Product Description
Casing Drilling Concentric is a product that finds extensive applications in the drilling industry. The primary use of this technology is in the construction of boreholes, where it facilitates the insertion of casings into the ground while also enabling drilling operations to be carried out simultaneously. The concentric design of the casing and drill pipe allows for efficient drilling through various types of soil, rock formations, and other geological materials.
One of the significant advantages of Casing Drilling Concentric is its ability to reduce the time required for drilling operations. Since the casing and drilling pipe are combined into a single unit, it eliminates the need to remove the drill pipe to insert the casing, thus saving valuable time during the drilling process. Additionally, this technology enhances the stability of the borehole by reducing the risk of collapse or deviation, ensuring safer and more efficient drilling operations.
Another distinctive feature of Casing Drilling Concentric is its adaptability to various drilling conditions, such as unconsolidated formations, fractured rock, and high-angle wells. Its design enables it to traverse diverse terrains, ensuring reliable casing placement and improving drilling efficiency. This technology also minimizes the environmental impact of drilling activities, making it a preferred choice for projects that require environmentally friendly techniques.
Overall, the Casing Drilling Concentric technology provides an innovative solution that improves the speed, safety, and efficiency of drilling operations while reducing costs and minimizing environmental risks.
Here's a general overview of how an overburden casing system works:

Applications
Water well drilling
Eccentric casing system(ODEX) is the main drilling tools in water well projects,which can keep drilling the hole and protecting it from caving in the same time.And it can significantly reduce the drilling time when drilling through the overburden.
Anchoring
Eccentric casing system(ODEX) can meet the requirements of anchoring projects better when reinforcing the slope.
Micro piling
In soil,clay and sand rock formations.eccentric casing system is the most economic and fastest in protecting the hole from
collapsing with permanent or temporary casing tubes.
collapsing with permanent or temporary casing tubes.
Other Casing Tools
Overburden casing system
Overburden casing system commonly denotes a methodology employed in specific drilling operations, such as water well drilling,anchoring, micro piling, or geothermal engineering. This technique involves the installation of a casing or pipe through successive layers of soil, rock, or other materials that lie above the target zone. The primary purpose of this casing system is to provide essential support and ensure stability throughout the drilling process. By penetrating and securing the overlying layers, it prevents cave-ins, collapses, or other undesirable occurrences, thus facilitating safer and more efficient drilling operations. This method plays a crucial role in maintaining the integrity of the borehole, protecting it from potential structural damage, and allowing for the extraction of desired resources or the implementation of various engineering applications.
Concentric casing system with ring bits
It is suitable for overburden with complex geological conditions, such as pebble, fissure, dry stone, boulder, construction backfield waste, etc. It can be drilled at any angle with high straightness.
The maximum diameter of the hole can reach 1550 mm.
Concentric casing system with blocks
1.The material of joint tools is better than casing tube and after heat treatment, the connection is reliable.
2.The casing shoe is heat-treated to extend the service life.
3.The blocks and locking kit are strengthened and have good comprehensive performance
4.Application fields: pile foundation engineering, slope support engineering
Concentric casing system with wings
It is suitable for covering layers with loose materials, such as soil, clay, weathered rock, and sand particles.
