How much does it cost to drill a 1500 meter hot spring well

After the survey and before drilling, it is necessary to plan the hot spring resources, using as much hot water as possible without wasting or exhausting it. Not only should a comprehensive utilization plan be made for each temperature gradient of the hot spring, but also the geographical area of the hot spring should be divided, including how many wells can be drilled and what applications each well in the area is used for. At the same time, the hot spring supply network should be planned to strive for the utilization of hot spring resources, which is also a way to reduce costs and increase output. The hot spring well is a costly link in the entire hot spring development, and it is also an important factor that determines the success or failure of the entire hot spring development. Geothermal exploration is the exploration and investigation of the geological conditions and geothermal resource reserves in the development area. Through a series of disciplinary knowledge and technical methods in geology, geothermal science, geophysics, and geochemistry, as well as measurement data, comprehensive opinions are proposed for the development of geothermal resources in the project area after testing and analysis, including geological conditions for drilling, location and depth of geothermal drilling, possible situations during construction and proposed response plans, geothermal utilization engineering and later maintenance, and a series of data foundations and guidance suggestions. To lay a scientific foundation for the smooth implementation of geothermal drilling and long-term geothermal development projects. It is also necessary to develop drilling techniques and plans that are tailored to local conditions based on the survey. Many hot springs with abundant reserves. Hot spring exploration is not only for surveying hot springs, but also for understanding geological conditions, providing drilling technology and planning basis for hot spring drilling, and avoiding potential geological risks encountered in the project as much as possible. Based on a comprehensive analysis of existing data, according to the geological survey work plan of the project area, the hydrological conditions of geothermal wells, oil and gas wells, agricultural wells, drinking water wells, etc. are focused on the project area and surrounding areas. Through geological, geothermal geological, oil and gas point, geological point investigation, GPS positioning, manual investigation and other methods, combined with project data research, analyze the geological structure, lithological characteristics, geological structure, hydrogeological conditions, distribution, enrichment, runoff and discharge laws of groundwater in the project work area, and further understand and comprehend the geothermal geological conditions in the project work area, laying a good foundation for physical and chemical testing work.

Take complete and accurate rock samples of the target thermal reservoir and its cap rock; Identify the corresponding stratigraphic structure, geological structure, lithology, geothermal changes, permeability of thermal reservoirs, geothermal fluid pressure, physical properties, and chemical composition of the well; Understand the insulation conditions of the cover layer and the mining technology conditions of geothermal resource reservoirs; Identify the pressure, water level, temperature, flow rate, and geothermal fluid quality of the thermal storage, and carry out hydrogeological work for the well in accordance with specifications or contract requirements; Identify geothermal geological conditions and obtain representative calculation parameters for evaluating geothermal resources, etc; Geothermal energy extraction and other rock debris logging records the rock debris logging intervals and spacing, and carries out lithology naming, lithology description, and determination of stratification depth. Close to the lower layer of the pipeline, it is necessary to extract more tightly to accurately determine the formation. If geothermal exploration holes have the conditions to be drilled, they should be drilled according to the requirements of geothermal production drilling technology, and after completion, they should be converted into production wells for utilization; Geothermal production wells should be drilled according to the technical requirements of geological exploration holes, and all drilling geological and geothermal parameter data should be taken accurately. Geological logging should be done well to provide geological data for geothermal field geological research and resource development and protection. The diameter of the exploration well should meet the requirements of sampling logging and installation of pumping test equipment after completion. The combined well of exploration and exploitation should also meet the requirements of the designed pumping capacity and waterproof filling material of the production well. Geophysical logging should be carried out during drilling and after completion of the exploration well. The general wellbore section should include parameters such as wellbore diameter, inclination, resistivity, natural potential, natural gamma, wellbore temperature, and bottomhole temperature. The depth is determined according to the burial depth of the thermal reservoir. Obtain a certain amount of hot water and steam that can be used for power generation or other industrial purposes, using oil well casing procedures and completion methods.
