Embodiment

[0024] Embodiment: a kind of high-efficiency geothermal resource prospecting method based on computer simulation technology, comprises the following steps:

[0025] 1) Geological survey, select an area, and combine the previous oil exploration data and geological survey data in this area to find out the stratigraphic age, lithological characteristics, geological structure and magmatic activity of the geothermal field. The scale of the geological survey map should be selected for regional maps. 1 / 100,000-1 / 25,000, geothermal field maps should choose 1 / 50,000-1 / 25,000;

[0026]2) Geochemical surveys. Geochemical surveys should be carried out at all stages of geothermal resource exploration. Representative geothermal fluids, normal-temperature groundwater, surface water, and atmospheric precipitation samples should be taken for laboratory analysis, and the relationship between them and geothermal fluids should be compared and analyzed. , carry out temperature scale calculations, ...

Abstract

The invention relates to the technical field of a geothermal resource, and discloses an efficient geothermal resource exploration method based on a computer simulation technology. The efficient geothermal resource exploration method comprises the following steps of carrying out geological survey; selecting a region; and combined with the data of previous petroleum exploration and geological surveyin the region, ascertaining the stratigraphic age, lithologic characteristics, the geological structure and the magmatic activity of a geothermal field. About the measuring scale of geological surveymaps, the regional map should selects 1/100,000-1/25,000, and the geothermal field map should select 1/50,000-1/25,000. According to the efficient geothermal resource exploration method based on thecomputer simulation technology, through experimental analysis, a system adopts water, gas, rock and soil samples for analysis and identification, and the relevant parameters of heat storage are obtained; the geological profile information and the existing geothermal information are obtained after computer data simulation, and the distribution of geothermal resources was calculated by a computer summing up the template formula; and thus, a lot of manual analysis time can be saved, the efficiency is improved, and manpower is saved.

Description

technical field [0001] The invention relates to the technical field of geothermal resources, in particular to an efficient geothermal resource exploration method based on computer simulation technology. Background technique [0002] Geothermal resources refer to the renewable heat energy stored in the interior of the earth. They are generally distributed along the edge of the tectonic plate. They originate from the decay of the earth's molten magma and radioactive substances. Geothermal resources are a very valuable comprehensive mineral resource with multiple functions. It is not only a clean energy resource, which can be used for power generation and heating, but also a hot brine resource and natural fertilizer resource for extracting industrial raw materials such as bromine, iodine, borax, potassium salt and ammonium salt. At the same time, it is also a valuable source of medical hot mineral water, drinking mineral water and domestic water supply. [0003] In the traditi...
