Description

Technical Field

[0001] This invention relates to the field of drill pipe equipment technology, and specifically to a drill pipe equipment for petroleum geological exploration. Background Technology

[0002] As is well known, before oil extraction, it is necessary to conduct oil geological exploration. On the one hand, it is necessary to determine the oil reserves, and on the other hand, it is necessary to explore the geology of the area where the oil is located in order to provide the necessary technical parameters for subsequent oil extraction. Drill pipe devices are usually used in oil geological exploration to sample underground geology.

[0003] A search revealed that Chinese patent CN110685598A, published on January 14, 2020, discloses a drill pipe device for oil geological exploration. Its general description includes a frame and a drilling mechanism. A connecting frame is welded to the top of one end of the frame, and the connecting frame is movably connected to the drilling mechanism via a screw. A support frame fixed to the frame is provided on one side of the connecting frame. A first cylinder located inside the frame is located below the support frame. A first pneumatic rod is connected to the top of the first cylinder at an angle, and one end of the first pneumatic rod is connected to the side wall of the drilling mechanism. A first power supply located on the top of the frame is fixedly installed on one side of the support frame. Chinese patent CN112796679A, published on May 14, 2021, also discloses... A petroleum geological exploration drill pipe device includes a vehicle body, a hydraulic tank at the front end of the vehicle body, an annular frame at the lower end of the hydraulic tank, a first drill pipe at the lower end of the annular frame, a spiral sleeve at the lower end of the first drill pipe, a second drill pipe at the lower end of the spiral sleeve, and an annular sleeve at the lower end of the second drill pipe. Guide blocks are evenly installed on the surface of the annular sleeve. The spiral sleeve is bidirectionally spirally connected, with one end spirally connected to a threaded pipe and the other end spirally connected to the drill pipe. During operation, the guide blocks divert soil and other materials below, reducing blockage and improving work efficiency. The fixing plate inside the annular sleeve connects and fixes the drill bit and the annular sleeve, while reducing the stress area and improving service life. When the drill bit collects liquid samples, impurities in the liquid can be filtered out through a filter screen, improving work efficiency.

[0004] While the two existing technical solutions mentioned above can achieve sampling in petroleum geological exploration, the terrain and geological structure of the exploration sites are not entirely the same. Therefore, there are inevitably some testing sites with uneven surface environments. For relatively harsh surface environments, the two petroleum geological exploration drill pipe devices mentioned above inevitably face difficulties in access. At the same time, the drill pipe construction has a high degree of difficulty. The existing solutions all adopt the method of using leveling mechanism vehicles and drilling machinery to work separately and in coordination. Although this approach can facilitate high-quality drilling operations, it requires the cooperation of multiple trades, resulting in low work efficiency. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a petroleum geological exploration drill rod device. During the process of entering the exploration site, it can level the difficult-to-access exploration site, facilitating the entry of the carrier vehicle. At the same time, during drilling, it can form support for the drilling mechanism according to the terrain characteristics, resulting in better positional stability of the drilling mechanism during construction and reducing the difficulty of construction.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, the present invention provides a drill pipe device for petroleum geological exploration, which has the following beneficial effects:

[0020] 1.

[0030] Example

[0031] Please see Figures 1-6A drilling rod device for petroleum geological exploration includes a drilling mechanism 1 and a carrier vehicle 2. A carrying bucket 3 is mounted on the carrier vehicle 2, and an installation box 4 is rotatably connected inside the carrying bucket 3. A main hydraulic cylinder controls the rotation of the installation box 4 relative to the carrying bucket 3, facilitating the rotation and erection of the installation box 4 during operation and its subsequent storage inside the carrying bucket 3. This facilitates drilling rod operation of the drilling mechanism 1 and transportation after operation. The drilling mechanism 1 is installed inside the installation box 4. A main hydraulic cylinder is installed between the carrier vehicle 2 and the installation box 4. The front, top, and rear ends of the installation box 4 have recesses, each with a connecting plate 5 fixedly connected. Support plates 6 are rotatably connected to each of the three connecting plates 5. The rotatable connection between the connecting plates 5 and the support plates 6 facilitates the unfolding of the support plates 6 during support and their folding after use. Auxiliary hydraulic cylinders are installed between each of the three support plates 6 and the installation box 4. Each of the three support plates 6 has... The installation ports are equipped with ground anchor devices, each consisting of a rotating block 8 rotatably connected to one of the installation ports. The rotating block 8 has a spiral hole through which a spiral rod 9 is connected. One end of the spiral rod 9 has a spiral tip 26 for drilling. Two round rods 10 are fixedly connected to the rotating block 8, and sliders 11 are slidably connected to the two round rods 10. A circular opening is provided on the slider 11, through which the spiral rod 9 is rotatably connected. A power motor for driving the spiral rod 9 is installed on the slider 11. The power motor is electrically connected to the carrier vehicle 2, enabling the support arm plate 6 to be positioned relative to the exploration site. This improves the stability of the relative position of the drilling mechanism 1 to the exploration site during construction, allowing the drilling mechanism 1 to be supported according to the terrain features. The drilling mechanism 1 exhibits good positional stability during construction, reducing the difficulty of construction.

[0032] It should be further explained that each of the three support arm plates 6 is equipped with a locking assembly for stabilizing the ground anchor device. The locking assembly includes a pin cylinder 12, with an embedded groove on the support arm plate 6. The pin cylinder 12 is fixedly connected to the embedded groove, and a pin post 13 is slidably fitted inside the pin cylinder 12. The pin cylinder 12 has a movable opening, and a locking plate 14 is installed in the movable opening. The locking plate 14 is fixedly connected to the pin post 13. A magnetic lock matching the locking plate 14 is installed in the embedded groove. The slider 11 has a pin groove matching the pin post 13 to facilitate the stability of the slider 11 in the installation opening after use. The front and rear ends of the carrier vehicle 2 are rotatably connected to the main arms 7. Hydraulic lifting cylinders are installed between the two main arms 7 and the carrier vehicle 2. A flattening structure is installed on the two main arms 7. The entire structure includes two straight slide rods 15, each with a sliding opening on one of the two main arms 7. The two straight slide rods 15 are slidably connected within these openings. Rotating slide rods 16 are rotatably connected to each of the two straight slide rods 15, and the two rotating slide rods 16 are connected by a connecting assembly. Sliding sleeves 17 are slidably connected to each of the two rotating slide rods 16. Rectangular bars 24 are fixedly connected to both the rotating slide rods 16 and the straight slide rods 15. Rectangular openings matching the rectangular bars 24 are provided on both the sliding sleeves 17 and the main arms 7, facilitating the directional movement between the rotating slide rods 16 and the sliding sleeves 17, and between the straight slide rods 15 and the main arms 7. Limiting rings 25 are fixedly connected to the straight slide rods 15 to restrict the movement between the straight slide rods 15 and the main arms 7. At extreme positions, the system is relatively reliable. Two sliding sleeves 17 are each fixedly connected to a flat arc plate 18, and an adjusting spring 19 is fixedly connected between the two flat arc plates 18. This allows the oil geological exploration drill pipe device to flatten difficult-to-access exploration sites during entry, facilitating the entry of the carrier vehicle 2. The connecting assembly includes a middle plate frame 20, which is connected to a rotating slide rod 16 via a rotating shaft. A middle connecting plate 21 is fixedly connected to the front end of the middle plate frame 20, facilitating the connection of the gap between the two flat arc plates 18. An adjustment structure for adjusting the flattening structure is provided at the left end of the flattening structure. The adjustment structure includes a fixed rod 22, and a hydraulic push rod is installed at the right end of the fixed rod 22. The hydraulic push rod is connected to the middle plate frame 20, enabling… The leveling structure can be adjusted to a leveling mode, facilitating the leveling structure to push open obstacles at the exploration site and to cooperate with the hydraulic lifting cylinder to scoop up and clear obstacles. The adjustment structure is installed between the two main arms 7. The carrier vehicle 2 is equipped with a hydraulic system that matches the main hydraulic cylinder, auxiliary hydraulic cylinder, hydraulic lifting cylinder and adjustment structure. The hydraulic system includes a hydraulic oil tank 23 and a hydraulic pump. Both the hydraulic oil tank 23 and the hydraulic pump are installed on the carrier vehicle 2. The hydraulic pump is connected to the hydraulic oil tank 23. The main hydraulic cylinder, auxiliary hydraulic cylinder, hydraulic lifting cylinder and hydraulic push rod are all connected to the hydraulic pump to provide hydraulic power for the hydraulic components in the petroleum geological exploration drill pipe device. A protective frame for protecting the hydraulic pump is fixedly connected between the carrier vehicle 2 and the bucket 3 to protect the hydraulic pump.

[0033] In summary, before use, this petroleum geological exploration drill pipe device is first moved to the desired exploration location. The carrier vehicle 2 is designed with a driver's cab, which is equipped with a driving system. During the movement, the operator enters the driver's cab and uses the driving system to control the carrier vehicle 2 to move the bucket 3, transporting the drilling mechanism 1 to the desired exploration location. During the movement, when there are obstacles in the area traversed by the carrier vehicle 2, the relative positions of the two flat arc plates 18 are adjusted according to the specific circumstances of the obstacles. When the obstacle is small, the hydraulic push rod pushes the middle plate frame 20 forward. During the movement of the middle plate frame 20, the two flat arc plates 18 are moved forward. The sliding rod 16 is rotated so that the two adjacent ends of the sliding rod 16 tilt to the right, causing the two adjacent ends of the flat arc plates 18 to also tilt to the right. After adjustment, the main arm 7 is rotated by the hydraulic lifting cylinder, causing the right end of the main arm 7 to fall and the two flat arc plates 18 to fall as well. This allows the carrier vehicle 2 to push away obstacles that hinder its movement during its movement. When the obstacle is large, the flat arc plate 18 is controlled by the hydraulic lifting cylinder, causing it to fall and rise repeatedly in coordination with the left and right movement of the carrier vehicle 2, thus decomposing and clearing larger obstacles and facilitating the smooth entry of the carrier vehicle 2 into the exploration area.

[0034] Furthermore, after the carrier vehicle 2 enters the exploration area, the best working location within the exploration area is selected, and the carrier vehicle 2 is parked at that location. The main hydraulic cylinder controls the installation box 4 to rotate relative to the bucket 3, so that the installation box 4 forms a suitable angle with the working surface of the exploration location. Then, the auxiliary hydraulic cylinder controls the support arm plate 6 to rotate and open relative to the connecting plate 5 until the support arm plate 6 contacts the working surface. Before the support arm plate 6 contacts the working surface, the magnetic lock is opened, and the locking plate 14 moves the pin 13 relative to the pin cylinder 12 until the pin 13 completely exits the pin groove, so that the positioning function of the slider 11 in the installation port is invalidated. The rotating block 8 is adjusted to rotate in the installation port, and the helical rod 9 is adjusted to match the working surface. After the support arm plate 6 is adjusted, the power motor is turned on, so that the power motor drives the helical rod 9 to feed relative to the rotating block 8 until the helical rod 9 enters the working surface and is sufficient to achieve the positioning of the installation box 4. Then, the drilling mechanism 1 is started to carry out the operation.

[0035] Furthermore, since there are many mature products on the market for main hydraulic cylinders, auxiliary hydraulic cylinders, hydraulic lifting cylinders, hydraulic push rods, hydraulic pumps, and power motors, the products involved in this implementation are all existing products selected from the market based on actual usage needs. The structure and function of these products have not been changed, and the corresponding manufacturers will provide instruction manuals and related technical support for the installation and use of the products. Therefore, we will not go into too much detail about these aspects here.
