Water drilling is the drilling of a well with air or mud circulation in accordance with the geological structure of the ground. After the well is drilled, a project is made in accordance with the hydrological characteristics of the drilled well. Sheath piping of the well is made with special drill pipes.
The logic of water drilling; It is the process of reaching the water at a certain depth of the underground and pulling it with a pump. It is important that the well is not destroyed during the water withdrawal process. Necessary measures must be taken for this. The quality level of the well varies according to the pipe diameter used, the type of the pipe, the suitability of the project, the thickness of the gravel envelope and the applied water drilling techniques.
HOW IS WATER DRILLING DONE?
The water drilling technique used in hard rocky environments and the water drilling technique used in soft soils are different from each other.
Water Drilling Techniques:
• Drilling is done using mud circulation in soft soils.
• In rocky and harsh environments, drilling is done with air circulation.
Drilling Stages:
• After the water survey, drilling should be done from the place that is determined to be the most efficient in terms of groundwater.
• When the desired depth is reached after the work, the drill bit and pipes are taken out and the well is taken into a casing with the help of a small diameter casing pipe.
• The space between the well wall and the casing pipe is filled with the washed and sieved drilling gravel.
• The drilled well is cleaned and becomes ready for use with compressed air and pistoning.
