Description

Technical Field

[0001] This application relates to the field of fracturing manifold skid technology, and in particular to a high and low pressure manifold skid leak detection device and a high and low pressure manifold system. Background Technology

[0002] In fracturing well site operations, high-pressure manifolds are responsible for connecting equipment and transmitting high-pressure fluids; their stability is crucial to operational efficiency and personnel safety. Even minor initial leaks, if not addressed promptly, can lead to serious puncture accidents, causing fluid splashing, operational interruptions, and threatening personnel safety. Therefore, high-pressure manifold leak detection technology, capable of detecting puncture risks in advance, is extremely important. Through image monitoring and intelligent analysis systems, the status of high-pressure manifolds can be monitored in real time, providing timely warnings and enabling operators to take measures before the leak worsens, effectively preventing accidents.

[0003] Currently, fracturing well site operations only deploy a few monitoring cameras in the high-pressure zone, and leaks in high-pressure manifolds and plug valves are identified manually by checking the monitoring data. This method has drawbacks, including limited monitoring coverage, potential safety hazards due to incomplete monitoring, and risks of untimely anomaly identification. Utility Model Content

[0004] Therefore, it is necessary to propose a high- and low-pressure manifold skid leak detection device capable of monitoring the leak status of high-pressure manifolds and stopcock valves. Furthermore, a high- and low-pressure manifold system is also proposed.

[0011] In some embodiments, the drip detection device further includes a vibration isolator disposed between the camera housing and the column, or between the column and the base.

[0012] In some embodiments, the lens axes of the left-facing camera, the front-facing camera, and the right-facing camera are offset by 90 degrees in the circumferential direction.

[0013] A high-low pressure manifold system includes: a high-low pressure manifold skid, the high-low pressure manifold skid includes a support base, a high-pressure manifold assembly and a low-pressure manifold assembly disposed on the support base, a stopcock valve is provided on a branch pipe of the high-pressure manifold assembly, the stopcock valve is connected to a fracturing pump through a high-pressure pipeline; the high-low pressure manifold skid leak detection device is supported on the ground or the support base.

[0014] In some embodiments, the image acquisition module includes a forward-facing camera, a left-facing camera, and a right-facing camera, which face forward, left, and right, respectively. The forward-facing camera acquires image data of the high-pressure pipeline between the fracturing pump and the plug valve in real time, and the left-facing and right-facing cameras acquire image data of the plug valve in real time. In the vertical direction, the axis height of the forward-facing camera is lower than the liquid flow height in the high-pressure pipeline, and the axis height of the left-facing and right-facing cameras is lower than the liquid flow height in the plug valve.

[0015] By utilizing the high and low pressure manifold skid-mounted leak detection device, leak anomalies can be automatically identified through image recognition technology, and alarms can be issued to notify operators, improving the timeliness of anomaly handling and reducing losses. In addition, the leak detection device includes an image acquisition module with a field of view covering the front, left, and rear sides, which can effectively monitor leaks in stopcock valves and high-pressure pipelines, solving the problem of monitoring difficulties caused by the large number of mutually obstructing high-pressure manifolds in existing technologies.

[0028] This application proposes a high and low pressure manifold leak detection device 200 for a high and low pressure manifold skid 100, the two constituting a high and low pressure manifold system.

[0029] refer to Figure 1 To facilitate understanding, the high-low pressure manifold 100 will first be described. The high-low pressure manifold 100 includes a support base 101, a high-pressure manifold assembly 102 mounted on the support base 101, and a low-pressure manifold assembly 103. A plug valve 1021 is installed on a branch pipe of the high-pressure manifold assembly 102, and the plug valve 1021 is connected to the fracturing pump of the fracturing truck via a high-pressure pipeline 1022. The high-pressure manifold assembly 102 is used to connect the fracturing pump of the fracturing truck to the wellhead to deliver and distribute high-pressure fracturing fluid to each wellhead. The low-pressure manifold assembly 103 can be used to handle fluid discharge. The fracturing pump is, for example, a plunger pump, but is not limited to this.

[0030] refer to Figure 2 and Figure 3The high and low pressure manifold skid leak detection device 200 of this application includes a leak detection device 10, an electrical control device 20, and an image processing device 30. The leak detection device 10 includes an image acquisition module 110, whose field of view covers the front, left, and rear sides. The image acquisition module 110 acquires in real time image data of the high pressure pipeline 1022 between the fracturing pump and the stopcock valve 1021 in the front field of view, and acquires in real time image data of the stopcock valve 1021 in the left and right field of view.

[0031] The electrical control device 20 is electrically connected to the drip detection device 10. The electrical control device 20 supplies power to the image acquisition module 110 and transmits image data. The image processing device 30 is used to receive and analyze the image data.

[0032] In this embodiment, the image acquisition module 110 specifically includes a front-facing camera 111, a left-facing camera 112, and a right-facing camera 113. The lenses of the front-facing camera 111, the left-facing camera 112, and the right-facing camera 113 face forward, left, and right, respectively. The front-facing camera 111 acquires real-time image data of the high-pressure pipeline 1022 between the fracturing pump and the plug valve 1021, while the left-facing camera 112 and the right-facing camera 113 acquire real-time image data of the plug valve 1021. The electrical control device 20 is electrically connected to the leak detection device 10, and the electrical control device 20 supplies power to the three cameras and transmits image data. The image processing device 30 is used to receive and analyze the image data.

[0033] The drip detection device 10 includes a front-facing camera 111, a left-facing camera 112, and a right-facing camera 113. The lens axes of the left-facing camera 112, the front-facing camera 111, and the right-facing camera 113 are rotated sequentially by a certain angle in the circumferential direction, so that the lenses of the three cameras face different directions in the circumferential direction, thus each has a different field of view. Figure 4 The field of view of the three cameras is defined as follows: Specifically, the lens axes of the left-facing camera 112, the front-facing camera 111, and the right-facing camera 113 are rotated 90 degrees relative to the former in sequence. This makes the lens axes of the left-facing camera 112 and the front-facing camera 111 perpendicular to each other, and the lens axes of the front-facing camera 111 and the right-facing camera 113 perpendicular to each other. The lens axes of the left-facing camera 112 and the right-facing camera 113 are parallel or lie on the same straight line.

[0034] In this application, references Figure 3 , Figure 5 Left and right are relative to forward. Assuming forward is along the first direction X in the horizontal plane, then left is the second direction Y in the horizontal plane, perpendicular to the first direction X. + The right direction is a third direction Y in the horizontal plane that is perpendicular to the first direction. -A third party to Y - Second direction Y + on the contrary.

[0035] It should also be noted that the three cameras have different lens orientations. The fields of view of the left-facing camera 112, the front-facing camera 111, and the right-facing camera 113 are at least connected in the circumferential direction, thereby eliminating blind spots. However, their fields of view may also overlap to some extent in the circumferential direction. For example, if all three cameras use 112-degree wide-angle lenses, then, taking the left-facing camera 112 and the front-facing camera 111 as examples, the edge areas of their monitored fields of view overlap in the circumferential direction.

[0036] The image acquisition module 110 is not limited to the above-described configuration. For example, if the image acquisition module 110 includes three cameras, the position of their lenses in the circumferential direction and the orientation of the lenses do not need to be strictly set according to the above-described directions, as long as the field of view of the three cameras can cover the front, left, and right sides.

[0037] The specific type of image acquisition module 110 is not limited, as long as it can detect liquid dripping from the pipe, such as a spectral imager or a visible light camera.

[0038] The leak detection device 10 can be mounted on the support base 101 or on the ground. A left-facing camera 112 and a right-facing camera 113 are located between two stopcock valves 1021, with their lenses each pointing towards one of the stopcock valves 1021; the forward-facing camera 111 points towards the high-pressure pipeline 1022 between the stopcock valve 1021 and the fracturing pump. Furthermore, multiple such leak detection devices 10 can be installed on the high- and low-pressure manifold skid 100, thereby enabling monitoring of each stopcock pump and the high-pressure pipeline 1022 in front of it.

[0039] Optionally, the electrical control device 20 includes a DC power supply and a switch. The DC power supply is used to power the drip detection device 10 and the switch, and the switch is used to aggregate the video signals of multiple drip detection devices 10 and transmit them to the image processing device 30.

[0040] The image processing device 30, such as an industrial control computer, is equipped with drip detection software to analyze video data from the camera, identify drip anomalies, and issue an on-screen alarm when an anomaly is detected. Optionally, the image processing device 30 also includes a display screen to show the monitoring screen processed and analyzed in real time. The image processing device 30 uses image recognition technology to automatically identify drip anomalies, which can be achieved using existing image recognition technologies. For example, it determines whether there is a leak by comparing the actual monitoring screen with a standard image.

[0041] In this application, the high and low pressure manifold skid drip identification device 200 can automatically identify drip abnormalities through image recognition technology and issue an alarm to notify the operators, thereby improving the timeliness of abnormal handling and reducing losses. In addition, the drip detection device 10 includes an image acquisition module 110 with a field of view covering the front, left and rear sides, which can effectively monitor the drips of the stopcock valve 1021 and the high pressure pipeline 1022, solving the problem of monitoring difficulties caused by the large number of high pressure manifolds and mutual obstruction in the prior art.

[0042] In some embodiments, reference is made to Figure 5 The drip detection device 10 also includes a base 140, a column 150, and a camera box 160. The bottom of the column 150 is fixed to the base 140. The camera box 160 is fixed to the top of the column 150. A front-facing camera 111, a left-facing camera 112, and a right-facing camera 113 are disposed inside the camera box 160.

[0043] The base 140 is used to mount the high and low pressure manifold skid onto the support 101, or to place it on the ground. The column 150 keeps the camera box 160 at a certain height from the support 101, so that the axial height of the three cameras is adapted to the height of their respective monitored objects.

[0044] Preferably, in the vertical direction, the axis height of the forward-facing camera 111 is lower than the liquid flow height in the high-pressure pipeline 1022, and the axis height of the left-facing camera 112 and the right-facing camera 113 is lower than the liquid flow height in the stopcock valve 1021, thereby better monitoring the liquid dripping status.

[0045] In some embodiments, to facilitate the installation of the drip detection device 10 on the support base 101 of the high and low pressure manifold skid, the base 140 is provided with multiple bolt mounting holes 141 or elongated mounting holes. This design allows the base 140 to be fixed to the bearing housing with bolts. Furthermore, by mates different mounting holes with bolts, the installation position can be adjusted according to the actual space available.

[0046] In other embodiments, the base 140 may also be configured to be fixed to the support 101 by welding, or the base 140 may be part of the support 101.

[0047] In some embodiments, the column 150 is a height-adjustable column 150. The column 150 has a height adjustment function in the vertical direction, so that the camera box 160 has a large adjustment range in the height direction relative to the base 140, so as to better match the monitored component.

[0048] The method of making the column 150 height-adjustable is not limited. Optionally, the column 150 includes a first section and a second section with threaded connections, and raising and lowering are achieved through the helical threads of the threads. Optionally, the column 150 consists of a multi-section sleeve assembly, and different heights are adjusted by pins, spring buttons, or bolts.

[0049] In some embodiments, the column 150 and the base 140 are detachably connected. For example, the column 150 and the base 140 are threaded together. Alternatively, the column 150 and the base 140 are snap-fitted together. By detachably connecting the column 150 and the base 140, columns 150 of different heights can be adjusted and replaced as needed, especially when the base 140 and the support 101 are designed as a single unit.

[0050] In some embodiments, reference is made to Figure 5 The camera box 160 includes a box body 161 and an openable top cover 162. The box body 161 is provided with a camera mounting bracket 163. The front-facing camera 111, the left-facing camera 112 and the right-facing camera 113 are all mounted on the camera mounting bracket 163.

[0051] The housing 161 has an open-top receiving cavity. An openable top cover 162 is assembled to the housing 161 and is movable relative to the housing 161, allowing the housing 161 to be in an open or closed state. The openable top cover 162 protects the camera inside the housing from interference from water, dust, and other impurities in the surrounding environment. Optionally, one end of the openable top cover 162 is rotatably connected to the housing 161, and the other end is snap-fitted to the housing 161. Rotating the openable top cover 162 allows the housing 161 to switch between the open and closed states. Optionally, the openable top cover 162 is slidably connected to the housing 161. Sliding the top cover allows the housing 161 to switch between the open and closed states.

[0052] The front-facing camera 111, the left-facing camera 112, and the right-facing camera 113 are each mounted on a camera mount 163 inside the housing 161. The wall of the housing 161 has three through holes to expose the lenses of the three cameras respectively.

[0053] Furthermore, the position of the camera lens can be finely adjusted vertically or horizontally on the camera mount 163. For example, the camera mount 163 can be magnetically attached to the housing 161 to achieve the aforementioned adjustment. Alternatively, the camera mount 163 can be omnidirectionally connected to the housing 161 to achieve the same adjustment.

[0054] In some embodiments, reference is made to Figure 5The drip detection device 10 also includes a vibration isolator 170, which is located between the camera box 160 and the column 150, or between the column 150 and the base 140.

[0055] The specific form of the vibration isolator 170 is not limited. For example, the vibration isolator 170 can be a rubber vibration isolator, which utilizes the high damping characteristics of rubber to absorb vibration energy. As another example, the vibration isolator 170 can be a metal spring vibration isolator, which utilizes the elastic deformation of the metal spring to isolate vibration.

[0056] Vibration isolator 170 can reduce the shaking of the camera caused by vibration, thereby reducing the impact of the vibration of the monitored component on the monitoring screen and improving the clarity of the camera image.

[0057] Another aspect of this application is participation Figure 1 and Figure 2 Furthermore, a high-low pressure manifold system is proposed, comprising: a high-low pressure manifold skid 100, the high-low pressure manifold skid 100 including a support base 101, a high-pressure manifold assembly 102 disposed on the support base 101, and a low-pressure manifold assembly 103, wherein a stopcock valve 1021 is provided on a branch pipe of the high-pressure manifold assembly 102, and the stopcock valve 1021 is connected to a fracturing pump through a high-pressure pipeline 1022; and a high-low pressure manifold skid leak detection device 200, supported on the ground or the support base 101.

[0058] The high and low pressure manifold system may include multiple high and low pressure manifold skids 100, corresponding to multiple fracturing trucks. A suitable number of high and low pressure manifold skid leak detection devices 200 are installed according to the number of stopcock valves 1021 on each high and low pressure manifold skid 100 to ensure that each stopcock valve 1021 and its connected high pressure manifold can be monitored.

[0059] The drip detection device 10 is specifically adjustablely mounted on the support base 101 via its base 140. In the vertical direction, the axis of the forward-facing camera 111 is lower than the liquid flow height in the high-pressure pipeline 1022, and the axis of the left-facing camera 112 and the right-facing camera 113 is lower than the liquid flow height in the stopcock valve 1021, thereby better monitoring the liquid dripping status.

[0060] The high and low pressure manifold system of this application utilizes the high and low pressure manifold skid leak detection device 200, which can automatically identify leaks through image recognition technology and issue alarms to operators, thereby improving the timeliness of abnormal handling and reducing losses. In addition, the leak detection device 10 includes three cameras with different field of view, which can effectively monitor leaks in the stopcock valve 1021 and high pressure manifold, solving the problem of difficult monitoring caused by the large number of high pressure manifolds and mutual obstruction in the prior art.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
