[0027] The present invention has the following advantages:

[0028] 1. The integrated drilling and water level measurement device provided by the present invention has a cavity arranged inside the drilling rig, the cavity is connected with a water-permeable hole arranged on the outer surface of the drilling rig, the measuring part of the water level measuring piece is arranged in the cavity, an air bag is also arranged in the cavity, the drilling rig is provided with an air intake channel connecting the air bag with the outside, the air bag is suitable for being connected with the air intake and exhaust equipment of the outside through the air intake channel, the signal terminal is communicatively connected with the water level measuring piece, and can obtain the water level information measured by the measuring part. The measuring part of the water level measuring device is arranged in the cavity inside the drilling rig. When the drilling rig drills into the formation, if there is a water source in the formation, the water can be poured into the cavity through the water permeable holes opened on the outer surface of the drilling rig. After the measuring part senses the water, it transmits the signal to the signal terminal. Combined with the installation position of the measuring part on the drilling rig and the drilling depth of the drilling rig, the water level information of the drilling rig is obtained. The airbag of the inflation component is arranged in the cavity. The airbag can be connected with the external air intake and exhaust equipment and change its volume under the action of the air intake and exhaust equipment. When the water permeable hole is blocked by mud and gravel in a harsh and complex formation environment, the airbag discharges the mud and gravel out of the water permeable hole through repeated inflation and deflation steps, so that the water can be smoothly poured into the cavity. In addition, the airbag can discharge the excess gas in the cavity through repeated inflation and deflation steps, which is beneficial to the filling of water into the cavity and improves the measurement accuracy of the water pressure measuring device. Compared with the traditional technology in which drilling and water level measurement are carried out in steps, the integrated drilling and water level measurement device provided by the present invention can measure the water level height without pulling out the drill rig after drilling. The inflation component can exhaust the air in the drilling rig cavity, allowing the water body to completely enter the drilling rig cavity for detection by the measuring part. If no water body is detected at the current drilling depth, it is only necessary to continue drilling for detection. The construction steps of water level measurement are simple and efficient, and the water level data is accurate and reliable.

[0029] 2. The integrated drilling and water level measurement device provided by the present invention has a partition arranged in the drilling rig, and a mounting portion is arranged on the partition for mounting the water level measuring component. The airbag is connected to the side of the partition facing the water permeable hole. The partition can guide the airbag to expand toward the side where the water permeable hole is located, which is beneficial for the airbag to discharge impurities and excess gas in the cavity out of the air hole by inflation and deflation.

[0030] 3. In the integrated drilling and water level measurement device provided by the present invention, the partition is sealed and connected to the inner wall of the drilling rig. After the partition is connected with the water level measuring component and the air bag, a sealing surface is formed. The partition can prevent the fluid from flowing from one side of the partition toward the water permeable hole to the other side of the partition to protect the water level measuring component. At the same time, it is easier to guide the air bag to expand toward the side where the water permeable hole is located, which is more conducive to the air bag to discharge impurities and excess gas in the cavity out of the air hole by inflation and deflation.

[0031] 4. In the integrated drilling and water level measurement device provided by the present invention, the water-permeable hole is arranged on the outer surface of the drill bit. Compared with the water-permeable hole arranged on the outer surface of the drill rod, the water-permeable hole is arranged at a lower position, which reduces the required drilling depth of the drilling rig. The water-permeable hole is arranged on the side of the partition away from the drill rod, and the side of the partition facing the water-permeable hole is connected to an air bag. The air bag can discharge mud and gravel out of the water-permeable hole by repeated inflation and deflation steps, so that water can be smoothly filled into the cavity. In addition, the air bag can discharge excess gas in the cavity by repeated inflation and deflation steps, which is beneficial to the filling of water into the cavity and also improves the measurement accuracy of the water pressure measuring piece.

[0032] 5. In the integrated drilling and water level measurement device provided by the present invention, the water level measuring component is connected to the signal terminal by wire, and the signal transmission is more stable, ensuring that when the drilling rig is at a large drilling depth, the signal terminal can still obtain the water level information measured by the measuring part. In addition, the signal terminal can also be equipped with a power supply to power the water level measuring component, thereby reducing the overall volume of the water level measuring component and facilitating the arrangement of the water level measuring component in the drilling rig.

[0033] 6. The integrated drilling and water level measurement device provided by the present invention comprises a drill rod connected by unit tubes. During the drilling process, the drill rod can be extended in length by continuously connecting new unit tubes until the water level measuring device detects the water level information. The length of the drill rod can be flexibly controlled by adjusting the number of connected unit tubes, and the drilling rig has a wider applicability.

[0034] 7. In the water level measuring method of the integrated drilling and water level measuring device provided by the present invention, the water level measuring component is arranged inside the drilling rig, and an air bag is also arranged inside the drilling rig. The air bag is suitable for connecting with external air intake and exhaust equipment through an air intake channel. When the water level measuring component obtains water level data, the air bag is inflated and deflated for many times through the air intake and exhaust equipment. The air bag discharges mud and gravel from the drilling rig by repeating the inflation and deflation steps, so that water can be smoothly poured into the drilling rig. In addition, the air bag can discharge excess gas from the drilling rig by repeating the inflation and deflation steps, which is beneficial for water to be poured into the drilling rig and improves the measurement accuracy of the water pressure measuring component. The construction steps of water level measurement are simple and efficient, and the water level height can be measured without pulling out the drilling rig after drilling.

[0061] In this embodiment, a cavity 101 is provided inside the drilling rig, and the cavity 101 is connected to a water-permeable hole 111 provided on the outer surface of the drilling rig. The measuring part 31 of the water level measuring part 30 is provided in the cavity 101. An air bag 40 is also provided in the cavity 101. The drilling rig is provided with an air intake channel 22 connecting the air bag 40 with the outside world. The air bag 40 is suitable for being connected with the external air intake and exhaust equipment through the air intake channel 22. The signal terminal is communicatively connected with the water level measuring part 30, and can obtain the water level information measured by the measuring part 31. The measuring part 31 of the water level measuring member 30 is arranged in the cavity 101 inside the drilling rig. When the drilling rig drills into the formation, if there is water in the formation, the water can be poured into the cavity 101 through the water permeable holes 111 opened on the outer surface of the drilling rig. After the measuring part 31 senses the water, it transmits the signal to the signal terminal. Combined with the installation position of the measuring part 31 on the drilling rig and the drilling depth of the drilling rig, the water level information of the drilling rig is obtained. The airbag 40 of the inflatable component is arranged in the cavity 101. The airbag 40 It can be connected with the external air intake and exhaust equipment, and the volume can be changed under the action of the air intake and exhaust equipment. When the water-permeable hole 111 is blocked by mud and gravel in a harsh and complex formation environment, the airbag 40 discharges the mud and gravel from the water-permeable hole 111 by repeating the inflation and deflation steps, so that the water body can be smoothly poured into the cavity 101. In addition, the airbag 40 can discharge the excess gas in the cavity 101 by repeating the inflation and deflation steps, which is conducive to the water body pouring into the cavity 101 and also improves the measurement accuracy of the water pressure measuring part. Compared with the traditional technology of drilling and water level measurement in steps, the integrated drilling and water level measurement device provided in this embodiment can measure the water level without pulling out the drilling rig after drilling. The inflation component can discharge the air in the drilling rig cavity 101, so that the water body can completely enter the drilling rig cavity 101 for detection by the measuring unit 31. If the water body is not detected at the current drilling depth, it is only necessary to continue drilling and detection. The construction steps of water level measurement are simple and efficient, and the water level data is accurate and reliable.

[0062] In this embodiment, the installation positions of the water level measuring member 30 and the airbag 40 in the cavity 101 are not specifically limited. When the airbag 40 is deflated, it does not affect the measuring part 31 of the water level measuring member 30 to detect the water body in the cavity 101. As an implementation method, the water level measuring member 30 and the airbag 40 are both fixed on the inner wall of the cavity 101; as another implementation method, a partition 14 is provided in the drilling rig, and a mounting part 141 is provided on the partition 14.

In this embodiment, the partition 14 is sealed and connected to the inner wall of the drilling rig, and the partition 14 is suitable for forming a sealing surface after being connected with the water level measuring member 30 and the air bag 40, so as to prevent the fluid from flowing from one side of the partition 14 toward the water permeable hole 111 to the other side of the partition 14, so as to protect the water level measuring member 30, and at the same time, it is easier to guide the air bag 40 to expand toward the side where the water permeable hole 111 is located, which is more conducive to the air bag 40 to discharge impurities and excess gas in the cavity 101 out of the air permeable hole by inflation and deflation. In an alternative embodiment, after the partition 14 is connected to the water level measuring member 30 and the airbag 40, no sealing surface is formed, and the other structures of the water level measuring member 30 except the measuring part 31 are waterproofed, specifically, the outer surface may be wrapped with a rubber sleeve.

[0095] S3, turn on the power 56, read the water head reading of the water level measuring member 30, if the water head reading is 0, turn off the power 56, continue drilling, if the drill rod 20 is not long enough, loosen the connection between the handheld end 50 and the drill rod 20, connect another unit tube 21 to the drill rod 20, connect the handheld end 50 to the newly connected unit tube 21, and then continue to slowly screw in the drill bit 10 and the drill rod 20 to the depth of the desired water level; if the water head reading at the position to be measured is not 0, the air intake pipe is connected to the air intake and exhaust equipment, and the air intake and exhaust equipment is operated to inflate and deflate the airbag 40 multiple times. After each inflation and deflation, gently shake the drill rig, count after the water head reading stabilizes, and the stable water head reading h is the water head value of the point, turn off the power 56, and for the location where the water level changes, a drilling and water level measurement integrated device can be placed for continuous observation;

[0096] S4. Calculate the water level H at the measurement location. Specifically, the following formula can be used:

[0097] H = h1 + n * h0 - h2 - h;

[0098] In the formula, h1 is the distance from the bottom of the measuring part 31 of the water level measuring component 30 to the end of the connecting seat 12 facing the drill pipe 20, which is a fixed value; h0 is the length of the unit tube 21; n is the number of unit tubes 21 used; h is the length of the last unit tube 21 exposed to the ground; h is the water head value measured by the water level measuring component 30. If the water level measuring component 30 is a water pressure gauge and the reading is P, then h can be obtained by P=ρgh, where ρ is the density of water and g is the value of gravity acceleration.
