The geothermal exploration work in geothermal energy follows scientific principles, and the basic workflow includes: basic geological data research, field geothermal geological investigation, geochemical investigation, geophysical exploration, special hydrogeological investigation, geothermal drilling, etc. The hot springs developed by deep drilling now are fundamentally different from the original ones. What's the difference? Firstly, there is a difference in temperature. The original hot springs were located in geothermal (volcanic) areas. But now the hot springs developed by deep drilling often have temperatures below 50 ℃, and require heating to be used in easily accessible places and times as conditions for developing hot springs. Hot springs are constantly being developed in the suburbs of cities. Therefore, the location of hot spring development is far from the volcano and not in the subtropical zone. Like other industries, hot spring drilling is charged based on the engineering of each link, which depends on several factors. From the perspective of underground factors, the main factor determining the price is depth, and the deeper the depth, the higher the price. This is determined by the difficulty caused by the complexity of deep geological formations. Necessary geothermal exploration should be conducted before drilling, and the cost of drilling may vary in areas with different geological and geothermal conditions. Geothermal drilling technology refers to the process of drilling holes and obtaining geological profile data through geothermal drilling. It is also necessary to conduct pumping tests to determine the water level, quantity, and quality of groundwater, and sometimes build it into a tube well for long-term water supply. The various technical measures taken for this purpose are called "geothermal drilling drilling technology" drilling types: geothermal well drilling types mainly include metamorphic rock drilling, sedimentary rock drilling, igneous rock drilling, comprehensive drilling, etc.

Geothermal exploration is a very instructive work in geothermal energy development, without which it is impossible to understand the condition of underground geothermal resources The development of hot springs has truly entered the engineering stage, which still relies on geothermal exploration. Geothermal exploration can guide hot spring drilling, provide reliable basis for the formulation of hot spring drilling plans, the selection of geothermal drilling equipment, and the adoption of geothermal drilling technology and processes. Accurate understanding of the reserves, burial depth, and geological environment of geothermal resources in the surrounding area is essential for geothermal drilling. Blindly drilling without producing hot water can result in significant losses. After geothermal exploration, geothermal planning can also make geothermal energy drilling more cost-effective Accurate understanding of the reserves, burial depth, and geological environment of geothermal resources, as well as the surrounding area, is essential for geothermal drilling to have a basis and prevent blind drilling without producing hot water, ultimately resulting in significant losses Geothermal drilling believes that there are often problems with underground water systems in the surrounding area during specific drilling operations Geothermal drilling believes that if the positive circulation drilling construction technology is chosen during the drilling process, the drill rod will directly transport most of the flushing fluid (drilling mud) to the bottom of the hole, which will result in a large amount of rock powder and debris being produced, and will also flow into the well at the same time as the water flow, making the water increasingly turbid and leading to groundwater pollution Hot spring resource exploration refers to the use of theories and exploration techniques from geological surveys, geophysics, geochemistry, geothermal drilling, and other fields to solve key technical problems related to the geological background, ore controlling factors, distribution areas, resource reserves, quality, and development suitability of geothermal formation. Thus, evaluate the hot spring resources, provide a basis for geothermal drilling plans, and propose feasibility reports for geothermal development.
