Specifically, the geothermal associated gas resource amount (Q) may be obtained based on the groundwater reserve (R w) in the thermal reservoir in the geothermal system and the calculated absolute content (C) of the geothermal gas, the calculation formula being shown below; the groundwater reserve (R w) in the thermal reservoir is calculated from the thickness (H, unit: m) of the thermal reservoir, the distribution area (A, unit: m 2) of the geothermal zone, and the porosity (Φ) of the thermal reservoir rock, as follows:

The following describes and illustrates the embodiments of the present application in detail with reference to specific examples of application:
Illustratively, geothermal resources of a certain region are described as an example. In recent years, with exploitation and research of geothermal resources, it has been found that accompanying gas hydrogen and helium in geothermal gas in the region are abnormally high. When the helium concentration reaches 0.05-0.1vol.%, the method has industrial value, can be used as helium reservoir exploitation, and the hot water in the area can be accompanied with helium resources reaching 0.53vol.%, which exceeds the industrial value standard. In addition, the detected hydrogen is up to 12.45vol.%, far beyond other areas. However, due to the limitation of the existing sampling method, only the relative content of the gas can be obtained, and the absolute content of the helium and the hydrogen can not be obtained, so that the resource amount potential of the helium and the hydrogen can not be known for a long time. Therefore, according to the geothermal gas absolute content calculation method provided by the embodiment of the application, the absolute content of helium and hydrogen in geothermal gas of a geothermal system in the region is calculated, so that geothermal associated gas resource potential is obtained, and the method comprises the following steps:

The relative content of helium is measured to be 0.04-0.53 vol.% and the relative content of hydrogen is measured to be 2.38-12.45 vol.%.
The corresponding constants a 1,A2,A3,B1,B2,B3 in the absolute content calculation formula (4) of helium gas can be obtained by looking up table 1, and A1＝-34.6261,A2＝43.0285,A3＝14.1391,B1＝-0.04234,B2＝0.022624,B3＝-0.003312, is brought into the calculation formula (4) to obtain the calculation formula (7), and the absolute content of helium gas is obtained based on the calculation formula (7) to be 4.0x -6 to 5.3x -5cm3 STP g-1H2 O, and specific reference can be made to table 2.
Table 2 helium absolute content calculation parameters
The corresponding constants a 1,A2,A3,B1,B2,B3 in the equation (4) for the absolute content of hydrogen can be obtained by looking up table 1, and A1＝-47.8948,A2＝65.0368,A3＝20.1709,B1＝-0.082225,B2＝0.049564,B3＝-0.0078689, is brought into equation (4) to obtain equation (8), and the absolute content of hydrogen is 4.1X10 -4 to 2.1X10 -3cm3 STP g-1H2 O based on equation (8), for details, refer to table 3.
