Serpentinization is one of the primary causes of natural hydrogen. Iron-rich minerals in rocks react with water under certain temperatures and pressures to produce hydrogen. The degree of serpentinization determines the rock's hydrogen production potential. However, the exploration and evaluation of natural hydrogen is in its infancy. Currently, there are no mature and reliable methods for predicting and evaluating the hydrogen production potential of hydrogen source rocks. Furthermore, most areas are understudied, basic data is scarce, and the potential of hydrogen resources is unknown.

[0050] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0051] like Figure 1 As shown, a method for predicting the hydrogen generation potential of rocks according to an embodiment of the present invention includes:

[0052] S1. According to the rock Fe 3+ / Fe Tot ratio, and the Fe 3+ / Fe Tot The relationship between the ratio and the degree of serpentinization is used to calculate the degree of serpentinization of the rocks in the study area. 3+ / Fe Tot The ratio is Fe in rock 3+ The ratio of mass to the total iron mass in the rock;

[0053] S2. Predict the hydrogen generation potential of the rocks in the study area based on the serpentinization degree of the rocks in the study area and the relationship between the hydrogen generation potential of the rocks and the serpentinization degree.

[0054] In certain embodiments of the present invention, the Fe content of the rock in step S1 is 3+ / Fe Tot The relationship between the ratio and the degree of serpentinization is obtained, including:

[0055] A1. Collect Fe of target rock 3+ / Fe Tot Ratio data and serpentinization degree data, wherein the target rock is a hydrogen source rock to ensure the authenticity and reliability of subsequent data analysis;

[0056] Hydrogen source rocks are mostly basic-ultramassic rocks in the basement of sedimentary basins, corresponding to a depth of about 10 km;

[0057] Therefore, for example, in the embodiment of the present invention, the global Fe-rich 2+ Basic-ultrabasic rock Fe of mineral (olivine) 3+ / Fe Tot ratio data and serpentinization degree data;

[0058] A2. Fe of target rock 3+ / Fe Tot The ratio data and the serpentinization degree data are subjected to a first fitting analysis, i.e., a first fitting analysis is performed based on the data collected in step A1. The specific first fitting analysis process includes linear fitting, logarithmic fitting, and exponential fitting, etc., wherein the fitting technology is an existing mathematical analysis method and will not be described in detail here;

[0059] A3. According to the first fitting analysis result, the Fe 3+ / Fe Tot The relationship between the ratio and the degree of serpentinization, according to the results of the first fitting analysis in step A2, shows that the Fe 3+ / Fe Tot The ratio has a good positive correlation with the degree of serpentinization, and the linear correlation coefficient R2 is 0.85;

[0060] The Fe3+ / Fe Tot The relationship between the ratio and the degree of serpentinization is shown in formula (1):

[0061] S=K1φ+B1 (1)

[0062] In formula (1), S is the degree of serpentinization, φ is Fe 3+ / Fe Tot Ratio, K1 is a constant, B1 is a constant.

[0063] For example, in the embodiment of the present invention, K1 is 139.86, B1 is 7.3105, and substituting them into formula (1) yields formula (2);

[0064] S=139.86φ+7.3105 (2)

[0065] In some embodiments of the present invention, step S1 is to study the rock Fe 3+ / Fe Tot Substitute the ratio into the Fe 3 + / Fe Tot The serpentinization degree of the rocks in the study area was calculated from the relationship between the ratio and the serpentinization degree.

[0066] In certain embodiments of the present invention, the relationship between the hydrogen generation potential of the rock and the degree of serpentinization in step S2 includes:

[0067] B1. Performing a second fitting analysis on the serpentinization degree data and hydrogen generation potential data of the target rock, i.e., performing a second fitting analysis on the serpentinization degree data and hydrogen generation potential data of the hydrogen source rock. The specific second fitting analysis process includes linear fitting, logarithmic fitting, and exponential fitting, etc., wherein the fitting technology is an existing mathematical analysis method and is not described in detail here;

[0068] B2. Based on the second fitting analysis results, the relationship between the hydrogen generation potential and the serpentinization degree of the rock is obtained. That is, based on the results of the second fitting analysis in step B1, it is found that the relationship between the hydrogen generation potential and the serpentinization degree includes a first stage and a second stage, the serpentinization degree corresponding to the critical values ​​of the first stage and the second stage is the serpentinization degree threshold, and the hydrogen generation potential corresponding to the critical values ​​of the first stage and the second stage is the hydrogen generation potential threshold;

[0069] In the first stage, that is, when the serpentinization degree is less than or equal to the serpentinization degree threshold, the relationship between the hydrogen generation potential and the serpentinization degree is shown in the following formula:

[0070] P(H2)= K2S+B2 (3)

[0071] In the second stage, that is, when the serpentinization degree is greater than the serpentinization degree threshold, the relationship between the hydrogen generation potential and the serpentinization degree is shown in the following formula:

[0072] P(H2)= K3S -C (4)

[0073] In formulas (3)-(4), P(H2) is the hydrogen generation potential, which represents the fluid hydrogen concentration produced by the formation of unit mass of serpentine, K2, K3 and C are all positive numbers, and B2 is a constant.

[0074] In some embodiments of the present invention, step S2 includes:

[0075] S2-1, comparing the serpentinization degree of the rocks in the study area calculated in step S1 with the serpentinization degree threshold;

[0076] S2-2. Based on the result that the calculated serpentinization degree of the rocks in the study area is less than or equal to the serpentinization degree threshold, the hydrogen generation potential of the rocks in the study area is predicted according to the calculated serpentinization degree of the rocks in the study area and formula (3). Specifically, the calculated serpentinization degree of the rocks in the study area is substituted into formula (3) to calculate the hydrogen generation potential of the rocks in the study area, that is, the predicted value of the hydrogen generation potential of the rocks in the study area;

[0077] S2-3. Based on the result that the serpentinization degree of the rocks in the study area obtained by comparison is greater than the serpentinization degree threshold, the hydrogen generation potential of the rocks in the study area is predicted based on the calculated serpentinization degree of the rocks in the study area and formula (4). Specifically, the calculated serpentinization degree of the rocks in the study area is substituted into formula (4) to calculate the hydrogen generation potential of the rocks in the study area, that is, the predicted value of the hydrogen generation potential of the rocks in the study area.

[0078] For example, in the embodiment of the present invention, K2 is set to 13, B2 is set to 0, and substitution into formula (3) yields formula (5):

[0079] P(H2)= 13S (5)

[0080] For example, the unit of P(H2) is mM / Kg; S is the degree of serpentinization of the hydrogen source rock, in %.

[0081] For example, in the embodiment of the present invention, K3 is set to 14076, and C is set to 1.919. Substituting them into formula (4) yields formula (6):

[0082] P(H2)= 14076 S -1.919 (6)

[0083] For example, the unit of P(H2) is mM / Kg; S is the degree of serpentinization of the hydrogen source rock, in %.

[0084] For example, in an embodiment of the present invention, the serpentinization degree threshold is 10%, and when the serpentinization degree is 10%, the hydrogen generation potential reaches a maximum value, and the H2 fluid concentration generated when 1 kg of serpentine is generated is approximately 130 Mm, that is, the hydrogen generation potential threshold is 130 Mm / kg;

[0085] When the serpentinization degree is less than or equal to 10%, the calculated serpentinization degree is substituted into formula (5) to obtain the hydrogen generation potential of the rocks in the study area; when the serpentinization degree is greater than 10%, the calculated serpentinization degree is substituted into formula (6) to obtain the hydrogen generation potential of the rocks in the study area.

[0086] According to the prediction method provided in the above embodiment, the hydrogen generation potential of rocks in a certain study area was evaluated. The specific steps include:

[0087] According to step S1, the rock Fe 3+ / Fe Tot Substitute the ratio into the Fe 3+ / Fe Tot The relationship between the ratio and the degree of serpentinization (i.e., formula (2)) is used to calculate the degree of serpentinization of the rocks in the study area;

[0088] In order to verify the accuracy of the calculated value of the serpentinization degree of the rocks in the study area obtained in step S1 of the method of the present invention, a comparison chart of the calculated value and the measured value of the serpentinization degree of the rocks in the study area is provided here, specifically see Figure 2 , where the calculated value is the point on the straight line corresponding to formula (2), and the test value is Figure 2 The data points in Figure 2 It can be seen that the error between the calculated value obtained in step S1 and the test value is very small;

[0089] According to step S2, the serpentinization degree of the rocks in the study area is calculated based on the rocks in the area, and the relationship between the hydrogen generation potential of the rocks and the serpentinization degree is used to predict the hydrogen generation potential of the rocks in the study area. Specifically,

[0090] The calculated value of the serpentinization degree obtained in step S1 is compared with the serpentinization degree threshold value (10%), and the result of the comparison is substituted into formula (5) or (6). Here, in the embodiment of the present invention, a curve diagram of the hydrogen generation potential predicted according to the serpentinization degree is given as an example, as shown in FIG. Figure 3 .

[0091] According to certain embodiments of the present invention, a method for evaluating the hydrogen generation potential of rocks is provided, comprising:

[0092] X1. Comparing the serpentinization degree and serpentinization degree threshold of the rocks in the study area calculated by the prediction method described in the above embodiment;

[0093] X2. When the calculated serpentinization degree of the rocks in the study area is less than or equal to the serpentinization degree threshold, the hydrogen generation capacity of the rocks in the study area is evaluated based on the serpentinization degree of the rocks in the study area. For example, if the calculated serpentinization degree of the rocks in the study area is less than or equal to 10%, the hydrogen generation capacity of the rocks in the study area is considered to be the first level (the highest level);

[0094] X3. When the calculated serpentinization degree of the rocks in the study area is greater than the serpentinization degree threshold, the hydrogen generation capacity of the rocks in the study area is evaluated based on the predicted hydrogen generation potential of the rocks. For example, if the calculated serpentinization degree of the rocks in the study area is greater than 10%, the hydrogen generation capacity of the rocks in the study area is evaluated based on the predicted hydrogen generation potential of the rocks in the above embodiment.

[0095] For example, the hydrogen generation potential corresponding to a serpentinization degree of 10% (i.e., the hydrogen generation potential threshold) is used as a comparison benchmark, and the predicted rock hydrogen generation potential is compared with the benchmark value. The hydrogen generation capacity is classified according to the comparison result, such as the hydrogen generation capacity is classified according to the difference between the two values, or the hydrogen generation capacity is classified according to the quotient of the two values. The present invention does not specifically limit this specific classification.

[0096] From the relationship between the hydrogen generation potential and the degree of serpentinization reflected by formula (3) and formula (4), it can be seen that in the first stage, the hydrogen generation potential of the hydrogen source rock increases with the increase of the degree of serpentinization; in the second stage, the hydrogen generation potential of the hydrogen source rock decreases with the increase of the degree of serpentinization. Therefore, the hydrogen generation potential threshold is the maximum value of the hydrogen generation potential. When the serpentinization degree of the rock in the study area is greater than the serpentinization degree threshold, the hydrogen generation capacity of the rock in the study area is lower than the hydrogen generation capacity of the rock in the study area when the serpentinization degree of the rock in the study area is less than or equal to the serpentinization degree threshold.
