What are the uses of natural surface reaming shell
The natural surface reaming shell has the following main uses:
1. Geological drilling field
Correction of borehole wall: During the drilling process, the borehole wall may experience unevenness, collapse, and other issues. The natural surface reaming shell can adjust the hole wall through rotation and cutting, making it smooth and regular, ensuring the quality and stability of the boreho
The natural surface mounted reamer has the following main uses:
1. Geological drilling field
Correction of borehole wall: During the drilling process, the borehole wall may experience unevenness, collapse, and other issues. The natural surface reaming shell can adjust the hole wall through rotation and cutting, making it smooth and regular, ensuring the quality and stability of the borehole, and providing good conditions for subsequent logging, casing and other operations.
Maintain aperture: As the drilling depth increases, the borehole may experience a reduction in diameter. The natural surface reaming shell can appropriately expand the diameter of the hole wall during drilling, maintain the diameter of the borehole in accordance with design requirements, and prevent the drilling tool from getting stuck or unable to be inserted into subsequent tools and equipment due to a decrease in aperture.
Improving the quality of core drilling: During core drilling, a natural surface reaming shell can enlarge the hole wall on the outside of the core drill bit, reducing friction and collision between the core and the hole wall, thereby improving the recovery rate and integrity of the core, and providing more accurate and complete core samples for geological analysis.
2. Non excavation construction field
Pipeline laying and hole expansion: In non excavation pipeline laying projects, such as horizontal directional drilling construction, a guide hole needs to be drilled first, and then a hole expander is used to gradually expand the guide hole to accommodate the diameter of the pipeline to be laid. The natural surface reaming shell, with its natural diamond surface mounted cutting edge, can effectively cut and crush rock and soil, achieve the purpose of enlarging holes, and create conditions for the pullback laying of pipelines.
Drilling through obstacles: During non excavation construction, various obstacles such as rocks, tree roots, old pipelines, etc. may be encountered. The natural surface reaming shell can break and cut obstacles through its powerful cutting ability, expand the diameter of the borehole, and enable pipelines to smoothly pass through obstacles.
3. Mining and extraction field
Tunnel expansion excavation: In mining, it is necessary to expand the tunnel to meet transportation, ventilation, drainage and other needs. The natural surface reaming shell can be installed on the drilling truck to perform reaming operations on the walls and top of the tunnel, increasing the cross-sectional size of the tunnel and providing guarantees for the production and safety of the mine.
Blast hole enlargement: In blasting operations, it is sometimes necessary to enlarge the diameter of the blast hole to increase the loading capacity and improve the blasting effect. natural surface reaming shell can be used for borehole enlargement operations, enabling the diameter of the borehole to meet the design requirements, thereby better controlling the energy release and rock fragmentation effect of blasting.
