Description

Technical Field

[0001] This utility model relates to the field of oil extraction technology, and more specifically, to an oil drilling device. Background Technology

[0002] Petroleum is a fluid mineral buried deep underground. Initially, people called naturally occurring oily liquid minerals petroleum, combustible gases natural gas, and solid combustible fuel minerals bitumen. Drilling plays a crucial role in oil and gas field development, often accounting for more than 50% of the total investment in constructing an oil and gas field. Developing an oil and gas field often requires drilling hundreds, even thousands, or more wells. Different wells have different technical requirements for different purposes such as extraction, observation, and control. The drilled wells must minimize contamination of the oil and gas reservoir, have high-quality cementing, and be able to withstand the effects of various downhole operations over decades of extraction. Improving drilling technology and management, and increasing drilling speed, are key to reducing drilling costs.

[0003] A search revealed that Chinese utility model patent application number CN202021419179.1 discloses a drilling equipment for oil exploration, including a housing with through holes at the top and bottom. Vertical plates are welded to both sides of the top of the housing, and slides are provided on opposite sides of the two vertical plates. Limiting blocks are slidably connected to the two slides, and a motor housing is fixedly installed between the two limiting blocks. A motor is fixedly installed inside the motor housing.

[0004] When in use, the drill rod is rotated by a motor to drill a hole. The soil produced during drilling will accumulate around the top of the hole and under the support base. When there is a lot of soil accumulated under the support base, it is not easy to disperse the soil. Because a large amount of soil is accumulated around the top of the hole, it is not easy for the soil inside the hole to be discharged smoothly. Utility Model Content

[0030] Please see Figures 1-5 A drilling rig for oil exploration includes a support base 1. Rollers 26 are fixedly connected to the four corners of the bottom of the support base 1, allowing it to roll on the ground for easy movement. A base 2 is positioned above the support base 1, with a push handle 27 fixedly connected to its top for easy pushing. Multiple first hydraulic cylinders 3 are fixedly connected to the base 2, with the bottom ends of the telescopic rods of each cylinder fixedly connected to the top of the support base 1. A drilling mechanism is fixedly connected to the top of the base 2. The drilling mechanism is mounted on the base 2. A rotating pipe 4 is rotatably connected to the corresponding position. Multiple vertical plates 5 are fixedly connected to the bottom end of the rotating pipe 4. Bulldozer plates 6 are fixedly connected to the side ends of the multiple vertical plates 5. A first gear 7 is fixedly connected to the outside of the rotating pipe 4. A fixing frame 8 is fixedly connected to the top of the base 2. A first motor 9 is fixedly installed on the fixing frame 8. A second gear 10 is fixedly connected to the output end of the first motor 9. The second gear 10 meshes with the first gear 7 to facilitate pushing away the soil around the top of the borehole, preventing soil from accumulating at the borehole opening, and facilitating the discharge of soil from inside the borehole.

[0031] Specifically, during the drilling process, the first motor 9 drives the second gear 10 to rotate, and the second gear 10 drives the first gear 7, the rotating pipe 4, multiple vertical plates 5 and multiple bulldozer plates 6 to rotate. The multiple bulldozer plates 6 push away the soil around the borehole on the ground. As the multiple bulldozer plates 6 rotate, the soil is thrown to the surrounding area, thereby preventing soil from accumulating at the borehole opening and below the support base 1, and facilitating the smooth discharge of soil from inside the borehole.

[0032] Please see Figure 1 and Figure 5 The drilling mechanism includes a U-shaped frame 11, the bottom end of which is fixedly connected to the top end of the base 2. A fixed frame 12 is slidably arranged inside the U-shaped frame 11. A second motor 13 is fixedly connected inside the fixed frame 12. A drill rod 14 is fixedly connected to the output end of the second motor 13. The drill rod 14 passes through the inside of the rotating tube 4 and extends to the bottom of the support base 1. A second hydraulic cylinder 15 is fixedly connected to the top end of the U-shaped frame 11. The telescopic rod of the second hydraulic cylinder 15 is fixedly connected to the top end of the fixed frame 12. Two sliding grooves 16 are provided on the U-shaped frame 11. Two sliding blocks 17 are fixedly connected to the fixed frame 12. The two sliding blocks 17 slide and engage with the two sliding grooves 16 respectively to ensure that the fixed frame 12 slides stably inside the U-shaped frame 11.

[0033] Specifically, the second motor 13 drives the drill rod 14 to rotate, and the second hydraulic cylinder 15 pushes the fixed frame 12 and the drill rod 14 downward, so that the drill pipe is gradually inserted into the ground and drills a hole.

[0034] Please see Figure 2 The bottom end of the base 2 is fixedly connected to a baffle pipe 18, which is sleeved on the outside of multiple bulldozer blades 6. The side end of the baffle pipe 18 is provided with a soil discharge port 19 to prevent the thrown soil from falling on the surrounding workers and to avoid injury to the workers.

[0035] Specifically, a baffle pipe 18 is fixedly connected to the bottom of the base 2. The baffle pipe 18 is sleeved on the outside of multiple bulldozer blades 6. The baffle pipe 18 prevents soil from being thrown around and prevents soil clods from being thrown onto the surrounding workers, thus avoiding injury to the workers.

[0036] Please see Figure 1 and Figure 2A conveying pipe 20 connected to the soil discharge port 19 is fixedly connected to the base 2. A third motor 21 is fixedly connected to the top of the conveying pipe 20. A conveying shaft 22 is fixedly connected to the output end of the third motor 21. A spiral blade 23 is fixedly connected to the outside of the conveying shaft 22. A soil discharge pipe 24 is connected to the upper side of the side end of the conveying pipe 20. The soil discharge pipe 24 extends to the outside of the base 2, which facilitates the conveying of soil below the support 1 to one side of the support 1, and avoids the accumulation of soil below the support 1. A through groove 25 is provided on the support 1. The bottom ends of the baffle pipe 18 and the conveying pipe 20 are both located inside the through groove 25.

[0037] Specifically, the soil inside the baffle pipe 18 is discharged through the soil discharge port 19 and discharged into the conveying pipe 20. The third motor 21 drives the conveying shaft 22 and the spiral blade 23 to rotate. The rotation of the spiral blade 23 transports the soil from the bottom side of the conveying pipe 20 to the top side of the conveying pipe 20. The soil is then discharged through the soil discharge pipe 24 to the outside of the support base 1, preventing soil from accumulating below the support base 1.

[0038] In summary, when using the overall equipment:

[0039] First, move the equipment to the location where drilling is needed. Then, lock the rollers 26. Adjust the height of the base 2, the baffle pipe 18, and the conveying pipe 20 using multiple first hydraulic cylinders 3, so that the bottom ends of the baffle pipe 18 and the conveying pipe 20 contact the ground. Then, drive the drill rod 14 to rotate via the second motor 13. Push the fixed frame 12 and the drill rod 14 downward via the second hydraulic cylinder 15, so that the drill rod 14 gradually inserts into the ground and drills a hole. The soil produced during drilling will be discharged to the area around the top of the hole. At the same time, drive the second hydraulic cylinder 15 via the first motor 9. When gear 10 rotates, the second gear 10 drives the first gear 7, the rotating pipe 4, multiple vertical plates 5 and multiple bulldozer plates 6 to rotate. The multiple bulldozer plates 6 push away the soil around the drilled hole on the ground. As the bulldozer plates 6 push the soil to rotate, the soil is pushed through the discharge port 19 into the inside of the conveying pipe 20. The third motor 21 drives the conveying shaft 22 and the spiral blade 23 to rotate. The spiral blade 23 rotates to transport the soil from the bottom side of the inside of the conveying pipe 20 to the top side of the conveying pipe 20. The soil is discharged through the discharge pipe 24 to the outside of the support base 1.
