How much does it cost to drill a geothermal well per meter

Hot spring drilling technology is not only influenced by the drilling technology itself, but also has its special characteristics of geothermal drilling. Based on the results of the previous geothermal exploration, a drilling process and drilling plan tailored to local conditions are formulated, and corresponding technical equipment is used. From leveling the site to hot spring well formation, the preparation, drilling, and logging of each link need to be emphasized in the construction plan according to the geological conditions, drilling conditions, and hot spring heating requirements. Targeted technologies should be adopted, and engineering testing should also be emphasized during the drilling process, including analyzing and diagnosing the detection data obtained underground, timely handling abnormal states, and responding to various complex working conditions. After the completion of hot spring drilling, regular post maintenance should also be carried out. In addition to preventing corrosion and scaling to avoid a decrease in water volume and water temperature, it is also necessary to prevent ground subsidence and, if necessary, recharge to maintain the thermal balance of groundwater. Only by comprehensively and meticulously treating every aspect of hot spring drilling can we ensure the smooth, efficient, high-yield, and sustainable operation of the entire project. After the exploration project is determined, preliminary data collection is carried out according to project needs (collecting geological, geothermal, and geophysical data of the project area and surrounding areas, with a focus on collecting data on water sources and single well exploration results near the work area), in order to preliminarily understand the regional geological structure, hydrogeological conditions, etc. of the project area, and lay the foundation for geological survey work in the project area.

Like other drilling methods, hot spring drilling also has its own special drilling techniques, as it targets underground hot water, a special mineral that requires corresponding equipment and technology for the development of hot spring wells. Different geological types also have different requirements for drill bits and other consumables. Therefore, based on the previous hot spring exploration, corresponding hot spring drilling techniques and design plans need to be formulated to make hot spring drilling more efficient and smooth. Before carrying out hot spring well construction, it is necessary to conduct a hot spring survey. In hot spring exploration, it is necessary to understand the location of the hot spring underground, as well as the storage and supply situation. It is also necessary to comprehensively grasp the geological conditions of the hot spring project location, including the lithology and structure of the underground rock layers, as well as the situation of the aquifer. A survey report should be formed to provide a basis for later planning and drilling. Early exploration is essential. We cannot settle things hastily just because we are afraid of trouble and cost. The early stage of hot spring exploration determines the overall success of the hot spring well. Scientific and professional hot spring exploration can reasonably avoid the risks of hot spring drilling, including the risk of accidents during drilling and the risk of successful water discharge. Hot spring development, hot spring well heating, geothermal agriculture, and other fields all require good hot spring well engineering to have sufficient geothermal energy for utilization. The development of these industries also promotes the development of technology and equipment for hot spring well drilling, and enables various modes of geothermal drilling to be widely used. This has greatly developed the hot spring well market and has a good prospect. In the future, there will be waves of development. How to choose a design and construction unit for hot springs is a problem that investors need to consider.
