Acar Kardesler - Model 2500 Mt -Geothermal Water Drilling Rig
The geothermal water drilling rig, designed for 2024, is engineered to reach depths up to 2500 meters with remarkable precision and efficiency. Mounted on either a truck or trailer, this all-in-one machine replaces the need for multiple devices by integrating the functionalities required for complex drilling operations. Primarily used for water sourcing, surveying, and mining, the rig employs rotary drilling methods to begin excavation at the most promising groundwater location. After reaching the designated depth, the drill components are retracted, and the newly formed well is secured with a casing pipe. The space between the well wall and the casing is filled with gravel to ensure stability. This rig provides a comprehensive solution with its ability to clean and develop the well through methods such as compressed air and pistons, readying it for operational use. Its capability to efficiently harness geothermal resources highlights its vital role in sustainable water management.
The drilling rig can be briefly defined as a trailer or truck mounted device.
Work done by separate machines on large drilling rigs is combined in drilling machines and can be done with a single machine. Rotary drilling rigs are mostly used for water, surveying and mining purposes. Drilling starts from the point determined to be the most productive in terms of groundwater.
Then, when the target depth is reached, the drill bit and drill pipe are removed, the well is protected by a casing pipe with a diameter smaller than the diameter of the drill, and the gap between the well wall and this casing is closed. drilling filled with gravel
Then the well is cleaned and developed (with compressed air, piston, etc.) and made ready for use.
Geothermal Water Drilling Machines
Geothermal water drilling rigs are the extraction of geothermal resources to the earth by methods similar to the extraction of oil or natural gas. Before starting geothermal drilling, it is necessary to measure the carbon dioxide ratio of the soil to be drilled, electrical and magnetic studies, seismic research studies.
While drilling in geothermal wells, the protection pipe should be designed with the measurements to be made since temperature and corrosion may cause expansion and the presence of precipitating fluids will affect the drilling. In order to make geothermal drilling more efficient, cooling tower, Top Drive for the continuity of manoeuvre in jamming situations, solids separators can be used for devices such as sand and silt separator.
Geothermal Source
Geothermal resources are renewable energy sources in the form of hot water, water vapour or gas containing chemicals arising from the heat deep in the earth. Factors such as the source of heat in the earth's crust, the fluid that allows it to be transported above the ground, and the circulation of water constitute the characteristics of the geothermal resource.
It is a type of energy that works with the system of converting the hot water vapour extracted from the underground into electrical energy and then directing the cooled vapour back to the underground. Geothermal drilling is carried out in long periods of time and involves more difficulties compared to other drilling, as more rocks are tried to be drilled.
Geothermal Energy Usage Areas
- Electricity generation
- In central heating systems of houses, streets, greenhouses
- Food drying
- For health purposes in hot springs
- In the production of chemicals and minerals
- Mineral water consumption
Factors Affecting the Cost of Geothermal Water Drilling Rigs
The cost of geothermal drilling rigs is difficult to determine due to unplanned problems or operations during drilling. Due to the fact that the rocks are harder and more abundant, the number of drills used is higher, additional mud and cement costs, the drilling rig has a larger diameter, which can cause 2-3 times the cost of normal oil well costs.
