Description

Technical Field

[0001] This application belongs to the field of oil and gas technology, specifically relating to a leak monitoring device and manifold. Background Technology

[0002] With the continued recovery and improvement of China's economy, the energy industry is accelerating its transformation, and continuous exploration of industrial restructuring and upgrading is underway, with the implementation of concepts such as intelligence, greenness, efficiency, and safety. Amid the ongoing global warming climate crisis, the energy industry is becoming increasingly segmented, with overcapacity becoming a prominent issue. Competition within the oil fracturing industry is intensifying, prompting companies to explore suitable development paths. Technological iteration is driving the maturation of intelligent fracturing well sites in China, and intelligent equipment is being increasingly used in oil and gas well sites. Operators at intelligent well sites can monitor fracturing operations through cameras and other means on the control interface, understanding the status of well site equipment and receiving early warnings of abnormal equipment conditions.

[0003] During operation, leakage typically begins as micro-leakage, which is difficult to observe. The fluid continues to flow along the leakage path, and after a period of time, the high-pressure fluid will cause erosion, enlarging the crack. As the sealing crack enlarges, the fluid jets at the crack due to the pressure difference, forming turbulence. The medium in the turbulence impacts and rubs against the sealing surface, causing a large-flow leakage. Once a large-flow leakage occurs during operation, it will directly affect the operation process, causing economic losses to the on-site construction and posing safety risks. Utility Model Content

[0004] The purpose of this application is to provide a leakage monitoring device and manifold that can solve the problem of large-flow leakage in the manifold.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] This application provides a leakage monitoring device for monitoring leaks at manifold connections. The leakage monitoring device includes: a leakage monitoring component, a control component, and an anomaly alert component.

[0007] The leakage monitoring component is used to be installed at the connection of the manifold;

[0008] The leakage monitoring component is electrically connected to the control component;

[0009] The anomaly alert component is electrically connected to the control component;

[0010] The control component is used to control the anomaly alert component to issue a leakage alert signal when the leakage monitoring component detects a leak at the connection.

[0011] This application embodiment also provides a manifold, including: multiple pipe units and the above-mentioned leakage monitoring device;

[0012] Each of the tube units is provided with a connection end at its end, and two adjacent tube units are connected through their respective connection ends;

[0013] The leakage monitoring component is located at the connection point of each of the two adjacent pipe units.

[0014] In this embodiment, the leak monitoring component can monitor the manifold connection in real time and send the monitored information to the control component. Thus, in the early stages of leakage at the manifold connection, when it is in the micro-leakage stage, the leak monitoring component can detect the leakage. Upon detection of leakage at the connection, the control component can control the anomaly alert component to issue a leak warning signal, prompting workers to pay attention to the leak and implement preventative measures. This effectively prevents the leak from escalating into a gushing situation, ensuring the smooth operation of the work and avoiding significant economic losses and safety risks.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0032] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0033] refer to Figures 1 to 4 This application discloses a leakage monitoring device 01 for monitoring leaks at the connection points of a manifold 02 to prevent large-flow leaks from affecting normal operations and causing significant economic losses and safety risks. The disclosed leakage monitoring device 01 includes a leakage monitoring component 10, a control component 20, and an anomaly alert component 30.

[0034] Considering the need to transport high-pressure fluid over a long distance via manifold 02, it was designed to be composed of multiple sections. However, due to assembly errors, poor sealing, and aging of seals, leaks can easily occur at the joints between adjacent sections after a period of operation. Initially, leakage occurs at the joints, where high-pressure fluid slowly seeps outwards along the gaps, forming droplets that drip from manifold 02 or flow along its walls. Because the leakage flow is very small, it is difficult to detect.

[0035] However, after a period of leakage, the high-pressure fluid will continuously erode the leaking cracks, causing the cracks to enlarge. As the cracks enlarge, the high-pressure fluid will be ejected from the cracks under high pressure, forming turbulence. The high-pressure fluid in the turbulence will continuously impact and rub against the cracks, causing the cracks to become larger and larger, resulting in a large leakage of high-pressure fluid. This will directly affect normal operations, cause significant economic losses to the construction, and pose safety risks.

[0036] Based on the above, in this embodiment of the application, the leakage monitoring component 10 can be installed at the connection of the manifold 02 to monitor the leakage at the connection of the manifold 02 in real time, so as to determine whether leakage has occurred. Optionally, the leakage monitoring component 10 can be installed on the outside of the connection of the manifold 02 or on the inside of the connection of the manifold 02, depending on the actual working conditions.

[0037] For example, the leak detection component 10 can be installed to the manifold 02 by means of threaded connection, magnetic attraction, adhesive, welding, snap-fit, etc.

[0038] It should be noted that the leak monitoring component 10 can not only monitor small-flow leaks such as seepage at the connection point in real time, but also large-flow leaks such as jetting in real time.

[0039] The leakage monitoring component 10 is electrically connected to the control component 20, and is used to send the detected leakage situation to the control component 20 in the form of a signal. In addition, the control component 20 can also send control signals to the leakage monitoring component 10. It should be noted here that the electrical connection in this embodiment can refer to the ability for signal transmission between two devices, such as the transmission of control signals, the transmission of electrical signals, etc.

[0040] The anomaly alert component 30 is electrically connected to the control component 20 to receive control signals sent by the control component 20. Specifically, when the leakage is a small-flow leak such as seepage, the alert from the anomaly alert component 30 can be weak; when the leakage is a large-flow leak such as jetting, the alert from the anomaly alert component 30 can be strong.

[0041] For example, when a small-flow leak occurs, such as seepage, the anomaly alert component 30 may issue a first alarm, a first light, or send an alert signal at a first frequency; when a large-flow leak occurs, such as jetting, the anomaly alert component 30 may issue a second alarm, a second light, or send an alert signal at a second frequency; and the decibel level of the first alarm is lower than that of the second alarm, or the first light is dimmer than the second light, or the first frequency is lower than the second frequency; of course, it may also be at least two of the alarm, light, and alert frequency. Thus, different leak situations can be addressed according to the form of the leak alert signal issued by the anomaly alert component 30.

[0042] In this embodiment, the control component 20 is used to control the abnormality alert component 30 to issue a leakage alert signal when the leakage monitoring component 10 detects leakage at the connection. Optionally, the control component 20 can be a PLC control component.

[0043] In this embodiment, the leakage monitoring component 10 can monitor the connection of the manifold 02 in real time and send the monitored information to the control component 20. Thus, in the initial stage of leakage at the connection of the manifold 02, when it is in the micro-leakage stage, the leakage monitoring component 10 can detect the leakage at the connection of the manifold 02. When the leakage monitoring component 10 detects the leakage at the connection of the manifold 02, the control component 20 can control the abnormality reminder component 30 to issue a leakage reminder signal, so that the staff can pay attention to the leakage at the connection of the pipeline and take measures to deal with the leakage in advance. This effectively prevents the leakage at the connection of the manifold 02 from developing into a jetting situation, thus ensuring the normal operation of the work and avoiding major economic losses and safety risks.

[0044] In some embodiments, a leakage channel 023 may be provided at the connection point to collect high-pressure fluid leaking from the connection point, preventing the high-pressure fluid from leaking to other locations and affecting monitoring results. Exemplarily, the leakage channel 023 may extend radially along the manifold 02 and axially, such that the end of the leakage channel 023 extends to the contact surface of two adjacent pipe sections. Thus, when high-pressure fluid leaks from the contact surface of two adjacent pipe sections, it can flow into the leakage channel 023 and be collected through it.

[0045] Optionally, the leak detection component 10 may include a pressure monitoring element with a monitoring end that is configured to correspond to the leak channel 023. Based on this configuration, when a leak occurs at the connection, the leaking high-pressure fluid flows along the leak channel 023 to contact the monitoring end of the pressure monitoring element, thereby exerting pressure on the monitoring end. The pressure monitoring element can then send the monitored pressure data to the control component 20. The control component 20 can compare the pressure data monitored by the pressure monitoring element with a preset pressure value. When the pressure data reaches or exceeds the preset pressure value, a leak is determined to have occurred at the connection.

[0046] Alternatively, the pressure monitoring element can be a pressure sensor, pressure transmitter, etc.

[0047] In some more specific embodiments, the pressure monitoring element can be installed at the outlet of the leakage channel 023 by means of a threaded connection to prevent the pressure monitoring element from detaching from the manifold 02 under pressure. In addition, a sealed cavity can be formed between the pressure monitoring element and the leakage channel 023 to ensure that the leaked high-pressure fluid can flow into the sealed cavity along the leakage channel 023, thereby allowing the pressure monitoring element to come into contact with the high-pressure fluid.

[0048] It should be noted that when the leakage is a small-flow leak such as seepage, although the monitored pressure data reaches or exceeds the preset pressure value, the first difference between the pressure data and the preset pressure value is small, thus indicating that a small-flow leak such as seepage has occurred at the connection of manifold 02. Conversely, when the leakage is a large-flow leak such as jetting, the second difference between the monitored pressure data and the preset pressure value is large, exceeding the first difference, thus indicating that a large-flow leak such as jetting has occurred at the connection of manifold 02.

[0049] To further improve the reliability of leak monitoring, multiple leak channels 023 can be provided at the connection point, arranged circumferentially along the manifold 02. This allows for the collection of high-pressure fluid leaking from the connection point through multiple leak channels 023. Correspondingly, a pressure monitoring element can be installed at the outlet of each leak channel 023 to achieve multiple pressure leak monitoring points circumferentially at the connection point.

[0050] In some embodiments, the leakage detection component 10 may include a sound monitoring element, which may be disposed at the connection point to monitor the sound at the connection point in order to determine whether a leakage has occurred at the connection point. Optionally, the sound monitoring element may be disposed on the outer peripheral surface of the connection point; of course, it may also be disposed in other locations, which are not specifically limited here.

[0051] For example, the sound monitoring element can be a sound sensor, etc.

[0052] In this embodiment of the application, when a leak occurs at the connection, the high-pressure fluid leaking from the connection will generate impact and friction with the leak gap, thereby producing sound. The sound monitoring element can send the monitored sound data to the control component 20. The control component 20 can compare the decibel of the sound data monitored by the sound monitoring element with a preset decibel value. When the decibel of the sound data reaches or exceeds the preset decibel value, it is determined that a leak has occurred at the connection.

[0053] It should be noted that when the leakage is a small-flow leak such as seepage, although the detected sound data decibel value reaches or exceeds the preset decibel value, the third difference between the sound data decibel value and the preset decibel value is small, thus indicating that a small-flow leak such as seepage has occurred at the connection of manifold 02. Conversely, when the leakage is a large-flow leak such as jetting, the fourth difference between the detected sound data decibel value and the preset decibel value is large, exceeding the third difference, thus indicating that a large-flow leak such as jetting has occurred at the connection of manifold 02.

[0054] To further improve the reliability of leak detection, multiple sound monitoring elements can be installed at the connection point. These multiple sound monitoring elements are distributed along the circumference of the manifold 02 on the outer circumference of the connection point. In this way, multiple sound monitoring elements can be used to detect leaks at multiple points along the circumference of the connection point.

[0055] In some embodiments, the leakage monitoring component 10 may include a vibration monitoring element, which may be disposed at the connection point to monitor vibration at the connection point in order to determine whether a leakage has occurred at the connection point. Optionally, the vibration monitoring element may be disposed on the outer peripheral surface of the connection point; of course, it may also be disposed in other locations, which are not specifically limited here.

[0056] For example, the vibration monitoring element can be a vibration sensor, etc.

[0057] In this embodiment of the application, when a leak occurs at the connection, the leaking high-pressure fluid and the leak gap at the connection will generate impact and friction, which will produce vibration. The vibration monitoring element can send the monitored vibration data to the control component 20. The control component 20 can compare the frequency of the vibration data monitored by the vibration monitoring element with a preset frequency value. When the frequency of the vibration data reaches or is greater than the preset frequency value, it is determined that a leak has occurred at the connection.

[0058] It should be noted that when the leakage is a small-flow leak such as seepage, although the frequency value of the monitored vibration data reaches or exceeds the preset frequency value, the fifth difference between the frequency value of the vibration data and the preset frequency value is small, thus indicating that a small-flow leak such as seepage has occurred at the connection of manifold 02. Conversely, when the leakage is a large-flow leak such as jetting, the sixth difference between the frequency value of the monitored vibration data and the preset frequency value is large, and greater than the fifth difference, thus indicating that a large-flow leak such as jetting has occurred at the connection of manifold 02.

[0059] To further improve the reliability of leak monitoring, multiple vibration monitoring elements can be installed at the connection point. These multiple vibration monitoring elements are distributed along the circumference of the manifold 02 on the outer circumference of the connection point. In this way, multiple vibration monitoring elements can be used to monitor multiple leaks at multiple points along the circumference of the connection point.

[0060] In some embodiments, the leak detection assembly 10 may include a temperature monitoring element, which may be disposed at the connection point to monitor the temperature at the connection point in order to determine whether a leak has occurred. Optionally, the temperature monitoring element may be disposed on the outer peripheral surface of the connection point; of course, it may also be disposed in other locations, which are not specifically limited here.

[0061] For example, the temperature monitoring element can be a temperature sensor, etc.

[0062] In this embodiment, when a leak occurs at the connection, the leaking high-pressure fluid can come into contact with the monitoring end of the temperature monitoring element. The temperature monitoring element can send the monitored temperature data to the control component 20. The control component 20 can compare the frequency of the temperature data monitored by the temperature monitoring element with a preset temperature value. When the temperature data reaches or exceeds the preset temperature value, it is determined that a leak has occurred at the connection. It should be noted that the temperature of the leaking fluid can be lower than the ambient temperature. In this case, the larger the leakage flow rate, the lower the monitored temperature.

[0063] It should be noted that when the leakage is a small-flow leak such as seepage, although the monitored temperature data reaches or exceeds the preset temperature value, the seventh difference between the temperature data and the preset temperature value is small, thus indicating that a small-flow leak such as seepage has occurred at the connection of manifold 02. Conversely, when the leakage is a large-flow leak such as jetting, the eighth difference between the monitored temperature data and the preset temperature value is large, exceeding the seventh difference, thus indicating that a large-flow leak such as jetting has occurred at the connection of manifold 02.

[0064] To further improve the reliability of leak monitoring, multiple temperature monitoring elements can be installed at the connection point. These multiple temperature monitoring elements are distributed along the circumference of the manifold 02 on the outer circumference of the connection point. In this way, multiple temperature monitoring elements can be used to monitor multiple leaks at multiple points along the circumference of the connection point.

[0065] Of course, the leakage monitoring component 10 in this application embodiment may include at least one of a pressure monitoring element, a sound monitoring element, a vibration monitoring element, and a temperature monitoring element, so as to determine whether the manifold 02 has a leak and the extent of the leak based on at least one monitored parameter.

[0066] In some embodiments, the control component 20 may include a power supply 21 and an instrument 22. The instrument 22 is electrically connected to the leak detection element, and the power supply 21 is also electrically connected to the leak detection element. Based on this configuration, the instrument 22 can display the monitoring status of the leak detection element, and the power supply 21 can provide power to the leak detection element.

[0067] For example, the instrument 22 can display the pressure value, sound decibel value, vibration frequency value, temperature value, etc. detected by the leakage monitoring element; the power supply 21 can be used to provide power to the pressure monitoring element, sound monitoring element, vibration monitoring element, and temperature monitoring element respectively.

[0068] In some embodiments, the anomaly alert component 30 may include a display screen to show alert information to staff. For example, when a leak occurs, an alert window may pop up on the screen to alert staff to the leak. For example, the display screen may be a tablet computer monitor, an industrial computer monitor, an operation panel, etc.

[0069] The anomaly alert component 30 may include an alarm that can sound an alarm to alert personnel when a leak occurs. For example, the alarm may be a buzzer or the like.

[0070] The anomaly alert component 30 may include an alarm light that can emit an alarm light to alert personnel to the leak when a leak occurs. For example, the alarm light may be a red light, etc.

[0071] Of course, the abnormality alert component 30 may also include at least two of the following: a display, an alarm, and an alarm light, which helps to improve the success rate of alerts.

[0072] Considering that manifold 02 may include multiple pipe segments with connections between adjacent segments, to achieve comprehensive monitoring of leaks in manifold 02, the leak monitoring device 01 may include multiple leak monitoring components 10. These components 10 are respectively installed at multiple connections in manifold 02. Each component 10 is electrically connected to the control component 20, and each component 10 is pre-numbered within the control component 20. Based on this configuration, the location of the leaking connection can be determined according to the number of the leak monitoring component 10.

[0073] It should be noted that the manifold 02 in the well site can be set in the horizontal plane along the first and second directions perpendicular to the rear. Therefore, each connection of the manifold 02 can have a coordinate number or a numerical number, so that the position of the connection can be determined according to the coordinate number, numerical number, etc.

[0074] In some embodiments, the leak detection component 10 and the control component 20 may be electrically connected via a wired or wireless means to facilitate the transmission of monitoring signals or control signals.

[0075] Based on the aforementioned leak monitoring device 01, this application also discloses a manifold 02, which may include multiple pipe units 021 (i.e., the aforementioned pipe segments) and the leak monitoring device 01. Each pipe unit 021 may have a connection end 022 at its end, and adjacent pipe units 021 are connected through their respective connection ends 022. Leak monitoring components 10 may be located at the connection points of the connection ends 022 of adjacent pipe units 021. With this configuration, multiple leak monitoring components 10 can be used to monitor in real time whether leaks occur at various connections in the manifold 02, thus providing an early warning function.

[0076] Optionally, the aforementioned manifold 02 can be a high-pressure manifold in an intelligent fracturing well site. Of course, it can also be other manifolds 02, which are not specifically limited here.

[0077] In some embodiments, adjacent pipe units 021 can be connected by flanges, unions, clamps, etc. When a flange connection is used, a pressure monitoring element can be installed on the flange to determine the leakage situation through pressure monitoring; when a union connection is used, a sound monitoring element, vibration monitoring element, or temperature monitoring element can be used to detect leakage.

[0078] For example, the end face of the connection end 022 may be provided with a protrusion or a groove, and the connection ends 022 of two adjacent tube units 021 can be reliably connected through the cooperation of the protrusion and the groove.

[0079] In some embodiments, at least one of the connection ends 022 of two adjacent pipe units 021 may be provided with a leakage channel 023, which communicates with the gap between the connection ends 022 of the two adjacent pipe units 021. The leakage monitoring component 10 is correspondingly provided with the leakage channel 023. Based on this arrangement, the leakage monitoring component 10 can be used to monitor the connection between two adjacent pipe units 021 to provide an early warning of leakage in the manifold 02.

[0080] In some embodiments, the manifold 02 may further include a first sealing element 024 and a second sealing element 025. Both the first sealing element 024 and the second sealing element 025 can be sealingly connected between the connection ends 022 of two adjacent pipe units 021. Along the radial direction of the manifold 02, the second sealing element is circumferentially disposed outside the first sealing element. Thus, the first sealing element and the second sealing element together can seal the connection ends 022 between two adjacent pipe units 021.

[0081] The inlet of the leakage channel 023 is located between the first seal 024 and the second seal 025. This ensures that the high-pressure fluid flowing out of the leakage channel 023 can flow into the leakage channel 023 without flowing out, which helps to improve the reliability of leakage monitoring.

[0082] For example, both the first seal 024 and the second seal 025 can be sealing rings.

[0083] In some embodiments, one of the connecting ends 022 of two adjacent pipe units 021 has a protrusion and the other has a groove. The first seal 024 and the second seal 025 can both be disposed between the end face of the protrusion and the bottom of the groove, achieving a seal through the contact and compression of the protrusion and groove. This can achieve a sealing effect of 0-30000 psi, ensuring that high-pressure fluid will not leak to the outside.

[0084] In this embodiment, when the leakage monitoring component 10 detects a leak, it sends a leakage signal to the control component 20 via wired or wireless means. The control component 20 analyzes the signal to determine if an abnormal leakage situation has occurred. When an abnormal leakage situation occurs, the abnormal information can be visually conveyed to the staff through a display or other medium using charts or other means, and alarms and warning lights can be triggered to remind the staff to take measures. In addition, the control component 20 can display the abnormal location on the display according to the number, and display the abnormality troubleshooting suggestions on the display. The operator can assess whether it is necessary to stop the operation based on the abnormal situation and take measures to eliminate the abnormality. Of course, the control component 20 can also archive the abnormal data after eliminating the abnormality, and can also upload it to the cloud.

[0085] In summary, the leakage monitoring device 01 in this embodiment can be applied to the failure monitoring and early warning of manifolds, making it easier for staff to monitor the status of manifold 02 in real time, which helps to reduce well site safety risks, making oil and gas extraction safer, and eliminating the need for staff to patrol for leaks in manifold 02, thus reducing the labor intensity of personnel.

[0086] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
