Problems solved by technology
[0003] During the drilling process, when the formation to be explored is deep, the deviation of the drilling direction is too large, which will lead to failure to reach the target rock formation, resulting in exploration failure. In order to accurately explore the target formation, it is necessary to strictly control the deviation of the drilling direction. When the drilling rig is drilling Vibration will be generated during the process, and the vibration will cause the hole wall to collapse, causing the drill bit to be buried in the ground and cannot be taken out, resulting in delays in exploration time and property losses

Embodiment 1
[0044] see Figure 1-4 , a positioning and guiding device for geological drilling, comprising an outer casing 1, characterized in that: the upper end of the outer casing 1 is provided with an outer casing 3, the inner casing of the outer casing 1 is slidably provided with an inner casing 4, and the inner casing The upper end of the 4 is provided with an inner protective plate 41 corresponding to the position of the outer protective plate 3, and the upper end of the inner casing 4 is provided with a drilling bucket 42, which is a funnel-shaped structure with an upward opening. The inner protective plate 41 and the drilling bucket 42 There is a reserved section between them, and the funnel-shaped drilling bucket 42 is conducive to the entry of the drill bit, which effectively reduces the deviation caused by the impact on the device when the drill bit is installed. The reserved section is easy to clean and effectively avoids soil accumulation.

The invention discloses a positioning and guiding device for geological drilling, and belongs to the technical field of positioning and guiding. According to the scheme, a plurality of preformed holes are formed in an outer protective disc, stabilizer bars are inserted into the ground through the preformed holes, the stability and shock resistance of the device are improved, an inner protective barrel is arranged in an outer protective barrel, vibration generated by the device is reduced, and the service life of the device is prolonged. Meanwhile, the fixing rod is inserted into the reinforcing rod and extrudes and punctures the reinforcing rod to move downwards, so that the puncturing rod penetrates through the sliding way to penetrate into the ground, the contact area is further increased, meanwhile, a soil adhesive is poured into the fixing rod, the soil adhesive enters surrounding soil through seepage holes of the puncturing rod, the surrounding soil is solidified, and the stability is further improved.
Description
technical field [0001] The invention relates to the technical field of positioning and guiding, and more specifically, relates to a positioning and guiding device for geological drilling. Background technique [0002] Drilling is an important technical means in geological exploration work. Drilling rigs are used to drill down from the surface of the earth to form cylindrical boreholes in the strata to identify and divide the strata. Cores, ore samples, and soil samples can be obtained from different depths in the borehole for analysis and research, to determine the physical and mechanical properties and indicators of rock and soil layers, and to provide design needs. [0003] During the drilling process, when the formation to be explored is deep, the deviation of the drilling direction is too large, which will lead to failure to reach the target rock formation, resulting in exploration failure. In order to accurately explore the target formation, it is necessary to strictly ...
