[0002] In fields such as mineral exploration, hydrogeological surveys, and engineering disaster early warning, obtaining high-precision geological and environmental information from inside underground boreholes is crucial. Traditional monitoring methods mostly rely on downhole television for image acquisition, which can only provide visual images and cannot obtain quantitative rock stratum structure parameters. Another method is to infer the rock stratum attitude by manually measuring rock cores, which is not only inefficient and prone to subjective errors, but also fails to reflect the in-situ state of the rock strata.

[0003] In addition, although some downhole equipment with detection capabilities has emerged in related technologies, their functions are relatively limited. They can only record images or measure a certain type of physical or chemical field parameter. They lack a mechanism for simultaneous acquisition and deep fusion of multi-source data, making it difficult to calculate the rock formation occurrence in real time and accurately. They cannot achieve precise and efficient analysis and detection under complex geological conditions. Summary of the Invention

Furthermore, the embodiments of this application and the features in the embodiments can be combined with each other without conflict.

[0025] In fields such as mineral exploration, hydrogeological surveys, and engineering disaster early warning, obtaining high-precision geological and environmental information from inside underground boreholes is crucial. Traditional monitoring methods mostly rely on downhole television for image acquisition, which can only provide visual images and cannot obtain quantitative rock stratum structure parameters. Another method is to infer the rock stratum attitude by manually measuring rock cores, which is not only inefficient and prone to subjective errors, but also fails to reflect the in-situ state of the rock strata.

[0026] Furthermore, while some downhole equipment with detection capabilities has emerged in related technologies, their functions are relatively limited. They may only be able to record images or measure only a certain type of physical or chemical field parameter. They lack mechanisms for simultaneous acquisition and deep fusion of multi-source data, making it difficult to calculate rock formation attitude in real time and accurately. This hinders precise and efficient analysis and detection under complex geological conditions. Please refer to [reference needed]. Figures 1-3 This application provides an integrated monitoring device and system for downhole drilling, which integrates multiple modules to synchronously collect multi-dimensional information of downhole drilling, ensuring the accuracy and reliability of monitoring results.

[0027] Please refer to Figure 1 This is a functional block diagram of an integrated monitoring device for downhole drilling provided in an embodiment of this application. The integrated monitoring device integrates an image acquisition module, an attitude measurement module, a water flow detection module, a water quality detection module, a signal processing module, and an analysis and control module.

[0028] In this embodiment, the image acquisition module is preferably located at one end of the integrated monitoring device. During the monitoring process, the end with the image acquisition module is directly in contact with the downhole borehole to collect image data of the borehole wall and water environment in real time, providing a basis for the visualization of the geological conditions downhole.

[0029] Furthermore, an attitude measurement module is set up to detect the spatial attitude data of the integrated monitoring device in the borehole in real time, a water flow detection module detects the flow velocity and direction of the water flow in the borehole, and a water quality detection module detects the water quality parameters of the water body in the borehole, so as to realize the synchronous acquisition of multi-dimensional data.

[0030] Based on this, this application connects the signal processing module with the aforementioned image acquisition module, attitude measurement module, water flow detection module, water quality detection module, and analysis and control module to perform data fusion on the image data acquired by the image acquisition module, the spatial attitude data detected by the attitude measurement module, the flow velocity and direction of the water flow detected by the water flow detection module, and the water quality parameters detected by the water quality detection module. Then, the analysis and control module stores and visualizes the data processed by the signal processing module to provide an intuitive presentation of the complex downhole environment.

[0031] In an optional embodiment, please refer to Figure 2 This is a schematic diagram of the structure of an integrated monitoring device for downhole drilling provided in an embodiment of this application. The integrated monitoring device includes a first pipe section 10 and a second pipe section 11. A transparent spherical guide shroud 14 is provided at the end of the first pipe section 10 to house the image acquisition module. The spherical guide shroud 14 protects the image acquisition module inside the borehole, preventing the integrated monitoring device from rubbing against the borehole wall when it moves inside the borehole. At the same time, the transparent material can ensure the clarity of the image acquisition.

[0032] Preferably, the first pipe section 10 and the second pipe section 11 are made of high-strength corrosion-resistant materials, such as titanium, to withstand the complex and harsh physical and chemical environment downhole. The spherical guide shroud 14 is made of high-strength material to ensure that it is not easily broken when it comes into contact with rocks in the borehole, thereby effectively protecting the image acquisition module installed inside. The spherical guide shroud 14 should be sealed with the first pipe section 10 to prevent groundwater from seeping into the borehole and causing damage.

[0033] In an optional embodiment, hollow channels are provided in both the first pipe section 10 and the second pipe section 11. The wire harness can be integrated and passed through the hollow channels in the first pipe section 10 and the second pipe section 11, thereby optimizing the internal structural layout of the integrated monitoring device.

[0034] Furthermore, this application fixes the ends of the first pipe segment 10 and the second pipe segment 11 that are close to each other by at least three connecting ribs 12. That is, the end of the first pipe segment 10 away from the spherical guide shroud 14 is fixedly connected to the end of the second pipe segment 11 that is close to the spherical guide shroud 14 by at least three connecting ribs 12.

[0035] Preferably, the number of connecting ribs 12 is set to three, and the three connecting ribs 12 are evenly arranged between the first pipe section 10 and the second pipe section 11, thereby forming a hollow detection area 13 for water flow between the first pipe section 10 and the second pipe section 11.

[0036] In an optional embodiment, the connecting rib 12 is set as a high-strength steel cylinder. While achieving a stable connection between the first pipe segment 10 and the second pipe segment 11, it ensures that the wire passes through the connecting rib 12 of the cylindrical structure and enters the hollow channel inside the first pipe segment 10 and the second pipe segment 11, thus avoiding the wire harness being exposed to water and corroded, or affecting the water flow due to messy distribution.

[0037] Meanwhile, the three connecting ribs 12 are evenly placed between the first pipe section 10 and the second pipe section 11, which will not densely occupy the hollow detection area 13, ensuring that the water flow can pass smoothly through the hollow detection area 13.

[0038] As an optional implementation, the above-mentioned image acquisition device includes a camera disposed inside the spherical guide shroud 14, and an auxiliary lighting component integrated into the camera. The camera should cover at least 180 degrees of the plane corresponding to the spherical guide shroud 14, so that it can completely capture image data of the borehole inner wall and water environment without frequently adjusting the position of the camera.

[0039] On the other hand, the auxiliary lighting components are LED fill lights that support automatic dimming. The surround layout ensures that the light can cover the camera's shooting range. It automatically enhances the fill light in dark areas and reduces the brightness when there is sufficient light in shallow areas, ensuring that the camera can always capture high-definition images and adapt to different underground environments.

[0040] In an optional embodiment, the present application places an attitude measurement module at one end of the first pipe section 10 near the image acquisition module. The attitude measurement module includes at least a three-axis gyroscope, an accelerometer, and a magnetometer, thereby outputting the spatial attitude data of the integrated monitoring device in the borehole.

[0041] Specifically, this application sets the attitude measurement module close to the image acquisition module to minimize the physical distance between the two, reduce delays and interference during data transmission, and ensure that while the camera captures images of the borehole wall, the attitude measurement module can simultaneously acquire spatial attitude data at that moment. The output spatial attitude data should at least include the pitch angle, roll angle, and azimuth angle data of the integrated monitoring device in the borehole.

[0042] Furthermore, the signal processing module fuses the image data of the borehole wall and water environment acquired by the image acquisition module with the pitch angle, roll angle and azimuth angle data output by the attitude measurement module to accurately restore the angle and orientation of the integrated monitoring device during shooting, thereby calculating key information such as the tilt direction, dip angle and dip direction of the rock strata, and improving the accuracy and efficiency of downhole geological analysis.

[0043] It should be noted that the algorithms used for data fusion and rock strata information calculation can all be implemented based on existing algorithms. The signal processing module can use conventional multi-source data fusion algorithms such as Kalman filtering and weighted averaging to fuse image data and attitude data. The calculation of rock strata dip direction, dip angle and other information can be achieved through existing attitude calculation and coordinate transformation algorithms. Of course, other algorithms that can achieve data fusion and rock strata information calculation are also feasible, and this application does not impose any restrictions on them.

[0044] As an optional implementation, the water flow detection module provided in this application includes magnetic components disposed at the ends of the first pipe section 10 and the second pipe section 11, and miniature array electrodes disposed on the connecting rib 12.

[0045] Specifically, the aforementioned magnetic component includes a first magnet disposed on the first tube segment 10 near the hollow detection area 13, and a second magnet disposed on the second tube segment 11 near the hollow detection area 13. The first magnet and the second magnet are set to opposite polarities, thereby forming an induced magnetic field in the hollow detection area 13.

[0046] Furthermore, the aforementioned micro-array electrode serves as a core component, used to measure the induced electromotive force generated when water flows through the hollow detection area 13 and cuts the induced magnetic field, so as to calculate the flow velocity and direction of the water flow based on the induced electromotive force.

[0047] In this embodiment, since the conductive particles in the drilling water flow will cut the induced magnetic field formed between the first magnet and the second magnet during operation, based on the Faraday electromagnetic induction principle, the micro-array electrode can synchronously measure the generated induced electromotive force. The water flow velocity can be accurately calculated by parameters such as the magnitude of the electromotive force, the magnetic field strength and the distance between the electrodes. At the same time, the direction of water flow can be accurately determined by the change in the polarity of the electromotive force.

[0048] In an optional embodiment, the water quality detection module is located at one end of the first pipe section 10 or the second pipe section 11 near the hollow detection area 13. That is, the water quality detection module can be located at the top of the first pipe section 10 near the hollow detection area 13, or at the bottom of the second pipe section 11 near the hollow detection area 13.

[0049] Specifically, the water quality testing module includes a pH sensor, a turbidity sensor, and a conductivity electrode sensor. The detection probes of the pH sensor, turbidity sensor, and conductivity electrode sensor need to be placed in the hollow detection area 13 to accurately detect the acidity / alkalinity, suspended particulate matter concentration, and total dissolved solids (TDS) of the water passing through the hollow detection area 13.

[0050] In this embodiment, since the first pipe section 10 is close to the top of the hollow detection area 13 and the second pipe section 11 is close to the bottom of the hollow detection area 13, the detection probes of the pH sensor, turbidity sensor and conductivity electrode sensor are all located in the hollow detection area 13. Thus, when the water flows through the hollow detection area 13, the detection probes of each sensor are exposed in the flowing water, and the water quality parameters, as well as the water flow velocity and direction, are synchronously collected with the water flow detection module.

[0051] Understandably, pH sensors can monitor the acidity and alkalinity of water in real time, thus helping to assess the corrosion risk of well water. Turbidity sensors can indirectly help assess the leakage of rock fissures by identifying changes in suspended particulate matter concentration. Conductivity electrodes, by reflecting the total dissolved solids content, enable rapid screening of pollution anomalies. When TDS values ​​fluctuate significantly, it can be preliminarily determined that there may be pollutant intrusion or water quality anomalies in the water body, providing direction for subsequent precise investigation.

[0052] It should be noted that the first pipe section 10 and the second pipe section 11 should be strictly sealed. The connection points between the first pipe section 10 and the second pipe section 11 and the connecting rib 12, as well as the connection point between the first pipe section 10 and the spherical guide shroud 14, should be reinforced and sealed to prevent groundwater from seeping into the pipe section and causing equipment failure, and to ensure that the monitoring device can operate stably in the complex water environment of the well.

[0053] As an optional implementation, the signal processing module is also used to encode and compress the image data acquired by the image acquisition module in real time, send the compressed image data to the analysis and control module, then decode the compressed image data, and then fuse the decoded image data with the spatial attitude data detected by the attitude measurement module to construct a three-dimensional attitude model that displays the rock strata and fractures around the borehole.

[0054] Due to the limited bandwidth of transmission links in the downhole drilling environment, and the large data volume of image data, especially high-definition images, direct transmission can easily lead to problems such as lag and packet loss. Therefore, this application implements encoding and compression of image data to reduce the image data volume, and sends the compressed image data to the analysis and control module to ensure the stability and efficiency of data transmission.

[0055] Furthermore, the compressed image data is decoded by the analysis and control module. Since there are various interference signals in the borehole, the acquired image data and spatial attitude data are prone to noise. Therefore, the decoded image data and the spatial attitude data detected by the attitude measurement module need to be fused with noise reduction through an adaptive filtering algorithm to avoid interference signals affecting the accuracy of the data and to ensure the measurement accuracy and operational stability of the monitoring system.

[0056] It is understandable that the noise-reduced and fused data can be directly imported into conventional modeling software to obtain a three-dimensional attitude model for displaying the rock strata and fractures around the borehole. Furthermore, the conventional modeling software used here is a common general-purpose software used in the fields of geological exploration and downhole monitoring. The relevant operations are within the scope of conventional practice for those skilled in the art. Therefore, this application will not elaborate on the specific operation process of the modeling software.

[0057] In an optional embodiment, the analysis and control module is further configured to integrate the flow velocity and direction information acquired by the flow detection module into a flow vector field, and to superimpose and display the flow vector field on a three-dimensional orientation model; and to generate a trend graph of water quality parameters changing over time based on the water quality parameters detected by the water quality detection module.

[0058] Because current technologies often limit downhole monitoring to acquiring a single parameter, even if multiple parameters are acquired, there is no correlation between them, resulting in a fragmented and incomplete understanding of the borehole environment.

[0059] In this embodiment, the velocity and direction information obtained by the water flow detection module can be integrated into a water flow vector field, and then the water flow vector field can be superimposed on the three-dimensional orientation model for display, so that the water flow path and the borehole environment can be presented intuitively.

[0060] Based on this, the analysis and control module establishes a correlation between the water quality parameters detected by the water quality detection module and time. By using time as the horizontal axis and each water quality parameter as the vertical axis, a curve graph of water quality parameters changing over time is generated. This helps to detect abnormal changes in the water chemical environment in a timely manner and provides a basis for judging dynamic processes such as leakage and pollution.

[0061] As an optional implementation method, this device can be applied to fields such as mineral exploration, hydrogeological surveys, and early warning of engineering geological disasters.

[0062] For example, in the field of mineral exploration, it can accurately locate the extension direction of the ore body and potential enrichment areas. By monitoring the electromotive force generated by the groundwater cutting magnetic field, it can obtain the flow velocity and direction of fracture water in real time, providing early warning of water inrush risk for underground operations. The water quality detection module can provide a basis for accurately determining the boundary of the ore body by analyzing the abnormal mineralization reflected by the conductivity of the water body.

[0063] In the field of hydrogeological surveys, this device can penetrate turbid water bodies through a light-emitting camera, clearly identify lithological interfaces, accurately divide aquifers and impermeable layers, and track pollutants by tracing the spatial distribution and migration paths of water bodies with abnormal conductivity or pH values.

[0064] In the field of engineering geological disaster early warning, this device can capture sudden changes in rock strata occurrence caused by fault slippage, continuous increase in dip angle, or stress release. It can establish a correlation between these abnormal phenomena and changes in parameters such as water quality, flow velocity, and direction, and provide timely warnings for disasters such as landslides and mudslides, effectively ensuring construction safety.

[0065] As an optional implementation, the image acquisition module, attitude measurement module, water flow detection module, water quality detection module, signal processing module, and analysis and control module provided in this application are connected to each other via wired or wireless means.

[0066] Specifically, the wired connection can be implemented by using conductive connection to realize data and power transmission between modules, which is suitable for the connection stability requirements in the complex environment downhole. The wireless connection can choose Bluetooth, radio frequency and other commonly used wireless communication methods in this field, which do not require additional wiring, reduce the complexity of internal wiring of the device and are suitable for scenarios where modules are installed in a distributed manner.

[0067] It should be noted that this application does not impose further restrictions on the specific connection methods between the above modules, and those skilled in the art can flexibly choose according to the actual working conditions and installation requirements of the downhole drilling.

[0068] This application provides an integrated monitoring device for downhole drilling. An image acquisition module is located at the end of the device to accurately acquire image data of the borehole wall and the water environment. An attitude measurement module captures the spatial attitude data of the device in the borehole in real time. A water flow detection module and a water quality detection module respectively acquire the flow velocity and direction of the water and the water quality parameters. A signal processing module then performs centralized data fusion processing on the acquired image data, spatial attitude data, water flow parameters, and water quality parameters. An analysis and control module then stores and visualizes the fused data, avoiding the limitations of traditional single-parameter monitoring by establishing correlations between data from different dimensions for collaborative analysis. Simultaneously, the analysis and control module stores and visualizes the fused data, presenting the monitoring data intuitively through visualization, ensuring the stability and reliability of downhole drilling monitoring.
