Description

Technical Field

[0001] The present invention belongs to the technical field of geophysical survey, and in particular relates to a geophysical survey system and method. Background Art

[0002] Geophysical exploration, also known as geophysical exploration, refers to the detection of geological conditions such as stratum lithology and geological structure by studying and observing the changes in various geophysical fields. Since different rock media that make up the earth's crust often have differences in density, elasticity, conductivity, magnetism, radioactivity, and thermal conductivity, these differences will cause local changes in the corresponding geophysical fields. By measuring the distribution and change characteristics of these physical fields and combining them with known geological data for analysis and research, the purpose of inferring geological characteristics can be achieved.

[0003] Existing geophysical exploration methods encounter some limitations when evaluating underground structures and environmental conditions, which may lead to inaccurate survey data. For example, gravity exploration and magnetic exploration may be affected by terrain correction errors and non-uniqueness of inversion results, which will lead to a decrease in the quality of survey data. The vertical resolution of seismic exploration decreases when exploring deep layers, and the resolution of electrical exploration (including electromagnetic exploration) also decreases rapidly with the increase of exploration depth. Ground penetrating radar needs to be used in conjunction with other methods to improve detection accuracy, while microseismic exploration needs to be combined with other geophysical methods to enhance the ability to interpret geological structures. The limitations of these methods mean that if they are not properly identified and corrected, they will lead to incorrect interpretation of underground structures and incorrect assessments of underground environmental conditions, which will in turn affect the accuracy of exploration decisions.

[0054] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0055] like Figure 1As shown, a geophysical survey system includes an electromagnetic exploration constraint signal acquisition module, an exploration correction factor determination module, an exploration characteristic factor acquisition module and a characteristic factor transmission process judgment module.

[0056] The electromagnetic exploration constraint signal acquisition module is used to analyze the geophysical electromagnetic exploration characteristics and obtain the geophysical electromagnetic exploration characteristic constraint signal.

[0057] The analysis process is as follows: obtaining geophysical electromagnetic exploration characteristic data, including exploration conductivity, exploration magnetic susceptibility, and exploration electromagnetic wave attenuation rate; based on the acquired geophysical electromagnetic exploration characteristic data, comprehensive analysis is performed to obtain geophysical electromagnetic exploration characteristic constraint signals. , expressed as;

[0058] ;

[0059] Where dd is the exploration conductivity, ch is the exploration magnetic susceptibility, sj is the exploration electromagnetic wave attenuation rate, , , are the compensation factors of dd, ch, and sj respectively, e is a natural constant; lg is a logarithmic function, which means the logarithm with base 10; It serves as the analytical basis for obtaining characteristic factors of geophysical electromagnetic exploration.

[0060] Exploration conductivity, magnetic susceptibility and electromagnetic wave attenuation rate are important electromagnetic characteristic parameters of underground materials, which help to more accurately distinguish different underground materials during electromagnetic exploration. Conductivity can help identify the conductivity of rock formations, magnetic susceptibility is used to identify magnetic minerals or rock formations, and electromagnetic wave attenuation rate reflects the absorption and reflection characteristics of geological bodies to electromagnetic waves. By calculating these constraint signals, the characteristics of different geological bodies can be effectively identified, the material distinction can be improved, and misjudgment can be reduced.

[0061] In geophysical exploration, conductivity, magnetic susceptibility and electromagnetic wave attenuation rate are used as constraint signals to effectively reduce the impact of external interference on exploration results. For example, areas with higher conductivity may experience more electromagnetic wave attenuation. This relationship helps to extract more accurate underground structure information from exploration data. By analyzing these signals, the accuracy of exploration can be effectively improved and exploration errors can be reduced.

[0062] Each formula is normalized as needed during calculation. The set compensation factor is obtained from the database, and a mapping set of each historical measured data and the corresponding compensation factor is established based on the historical data to obtain the compensation factor corresponding to the current data.

[0063] Electrical conductivity is a physical quantity that measures the ability of a material to conduct electricity, and reflects the ability of a stratum or rock to conduct electric current. In geophysical exploration, electrical conductivity helps determine the type of underground materials, water content, salt content, and distribution of other conductive minerals. Electrical conductivity is usually measured by electromagnetic exploration equipment, such as resistivity instruments and induced polarization (IP) equipment. Magnetic susceptibility is a physical quantity that measures the degree of magnetization of a material under the action of an external magnetic field. It provides information about the content and distribution of magnetic minerals (such as magnetite) in rocks or soils, and is often used to identify different geological structures and mineralized areas. Magnetic susceptibility is usually measured using a magnetometer or susceptibility meter. The electromagnetic wave attenuation rate refers to the rate at which the intensity of an electromagnetic wave decreases when it propagates in a medium, which can reflect the electromagnetic properties of the medium, such as electrical conductivity and dielectric constant. A high attenuation rate means that the medium absorbs electromagnetic waves more strongly, which is usually related to high conductivity or high water content. The electromagnetic wave attenuation rate is usually measured by ground penetrating radar (GPR), induced polarization instruments, or other electromagnetic exploration equipment.

[0064] Conductivity, magnetic susceptibility, and electromagnetic wave attenuation rate each reflect different physical properties of the underground medium. Combining these parameters can provide a more comprehensive view of the underground structure, thereby enhancing the ability to interpret geological structures and geological changes. Different types of resources will show different electromagnetic characteristics. This information can be used to determine the type and quality of resources. Through detailed electromagnetic characteristic analysis, complex underground conditions can be predicted, and electromagnetic characteristic data provides valuable measured data for earth science research.

[0065] The exploration correction factor determination module is used to collect the correction influence data of the geophysical electromagnetic exploration process, analyze the correction influence data of the geophysical electromagnetic exploration process, and determine the correction factor of the geophysical electromagnetic exploration process.

[0066] The exploration correction factor determination module includes a correction noise data analysis unit, a correction environment data analysis unit, a correction geological data analysis unit, and a geophysical electromagnetic exploration correction factor acquisition unit;

[0067] A modified noise data analysis unit is used to collect and analyze noise data during geophysical electromagnetic exploration to obtain noise constraint factors;

[0068] A modified environmental data analysis unit is used to collect and analyze geophysical electromagnetic exploration environmental data to obtain environmental constraint factors;

[0069] Modified geological data analysis unit, used to collect and analyze geophysical electromagnetic exploration geological data to obtain geological constraint factors;

[0070] The geophysical electromagnetic exploration correction factor acquisition unit is used to determine the geophysical electromagnetic exploration process correction factor based on the noise constraint factor, the environmental constraint factor and the geological constraint factor.

[0071] By analyzing the noisy data during the exploration process and applying noise constraint factors, the background noise and interference in the data can be effectively reduced, so that geological signals can be clearly identified. Environmental data analysis can help identify and correct variations caused by environmental factors such as climate change, surface water, and vegetation, ensuring that the data reflects the true physical state of the underground. The geological constraint factors obtained by detailed analysis of geological data can more accurately interpret the distribution of underground structures and materials, especially in complex geological environments. The combined use of these correction factors can better understand geological risks. Through automated data analysis and correction processes, large amounts of data can be processed in a shorter time, improving the overall efficiency of exploration projects.

[0072] Acquire noise data of the geophysical electromagnetic exploration process, including ambient noise signal strength, signal-to-noise ratio, and magnetic storm index; based on the acquired noise data of the geophysical electromagnetic exploration process, conduct a comprehensive analysis to obtain the noise constraint factor, which serves as the analysis basis for determining the correction factor of the geophysical electromagnetic exploration process.

[0073] Environmental noise signal strength refers to the intensity of background noise captured by geophysical exploration equipment. These noises may come from natural sources (such as wind, rain, lightning) or man-made sources (such as traffic, industrial activities). High noise signal strength means high background noise levels, which may mask or interfere with underground geological signals. Environmental noise is usually monitored by geophysical instruments such as seismometers, geoelectric instruments or electromagnetic induction devices. Signal-to-noise ratio is a measure of the ratio of effective signal strength to background noise strength. A high signal-to-noise ratio means that the effective signal is significantly stronger than the noise, which usually means good data quality, clear and reliable signals, based on magnetometer acquisition. The magnetic storm index is used to assess the intensity of geomagnetic activity, especially geomagnetic storms caused by solar activity. Geomagnetic storms affect the Earth's magnetic field, which in turn affects the quality of electromagnetic exploration data. Understanding the magnetic storm index is crucial to predicting and mitigating these effects. The magnetic storm index is usually obtained through data provided by geomagnetic monitoring stations or global magnetic storm monitoring networks (such as NOAA's Space Weather Prediction Center).

[0074] By accurately measuring and analyzing noise data, noise constraint factors can help identify and remove noise components in detection data, thereby clearly revealing the true signal of geological structure. The data after noise removal is purer, making geological interpretation more accurate and reducing the risk of misunderstanding or missing key geological features. Through effective noise management, the quality of data acquired initially is higher, reducing repeated exploration activities due to data quality issues. Applying noise constraint factors in the data acquisition stage can reduce the burden of later data processing and speed up the entire exploration process. In electromagnetic exploration, environmental factors such as magnetic storms and other electromagnetic interference have a great impact on data quality. By applying noise constraint factors, the impact of these environmental changes can be more effectively adapted and adjusted.

[0075] The noise constraint factor is obtained as follows:

[0076] ;

[0077] In the formula, is the noise constraint factor, zs is the environmental noise signal strength, xzb is the signal-to-noise ratio, cb is the magnetic storm index, , , They are the compensation factors of the set zs, xzb, and cb respectively.

[0078] Noise interference can affect the reliability of data. By calculating the ambient noise signal strength and signal-to-noise ratio, the clarity and accuracy of the signal can be evaluated to ensure that the signal quality is not adversely affected during data transmission, thereby improving the accuracy and availability of the data. In geological exploration, environmental monitoring, and other scientific measurements, noise can affect the quality of measurement results. For example, in electromagnetic exploration, external noise may interfere with the measured electromagnetic signal. By analyzing the signal-to-noise ratio and ambient noise signal strength, appropriate instruments, techniques, and processing methods can be selected to reduce the interference of noise on the measurement results, thereby improving exploration accuracy and enhancing the robustness of data processing and analysis.

[0079] Obtain geophysical electromagnetic exploration environmental data, including ambient temperature, ambient groundwater level, and ambient soil conductivity; based on the acquired geophysical electromagnetic exploration environmental data, conduct a comprehensive analysis to obtain environmental constraint factors, which serve as the analysis basis for determining the correction factors for the geophysical electromagnetic exploration process.

[0080] Ambient temperature refers to the air temperature in the exploration area. Temperature affects the performance of geophysical measurement equipment and the physical properties of underground materials, such as the thermal conductivity of rocks and the moisture content of soil. Ambient temperature is usually obtained through thermometers or more advanced weather station equipment. Changes in groundwater levels can significantly affect the conductivity of geological structures. Groundwater levels are usually measured by water level gauges or pressure sensors. Soil conductivity is a measure of the ability of soil to conduct electricity, which affects the response of geological electromagnetic measurements. Soil conductivity is usually measured by soil conductivity meters.

[0081] Temperature changes affect the performance of geophysical instruments and the stability of measurement data. By accounting for temperature factors, these effects can be corrected, resulting in more accurate measurements. Water level changes affect the conductivity of the subsurface medium, especially when performing electromagnetic surveys. Accounting for the effect of water level changes on electromagnetic properties can improve the accuracy of the interpretation of subsurface structures. Soil conductivity directly affects the response of geoelectric and electromagnetic methods. By correcting for changes in soil conductivity, subsurface resources and structures can be more accurately assessed. Environmental constraints allow geophysical surveys to be optimized under different environmental conditions, adjusting measurement strategies and techniques to specific site conditions, such as adjusting transmit power or receiver sensitivity to cope with high conductivity soils or changing water level conditions. By identifying and correcting for potential errors caused by environmental variables, the uncertainty and complexity that needs to be faced in data processing is reduced. This preprocessing can simplify the data interpretation process and reduce the possibility of misjudgments caused by neglecting environmental factors.

[0082] The environmental constraint factor is obtained as follows:

[0083] ;

[0084] In the formula, is the environmental constraint factor, wd is the ambient temperature, ds is the ambient groundwater level, td is the ambient soil conductivity, , , They are the compensation factors of the set wd, ds, and td respectively.

[0085] Ambient temperature, groundwater level and soil conductivity are important factors that affect the safety and stability of underground projects (such as tunnels, mines, underground buildings, etc.). By calculating and analyzing these environmental factors, potential risks can be predicted in advance, and preventive measures can be taken to ensure the safety of underground projects. Changes in ambient temperature and groundwater level may affect the stability of the ore body, the efficiency of oil and gas extraction, the flow path of groundwater, etc. By analyzing these factors, strategies for resource exploration and development can be optimized, and the success rate and efficiency of resource extraction can be improved.

[0086] Obtain geophysical electromagnetic exploration geological data, including formation dip, vertical thickness of geological layers, and rock density; based on the acquired geophysical electromagnetic exploration geological data, conduct a comprehensive analysis to obtain geological constraint factors, which serve as the analytical basis for determining correction factors for the geophysical electromagnetic exploration process.

[0087] Dip angle refers to the inclination angle of a geological layer relative to the horizontal plane. This angle can indicate the placement direction of the stratum and is a key parameter for interpreting tectonic activity and geological history. Dip angle is usually obtained through a geological compass or inclinometer. Vertical thickness of a geological layer refers to the actual thickness of a geological layer in the vertical direction, which has nothing to do with the drilling direction during measurement. Vertical thickness is usually calculated by combining drilling data with dip angle data. Rock density refers to the mass of rock per unit volume, reflecting the mineral composition and porosity of the rock. Rock density is usually obtained by laboratory measurement of core samples.

[0088] Geological constraint factors can help build more accurate geological models, taking into account factors such as formation dip, thickness and rock density in detail, which is essential for accurately predicting the distribution of underground resources such as minerals, oil and gas. Through detailed analysis of geological data, errors that may be encountered in geophysical measurements can be identified and corrected, such as data deviations caused by equipment settings or environmental factors. Accurate geological data analysis helps to assess potential geological risks and is particularly beneficial for exploration activities in complex geological environments. The use of geological constraint factors enables exploration technology to adapt to changing geological conditions and improve the success rate of exploration.

[0089] The geological constraint factors are obtained as follows:

[0090] ;

[0091] In the formula, is the geological constraint factor, qj is the formation dip, hd is the vertical thickness of the geological layer, md is the rock density, , , are the compensation factors of the set qj, hd, and md respectively.

[0092] By calculating geological constraint factors such as stratum dip, vertical thickness of geological layers and rock density, underground geological models can be constructed more accurately. These parameters help describe the morphology, distribution and properties of underground rock formations, so that geological models can better reflect actual geological conditions and reduce prediction errors. The dip, thickness and rock density of strata are important parameters for assessing mineral resource reserves and groundwater reserves. By calculating these constraint factors, the reserves of underground resources can be estimated more accurately, avoiding over- or underestimation, thereby providing a scientific basis for resource mining or development. In geological exploration, the collected geophysical data such as seismic, magnetic, resistivity, etc. need to be interpreted. The calculation of geological constraint factors can provide important background information and contribute to the accurate interpretation of geophysical data.

[0093] The noise constraint factor, environmental constraint factor and geological constraint factor are stored as designated tags, and the designated tags are compared with the set tags stored in the database to obtain the set tags corresponding to the designated tags, and obtain the geophysical electromagnetic exploration process correction factors corresponding to the set tags stored in the database.

[0094] By labeling key parameters, the data management process can be systematized and standardized. This approach helps maintain consistency in data structure, making data retrieval, comparison and application more efficient and accurate. By comparing tags, appropriate correction factors can be quickly located and applied without manual search or recalculation, significantly improving the speed and efficiency of data processing. Correction factors are obtained based on exactly matched tags, ensuring the relevance and accuracy of correction measures, thereby improving the quality of exploration data. Different exploration environments and conditions can be configured with corresponding correction factors, so that data processing can maintain a high level of adaptability and accuracy in different situations.

[0095] The exploration characteristic factor acquisition module is used to correct the geophysical electromagnetic exploration characteristic constraint signal based on the geophysical electromagnetic exploration process correction factor to obtain the geophysical electromagnetic exploration characteristic factor.

[0096] The analysis process is as follows: the geophysical electromagnetic exploration process correction factor and the geophysical electromagnetic exploration characteristic constraint signal are introduced into the geophysical electromagnetic exploration signal correction model to obtain the geophysical electromagnetic exploration characteristic factor , expressed as;

[0097] ;

[0098] In the formula, Correction factor for geophysical electromagnetic exploration process.

[0099] By combining correction factors and constraint signals, the original exploration data can be accurately adjusted to eliminate errors caused by other factors. This correction makes the final characteristic factors more accurately reflect the actual geological structure underground. The corrected data provides a clearer geological view, helping geologists to analyze the stratigraphic structure, rock type and geological changes more deeply, which is especially important for complex or subtle geological structures. The signal correction model automatically processes the input constraint signals and correction factors, which improves the speed and efficiency of data processing and reduces the possibility of human error.

[0100] The characteristic factor transmission process judgment module is used to transmit the geophysical electromagnetic exploration characteristic factors to the data center, analyze the geophysical electromagnetic exploration characteristic factor transmission process, and judge whether the geophysical electromagnetic exploration characteristic factor transmission is successful: if the geophysical electromagnetic exploration characteristic factor transmission is successful, a transmission success notification is issued; if the geophysical electromagnetic exploration characteristic factor transmission is unsuccessful, a retransmission instruction is issued.

[0101] like Figure 2 As shown, the analysis process is:

[0102] Acquire the transmission process data of geophysical electromagnetic exploration characteristic factors, including the transmission delay of geophysical electromagnetic exploration characteristic factors, the transmission signal strength of geophysical electromagnetic exploration characteristic factors, and the transmission packet loss rate of geophysical electromagnetic exploration characteristic factors;

[0103] Based on the acquired geophysical electromagnetic exploration characteristic factor transmission process data, the transmission process analysis factor is obtained through comprehensive analysis. The transmission process analysis factor serves as the analysis basis for judging whether the transmission of geophysical electromagnetic exploration characteristic factors is successful.

[0104] comparing the transmission process analysis factor with a transmission process analysis threshold stored in a database;

[0105] If the transmission process analysis factor is not lower than the transmission process analysis threshold, the geophysical electromagnetic exploration characteristic factor corresponding to the transmission process analysis factor is successfully transmitted, and a transmission success notification is issued;

[0106] If the transmission process analysis factor is lower than the transmission process analysis threshold, the geophysical electromagnetic exploration characteristic factor corresponding to the transmission process analysis factor is not successfully transmitted, and a retransmission instruction is issued.

[0107] Transmission latency refers to the time it takes for data to travel from its source to its destination. In geophysical electromagnetic exploration, this involves the time it takes to transmit data from field equipment to a data center or control room. Latency is usually measured using network equipment. Transmission signal strength reflects the power level of the signal during transmission. Signal strength directly affects the clarity and availability of data. Low signal strength may result in data loss or errors. Signal strength is usually monitored by data transmission equipment (such as the transmitting and receiving ends of a radio transmission system). Packet loss rate refers to the proportion of data packets lost during data transmission to the total number of data packets. In geophysical electromagnetic exploration data transmission, a high packet loss rate can affect data integrity and analysis quality. The measurement of packet loss rate usually relies on network analysis tools and software.

[0108] By monitoring parameters such as transmission delay, signal strength, and packet loss rate, the integrity of data during transmission can be ensured. This is critical for geophysical exploration, which relies on accurate data for geological analysis and decision-making. Monitoring transmission quality and quickly retransmitting when problems are detected can significantly improve the efficiency of overall data transmission. Such an automated process reduces the need to manually check and correct data errors, saving time and resources. By comparing with thresholds in the database, a large number of data transmission tasks can be automatically managed to ensure that only data with qualified quality is ultimately stored and analyzed. This approach improves the efficiency and quality of data management. Incorrect data transmission may lead to subsequent analysis errors. Automatically detecting and retransmitting data below the quality threshold can significantly reduce analysis errors caused by poor data quality.

[0109] The method of obtaining the transmission process analysis factor is as follows:

[0110] ;

[0111] In the formula, is the transmission process analysis factor, sy is the transmission delay of the geophysical electromagnetic exploration characteristic factor, qd is the transmission signal strength of the geophysical electromagnetic exploration characteristic factor, db is the transmission packet loss rate of the geophysical electromagnetic exploration characteristic factor, , , They are the compensation factors of the set sy, qd, and db respectively.

[0112] By analyzing these factors, we can comprehensively evaluate the propagation quality of electromagnetic signals, understand the delay, attenuation and loss of signals during transmission, and help determine whether the signal is reliable and whether it meets the quality requirements of exploration data transmission. In geophysical electromagnetic exploration, a large amount of data often needs to be transmitted through electromagnetic waves. Analyzing factors such as delay and packet loss rate during transmission can help design more efficient transmission protocols or data encoding methods, reduce data loss or repeated transmission, and thus improve the overall efficiency of data transmission. The analysis of transmission factors can help identify potential sources of interference or propagation obstacles, so that measures can be taken in advance to avoid signal quality degradation or transmission failure, ensuring the smooth progress of the exploration process.

[0113] like Figure 3 As shown, a geophysical survey method, based on the above-mentioned geophysical survey system, comprises the following steps:

[0114] Analyze the geophysical electromagnetic exploration characteristics and obtain the geophysical electromagnetic exploration characteristic constraint signal;

[0115] Collect and analyze the correction impact data of the geophysical electromagnetic exploration process to determine the correction factor of the geophysical electromagnetic exploration process;

[0116] Based on the correction factor of the geophysical electromagnetic exploration process, the geophysical electromagnetic exploration characteristic constraint signal is corrected to obtain the geophysical electromagnetic exploration characteristic factor;

[0117] Transmit the geophysical electromagnetic exploration characteristic factors to the data center, analyze the transmission process of the geophysical electromagnetic exploration characteristic factors, and determine whether the transmission of the geophysical electromagnetic exploration characteristic factors is successful:

[0118] If the geophysical electromagnetic exploration characteristic factor is successfully transmitted, a transmission success notification is issued;

[0119] If the transmission of the geophysical electromagnetic exploration characteristic factors is unsuccessful, a retransmission instruction is issued.

[0120] Taking an example to illustrate the system and method of the present embodiment, the exploration conductivity is 3.0S / m, the exploration magnetic susceptibility is 1.2, the exploration electromagnetic wave attenuation rate is 0.8, the compensation factor of the exploration conductivity is 1.1, the compensation factor of the exploration magnetic susceptibility is 1.3, and the compensation factor of the exploration electromagnetic wave attenuation rate is 1.0, and the calculated geophysical electromagnetic exploration characteristic constraint signal is 2.0695.

The noise constraint factor is calculated to be 74.584.

[0122] The ambient temperature is 25°C, the ambient groundwater level is 15m, the ambient soil conductivity is 2.0S / m, the compensation factor of ambient temperature is 1.1, the compensation factor of ambient groundwater level is 1.3, the compensation factor of ambient soil conductivity is 1.4, and the calculated environmental constraint factor is 6.212.

[0123] The formation dip is 30°, the vertical thickness of the geological layer is 50m, the rock density is 2.5g / cm, the compensation factor of the formation dip is 1.2, the compensation factor of the vertical thickness of the geological layer is 1.4, and the compensation factor of the rock density is 1.6.
