Description
Technical Field
The invention relates to the field of fault monitoring of oilfield well site equipment. In particular, the present invention relates to wellsite equipment monitoring systems and methods for monitoring wellsite equipment monitoring areas for anomalies.
Background
In well site operation, in order to ensure that equipment used in the fracturing operation process runs safely, a specially-assigned person needs to be arranged in a well site for operation to inspect well site equipment and pipelines so as to find out abnormality or danger such as equipment abnormality, manifold jitter and manifold puncture in time. In some well sites, the abnormality of the equipment easily causes serious safety accidents, so that the safety of inspection personnel is also risked.
In order to reduce the danger faced by inspection personnel in the equipment inspection process, the video monitoring technology is gradually applied to monitor the abnormity of the equipment. The video monitoring of the core components and lines of fracturing equipment, wellheads, manifolds or motors, gearboxes, motors, transformers, frequency converters, and power cables is performed by installing a suitable number of camera systems at appropriate locations on the wellsite. The video signals generated in the process can be transmitted to an instrument device or a monitoring room, and an inspector can inspect important equipment, important areas or core components of the well site in real time through the instrument device or the monitoring room.
However, such a video monitoring system needs to rely heavily on inspection personnel and experience thereof to monitor and check the abnormality or malfunction of the equipment. Meanwhile, as more pictures need to be monitored, inspection personnel may miss some abnormalities or make a fault type judgment.

Detailed Description
Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings. What has been described herein is merely a preferred embodiment in accordance with the present invention and other ways of practicing the invention will occur to those skilled in the art and are within the scope of the invention.
Referring to FIG. 1, a wellsite equipment monitoring system 100 is illustratively shown in accordance with the present disclosure. As can be seen in FIG. 1, the wellsite equipment monitoring system 100 may include a dynamic capture module 10 for capturing via video information whether abnormal dynamic activity is present in an equipment monitored area, a temperature detection module 20 for monitoring whether a temperature abnormality is present therein by detecting a temperature distribution of the wellsite equipment monitored area, and an information processing module 30 for determining a type of fault abnormality in the wellsite equipment monitored area in conjunction with output information of the dynamic capture module and the temperature detection module.
Within the scope of the present invention, the dynamic capture module 10 may include a video acquisition unit 11 for acquiring video signals of the wellsite equipment monitoring area and a dynamic analysis unit 12 for analyzing the acquired video signals. Specifically, the dynamic analysis unit 12 analyzes the characteristics, for example, the pixels, of the current video signal acquired by the video acquisition unit, and determines that there is abnormal dynamic activity in the wellsite equipment monitoring area currently, for example, when the pixels of the current video signal exceed a preset pixel threshold (of course, other analysis methods may be adopted).
In addition, the temperature detection module 20 may include a temperature acquisition unit 21 to acquire a temperature distribution of the wellsite equipment monitoring area through a thermal imaging principle and a temperature analysis unit 22 to find temperature information of the wellsite equipment monitoring area based on the temperature distribution acquired by the temperature acquisition unit 21 and to determine whether there is a temperature abnormality based on the temperature information. The temperature information includes a maximum temperature and/or a minimum temperature and/or an average temperature, and a specific position in the well site equipment monitoring area corresponding to the maximum temperature and/or the minimum temperature. In the scope of the present invention, the temperature acquisition unit 21 acquires the infrared radiation energy of the object to be measured by using a thermal imaging principle or by using an infrared probe or the like. In principle, there is a corresponding relationship between the radiation energy and the temperature, and the difference of the infrared radiation energy can be represented by different gray scales through a related algorithm, so as to display the temperature distribution of the object to be measured on the graph. On the basis, the temperature analysis unit 22 can analyze the obtained maximum temperature and/or minimum temperature and/or average temperature of the wellsite equipment monitoring area and the area corresponding to the maximum temperature and/or minimum temperature and judge whether temperature abnormality exists in the wellsite equipment monitoring area currently. Specifically, the temperature analysis unit 22 may determine that there is a temperature abnormality in the wellsite equipment monitoring area and a specific location of the temperature abnormality if the maximum temperature and/or the minimum temperature and/or the average temperature exceeds a corresponding temperature threshold set in advance (i.e., the current maximum temperature exceeds a temperature threshold corresponding to the maximum temperature and/or the current minimum temperature exceeds a temperature threshold corresponding to the minimum temperature and/or the current average temperature exceeds a temperature threshold corresponding to the average temperature).
The information processing module 30 analyzes and judges the abnormality, more precisely, the fault type of the equipment monitoring area under the condition that the dynamic capturing module 10 is combined to judge whether abnormal dynamic activity exists in the wellsite equipment monitoring area and the temperature detecting module 20 analyzes and judges whether temperature abnormality exists in the wellsite equipment monitoring area.
Within the scope of the invention, the predetermined pixel threshold is determined with reference to video pixels of the monitored area of the device in the case of normal operation. Similarly, corresponding temperature thresholds are determined with reference to corresponding temperatures of the wellsite equipment monitored area under normal operating conditions and an ambient temperature of the wellsite equipment monitored area.
In the scope of the present invention, the analyzing and determining of the fault type by the information processing module 30 specifically means that the information processing module 30 determines the fault type of the wellsite equipment monitoring area according to different information output by the dynamic capture module 10 and the temperature detection module 20. In other words, here, in the case where the dynamic capture module 10 determines that there is no abnormal dynamic activity in the equipment monitoring area and the temperature detection module 20 determines that there is a temperature abnormality in the equipment monitoring area, the information processing module 30 may determine that there may be a failure of operating temperature abnormality of some equipment in the wellsite equipment monitoring area, for example; in the case where the dynamic capture module 10 determines that there is abnormal dynamic activity in the wellsite equipment monitoring area and the temperature detection module 20 determines that there is no temperature abnormality in the wellsite equipment monitoring area, the information processing module 30 may determine that there is a fault such as abnormal vibration in the equipment monitoring area; and in the case where the dynamic capture module 10 determines that there is abnormal dynamic activity in the equipment monitoring area and the temperature detection module 20 determines that there is also temperature abnormality in the equipment monitoring area, the information processing module 30 may determine that a fault occurs, such as a person intruding into the equipment monitoring area or a puncture in the equipment pipeline. Of course, in some other embodiments of the present invention, the information processing module 30 may also determine the type of failure of the wellsite equipment monitoring area separately from the different information output by the motion capture module 10 and the temperature detection module 20. In other words, the information processing module 30 may determine the type of failure in the wellsite equipment monitoring area based on abnormal dynamic activity output by the dynamic capture module 10 or based on temperature anomaly information output by the temperature detection module 20, provided that either one of the two is sufficient to determine the type of failure.
In some embodiments of the present invention, the motion capture module 10 may further comprise, for example, a video signal repository 13 configured to store a series (i.e., in a time sequence) of video signals captured by the video capture unit 11 of the motion capture module 10. In this case, the dynamic analysis unit 12 determines whether there is currently abnormal activity in the equipment monitoring area by comparing the current video signal of the equipment monitoring area acquired by the video acquisition unit 11 with the acquired video signal at the previous time point or the previous several time points stored in the video signal storage 13. For example, the motion analysis unit 12 may compare a currently captured video signal with a video signal captured at a previous time point or several previous time points, and analyze a pixel change of the video signal at a corresponding portion at which abnormal dynamic motion is determined to exist in the case where the pixel change at the corresponding portion exceeds a previously set deviation pixel threshold. That is, the dynamic analysis unit 12 can determine the specific position where abnormal activity occurs from the position where a pixel exceeding the pixel deviation threshold value occurs.
In some embodiments of the present invention, the temperature detection module 20 may further include a temperature information repository 23 configured to store temperature information (i.e., the maximum and/or minimum and/or average temperatures and their respective corresponding specific locations) calculated or analyzed by the temperature analysis unit 22 at a time point or points prior to the wellsite equipment monitoring area. The temperature analysis unit 22 calculates the current maximum and/or minimum temperature and/or average temperature from the current temperature distribution of the wellsite equipment monitoring area collected by the temperature collection unit 21 and compares it with the corresponding temperature information stored in the temperature information repository 23 at the previous time point or previous time points. Specifically, the temperature analysis unit determines that a temperature anomaly exists in the wellsite equipment monitoring area, for example, when the difference between the current maximum temperature and/or minimum temperature and/or average temperature and the maximum temperature and/or minimum temperature and/or average temperature at the previous time point or previous time points exceeds a preset temperature deviation threshold. Of course, while analyzing the maximum temperature and/or the minimum temperature, the specific location where the temperature abnormality occurs may be determined by combining the temperature distribution acquired by the temperature acquisition unit 21.
In some embodiments of the present invention, information handling module 30 also considers the relationship between the specific portion of the abnormal dynamic activity and the specific portion of the temperature abnormality to determine the type of fault. That is, for example, when a specific part of an abnormal activity coincides with a specific part of a temperature abnormality, the information processing module 30 may determine that a puncture or a human intrusion has occurred at a pipe or a manifold of the equipment, and when the two parts do not coincide, an abnormal vibration of the equipment and a human intrusion may occur at the same time.
In some embodiments of the present invention, wellsite equipment monitoring system 100 may further include an alarm module 40 that generates an alarm if information processing module 30 determines a type of fault present within the equipment monitoring area. In addition, wellsite equipment monitoring system 100 also includes a display unit 50 that displays the collected video signals and temperature profiles.
The invention also relates to a well site equipment monitoring method for monitoring the abnormality of the well site equipment monitoring area, which comprises the following steps:
s1: collecting video signals of the equipment monitoring area;
s2: analyzing and judging whether abnormal dynamic activities exist in the equipment monitoring area or not based on the acquired video signals;
specifically, by analyzing the characteristics, such as pixels, of the acquired current video signal, for example, when the pixels of the current video signal exceed a preset pixel threshold (of course, other analysis methods may be adopted), it is determined that abnormal dynamic activity exists in the wellsite equipment monitoring area.
S3: collecting a temperature profile in the wellsite equipment monitoring area;
s4: acquiring temperature information in the wellsite equipment monitoring area based on the acquired temperature distribution analysis, wherein the temperature information comprises a maximum temperature and/or a minimum temperature and/or an average temperature and a specific position in the wellsite equipment monitoring area corresponding to the maximum temperature and/or the minimum temperature;
s5: determining whether a temperature anomaly exists in the wellsite equipment monitoring area based on the temperature information;
specifically, the infrared radiation energy of the measured object is collected by utilizing the thermal imaging principle or by using an infrared probe and other devices. In principle, there is a corresponding relationship between the radiation energy and the temperature, and the difference of the infrared radiation energy can be represented by different gray scales through a related algorithm, so as to display the temperature distribution of the object to be measured on the graph. On the basis, the obtained current highest temperature and/or lowest temperature and/or average temperature of the wellsite equipment monitoring area and the area corresponding to the highest temperature and/or the lowest temperature are analyzed, and whether temperature abnormality exists in the wellsite equipment monitoring area currently is judged. Specifically, for example, in the case that the maximum temperature and/or the minimum temperature and/or the average temperature exceeds a preset corresponding temperature threshold (i.e., the current maximum temperature exceeds a temperature threshold corresponding to the maximum temperature and/or the current minimum temperature exceeds a temperature threshold corresponding to the minimum temperature and/or the current average temperature exceeds a temperature threshold corresponding to the average temperature), it is determined that the wellsite equipment monitoring area has a temperature abnormality and a specific part with the temperature abnormality.
S6: determining a type of failure of the wellsite equipment taking into account both the conclusion of the abnormal dynamic activity and the temperature anomaly.
In the context of the present invention, the predetermined pixel threshold is determined with reference to video pixels of the wellsite equipment monitoring area during normal operating conditions. Similarly, corresponding temperature thresholds are determined with reference to corresponding temperatures of the wellsite equipment monitored area under normal operating conditions and an ambient temperature of the wellsite equipment monitored area.
In the scope of the present invention, the analyzing and determining the fault type specifically refers to determining the fault type of the wellsite equipment monitoring area according to different abnormal dynamic activity information and temperature abnormality information. In other words, where it is determined that there is no abnormal dynamic activity in the wellsite equipment monitoring area and a temperature anomaly in the wellsite equipment monitoring area, it may be determined, for example, that the wellsite equipment monitoring area may have a failure with an operating temperature anomaly of certain equipment; under the condition that abnormal dynamic activity exists in the wellsite equipment monitoring area and temperature abnormality does not exist in the wellsite equipment monitoring area, for example, the occurrence of faults such as abnormal vibration and the like in the wellsite equipment monitoring area can be judged; and when abnormal dynamic activity exists in the wellsite equipment monitoring area and temperature abnormality also exists in the wellsite equipment monitoring area, faults such as human intrusion in the wellsite equipment monitoring area or equipment pipeline puncture can be judged. Of course, in some other embodiments of the present invention, the type of failure of the wellsite equipment monitoring area may be determined separately for abnormal dynamic activity and temperature anomaly information. In other words, the type of failure of the wellsite equipment monitoring area may be determined based on abnormal dynamic activity or based on temperature anomaly information, provided that one of the two is sufficient to determine the type of failure.
In some embodiments of the present invention, in determining the abnormal dynamic activity, comparing a currently acquired video signal with a video signal acquired at a previous time point or a few previous time points, and analyzing a pixel change of the video signal at a corresponding portion, determining that the abnormal dynamic activity exists at the corresponding portion if the pixel change at the corresponding portion exceeds a preset deviation pixel threshold. That is, the specific location where abnormal activity occurs can be determined from the location where a pixel exceeding the pixel deviation threshold occurs.
In some embodiments of the invention, when the temperature anomaly is determined, the acquired current maximum temperature and/or minimum temperature and/or average temperature is compared with the maximum temperature and/or minimum temperature and/or average temperature at the previous time point or previous time points, and if the corresponding temperature difference exceeds a preset deviation temperature threshold value, the temperature anomaly of the wellsite equipment monitoring area is determined. Of course, when analyzing the highest temperature and/or the lowest temperature, the specific location where the temperature abnormality occurs may be determined by combining the collected temperature distribution.
In some embodiments of the invention, the type of fault is also determined taking into account a relationship between the specific portion of the abnormal dynamic activity and the specific portion of the temperature abnormality. Specifically, for example, when a specific part of abnormal activity coincides with a specific part of abnormal temperature, it may be determined that a leak or a human intruder has occurred in a pipe or a manifold of the equipment, and when the two parts do not coincide, there may be a possibility that abnormal vibration of the equipment and human intrusion may occur at the same time.
The wellsite equipment monitoring system and method disclosed by the invention can be used for dynamically comparing and detecting wellsite equipment, carrying out fault monitoring on certain key parts (such as manifolds or engines which are easy to vibrate) by combining thermal imaging and dynamic capturing, and automatically carrying out early warning when faults occur. The monitoring mode reduces labor cost of well site monitoring and improves efficiency.
