Description

Technical Field

[0001] The present invention relates to the technical field of coal mine hydraulic fracturing monitoring and early warning technology, and in particular to a hydraulic fracturing monitoring and early warning device and a use method thereof. Background Art

[0002] Hydraulic fracturing (Hydraulic Fracturing) is widely used in the extraction of oil, natural gas, and shale gas, particularly in oil and gas exploration under complex geological conditions. Hydraulic fracturing injects high-pressure fluid into underground rock formations, promoting the formation of cracks and increasing oil and gas mobility, thereby improving extraction efficiency. However, potential risks during the hydraulic fracturing process, such as pressure fluctuations, fluid leakage, and equipment failure, pose challenges to the safety and profitability of operations. Therefore, accurate real-time monitoring and early warning systems are particularly important.

[0003] Existing hydraulic fracturing monitoring methods mostly rely on manual or simple pressure monitoring methods, which are unable to fully and real-timely monitor various parameters during the operation. These traditional systems typically only provide single pressure data and lack comprehensive monitoring of other key factors such as flow rate, sediment content, and temperature. The real-time and accuracy of the monitoring data often fail to meet actual needs. Furthermore, traditional monitoring systems often have blind spots in monitoring when faced with complex geological environments and dynamically changing operating conditions, making it impossible to effectively identify equipment failures or anomalies, making it difficult to respond to emergencies in a timely manner and posing risks to safety management and environmental protection.

[0004] With the continuous advancement of fracturing technology, especially the increase in depth and complexity of operations, the limitations of existing monitoring technologies are becoming increasingly prominent. For example, in deep-well hydraulic fracturing, due to the high formation pressure, traditional pressure sensors are prone to failure or slow response. Furthermore, in multi-stage fracturing operations, the dynamic changes in the injected fluid type, flow rate, and composition also affect the equipment and operation results. Traditional monitoring methods are unable to fully capture these changes, which can easily lead to misjudgments.

[0005] Therefore, there is an urgent need for a new hydraulic fracturing monitoring and early warning device that can monitor multiple key parameters (such as pressure, flow rate, and sediment content) in real time during operations and provide early warning of abnormal conditions through an intelligent analysis system. This device not only provides timely alarms for emergencies such as leaks and excessive pressure, but also optimizes the efficiency and safety of hydraulic fracturing operations through precise pressure and flow control, reducing the risk of equipment damage and environmental pollution. Summary of the Invention

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

[0012] Furthermore, the control panel includes a data processing module, which is used to receive data collected by the pressure sensor and compare it with a preset standard value to trigger an automatic alarm and control the action of the electric butterfly valve.

[0013] Furthermore, it also includes a shell, which is fixed on the outside of the monitoring tube. The shell is provided with an inspection port, which penetrates into the interior of the monitoring tube; a detachable filling block is provided in the inspection port, and the outside of the inspection port is sealed by a cover.

[0014] Furthermore, a mounting ring is provided at one end of the shell away from the monitoring tube, and the sealing cover is mounted on the mounting ring by multiple sets of fixing bolts.

[0015] Furthermore, a slot is provided at one end of the shell away from the monitoring tube, a sealing ring is provided in the slot, and the sealing cover and the shell are sealed by the sealing ring.

[0016] Furthermore, the ends of the liquid outlet pipe and the liquid inlet pipe away from the monitoring pipe are both provided with connecting flanges.

[0017] Furthermore, the connecting flange is evenly distributed with multiple groups of mounting holes for connecting the monitoring pipe to the hydraulic fracturing system.

[0018] Furthermore, a plurality of fixing rods are provided on the outer side of the mounting frame, and the mounting frame is fixedly connected to the inside of the monitoring tube via the fixing rods.

[0019] Furthermore, the liquid outlet pipe and the liquid inlet pipe are respectively connected to the two ends of the monitoring pipe by welding; the monitoring cover is connected to the limit rod by welding.

[0026] (6) Regularly check the working status of the device and perform maintenance on the equipment to ensure stable operation of the system.

[0027] Furthermore, during equipment maintenance, the pressure sensor or monitoring cover can be replaced or calibrated through the inspection port of the shell.

[0028] The beneficial effects of the present invention are:

[0029] The present invention provides a hydraulic fracturing monitoring and early warning device and its use method, which has significant technical advantages and practical application value compared with the existing technology, which is specifically reflected in the following aspects:

[0030] 1. Real-time monitoring of multiple parameters to improve operation control capabilities

[0031] The present invention integrates a high-precision pressure sensor and a monitoring cover structure to monitor the pressure changes of the fracturing fluid during hydraulic fracturing in real time, and combines it with the data processing module of the control panel to achieve comprehensive monitoring of key parameters such as flow rate and sediment content. Compared with the limitation of traditional monitoring systems that can only provide a single pressure data, the present invention can fully capture the dynamic changes during the operation and provide operators with accurate and real-time feedback on the operation status. This not only helps to quickly discover potential problems (such as abnormal pressure or sediment blockage), but also significantly improves the ability to control fracturing operations under complex geological conditions, ensuring the smooth progress of operations.

[0032] 2. Intelligent early warning and adaptive control to enhance safety and efficiency

[0033] The device is equipped with an intelligent control panel and data processing module, which compares data collected by the pressure sensor with preset standard values ​​in real time. If the monitored value exceeds the safe range, the system automatically triggers an alarm and quickly shuts off the flow of fracturing fluid via an electrically connected electric butterfly valve, effectively preventing risks such as pipeline blockage and equipment overpressure. Furthermore, the system automatically adjusts the flow rate or composition of the fracturing fluid based on real-time data, achieving adaptive control. This intelligent early warning and control function significantly reduces the possibility of human error, significantly improving operational safety and efficiency, and reducing equipment damage and production interruptions caused by emergencies.

[0034] 3. Modular design for easy maintenance and long-term use

[0035] The present invention utilizes a detachable connection design. For example, the pressure sensor is connected to the mounting bracket via mounting bolts, and the monitoring cover is clipped onto the pressure sensor via a slot, greatly facilitating equipment maintenance and component replacement. Furthermore, the access port and removable filler block structure provided on the housing further simplify internal inspection and maintenance operations. The cover and housing are securely sealed using fixing bolts and a sealing ring, ensuring the stability and durability of the device in harsh environments such as high pressure and high sediment levels. These designs not only reduce maintenance costs but also extend the service life of the device, adapting it to long-term, complex operating conditions.

[0036] 4. Environmental and safety assurance to reduce potential risks

[0037] By precisely monitoring parameters such as fracturing fluid pressure and sediment content, the present invention provides timely warnings when fluid leaks or abnormal pressures occur, preventing environmental pollution or safety incidents caused by untimely problem detection. For example, the rapid response of the electric butterfly valve can effectively prevent the continued injection of abnormal fluids, reducing potential threats to groundwater resources or the surrounding environment. Furthermore, the device's stability and intelligent control capabilities reduce the probability of equipment failure, further ensuring the safety of operators.

[0038] 5. Adapt to complex working conditions and improve economic benefits

[0039] The structural design and functional configuration of this invention adapt to the operational requirements of deep wells and multi-stage fracturing in complex geological environments. The welded connections between the outlet and inlet pipes, as well as the monitoring cover and stopper rod, ensure the stability of the device in high-pressure, high-impact environments. The sliding fit between the fixed rod and stopper hole enhances the accuracy and reliability of the monitoring assembly. These features enable the device to operate stably under a variety of operating conditions, significantly improving the economic benefits of hydraulic fracturing operations by optimizing operating parameters and reducing downtime.

[0040] In summary, the present invention comprehensively improves the safety, efficiency, and economy of hydraulic fracturing operations through real-time multi-parameter monitoring, intelligent early warning and regulation, modular maintenance design, and highly adaptable structure, while effectively reducing environmental risks. It is suitable for complex working conditions in fields such as oil, natural gas, and shale gas extraction, and has broad application prospects and promotion value.

[0050] Example 1

[0051] like Figures 1 to 3 As shown, this embodiment provides a hydraulic fracturing monitoring and early warning device for real-time monitoring and early warning during the extraction of oil, natural gas, and shale gas. The device includes a monitoring tube 1, a monitoring assembly, and a housing 3. The specific structure is as follows:

[0052] The monitoring tube 1 is the core component of the device, which is used to guide the flow of fracturing fluid and carry the monitoring components. A liquid outlet pipe 101 is provided at one end of the monitoring tube 1, and a liquid inlet pipe 102 is provided at the other end. The two are fixedly connected to the two ends of the monitoring tube 1 by welding, ensuring the sealing and high-pressure resistance of the connection. The liquid outlet pipe 101 and the liquid inlet pipe 102 are both provided with a connecting flange 103 at the end away from the monitoring tube 1. There are multiple groups of mounting holes evenly distributed on the connecting flange 103. The monitoring tube 1 is connected to the liquid flow channel of the hydraulic fracturing system by bolts to ensure stable docking between the device and the system. An electric butterfly valve 205 is installed inside the liquid outlet pipe 101 to control the circulation and blocking of the fracturing fluid. The electric butterfly valve 205 is electrically connected to the control panel on the outside of the monitoring tube 1 through wires, and can be automatically opened and closed.

[0053] The monitoring assembly includes a mounting frame 2, a pressure sensor 201, and a monitoring cover 202. The mounting frame 2 is fixedly mounted inside the monitoring tube 1 and is used to mount and support the monitoring components. Several sets of fixing rods are provided on the outside of the mounting frame 2, which are fixedly connected to the inner wall of the monitoring tube 1 through the fixing rods to ensure the stability of the mounting frame 2 under the impact of high-pressure fluid. Multiple sets of limiting holes 203 are evenly distributed on the mounting frame 2. Limiting rods 204 are provided in the limiting holes 203 to slide with them. The limiting rods 204 can slide axially along the limiting holes 203 to provide stable guidance. The monitoring cover 202 is located at one end of the mounting frame 2 near the liquid inlet pipe 102 and is fixed to the limiting rods 204 by welding, ensuring the stability of the monitoring cover 202 under the impact of fracturing fluid. The pressure sensor 201 is located between the monitoring cover 202 and the mounting frame 2. One end of the pressure sensor is fixed to the mounting frame 2 by mounting bolts, and the other end is removably connected to the monitoring cover 202 through a slot inside the monitoring cover 202. After the fracturing fluid enters the monitoring pipe 1 through the liquid inlet pipe 102 , it contacts the monitoring cover 202 and applies pressure to the pressure sensor 201 , thereby achieving real-time monitoring of the fracturing fluid pressure change.

[0054] The shell 3 is fixedly mounted on the outside of the monitoring tube 1 to protect the internal components and facilitate maintenance. The shell 3 is provided with an inspection port that extends into the interior of the monitoring tube 1, facilitating inspection and repair of the internal components. A removable filling block 303 is provided in the inspection port to fill the space inside the shell 3 and maintain the integrity of the inner wall of the monitoring tube 1. The outside of the inspection port is sealed by a cover 302. A mounting ring 301 is provided at the end of the shell 3 away from the monitoring tube 1. The cover 302 is fixed to the mounting ring 301 by multiple sets of fixing bolts 304 and fixing nuts 305. A slot and a sealing ring are provided between the shell 3 and the cover 302 to ensure a good sealing effect and prevent liquid leakage in a high-pressure environment. A threaded hole is provided inside the fixing nut 305 to match the fixing bolt 304. Both the mounting ring 301 and the cover 302 are provided with fixing holes to facilitate the disassembly and assembly of the fixing bolt 304, simplifying the maintenance process.

[0055] A control panel is located outside the monitoring tube 1, electrically connected to the pressure sensor 201 and the electric butterfly valve 205 via wires. The control panel houses a data processing module that receives pressure data collected by the pressure sensor 201 and compares it in real time with preset standard values. If the monitored value exceeds a preset range, the data processing module triggers an automatic system alarm and sends a signal to the electric butterfly valve 205, causing it to close quickly to avoid risks such as pipeline blockage and equipment overpressure. The control panel can also adjust the flow rate or composition of the fracturing fluid based on real-time data, achieving adaptive control.

[0056] When using the hydraulic fracturing monitoring and early warning device of the present invention, the specific operating steps are as follows:

[0057] 1. Install the device in the hydraulic fracturing system. Use bolts to securely connect the monitoring tube 1 to the system's liquid flow channel through the mounting holes on the connecting flange 103, ensuring a secure and sealed connection.

[0058] 2. Connect the power supply and start the device, inject fracturing fluid through the liquid inlet pipe 102, so that the fracturing fluid contacts the monitoring cover 202;

[0059] 3. The pressure sensor 201 monitors the pressure changes on the monitoring cover 202 in real time, records the dynamic data of the fracturing fluid, and detects parameters such as sediment content;

[0060] 4. The data processing module of the control panel compares the pressure value collected by the pressure sensor 201 with the preset standard value. When the monitored value exceeds the safety range, the system is triggered to emit an audible and visual alarm;

[0061] 5. After receiving the alarm signal, the system automatically controls the electric butterfly valve 205 to close, blocking the flow of fracturing fluid to avoid pipeline blockage or equipment damage, and at the same time adjusts the flow rate or composition of the fracturing fluid as needed;

[0062] 6. Regularly check the working status of the device through the inspection port of the housing 3 and perform maintenance on components such as the pressure sensor 201 and the monitoring cover 202 to ensure long-term stable operation of the system;

[0063] 7. During maintenance, the pressure sensor 201 or the monitoring cover 202 can be replaced or calibrated by removing the fixing bolts 304 and the fixing nuts 305, opening the cover 302, and taking out the filling block 303.

[0064] This invention integrates high-precision pressure sensors, monitoring covers, and intelligent control systems to achieve real-time monitoring of pressure and other parameters during hydraulic fracturing. Combined with automatic alarms and the rapid response of electric butterfly valves, it effectively improves operational safety and efficiency. The device's modular design and access ports facilitate maintenance, while welded connections and sealing rings enhance its stability in high-pressure, high-impact environments. It is suitable for oil, natural gas, and shale gas extraction under complex conditions such as deep wells and multi-stage fracturing, demonstrating significant application value and promising prospects.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions, which should all be included in the scope of the claims of the present invention.
