[0026] Example 1

[0027] Figure 1 This document provides a flowchart of a method for determining the source of geothermal water recharge according to Embodiment 1 of the present invention. This embodiment is applicable to geothermal resource exploration scenarios, particularly for determining the source of geothermal water recharge. This method can be executed by a device for determining the source of geothermal water recharge, which can be implemented in hardware and / or software and can be configured in an electronic device. Figure 1 As shown, the method includes:

[0028] S110. Obtain the hydrogen isotope content and oxygen isotope content of water samples from each sampling point in the target area.

[0029] This method can be executed by electronic devices such as computers and servers. The target area can be a geothermal research area. Researchers can set up multiple sampling points within the target area according to its geographical features such as area, shape, and elevation. Researchers can collect water samples at each sampling point and determine the hydrogen and oxygen isotope content of the water samples at each sampling point using equipment such as isotope mass spectrometers.

[0030] Optionally, each sampling point in the target area can be a sampling location for different types of water bodies.

[0031] The target area can include water bodies of various types, such as shallow groundwater, river water, geothermal well water, and hot spring water. Sampling points can be set up within the distribution areas of different types of water bodies. Water samples from different sampling points can reflect the characteristics of the water body at that location, which is beneficial for the refined identification of geothermal water recharge sources at various locations within the target area.

[0032] Understandably, the hydrogen and oxygen isotope compositions of water bodies from different sources exhibit specific characteristics due to varying environmental conditions during their formation and circulation. Accurate measurement of hydrogen and oxygen isotope content can provide a basis for determining the source of replenishment. Hydrogen exists in nature in the form of three isotopes: protium, deuterium, and tritium. Due to the isotope fractionation effect during water vapor evaporation and condensation—that is, deuterium and oxygen isotopes fractionate simultaneously during phase transitions, and the fractionation ratio is relatively fixed—the hydrogen isotope content can be used to determine the deuterium abundance.

[0033] S120. The hydrogen isotope content and oxygen isotope content of the water samples at each sampling point are used as the water characteristic points of each sampling point.

[0034] Electronic devices can use the hydrogen and oxygen isotope contents of water samples from each sampling point as water feature points for each sampling point, for example, represented as... .

[0035] S130. Determine the geothermal water recharge source for each sampling point based on the positional relationship between the water feature points at each sampling point and the atmospheric precipitation line in the target area; the geothermal water recharge source includes atmospheric precipitation and non-atmospheric precipitation.

[0036] As is easily understood, atmospheric precipitation lines characterize the hydrogen content of atmospheric precipitation in a specific region. ) and oxygen ( The data expression for the linear relationship of isotopic composition. Atmospheric precipitation lines in the target area can characterize regional features such as water vapor transport paths, evaporation and distillation intensity, and climate environment. The offset patterns of water feature points at sampling points relative to the atmospheric precipitation lines in the target area can reflect the physicochemical processes experienced by the water body at that sampling point during circulation, thus providing important clues for determining the source of geothermal water recharge.

[0037] The electronic equipment can obtain atmospheric precipitation lines for the target area from a meteorological platform in advance, or collect precipitation samples from the target area within a preset time period to plot the atmospheric precipitation lines for the target area. The electronic equipment can compare the water feature points at each sampling point with the atmospheric precipitation lines of the target area to determine the distribution and offset patterns of the water feature points at each sampling point relative to the atmospheric precipitation lines of the target area. Based on the distribution and offset patterns of the water feature points at each sampling point relative to the atmospheric precipitation lines of the target area, the geothermal water recharge source for each sampling point can be determined. In this scheme, the geothermal water recharge sources can include atmospheric precipitation and non-atmospheric precipitation. Non-atmospheric precipitation sources can include river infiltration, mountain precipitation infiltration, and local circulation.

[0038] The technical solution of this invention involves obtaining the hydrogen and oxygen isotope contents of water samples from various sampling points in a target area; using these contents as water feature points for each sampling point; and determining the geothermal recharge source for each sampling point based on the positional relationship between these feature points and the atmospheric precipitation line in the target area. The geothermal recharge source includes both atmospheric and non-atmospheric precipitation. This technical solution solves the problem of inaccurate geothermal recharge source identification by using the atmospheric precipitation line in the target area as a reference, thus achieving accurate identification of the geothermal recharge source. It is applicable to geothermal recharge research under different hydrogeological conditions.

[0039] Example 2

[0040] Figure 2 This is a flowchart illustrating a method for determining a geothermal water recharge source according to Embodiment 2 of the present invention. This embodiment is a refinement based on the above embodiment. Figure 2 As shown, the method includes:

[0041] S210. Obtain the hydrogen isotope content and oxygen isotope content of water samples from each sampling point in the target area.

[0042] S220. The hydrogen isotope content and oxygen isotope content of the water samples at each sampling point are used as the water characteristic points of each sampling point.

[0043] In a feasible scheme, before determining the geothermal water recharge source for each sampling point based on the positional relationship between the water feature points at each sampling point and the atmospheric precipitation line in the target area, the method further includes:

[0044] Acquire multiple atmospheric precipitation sample points in the target area within a preset time period; the collection time and / or collection location of the atmospheric precipitation samples matched by each atmospheric precipitation sample point are different; the atmospheric precipitation sample points are determined based on the hydrogen isotope content and oxygen isotope content of the atmospheric precipitation samples;

[0045] The atmospheric precipitation line for the target area is obtained by fitting each atmospheric precipitation sample point using linear regression.

[0046] Based on the above scheme, the expression for the atmospheric precipitation line is:

[0047] ;

[0048] in, Indicates hydrogen isotope content, Indicates oxygen isotope content. , These represent the coefficients of a linear function.

[0049] Electronic devices can pre-acquire multiple atmospheric precipitation sample points within a preset time period for a target area, such as atmospheric precipitation sample points at multiple locations throughout the year. Each atmospheric precipitation sample point corresponds to one atmospheric precipitation sample. Different atmospheric precipitation sample points correspond to atmospheric precipitation samples collected at different times, locations, or both. Atmospheric precipitation sample points are determined based on the hydrogen and oxygen isotope content of the atmospheric precipitation samples, for example, represented as... .

[0050] Electronic devices can be For "y", with " Let "x" represent the value of the sample point. Based on linear regression, each atmospheric precipitation sample point can be directly fitted to a straight line. Alternatively, the electronic device can take the average oxygen isotope content of atmospheric precipitation samples collected from various locations at the same time point as the oxygen isotope content at that time point, and the average hydrogen isotope content of atmospheric precipitation samples collected from various locations at the same time point as the hydrogen isotope content at that time point. Based on the oxygen and hydrogen isotope contents at that time point, the atmospheric precipitation sample point at that time point can be determined. The electronic device can fit the atmospheric precipitation sample points at each time point to a straight line based on linear regression. Understandably, the fitted straight line can be represented by a linear function. "This indicates the atmospheric precipitation line for the target area."

[0051] This scheme can automatically fit the atmospheric precipitation line of the target area, which is conducive to flexibly delineating the scope of the target area and conducting targeted analysis of the geothermal water recharge sources of each sampling point in the target area.

[0052] S230. Determine whether the distance between the water feature point of the target sampling point and the atmospheric precipitation line of the target area is less than or equal to the preset distance threshold.

[0053] The electronic device can sequentially use each sampling point as a target sampling point, calculate the distance between the water feature point of the target sampling point and the atmospheric precipitation line of the target area, and determine whether the distance between the water feature point of the target sampling point and the atmospheric precipitation line of the target area is less than or equal to a preset distance threshold. It is easy to understand that the preset distance threshold can be a small distance value used to assess whether the water feature point of the target sampling point is close to the atmospheric precipitation line of the target area.

[0054] If the distance between the water feature point of the target sampling point and the atmospheric precipitation line of the target area is less than or equal to the preset distance threshold, then execute S240; if the distance between the water feature point of the target sampling point and the atmospheric precipitation line of the target area is greater than the preset distance threshold, then execute S250.

[0055] S240. The geothermal water recharge source for the target sampling point is determined to be atmospheric precipitation.

[0056] Understandably, if the distance between the water feature point of the target sampling point and the atmospheric precipitation line of the target area is less than or equal to the preset distance threshold, it means that the water feature point of the target sampling point is close to the atmospheric precipitation line of the target area, and the geothermal water supply of the target sampling point comes from atmospheric precipitation.

[0057] S250. The geothermal water recharge source for the target sampling point includes non-atmospheric precipitation.

[0058] If the distance between the water feature point of the target sampling point and the atmospheric precipitation line of the target area is greater than the preset distance threshold, it means that the water feature point of the target sampling point is far away from the atmospheric precipitation line of the target area. The geothermal water supply source of the target sampling point may be partly from atmospheric precipitation, partly from non-atmospheric precipitation, or entirely from non-atmospheric precipitation.

[0059] Based on the above scheme, after determining that the geothermal water recharge source for the target sampling point includes non-atmospheric precipitation, the method further includes:

[0060] Based on the geomorphic elevation and structural features of the target sampling point, the non-atmospheric precipitation recharge source of the target sampling point is determined.

[0061] If the geothermal recharge source at the target sampling point includes non-atmospheric precipitation, electronic equipment can further acquire the geomorphic elevation and structural features of the target sampling point to determine the specific non-atmospheric precipitation recharge source. Geomorphology refers to the naturally formed undulating shape of the ground, such as mountains, plains, and hills; elevation is the vertical distance from a ground point to the geoid, a parameter describing geomorphic characteristics. Structural features are used to describe the underground structure of the target sampling point, such as the presence of faults.

[0062] It's easy to understand that topographic elevation affects the isotopic composition of atmospheric precipitation, and fault structures are important channels for geothermal water migration. Electronic equipment can determine the non-atmospheric precipitation recharge sources of the target sampling point based on its topographic elevation and structural features, such as mountain precipitation infiltration, river infiltration, or local circulation.

[0063] Figure 3 This is a schematic diagram of the positional relationship between water feature points and atmospheric precipitation lines according to Embodiment 2 of the present invention. In a specific example, such as... Figure 3 As shown, sampling points marked with blue circles are distributed in the shallow groundwater area of ​​the target region, those marked with yellow circles are distributed in the Jurassic stratigraphic water area of ​​the target region, those marked with red pentagrams are distributed in the Permian stratigraphic water area north of the fault zone of the target region, and those marked with purple pentagrams are distributed in the Permian stratigraphic water area south of the fault zone of the target region. LMWL represents the atmospheric precipitation line of the target region, and GMWL represents the global atmospheric precipitation line. Based on a pre-set distance threshold, the sampling points are determined... Figure 3 The geothermal water recharge sources of sampling points 1-3 include non-atmospheric precipitation. Since sampling points 1-3 are located near the fault zone in the target area, it can be determined that the non-atmospheric precipitation source of sampling points 1-3 may be seepage water transported by the fault channel.

[0064] This approach combines hydrogen and oxygen isotope characteristics with geological conditions for multi-dimensional analysis, enabling accurate identification of geothermal recharge pathways under complex hydrogeological conditions and effectively addressing the problem of insufficient accuracy in identifying geothermal recharge sources. By systematically collecting various types of water samples, determining isotope content, and combining this with regional geological characteristics, different recharge sources can be distinguished, improving the reliability of geothermal system recharge research and providing a more solid foundation for geothermal resource assessment.

[0067] The isotope content acquisition module 310 is used to acquire the hydrogen isotope content and oxygen isotope content of water samples from each sampling point in the target area.

[0068] The feature point generation module 320 is used to use the hydrogen isotope content and oxygen isotope content of the water samples at each sampling point as water feature points at each sampling point.

[0069] The geothermal water recharge source determination module 330 is used to determine the geothermal water recharge source of each sampling point based on the positional relationship between the water feature points of each sampling point and the atmospheric precipitation line of the target area; the geothermal water recharge source includes atmospheric precipitation and non-atmospheric precipitation.

[0070] In this solution, the supply source determination module 330 is specifically used for:

[0071] If the distance between the water feature point of the target sampling point and the atmospheric precipitation line of the target area is less than or equal to the preset distance threshold, then the geothermal water recharge source of the target sampling point is determined to be atmospheric precipitation.

[0072] If the distance between the water feature point of the target sampling point and the atmospheric precipitation line of the target area is greater than the preset distance threshold, then the geothermal water recharge source of the target sampling point is determined to include non-atmospheric precipitation.

[0073] Based on the above solution, the device further includes:

[0074] The non-atmospheric precipitation recharge source determination module is used to determine the non-atmospheric precipitation recharge source of the target sampling point based on the geomorphic elevation and structural characteristics of the target sampling point after determining that the geothermal recharge source of the target sampling point includes non-atmospheric precipitation.

[0075] In one feasible embodiment, the device further includes:

[0076] The sample point acquisition module is used to acquire multiple atmospheric precipitation sample points in the target area within a preset time period before determining the geothermal water recharge source of each sample point based on the positional relationship between the water body characteristic points of each sampling point and the atmospheric precipitation line of the target area. The collection time and / or collection location of the atmospheric precipitation samples matched by each atmospheric precipitation sample point are different. The atmospheric precipitation sample points are determined based on the hydrogen isotope content and oxygen isotope content of the atmospheric precipitation samples.

[0077] The atmospheric precipitation line generation module is used to obtain the atmospheric precipitation line of the target area by fitting each atmospheric precipitation sample point based on linear regression.

[0078] Based on the above scheme, the expression for the atmospheric precipitation line is:

[0079] ;

[0080] in, Indicates hydrogen isotope content, Indicates oxygen isotope content. , These represent the coefficients of a linear function.
