By analyzing the organic matter content and mineral composition in soil samples, important information about reservoir characteristics, such as oil type and oil content, can be provided. In addition to deep sampling, shallow soil sampling is also important in oil exploration. Compared with deep soil, shallow soil sampling is a fast, economical and safe exploration method that can reveal the geological structure, surface environment and soil type of the study area. This is of great significance for the regional selection of oil exploration and the planning of subsequent work (such as evaluating the potential impact of oil extraction activities on the environment, such as post-exploitation soil pollution risk assessment, etc.).
[0003] Currently, existing geological sampling equipment, such as soil sampling drills, are mostly used for shallow soil sampling. Such sampling drills are small in size and light in weight, often cannot penetrate the soil well, and are difficult to use in some areas with hard soil. Summary of the invention

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0029] Please refer to Figure 1 to Figure 3 , an embodiment of the present application provides a soil sampling device for oil exploration, comprising a support plate 1, an auger mechanism 2, a driving mechanism 3 and a sampling mechanism 4;
[0030] The support plate 1 is set in a plate shape, and is used to provide support and working space for the entire device; the bottom surfaces of the four corners of the support plate 1 are fixedly provided with support rods 11 in the vertical direction;
[0031] An auger mechanism 2 is installed vertically below one end of the support plate 1 along the length direction, and a driving mechanism 3 is installed on the top surface of the other end;
[0032] A sampling mechanism 4 is installed on the auger mechanism 2 .
[0033] In this embodiment, the drum 21 is driven by the gasoline engine 31 to rotate with high power and high torque, and the spiral blades 22 are used to drill deep into the soil. The multiple crushing drills 23 inside the drum 21 can crush the soil in the drum 21, so that the soil in the drum 21 is broken up and softened, making it easy to insert the sampling drill 41. This device can be used in soil environments with hard soil, and the overall device structure is simple and practical, and is stable and safe when used.
[0034] In a preferred embodiment, the auger mechanism 2 includes a rotating drum 21, spiral blades 22 and a crushing drill 23;
[0035] The rotating drum 21 is set in a cylindrical shape; the top end of the rotating drum 21 along the axial direction penetrates the support plate 1 and is rotatably connected to the support plate 1; the outer wall of the rotating drum 21 is spirally fixed with a spiral blade 22; the inner wall of the rotating drum 21 is fixedly provided with a crushing drill 23 along the diameter direction; the drill head of the crushing drill 23 is close to the axis of the rotating drum 21 along the diameter direction of the rotating drum 21; the length of the crushing drill 23 is smaller than the radius of the rotating drum 21;
[0036] A plurality of crushing rods 23 are arranged in a circumferential direction.
[0037] Please refer to Figure 1 to Figure 3 In this embodiment, the drum 21 is connected to the driving mechanism 3 in a transmission manner. The drum 21 cooperates with the spiral blades 22 to break the soil and drill deep, so that the entire device drills deep to a specified position in the vertical direction, making it easier for the sampling mechanism 4 to reach a specified soil depth.
[0038] The crushing chisel 23 is arranged in a cone shape, and the plurality of crushing chisels 23 arranged in an arranged manner are used together to break and crush the soil, so that the soil in the drum 21 is broken and softened during the deep drilling process, which is convenient for the sampling mechanism to take samples.
[0039] In a preferred embodiment, the driving mechanism 3 includes a gasoline engine 31 and a belt 32; the gasoline engine 31 is installed on the top surface of one end of the support plate 1 away from the rotating drum 21 along the length direction; the gasoline engine 31 is connected to the top end of the rotating drum 21 through the belt 32.
[0040] Please refer to Figure 1 to Figure 3 In this embodiment, the gasoline engine 31 is configured as a small gasoline engine, which uses gasoline as fuel and converts internal energy into kinetic energy to drive the drum 21 to rotate. This is a conventional technology in the field and is not within the scope of protection of this patent.
[0041] In a preferred embodiment, the sampling mechanism 4 includes a sampling pin 41 and a handle 42; a support frame 13 is fixedly provided on the top surface of the support plate 1 corresponding to the rotating cylinder 21; a hole is penetrated through the support frame 13 along the axial direction of the rotating cylinder 21, and the sampling pin 41 is movably provided in the hole; the lower and middle parts of the sampling pin 41 are hollow, and the bottom end is conical; a channel 43 is penetrated through the corresponding hollow part along the diameter direction on the sampling pin 41; a handle 42 is fixedly provided on the top of the sampling pin 41.
[0042] Please refer to Figure 1 to Figure 3 In this embodiment, the sum of the radius of the sampling rod 41 and the length of the crushing rod 23 is smaller than the inner radius of the drum 21 , which facilitates the sampling rod 41 to move up and down along the axis of the drum 21 .
[0043] The support frame 13 is used to stabilize the sampling rod 41 so that it is more stable and less likely to deviate when vertically inserted into the interior of the rotating drum 21 for sampling.
[0044] The channel 43 on the sampling rod 41 facilitates the removal of the sample along the axial direction of the sampling rod 41 after sampling. When removing the sample, a cylinder can be inserted into any position of the channel 43 on the sampling rod 41, and then the cylinder can be pressed down to press out the sample soil at the required position and the position below.
[0045] In a preferred embodiment, second handles 12 are fixedly provided on the top surfaces of both ends of the support plate 1 along the length direction.
[0046] Please refer to Figure 1 to Figure 3 In this embodiment, the second handle 12 is used to hold the entire device in a stable manner.
[0047] How this application works:
[0048] Place the drum 21 vertically on the top surface of the soil area to be sampled, hold the two second handles 12 with both hands, then start the gasoline engine 31, press down the drum 21, and the drum 21 rotates driven by the gasoline engine 31, and uses the spiral blade 22 to drill deep into the soil. At the same time, the crushing drill 23 inside the drum 21 crushes the soil in the drum 21. When the drum 21 drills to a certain depth, use the support drill 11 to support the support plate 1, and then insert the sampling drill 41 from the hole on the support frame 13 at the top of the drum 21 along the axial direction of the drum 21. Since the soil in the drum 21 is broken and soft, the sampling drill 41 is easy to insert. This device can be used in a soil environment with hard soil. Then, pull out the sampling drill 41 for sampling. The overall device has a simple and practical structure and is stable and safe when used.
