[0022] In the present invention, descriptions such as "first", "second", etc. are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features.

[0023] Embodiment 1:

[0024] In a first aspect, the present invention provides a hydrogeological exploration device, which is used in hydrogeological exploration operations. As shown in Figure 1 Figure 1, it includes a drill pipe 1, a drill bit 2 provided at the bottom of the drill pipe 1, and a hydrogeological information acquisition system 3; the drill bit 2 drills into the formation under the drive of the drill pipe 1 to form a borehole 10, and the hydrogeological information acquisition system 3 is used to synchronously collect hydrogeological parameters in the formation during the drilling process; the hydrogeological information acquisition system 3 includes a pumping mechanism 31 and a first detection mechanism 32. The pumping mechanism 31 is provided on the drill pipe 1 and is used to synchronously extract water in the formation during the drilling process, and the first detection mechanism 32 is used to detect the water sample extracted by the pumping mechanism 31.

[0025] The hydrogeological exploration device drills into the formation structure through the rotation of the drill pipe 1 and the drill bit 2 to form a borehole 10, and synchronously extracts the water in the drilled formation structure and collects the hydrogeological information in real time during the drilling process of the drill pipe 1, ensuring the accuracy and timeliness of the collection of the water temperature information in the formation; it can conduct a pumping test synchronously, more accurately evaluate the groundwater hydrogeological conditions, accurately obtain hydrogeological information such as the thickness and location of the aquifer, and the initial water level, etc., provide accurate data support for calculating the groundwater buoyancy in the basic engineering design, and reduce the engineering cost; improve the quality and comprehensive efficiency of drilling.

[0026] Optionally, the first detection mechanism 32 includes a first pressure sensor 321, a first temperature sensor 322, and a water quality sensor 323; the first pressure sensor 321 is provided on the drill bit 2 and is used to monitor the water pressure in the formation, the first temperature sensor 322 is provided at one end of the drill pipe 1 close to the drill bit 2 and is used to monitor the water temperature in the formation, and the water quality sensor 323 is provided at one end of the drill pipe 1 close to the drill bit 2 and is used to detect the water quality in the formation.

[0027] During use, the pumping mechanism 31 pumps water in the formation into the drill pipe 1, and the first detection mechanism 32 monitors in real time the hydrological information in the corresponding formation pumped into the drill pipe 1. The setting of the first detection mechanism 32 can comprehensively detect the water pressure, hydrology and water quality of the water in the formation. Among them, the first temperature sensor 322 is arranged away from the drill bit 2 to avoid the heat generated by the drill bit 2 during drilling from affecting the temperature test of the water in the formation, ensuring the accuracy of the water temperature test in the formation.

[0028] In another embodiment, a plurality of first pressure sensors 321 are provided. The first pressure sensors 321 are arranged at intervals from one end of the drill pipe 1 close to the drill bit 2 towards the end away from the drill bit 2. The arrangement of the plurality of pressure sensors can more comprehensively detect the distribution law of water pressure in the formation corresponding to different depths, and at the same time can monitor the local pressure in the borehole 10 in real time to prevent the collapse of the borehole wall of the borehole 10 from affecting the drilling.

[0029] Optionally, stabilizers 4 are arranged at intervals on the outer wall of the drill pipe 1, and the stabilizers 4 are in contact with the inner wall of the borehole 10. The stabilizers 4 are used to maintain the stability of the drill pipe 1 during drilling, reduce the swing and vibration of the drill pipe 1, and prevent the collapse of the hole wall of the formed borehole 10. The stabilizer 4 includes a telescopic bracket 41 arranged on the outer wall of the drill pipe 1 and a roller 42 arranged at one end of the telescopic bracket 41 away from the drill pipe 1. The roller 42 is in contact with the hole wall of the borehole 10. When the drill pipe 1 moves in the borehole 10, the roller 42 rolls, avoiding jamming of the stabilizer 4.

[0030] For example, in some embodiments, the telescopic bracket 41 at least includes two inclined feet. One end of the feet is connected to the outer wall of the drill pipe 1, and the other end is connected to the roller 42. The end of the feet away from the outer wall of the drill pipe 1 is radially distributed towards the end close to the outer wall of the drill pipe 1, and the roller 42 is arranged at the end of the feet away from the outer wall of the drill pipe 1. Further, the telescopic bracket 41 is a telescopic rod, and the feet on the same telescopic bracket 41 are synchronously telescoped to adjust the position of the roller 42 relative to the outer wall of the drill pipe 1, so that the stabilizer 4 can be applied to different diameters of the borehole 10 and formation conditions, ensuring the close contact between the stabilizer 4 and the hole wall. Optionally, the roller 42 is a shock-absorbing roller 42, further ensuring the stability of the movement of the stabilizer 4.

[0031] In some embodiments, the stabilizers 4 arranged on the same cross-section of the drill pipe 1 are evenly distributed circumferentially along the drill pipe 1. Further, the stabilizers 4 arranged axially along the drill pipe 1 are arranged with a dislocation therebetween to ensure that the stabilizers 4 provide comprehensive support for the drill pipe 1, thereby further improving the stability of the movement of the drill pipe 1. The arrangement of the stabilizers 4 ensures the stability of the drill pipe 1 during the drilling process, reduces the swing or vibration of the drill pipe 1, and avoids the collapse of the hole wall caused by the instability of the drill pipe 1; it can effectively reduce the disturbance to the formation, reduce the risk of hole wall collapse, and improve the drilling quality and the stability of the borehole 10.

[0032] Optionally, the drill bit 2 includes a drill bit body 21 connected to the drill pipe 1 and vanes 22 provided at one end of the drill bit body 21 away from the drill pipe 1; the vanes 22 are evenly distributed along the end of the drill bit body 21. The number of the vanes 22 is at least 3; in some embodiments, one end of the drill bit body 21 away from the drill pipe 1 is in a conical structure, and the vanes 22 are distributed on the surface of the conical structure.

[0033] At least part of the vanes 22 are prepared from a high-strength wear-resistant alloy material; for example, the high-strength wear-resistant alloy material can be provided in the edge area of the vanes 22, or the vanes 22 are entirely made of the high-strength wear-resistant alloy material. During use, the vanes 22 of the drill bit 2 first contact the formation structure and drill the formation structure. The high-strength wear-resistant alloy material has properties such as high strength and wear resistance, which improves the wear resistance and cutting performance of the drill bit 2 and ensures the drilling efficiency; the high-strength wear-resistant alloy material includes one or more of a cemented carbide material containing tungsten and cobalt elements, a diamond composite sheet, high-speed steel, or a tungsten-cobalt alloy.

[0034] Optionally, the drill pipe 1 is provided with a hollow channel 11 arranged axially thereon, and the hollow channel 11 is used for transmitting drilling flushing fluid and / or the data transmission line of the hydrogeological information acquisition system 3; the drill pipe 1 includes a plurality of interconnected drill pipe units, and the drill pipe units are all hollow columnar structures, and the hollow channel 11 is formed after the drill pipe units are interconnected through a matching structure.

[0035] In the present invention, the structure of the drill pipe 1 is decomposed into a number of interconnected drill pipe units. During use, the length of the drill pipe 1 can be adjusted according to specific requirements, improving the applicability of the drill pipe 1. The smaller-sized drill pipe units are convenient for storage and transportation and are more suitable for the exploration environment. In some embodiments, the drill pipe units are connected by a threaded mating connection structure, which includes a first connection structure and a second connection structure respectively provided at both ends of the drill pipe unit. The first connection structure and the second connection structure are mutually mating threaded structures, and at least one of the surfaces of the first connection structure and the second connection structure provided on the same drill pipe unit is coated with a sealing layer. The setting of the sealing layer further ensures the connection firmness and sealing performance between the drill pipe units; the setting of the first connection structure and the second connection structure standardizes the structure of the drill pipe units. When in use, different ends of two interconnected drill pipe units are connected to each other through the first connection unit and the second connection unit, thus avoiding the occurrence of the situation where different drill pipe units cannot be assembled. And during use, if a drill pipe unit is damaged, it is convenient to quickly replace, improving the drilling efficiency.

[0036] The drill pipe 1 is prepared from one or several of high alloy steel, aluminum alloy, titanium alloy, carbon fiber composite material or rare earth microalloyed steel, so as to endow the structure of the drill pipe 1 of the present invention with better strength and corrosion resistance. In some embodiments, the first connection structure is an external thread structure, and the second connection structure is an internal thread structure that mates with the first connection structure; in other embodiments, the first connection structure can be an internal thread structure, and the second connection structure is an external thread that mates with the first connection structure.

[0037] Optionally, the hydrogeological exploration device further includes a flushing mechanism, which includes a delivery pipe for delivering flushing liquid into the drill pipe 1 and a flushing liquid supply member connected to the delivery pipe; the drill bit 2 is provided with a water spray port that communicates with the hollow channel 11, and the water spray port is used for spraying high-pressure flushing liquid to assist in rock fragmentation and bottom-hole rock debris cleaning.

[0038] Optionally, the hydrogeological exploration device further includes an intelligent control system 5; the intelligent control system 5 is electrically connected to the drill pipe 1, the hydrogeological information acquisition system 3, and the flushing mechanism respectively. The intelligent control system 5 is respectively used to perform real-time control on the drilling state of the drill pipe 1 according to a preset algorithm and program, regulate the flow rate of the flushing liquid of the flushing mechanism, and receive and process the data of the hydrogeological information acquisition system 3. Through the intelligent control of the flushing mechanism by the intelligent control system 5, it is possible to follow the real-time situation during the drilling process and perform real-time control on the flushing mechanism, ensuring real-time and effective cleaning of the drill pipe 1 while precisely controlling the amount of flushing liquid used and avoiding waste of the flushing liquid. The intelligent control system 5 analyzes and processes the collected hydrogeological information and displays it in the form of an intuitive chart for output, so as to timely understand the hydrogeological conditions of the formation and provide a basis for subsequent drilling decisions. Through the real-time regulation of the drilling process by the intelligent control system 5, the drilling parameters are automatically adjusted according to the formation conditions, improving the drilling efficiency, reducing the wear of the drill bit 2, and reducing the drilling cost.

[0039] Optionally, the hydrogeological information acquisition system 3 further includes a data reader 6 connected between the first detection mechanism 32 and the intelligent control system 5, and the data reader 6 transmits the information collected by the first detection mechanism 32 to the intelligent control system 5.

[0040] In some embodiments, the pumping mechanism 31 includes a water pump disposed at the bottom of the drill pipe 1 and a driving member disposed outside the drill hole 10 for driving the water pump, and the driving member is electrically connected to the intelligent control system 5; during use, the driving member is controlled by the intelligent control system 5, and the driving member is turned on to drive the water pump to pump the water in the formation into the drill pipe 1. During the drilling process, the pumping mechanism 31 performs segmented pumping according to different formation depths or aquifers, ensuring comprehensive collection of the hydrogeological information of the groundwater while improving the collection efficiency; when drilling into the first aquifer, an initial pumping test is carried out, and data such as the water level drop, recovery situation, and pumping volume are recorded. Then, as the drilling continues, when encountering the next aquifer or a region with a large formation change, a pumping test is carried out again. Through the segmented pumping test, the hydrogeological characteristics of different depth formations can be understood in detail, such as the variation of parameters such as the permeability coefficient, transmissivity coefficient, and storage coefficient of the aquifer, thereby meeting the requirements of high-precision hydrogeological investigation and research and being able to obtain the hydrogeological information of the formation in real time and comprehensively.

[0041] Optionally, the intelligent control system 5 includes a second detection mechanism for real-time monitoring of the drilling state of the drill pipe 1 and transmitting the detection information to the intelligent control system 5. The second detection mechanism includes a second pressure sensor disposed on the drill bit 2 for detecting the drilling pressure of the drill bit 2. The intelligent control system 5 adjusts the drilling state of the drill pipe 1 according to the detection information transmitted by the second pressure sensor.

[0042] In a second aspect, an embodiment of the present invention provides a hydrogeological exploration method using the hydrogeological exploration device as described above, including the steps of: the rotation of the drill pipe 1 drives the rotation of the drill bit 2, and the drill bit 2 contacts the formation to drill the formation, forming a borehole 10; during the drilling process, the stabilizer 4 on the drill pipe 1 contacts the wall of the borehole 10; during the process of the drill pipe 1 drilling in the borehole 10, the hydrogeological information acquisition system 3 monitors the hydrogeological information in the formation in real time.

By injecting clean water into the hole and using the circulation of the flushing fluid to thoroughly remove the cuttings and mud in the hole. Then, a protection device is installed at the hole opening to prevent sundries from entering the hole and affecting subsequent hydrogeological observations and tests.

[0044] The drilling process of the drill pipe 1 specifically includes the steps of: starting the device; slowly drilling the drill bit 2 from the ground 20 into the formation. In the initial stage of drilling, a low rotation speed and small pressure method are used for drilling to allow the drill bit 2 to gradually adapt to the formation conditions. As the drilling depth increases, according to the formation information fed back by the hydrogeological information acquisition system 3, the rotation speed, drilling pressure and flushing fluid flow rate of the drill pipe 1 are adjusted in a timely manner; when encountering a hard formation, the intelligent control system 5 adjusts the drilling pressure and the rotation speed of the drill pipe 1 to ensure smooth drilling while preventing excessive wear of the drill bit 2 and collapse of the hole wall; at the same time, the flushing fluid flow rate is adjusted accordingly to better cool the drill bit 2 and carry the cuttings. During the drilling process, the stabilizer 4 always remains in a working state to ensure the stability of the drill pipe 1. If the formation is unstable or there are signs of collapse, the intelligent control system 5 controls and adjusts the drilling state of the drill pipe 1 and the flow rate of the cleaning fluid according to the acquisition information sent by the first detection mechanism 32 to stabilize the hole wall.
