Dry Drill Set Manufacturer

Dry drilling is a special drilling method that does not require the use of liquid drilling fluid for shock cooling and cleaning, but rather discharges rock cuttings from the wellhead through air pressure. Dry drilling technology is suitable for some special geological conditions and engineering needs, and has the following characteristics.

Dry drilling can effectively reduce drilling costs. Since liquid drilling fluid is not required, it can avoid the preparation and treatment of drilling fluid. At the same time, as there is no need for impact cooling, it can also reduce the corrosion and dissolution of soluble rocks such as calcium carbonate, extend the service life of drill bits, reduce the frequency of drill replacement and maintenance costs.

Secondly, dry drilling can avoid the problem of water shortage. In some areas, especially arid or waterless areas, water resources are very limited, and the use of liquid drilling fluids requires a large amount of clean water supply, which brings difficulties to drilling operations. Dry drilling, on the other hand, is completely independent of water resources, saving a lot of water resources, and can be used for drilling operations in areas without water or with water scarcity.

Thirdly, dry drilling can reduce the environmental pollution caused by drilling. Traditional liquid drilling fluids often contain toxic and harmful substances, such as heavy metals and volatile organic compounds, which can easily cause environmental pollution and damage to ecosystems during their use and treatment. Dry drilling does not require the use of liquid drilling fluid, which can reduce the discharge of these toxic and harmful substances and the pollution to the environment.

In addition, dry drilling also has some other characteristics and applications. For example, dry drilling can be used for deep core sampling. Liquid drilling fluid can easily cause core distortion under high temperature and pressure conditions, making it difficult to maintain its original state and reducing the accuracy of rock formation information. Dry drilling, due to the exclusion of liquid drilling fluid, can better maintain the original rock core, improve the quality and accuracy of core extraction, and is of great significance for geological exploration and mineral resource evaluation.

In addition, dry drilling can also be used for special environmental conditions and engineering needs. For example, dry drilling can be applied to glacier detection and glacier rock sampling. In extremely cold regions, the solidified liquid drilling fluid from frozen formations may be difficult to melt, affecting the progress of drilling operations. Dry drilling can perform drilling operations in low-temperature environments, avoiding this problem, and can obtain core samples of glaciers, providing important basis for glaciological research.
