Well drilling talks about the general considerations for drilling a spa well

What are the common considerations for drilling hot spring wells? Hot spring drilling editorial based on years of work experience as well as reference materials to give you an analysis, the following is a brief compilation of some of the hot spring drilling, let's take a look together.

Drilling a dry well is a massive affair, and if it is not done scientifically and blindly, most places fail more than they succeed. Once there is no water, the investment is lost. In this sense, water wells are riskier and more water projects fail; it is the complexity of the technology. It is generally believed that drilling a well is "drilling a hole, down a pipe", seemingly simple, but the actual technical content is very high, involving hydrogeology, physical prospecting to find water, well technology, pump selection and other aspects of knowledge, is often not paid attention to, prone to failure, poor quality, high risk of problems. Drilling wells to find water, although very deep, but if a person has some scientific knowledge, can reduce blindness, or a great benefit.

(a) Detailed study of local hydrogeological conditions. If you do not understand the hydrogeology, do not study the hydrogeological conditions, only trust the instrument, measuring points everywhere, can only be called "blind". Hot spring drilling editors believe that the following three aspects of research and study.

1. Study the topography and geomorphology. Topography and geomorphic conditions determine groundwater recharge - runoff - drainage conditions, control the weathering of rocks, and affect the changes in groundwater abundance. In order to construct reservoirs with watershed area, boreholes also need to have recharge area for the same reason. If the lithologic conditions are the same, low-lying terrain or terrain that facilitates water collection is more likely to be a well. However, some small plains and depressions are usually occupied by muddy rocks underneath that are easily weathered and denuded, creating lowlands with poor groundwater.

2. Study the water-richness of the rocks. Hot spring drilling editor believes that rocks can be divided into three categories according to their genesis: igneous rocks, metamorphic rocks and sedimentary rocks, and then subdivided into very complex. Regardless of the genesis, the feeling when hit with a hammer, some hair "burgundy" (rigid), some hair "sheep" (flexible), some hair "brittle" (brittle), brittle rocks and limestone and other soluble rocks are more likely to become a well.

3. Study the fracture development of rocks. The fractures near the fracture zone are more developed. Fractures are more likely to form in inclined rocks than in horizontal rocks.

(2), choose the suitable local geological conditions of physical exploration to find water methods

The current physical exploration method to find water is mainly electrical exploration. Hot spring drilling small that is, electrical exploration methods are divided into artificial electric field method and self (natural) natural electric field method. Many specific methods, commonly used are compound electric method, high-density electric method, vertical electric method, four-pole symmetric profile method, joint profile method, incentive profile method, etc., each method has its own applicable conditions and interference factors, must be selected according to local conditions. After years of research on water resources, the more disturbing factors in poor waters, the stronger we use our own invented double electric measurement method to discover the water in aquifers, much better than any other methods.

Hunan Puqi Geological Exploration Equipment Research Institute, is a professional institution engaged in geological survey to find water instrument equipment research, currently has formed a partnership with Harbin Institute of Technology and jointly established the 13th Five-Year National Water Special R & D Base, with Hunan University of Science and Technology jointly established a strategic innovation and cooperation base for industry-university research, and reached a strategic partnership with the University of Algeria, Puqi new generation of physical prospecting water finder with easy to carry, operation It is easy to carry, easy to operate, automatic map formation, high accuracy, and its equipment has obtained many invention patents and software copyrights.
