After the survey is completed, the drilling construction project can be started according to the drilling design model, and the drilling project is the most invested part of the whole hot spring well drilling. The price of drilling construction works is determined by comprehensive factors such as geographical location, geological conditions, resource conditions, depth of project design drilling, industry market conditions, selection of drilling construction teams, selection of drilling equipment, and method of using hot spring wells.

1. Influence of geological conditions on hot spring wells

Geological conditions have a great impact on drilling. The more complex the underground conditions are, the higher the risk of hot spring drilling, and the more means and equipment that need to be used. will be different, therefore, different underground geological conditions will also affect the price of hot spring drilling.

For example, regardless of the resource factor, the price of drilling a hot spring well with a depth of 2,000 meters is different from that of a hot spring well with a depth of 5,000 meters. The price of deep geothermal wells ranges from 4000-10000 yuan/meter. The deeper the drilling, the more expensive, because the deeper the drilling, the higher the overall equipment requirements, the greater the difficulty of drilling, so the higher the price.

2. Selection of construction team

The selection of the construction team itself will affect the price of drilling, which is related to the local market conditions in which the construction team is located, and is related to the type and level of the construction team. A good drilling construction team is not only responsible for the construction, but also controls the construction quality, construction progress and construction safety of the entire drilling process, and at the same time monitors the data in real time to observe whether the rock formation properties at each stage are consistent with the rock formation properties predicted by the previous exploration. The construction progress, method, and equipment selection need to be adjusted or not. A drilling construction team with many years of construction experience and excellent professional skills can reduce the risk of drilling construction to a certain extent.

3. Selection of drilling equipment

Different underground rock properties and rock formations have different requirements for technology and equipment, and the prices of different equipment and drilling consumables, loss and consumption are also different, which also constitutes the difference in the price of hot spring wells. In addition, in the process of hot spring drilling Other exploration, detection, monitoring, and maintenance equipment used also need reasonable and complete equipment to cope with various complex engineering conditions, which will affect the price of hot spring drilling. The more complex the underground geological conditions of the project site, the higher the risk of hot spring drilling, and the more means and equipment that need to be used.

For example, granite formation requires oil drilling equipment, the price per meter: about 2500;

Sedimentary rock formations can use water source geological drilling equipment, the price per meter: 1200-1500 yuan.

4. Differences in the way of using hot spring wells

The evaluation of the investment cost of hot spring drilling should also be linked to the economic value. A single form of utilization is actually a waste of geothermal resources. The same hot spring well can not only be developed into a hot spring tourist resort, a hot spring heating community, but also geothermal agriculture. , and different geothermal applications have different drilling depth and technical requirements. Therefore, the different utilization requirements of hot spring wells will also affect the investment cost of hot spring wells.

5. Comprehensive environment and market conditions

Local price levels, transportation costs, water and electricity costs, etc. are all factors that affect the price of hot spring drilling. In addition, the labor cost of drilling team construction personnel, the choice of construction personnel, and the choice of technicians and safety personnel will affect the final price of hot spring wells. .
