Abstract
Description
Technical Field
[0001] This utility model relates to the field of geological exploration technology, specifically to a drill pipe device for petroleum geological exploration. Background Technology
[0002] Geological exploration is an investigation and research activity that uses various means and methods to explore and detect geology, determine suitable bearing strata, determine the foundation type based on the bearing capacity of the bearing strata, and calculate foundation parameters. It is also an investigation and research activity that discovers industrially significant mineral deposits during mineral prospecting, in order to ascertain the quality and quantity of minerals, as well as the technical conditions for mining and utilization, and to provide the mineral reserves and geological data required for mine construction design. It involves investigating and researching the geological conditions of rocks, strata, structures, minerals, hydrology, geomorphology, etc. in a certain area.
[0003] However, current geological exploration drill rod devices still have some shortcomings. According to a search, for example, a utility model patent with Chinese announcement number CN219412513U discloses a geological exploration drill rod device. This device uses a fixed rod, a sliding block, a motor box, and a base plate. The fixed rod and the sliding block, which is fixedly connected to the motor box, limit the movement. The drill rod is connected to a servo motor in the motor box and passes through a circular hole on the surface of the base plate to drill. This prevents the drill rod from deviating during drilling.
[0004] However, when the drill rod rises from the soil, the outside of the drill rod and drill bit are often covered with mud. When passing through the borehole, a large amount of mud will adhere to the borehole, which is not easy to clean. Therefore, a drill rod device for petroleum geological exploration has been proposed to solve the above problems. Utility Model Content

This prevents soil from adhering to the inner wall of the borehole when passing through it. After scraping, the second motor can be controlled to drive two striking rods to swing. The striking rods and the cleaning scraper rings are staggered, so that the soil clumps adhering to the bottom of the cleaning scraper rings can be knocked off, reducing the amount of manual cleaning work. The diameter of the three cleaning rings decreases from top to bottom, which can gradually scrape off the soil clumps and prevent excessive soil accumulation, which could damage the drill bit and drill pipe during scraping.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1-5 This embodiment of a petroleum geological exploration drill pipe device includes a base plate 1, a mounting frame 2 fixedly installed on the top of the base plate 1, a hydraulic rod 3 fixedly installed on the bottom of the mounting frame 2, a motor box 4 fixedly installed on the bottom of the hydraulic rod 3, a first motor 5 installed inside the motor box 4, a drill pipe 6 fixedly installed at the output shaft of the first motor 5, a drill bit 7 connected to the bottom of the drill pipe 6, and an auxiliary mechanism 8 provided at the bottom of the base plate 1.
[0027] Specifically, the auxiliary mechanism 8 includes a housing 801. The housing 801 is fixedly mounted on the bottom of the base plate 1. A second motor 802 is fixedly mounted on the side wall of the housing 801. A bidirectional lead screw 803 is fixedly mounted at the output of the second motor 802. A lead screw sleeve 804 is threaded onto the external part of the bidirectional lead screw 803. A rotating rod 805 is rotatably connected to the bottom wall of the housing 801. A telescopic rod 806 is fixedly mounted on the outside of the rotating rod 805. Three striking rods 807 are fixedly mounted on the outside of the rotating rod 805. A mounting post 808 is fixedly mounted on the bottom of the base plate 1. Three connecting rods 809 are fixedly mounted on the front side of the mounting post 808. A cleaning scraper ring 810 is fixedly mounted on the front side of the connecting rod 809. After exploration is completed, the hydraulic rod 3 drives the drill bit 7 and drill rod 6 to move upwards. When it passes the bottommost cleaning scraper ring 810, it will... The outermost layer of soil on the drill bit 7 is scraped off. As it continues to move upward, the two top cleaning scraper rings 810 continue to scrape, thus cleaning most of the soil and preventing soil from adhering to the inner wall of the borehole when the drill bit 7 passes through it. By controlling the second motor 802, the second motor 802 drives the bidirectional lead screw 803 to rotate, thereby causing the two lead screw sleeves 804 to move towards or away from each other. When the lead screw sleeves 804 move, they will pull the rotating rod 805 left and right, and the striking rod 807 will be driven to rotate left and right. When the striking rod 807 rotates, it can knock off the soil clods adhering to the bottom of the cleaning scraper rings 810, reducing the amount of manual cleaning work. The telescopic rod 806 is a stainless steel telescopic rod, and its size can be customized according to the application scenario. The working principle of the telescopic rod 806 is to use the relative movement between the inner and outer tubes to achieve length adjustment.
[0028] Specifically, the radii of the three cleaning scraper rings 810 increase from top to bottom, the centers of the three cleaning scraper rings 810 are all located on the same vertical line, and the diameters of the three cleaning rings 810 decrease from top to bottom. This allows for gradual scraping of the soil clods, preventing excessive soil accumulation and avoiding damage to the drill bit 7 and drill rod 6 during scraping.
[0029] Specifically, the inner bottom wall of the drill rod 6 is provided with a threaded groove, and the top of the drill bit 7 is equipped with a threaded post 9. The threaded groove and the threaded post 9 are threadedly connected. By rotating the drill bit 6, it is easy to install and remove the drill bit 6.
[0030] When implementing this procedure, please follow these steps:
[0031] 1) First, move the device to the location where the exploration borehole needs to be drilled, turn on the first motor 5 and the hydraulic rod 3, so that the drill bit 7 gradually passes through the borehole to conduct drilling exploration on the ground.
[0032] 2) After the exploration is completed, control the hydraulic rod 3 to drive the drill bit 7 and drill rod 6 to move upward. When it passes the bottom cleaning scraper ring 810, it will scrape off the outermost soil of the drill bit 7. When it continues to move upward, the top two cleaning scraper rings 810 will continue to scrape, thereby cleaning most of the soil.
[0033] 3) After cleaning is completed, control the second motor 802 to drive the two striking rods 807 to swing. The striking rods 807 and the cleaning scraper ring 810 are staggered, so the soil adhering to the bottom of the cleaning scraper ring 810 can be knocked off, reducing the amount of manual cleaning work.
[0034] In summary, this petroleum geological exploration drill pipe device, through the auxiliary mechanism 8, allows the drill pipe 6 and drill bit 7 to move upwards from the soil, gradually removing large clumps of soil adhering to their exterior through the scraping action of three cleaning scraper rings 810. This prevents soil from adhering to the inner wall of the borehole as the drill pipe 6 and drill bit 7 pass through it. After scraping, the second motor 802 can be controlled to swing two striking rods 807. The striking rods 807 and the cleaning scraper rings 810 are staggered, thus knocking off soil clumps adhering to the bottom of the cleaning scraper rings 810, reducing the amount of manual cleaning work. The diameter of the three cleaning rings 810 decreases from top to bottom, allowing for gradual scraping of soil clumps and preventing excessive soil accumulation that could damage the drill bit 7 and drill pipe 6 during the scraping process.
