ST 350 Water Well Drilling Rig Advantages
This is a high efficiency and multi-functional down the hole water well drilling equipment, It can be used to drill water well, agrecultural irrigation well, geothermal well and other type well holes. It is sepcial suitable for mountain area and rock stratum water sourcing project.
system. The brand diesel is protected by 2 levels air filtration systems and also can directly use the clean air from the air compressor.
The pneumatic drilling rig is multifunction, with different configurations suitable for different geologies.Accept customization,any good ideas please contact us, our engineers will help you get what you want, we can also put the platform on a truck mounted chassis
Courtyard Drilling Attentions
1. Consider whether the well depth is reasonable
We should first investigate whether there are cables, sewers and other facilities under the ground, and avoid unnecessary damage.
2. Convenience, health and other issues should be considered.
After drilling the well, find some charcoal and throw it into the well with a bag and press it at the bottom of the well to absorb foreign toxins. After having water, you can put a few small fish down, which is a good way to test the safety of water quality.
3. The well should not be too deep. It should be above the ground and should be blocked with bricks and stones. It is better to have a cover, so as to prevent dirt from falling in, make people feel safer and avoid unnecessary dangers.
Due to different geological structures in different places, different geological structures are often encountered in the drilling process of drilling machine. In order to achieve good drilling effect, it is necessary to understand the drilling methods of different geological layers
For example, when drilling gypsum layer, the drilling fluid shall be pretested first. Calcium ions can be removed by adding anti gypsum treatment agents such as soda ash calcium removal and viscosity reducer. At the same time, viscosity reducer with strong calcium resistance shall be used to control viscosity cutting, and materials such as fluid loss reducer and anti sloughing agent shall be supplemented to maintain the stability of the performance of the drilling fluid, so as to improve the anti gypsum pollution ability of the drilling fluid in the drilling machine
In case of quicksand formation, the viscosity of drilling fluid must be increased and the bentonite content in the drilling fluid must be increased. Generally, it is required to be greater than 10%. A single seal is added to enhance the wall building property of the drilling fluid. In engineering, by appropriately reducing the displacement and reducing the erosion of convective sand layer, the well section must be closed with thick mud with viscosity greater than 80s before tripping out, so as to ensure the smooth running of drilling equipment and electric logging casing
