What kind of research should be done before drilling a well in a spa?

One of the most important aspects of spa project development is spa drilling, so in the early stages of spa construction it is necessary to find a spa drilling company with good quality, good service and good after-sales service to drill the well. In order to ensure the successful completion of the drilling, relevant research work needs to be carried out before drilling. So, what kind of research work should be done before the spa drilling?

1. Understanding the resource status

Not all places are suitable for spa drilling. Hot spring drilling requires drilling for hot spring water from underground, and the underground geology is complex, so choosing a reliable hot spring drilling can provide advance knowledge of the net flow and discharge conditions of geothermal water recharge at the project site, as well as grasp its underground rock strata. Hot spring drilling needs to find four major elements, namely: heat source, recharge, channel and overburden. To do a detailed spa survey in the early stage is to find the best location for these four elements and then conduct spa drilling, which makes it easier to successfully drill a well.

Based on the formation factors, rocks can be divided into three categories: igneous, metamorphic and sedimentary rocks. Due to the different formation factors of rocks, the sensation of hammering will vary, including rigid sound, flexible sound and brittle sound. On the other hand, brittle rocks and soluble rocks such as limestone are more likely to form wells. Therefore, before drilling a well in a spa center, you can investigate the overburden of the original rocks and drill a well in an area where the overburden is very strong. In general: close to the fault fracture zone is a good place to drill a well.

2. Conduct a detailed survey and physical exploration

Before drilling a well in a hot spring, you need to conduct a detailed geothermal resource survey so that you can understand in detail the geological terrain geothermal resources of the project. Physical exploration is the most important aspect of geothermal resource survey, and using appropriate physical exploration methods can provide a more detailed understanding of whether the project is suitable for drilling and provide a reference basis for drilling design. In general, the commonly used method for finding water is electrical exploration, with this method, it can be specifically divided into high-density electrical survey methods, duplex electrical survey method, four-level symmetric profile method, laser method and vertical electrical survey method, etc. As the methods are different, the applicable conditions and interference factors are also different, and need to be adapted to the local conditions.

In short, all the above work should be done before the spa drilling, only then we can improve the chances of successful spa drilling, which is also the preparation work before the spa drilling to better determine the location of the spa drilling. Only when the exact location of the hot spring drilling is determined can we proceed to the next step, thus ensuring the smooth implementation and completion of the drilling.
