How much is it to have a look at the hot springs?

In recent years, the development and utilization of hot springs in China is in full swing, and various hot spring resources have mushroomed all over the country. As a very distinctive tourism resource, it can not only carry out diversified business such as hot spring bathing, hot spring medical treatment, hot spring sports and hot spring beauty, but also provide residential heating and domestic hot water. In addition, the remaining water can also be used for agricultural planting and flower planting. The economic value of hot springs is so high that many investors and developers have a strong interest.

As we all know, hot springs are a kind of geothermal mineral resources buried underground. In order to add hot spring products to tourism projects, in addition to various cultural tourism planning and planning and design, the most important thing is to have real hot springs. The natural exposed hot springs have been basically developed, so we can only dig wells and springs. So, how much does it cost to drill a hot spring well Next, let Bian Xiao explain it to you.

How much does it cost to drill a hot spring well?

Geothermal (hot spring) exploration cost

Before drilling a hot spring well, it is first necessary to determine whether there are hot springs. Is it possible to determine that there are hot springs in this place as long as there are hot springs exposed nearby or hot spring wells are drilled? It can only be said that it is possible, because the formation of hot springs is related to geological structures, and usually two resource forms are formed. One is a layered hot field, similar to an oil field. If you can play hot springs nearby, you will be close to it. Of course there are exceptions. If it is a honeycomb thermal field, it is not good to just drill wells on the "ridge"; The other is strip heat storage, similar to a river ditch or pond. The water supply is slow, so the probability of hitting a rock without water is much greater. Is that layered or banded? Where can I drill without "stepping on thunder"?

Many people will say, who can know the underground situation? Isn't this equivalent to gambling on luck? Actually, it's not without traces. As early as after liberation, China has carried out large-scale exploration of mineral resources, and the situation of solid minerals and metal minerals is very clear and the technical level is very mature. In order to find out the geothermal (hot spring) situation, it is necessary to use the theory and exploration technology in geological survey, geophysics, geochemistry, geothermal drilling and other model fields to calculate and calculate the dynamic balance of fluid, so as to judge the location and depth of geothermal well drilling, as well as the water temperature and water quantity.

Hot spring exploration in the market includes simple geophysical exploration, ranging from10-200,000, and all-round hot spring exploration, which comprehensively evaluates the development and utilization of geothermal resources and provides solutions. According to different regional geological conditions, the price range is between 400-654.38+0 million.

After the drilling cost is investigated, the drilling construction project can be started according to the drilling design model. The drilling project is the most expensive part of the whole hot spring well. The price of drilling construction project is determined by comprehensive factors such as geographical location, geological conditions, resources, drilling depth designed by the project, industry market, selection of drilling construction team, selection of drilling equipment, and arrival mode of hot spring wells.

1. Influence of geological conditions on hot spring wells

Geological conditions have a great influence on drilling. The more complicated the underground conditions, the higher the risk of hot spring drilling, and the more means and equipment are needed. At the same time, different underground rock properties and strata have different requirements for technology and equipment. Therefore, different underground geological conditions will also affect the price of hot spring drilling. For example, regardless of resource factors, the price of drilling a 2000-meter-deep hot spring well is different from that of drilling a 5000-meter-deep hot spring well. The price of drilling a 2000-meter-deep hot spring well ranges from1000 to 2500 yuan/meter, and the price of drilling a 5000-meter-deep geothermal well ranges from 4000- 1000 yuan/meter. The deeper you drill, the more expensive it is, because the deeper you drill, the higher the requirements for the overall equipment and the greater the difficulty of drilling, so the higher the price.

2. Selection of construction team

The choice of construction team itself will affect the price of drilling, which is related to the local market where the construction team is located and the type and level of the construction team. A good drilling construction team should not only pay attention to construction, but also control the construction quality, construction progress and safety of the whole drilling process, and at the same time monitor the data in real time to observe whether the rock properties in each stage are consistent with the previous exploration and prediction, and whether the construction progress, methods and equipment selection need to be adjusted. 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 stratigraphic structures have different requirements for technology and equipment, and different equipment and drilling consumables have different loss prices, which also constitutes the price difference of hot spring wells. In addition, other exploration, detection, monitoring and maintenance equipment used in hot spring drilling also need reasonable and perfect equipment to deal with various complex engineering conditions, which will affect the price of hot spring drilling. The more complicated the underground geological conditions of the project site, the higher the risk of hot spring drilling, and the more means and equipment are needed. For example, granite strata need oil drilling equipment, and the price per meter is around 2500; For sedimentary rocks, water source geological drilling equipment can be selected, and the price per meter is 1200- 1500 yuan.

4. Differences in utilization modes of hot spring wells

Evaluating 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 hot spring tourist resort and hot spring heating area, but also be developed into geothermal agriculture. Different geothermal applications have different requirements for drilling depth and technology. Therefore, different utilization requirements of hot spring wells will also affect the investment cost of hot spring wells.

5. Comprehensive environmental and market conditions

The local price level, transportation costs, utilities and so on are all factors that affect the price of hot spring drilling. In addition, the labor cost of drilling crew construction personnel, the choice of construction personnel, technicians and safety personnel will all affect the formation of the final price of hot spring wells.
