The natural surface mounted reamer has the following applications in the field of geological exploration:
1. Drilling and reaming: In geological exploration, drilling operations are carried out, followed by the use of reamers to enlarge the aperture. The natural surface mounted reamer utilizes natural diamonds embedded on its surface. With the high hardness and strong wear resistance of diamonds, it can effectively expand the diameter of drilled holes, creating better conditions for subsequent geological exploration, sampling, and other work. For example, in exploration drilling of metal mines, non-metal mines, coalfields, etc., it can perform reaming operations in rocks of various hardness.
2. Crushing strong abrasive formations: For some hard and abrasive formations, ordinary hole openers are prone to wear, while natural surface mounted hole openers have good wear resistance and impact resistance due to the natural diamond inlay, which can maintain good working performance, extend service life, improve drilling efficiency, and reduce exploration costs when crushing strong abrasive formations. For example, when drilling into sandstone formations with high quartz content or metamorphic rock formations containing a large amount of hard minerals, natural surface mounted reamers can more effectively break rocks and reduce the frequency of reaming tool replacement.
3. Ensure the quality of the hole wall: During the process of expanding the hole, the natural surface mounted reamer can cut the rock more evenly, making the hole wall smoother and the hole diameter more uniform. This helps to improve the accuracy of subsequent geological surveys, logging, and other work, while also preventing the collapse of the borehole wall, ensuring the stability of the borehole, and providing assurance for obtaining high-quality geological data. For example, in the exploration of groundwater resources, smooth and uniform pore walls are beneficial for the seepage of groundwater and the placement of measuring instruments.
4. Auxiliary directional drilling: In directional drilling, natural surface mounted hole openers can be used in conjunction with other directional equipment. By correctly controlling the direction and size of the hole enlargement, it helps to achieve directional detection of rock and soil along the predetermined wire trajectory, improve directional accuracy, and provide support for correct detection under complex geological conditions. For example, in the geological guidance pre drilling of shale gas horizontal wells, it can assist the drill bit in correctly drilling along the designed horizontal direction, improving the efficiency of shale gas extraction.
