Description

Technical Field

[0001] This utility model relates to the field of oil and gas extraction technology, and in particular to a system, device and well site for monitoring flare systems. Background Technology

[0002] Flare venting systems are crucial for the safe production of high-sulfur gas fields. During daily operation, the flare flame must be kept burning continuously, making the accuracy and timeliness of flame combustion monitoring paramount. Currently, thermocouples are commonly used for monitoring. In a flare venting system, thermocouples are installed at appropriate locations on the flare. When the flare burns, the heat of the flame raises the temperature of the thermocouple's measuring end, generating a thermoelectric potential. This thermoelectric potential signal is transmitted to the control system, which uses the magnitude of the thermoelectric potential to determine the flame temperature and thus whether the flare is burning normally. However, for oil and gas fields located in mountainous areas where the vented combustible gas contains high levels of hydrogen sulfide, the variable mountain climate and the highly corrosive nature of hydrogen sulfide gas make thermocouples extremely susceptible to damage.

[0003] Damage to thermocouples can lead to decreased thermocouple sensitivity, making it impossible to detect abnormal torch extinguishing in a timely manner, posing a production safety hazard. Furthermore, thermocouples can only collect temperature data, which is a single function. As the torch flame increases or decreases, the temperature change has a certain lag, and the thermocouple cannot detect the combustion status of the torch flame in a timely manner. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies in monitoring the flames of flares from oil and gas fields located in mountainous areas and where the flared combustible gas contains high levels of hydrogen sulfide. Due to the variable climate in mountainous areas and the strong corrosiveness of hydrogen sulfide gas, thermocouples are easily damaged, leading to a decrease in thermocouple sensitivity and an inability to detect abnormal flare extinction in a timely manner. This invention provides a system, device, and well site for monitoring the flame system of flares.

[0005] In a first aspect, the present invention provides a system for monitoring the flame of a flare torch, comprising: a visible light image acquisition module, a thermal imaging module, and an infrared monitoring module, wherein the visible light image acquisition module, the thermal imaging module, and the infrared monitoring module are respectively electrically connected to a terminal device;

[0006] The visible light image acquisition module includes a visible light camera unit for acquiring visible light images of the flame of the flare-up torch and a first information transmission unit for emitting the images acquired by the visible light camera unit. The visible light camera unit and the first information transmission unit are electrically connected.

[0007] The thermal imaging module includes a thermal imaging camera unit for acquiring thermal imaging images of the flame of the flare torch and a second information transmitting unit for transmitting the images acquired by the thermal imaging camera unit. The thermal imaging camera unit and the second information transmitting unit are electrically connected.

[0008] The infrared monitoring module includes an infrared camera unit for acquiring infrared images of the flame of the flare torch and a third information transmitting unit for transmitting the images acquired by the infrared camera unit. The infrared camera unit and the third information transmitting unit are electrically connected.

[0009] The visible light camera unit can be a megapixel camera, such as a lens of model DS-2CD7T45DWDV3-ISGL or model DS-2CD7U447MWD-XZ / JM, etc., and can capture images of the end of the torch combustion area, the gas pipeline, and the torch flame. The thermal imaging camera unit can be a thermal imaging camera of model DH-TPC-PT8641B or model HS56F-L49, and is used to capture thermal images of the torch flame combustion area. The infrared camera unit can be an infrared camera of model YJLH-101EX or model DS-2CE16D0T-IRPF, and is used to capture infrared images of the torch flame combustion area.

[0010] The first information transmitting unit, the second information transmitting unit, and the third information transmitting unit can be configured as digital wireless transmitters or wireless adapters, respectively.

[0011] By setting up a visible light camera unit and transmitting the images captured by the visible light camera unit to the display terminal through the first information transmission unit, the on-duty personnel can intuitively see the burning status of the torch flame and the status of the gas pipeline. By setting up a thermal imaging camera unit, images displaying the torch flame temperature can be captured, replacing the method of using thermocouples to detect the flame temperature. When the temperature of different areas of the flame changes, the images of the torch flame temperature captured by the thermal imaging camera unit will also change in real time, improving the sensitivity of flame temperature detection. Moreover, the thermal imaging camera unit can image in the dark or low light environment, is less affected by light conditions, and can better overcome the influence of weather such as fog and haze. Since the thermal imaging camera unit passively receives the light and heat information emitted by the flame to form an image, while the infrared camera unit actively emits infrared or ultraviolet rays of a preset band and receives these infrared or ultraviolet rays reflected back by the flame to display the flame temperature, the imaging effect of the infrared camera unit is less affected by changes in ambient temperature, mainly relying on the infrared or ultraviolet rays reflected by objects. Therefore, the images generated in environments with frequent temperature changes are more stable than those generated by the thermal imaging camera.

[0012] With the above settings, when the flare temperature changes, both the thermal imaging camera unit and the infrared camera unit can reflect the flame temperature changes in a timely manner. In foggy, low-light, or no-light environments, the thermal imaging camera unit can capture high-quality images. In environments with large temperature changes, the infrared camera unit can capture high-quality images. When the flame suddenly decreases or increases in size, the visible light camera unit can more intuitively and quickly reflect the flame's combustion state. By using the image information collected by the visible light image acquisition module, the thermal imaging module, and the infrared monitoring module to reflect the flame's combustion state, the system can adapt to different working conditions. This improves the timeliness of the system's monitoring of the flare flame's combustion state caused by interference from the working environment. Furthermore, the method of acquiring flame combustion state information does not involve direct contact with the flame, reducing the interference of the working environment on the system. This replaces the existing technology that uses thermocouples to monitor the flare flame, thus avoiding the phenomenon that thermocouples are easily damaged and their sensitivity decreases due to the variable climate in mountainous areas and the strong corrosiveness of hydrogen sulfide gas. This improves the system's adaptability to different working conditions and the sensitivity of flame state monitoring.

[0013] The system for monitoring the flame of the flare torch also includes a risk identification module, which includes a first information receiving unit, a decision-making unit, and a fourth information transmitting unit. The first information receiving unit can receive information transmitted by the first information transmitting unit, the second information transmitting unit, and the third information transmitting unit. The decision-making unit can generate preset information corresponding to the information received by the first information receiving unit. The fourth information transmitting unit is used to transmit the information generated by the decision-making unit.

[0014] The first information receiving unit can be configured as a wireless signal receiver or a wireless adapter, etc., and the fourth information transmitting unit can be configured as a digital wireless transmitter or a wireless adapter, etc.

[0015] The decision unit can be configured as an ACU7EVC core board or an ALINX ACU9EG core board, preferably an ACU7EVC core board. A model for analyzing the combustion hazards of torch flames can be integrated into the decision unit. The decision unit analyzes the combustion hazards of torch flames by receiving information from the first information receiving unit. The model for analyzing the combustion hazards of torch flames can be implemented using existing technologies, such as adjusting relevant parameters through image recognition algorithms. Specifically, patent CN109711345B discloses a technical solution that extracts texture feature images through filters, then extracts local binary features of the texture feature images based on local binary patterns, and uses an SVM classifier to identify the presence of flames based on the acquired local binary features. This involves extracting the effective area of ​​the image through continuous texture feature images and the extraction of local binary features, and performing dimensionality reduction of the feature vectors that require SVM classifier processing to identify the combustion status of the flames.

[0016] The information decision-making unit can be configured to generate different signal information representing various system states, such as system normal, system fault, and system stop, according to actual work needs.

[0017] The system for monitoring the flame of the flare torch also includes an alarm module, which includes a second information receiving unit and an indicator unit. The second information receiving unit is used to receive information sent by the fourth information transmitting unit, and the indicator unit can send a corresponding preset signal according to the information received by the second information receiving unit.

[0018] The alarm module sends an alarm signal through the indicator unit. The indicator unit can send sound signals and / or light signals and / or electromagnetic signals, etc. The second information receiving unit can be set as a wireless signal receiver or wireless adapter, etc. For example, when the second information receiving unit receives a signal representing a system fault, the indicator unit can send a preset message corresponding to a normal system signal.

[0019] The indicating unit may be one or more of a buzzer, an electromagnetic wave transmitter, and an indicator light.

[0020] Preferably, the indicator unit includes a sound alarm and a light alarm, wherein the sound alarm is a microphone and the light alarm includes a status indicator light and a laser light.

[0021] The microphone is a Vanguard V1 model, equipped with recording capabilities, capable of emitting a buzzing sound and recording ambient sound. The status indicator lights are NXD-211A miniature indicator lights, with a total of three: a first status indicator to indicate a general system fault, a second status indicator to indicate whether the system power is on, and a third status indicator to indicate a serious system fault. During normal system operation, the second status indicator lights up green; during a general system fault, the first status indicator lights up yellow; and during a serious system fault, the third status indicator lights up red. Two or three laser lights can be configured, with the color temperature set to natural light (3300K-5000K) according to work requirements. The illumination area can be set to 10-15 square meters, and the model can be SupFire G20, etc. In the event of a serious system fault, the laser lights will flash strongly as a warning, improving the system's alarm indication effect.

[0022] The system for monitoring the flame of the flare torch also includes an information exchange module, which is electrically connected to the visible light image acquisition module, the thermal imaging module, the infrared monitoring module, the risk identification module, and the terminal device. The information exchange module is used to enable the visible light image acquisition module, the thermal imaging module, the infrared monitoring module, and the risk identification module to interact with the terminal device.

[0023] This setting allows the system to interact with terminal devices, improving the timeliness of the system's flame monitoring and alarm response.

[0024] The information exchange module also includes an information storage unit.

[0025] This setting allows the working status of the torch flame to be recorded, facilitating the investigation of the cause of the accident in the event of a malfunction.

[0026] In a second aspect, the present invention provides a device for monitoring the flame of a flare, comprising a housing and a system for monitoring the flame of a flare, wherein the system for monitoring the flame of a flare is disposed within the housing.

[0027] This setting reduces the impact of environmental factors on the system and extends the system's lifespan.

[0028] The top surface of the shell is equipped with a protective canopy.

[0029] This setting reduces the interference of rain or strong light on the system, improving the device's anti-interference capability and accuracy.

[0030] The housing is rotatably connected to a support rod.

[0031] The support rod can be located at the bottom of the housing, with one end face of the support rod connected to the bottom surface of the housing, allowing the housing to rotate within the contact surface between the housing and the support rod; or one end of the support rod can be connected to the side surface of the housing, allowing the housing to rotate around the axis of the support rod.

[0032] This setting increases the flexibility of the device's use.

[0033] In a third aspect, this utility model provides a well site that employs the aforementioned device for monitoring the flame of a flare flare.

[0034] This setup improves the safety of production at the well site.
