumping unit. The operation monitoring module of the pumping unit and the oil well status monitoring module can simplify the data, pre-screen the suspected problem data, and then transmit the data to the central data processing and collection module, thereby improving the data processing efficiency.

[0011] The beneficial effects of the present invention are as follows: By setting up the central data collection and processing module, various detection data can be quickly obtained, so that emergency processing can be carried out immediately according to the data content, which is convenient for controlling the start and stop of the device to ensure the normal operation of the device. By setting up the secondary review and retaining the record of the processing process information, a corresponding problem processing program can be generated after accurate manual review, so that the corresponding processing program can be retrieved immediately when the same problem occurs next time, thereby further improving the processing effect and speed.

[0013] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0014] It should be noted that the terms "first" and "second" in the present application are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present application, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined. In addition, the terms "include" and "have" and any variations thereof are intended to cover non - exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products or devices.

[0015] As Figure 1As shown in the figure, an automatic start-stop method for the dynamic liquid level of an oil well includes a central data collection and processing module, a pumping unit operation monitoring module, and an oil well status monitoring module. The central data collection and processing module can collect the data information obtained by the pumping unit operation monitoring module and the oil well monitoring module through data lines or wireless signals. The central data collection and processing module will identify the acquired data. When abnormal data is identified, it will be sent to the emergency processing module and the review module for emergency management and secondary review respectively. The emergency processing module includes valve control, pressure control, and emergency stop control. The secondary review will contact the operator through wireless signals for manual review and then perform manual emergency processing. The pumping unit operation monitoring module can monitor the motor operation status, radial movement of the sucker rod, and axial deflection of the sucker rod through multiple sensors. The oil well status monitoring module can monitor the temperature, pressure, and liquid level status in the oil well through multiple sensors. The pumping unit operation monitoring module and the oil well status monitoring module will send the corresponding monitoring data to the local storage module for data retention. The central data collection and processing module can be equipped with a wireless signal transceiver device and can directly communicate with the administrator terminal through wireless signals, so as to conveniently notify the administrator for remote control and early warning in the first time.

[0016] The central data collection and processing module can classify and obtain the corresponding data according to the device. The emergency processing module will obtain the data change threshold of the corresponding device through the central data collection and processing module. When the measured data exceeds the threshold, the corresponding emergency processing procedure will be started. The secondary review will judge the data that can cause this impact based on the current abnormal data and conduct a reverse query and review of the data content. Such data will be reviewed and screened manually. After the manual review is completed, an operation instruction will be issued to the emergency processing module through the manual emergency processing module. The emergency processing module will retain and record the alarm processing process information. The processing process information includes various data change data of the device, manual judgment and review data, and subsequent device operation status data. The central data collection and processing module will classify and save such data information, accurately adjust the threshold information according to the data change characteristics, and at the same time automatically generate an emergency device processing program according to the overall processing process record. When encountering similar problems, the processing program can be automatically retrieved for emergency processing. The program can be pre-programmed by technicians, and the corresponding warning thresholds can be estimated by combining various data. When the uploaded data is identified as exceeding the threshold, the corresponding processing program can be retrieved, and the processing program can be modified and adjusted.

[0017] The operation monitoring module of the pumping unit further includes sensor data processing. The actual operating condition of the sucker rod can be calculated through modeling of the operating state data of multiple sucker rods. After obtaining the modeling data, the information can be uploaded to the central data collection and processing module, and then operation simulation can be carried out to accurately obtain the start-stop state of the sucker rod structure. The operation monitoring module of the pumping unit also includes key point pressure monitoring. The pressure monitoring can identify the pressure conditions at each operating structure position through pressure sensors, thereby further improving the data measurement accuracy. The oil well state monitoring module also includes flow monitoring. The flow monitoring is carried out by installing a flowmeter on the transportation pipeline to monitor the internal liquid. By recording the flow velocity and flow rate data, it is convenient to assist in verifying the operating state of the pumping unit. The operation monitoring module of the pumping unit and the oil well state monitoring module can simplify the data, pre-screen the suspected problem data, and then transmit the data to the central data processing and collection module, thereby improving the data processing efficiency. The data reduction and screening can automatically filter out the data with small changes, directly intercept and record the data with large changes and upload them. When the central data processing and collection module receives abnormal data with large changes, it will directly start the corresponding emergency processing module, thereby controlling the start and stop of the valve, and at the same time start monitoring the redundant design structure to ensure the stable operation of the entire system.

[0018] When in use, after the administrator completes the sensor settings for each device, the data can be uploaded to the central data collection and processing module through a line or wireless transmission. At this time, the administrator can obtain the data reference table and the real-time device operating state through the terminal for monitoring; when the device has an abnormal state, the sensor will obtain the corresponding data, and quickly upload it to the central data collection and processing module after screening. At this time, after the central data collection and processing module makes a distinction, it will quickly call the emergency procedure and control the start and stop of the device. At the same time, it will also transmit the abnormal data back to the administrator's terminal for manual data verification. At this time, the administrator can perform manual emergency processing according to the actual situation to ensure the normal operation state of the device; during this process, all processing information and data will be stored and recorded, and the central data collection and processing module will automatically adjust the threshold range and the corresponding control program.

[0019] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
