[0035] To overcome the problems existing in the related art, the exemplary embodiment of the present disclosure provides an artificial core specimen, as Figure 1 shown, the artificial core specimen as a whole can be cylindrical and can include: a first semi-cylinder 100 and a second semi-cylinder 200. The first semi-cylinder 100 and the second semi-cylinder 200 can each be columnar as a whole, and the cross-section can be semi-circular, and the first semi-cylinder and the second semi-cylinder are combined to form a cylinder.

[0036] The first semi-cylinder 100 may have core textures formed on its surface, wherein, asFigure 2 As shown, the arc-shaped cylindrical surface 110 of the first semi-cylindrical body 100 can be used to display the external characteristics of the core. Such as Figure 3 As shown, the flat cylindrical surface 120 of the first semi-cylindrical body 100 can be used to display the internal characteristics of the core. The surface of the second semi-cylindrical body 200 can be formed with core textures. Among them, the arc-shaped cylindrical surface 210 of the second semi-cylindrical body 200 can be used to display the external characteristics of the core, and the flat cylindrical surface 220 of the second semi-cylindrical body 200 can be used to display the internal characteristics of the core. Each surface of the first semi-cylindrical body 100 and the second semi-cylindrical body 200 can be formed with core textures, and the core textures can display the characteristics of the core. Among them, the core textures can be generated based on the high-definition images of real cores, or can be generated according to the characteristics of certain types of cores. The core textures can be coated on the outer surfaces of the first semi-cylindrical body 100 and the second semi-cylindrical body 200 by spraying, or can be covered on the outer surfaces of the first semi-cylindrical body 100 and the second semi-cylindrical body 200 by film covering, or can be directly formed on the outer surfaces of the first semi-cylindrical body 100 and the second semi-cylindrical body 200 by 3D printing technology along with the preparation of the first semi-cylindrical body 100 and the second semi-cylindrical body 200. Such as Figure 1As shown, the arc-shaped cylindrical surface 110 of the first semi-cylindrical body 100 is a semi-cylindrical arc-shaped surface, and the formed texture is used to display the external characteristics of the core; correspondingly, the texture formed by the arc-shaped cylindrical surface 210 of the second semi-cylindrical body 200 can be used to display the external characteristics of the core, corresponding to the texture formed by the arc-shaped cylindrical surface 110 of the first semi-cylindrical body 100. In the state of being joined with the first semi-cylindrical body 100 to form a cylinder, the textures of the arc-shaped cylindrical surface 210 of the second semi-cylindrical body 200 and the arc-shaped cylindrical surface 110 of the first semi-cylindrical body 100 are continuous, jointly displaying the complete external characteristics of the core. The flat cylindrical surface 120 of the first semi-cylindrical body 100 is semi-cylindrical, a plane opposite to the arc-shaped cylindrical surface, and the formed texture is used to display the internal characteristics of the core; correspondingly, the texture formed by the flat cylindrical surface 220 of the second semi-cylindrical body 200 is used to display the internal characteristics of the core, corresponding to the texture formed by the flat cylindrical surface 120 of the first semi-cylindrical body 100, which can be mirror-symmetrical and can truly restore the internal texture information of the natural core when the first semi-cylindrical body 100 and the second semi-cylindrical body 200 are separated. By forming two semi-cylindrical bodies, the artificial core specimen of the present disclosure can conveniently display the internal characteristics of the core and provide more core information compared with an integral core specimen. The materials of the first semi-cylindrical body 100 and the second semi-cylindrical body 200 are close to the stone texture of the real core and can be prepared by a certain artificial core preparation method. For example, the texture characteristics of the real core can be obtained through computer tomography technology, and then the artificial core specimen can be prepared by 3D printing technology. The first semi-cylindrical body 100 and the second semi-cylindrical body 200 can be solidly printed with a hard material, such as a photosensitive resin material, etc. This material has a large density, rich colors and is strong and durable, and can truly restore the core information. It can also be hollow printed. When printing, a certain wall thickness can be set for the first semi-cylindrical body 100 and the second semi-cylindrical body 200, such as 1-3 cm. The appearance is still printed with a resin material, and the weight of the first semi-cylindrical body 100 and the second semi-cylindrical body 200 is calculated according to the density of the physical core for the hollow part inside. A material with a larger weight, such as gypsum, cement, hot melt adhesive, etc., is used for perfusion to reach or approach the weight of the physical core, and the information of the natural core can be truly restored.

[0037] The second semi-cylinder 200 can be detachably connected to the first semi-cylinder 100, and the flat cylindrical surface 220 of the second semi-cylinder 200 is disposed opposite to the flat cylindrical surface 120 of the first semi-cylinder 100. The second semi-cylinder 200 can be separated from the first semi-cylinder 100 to form two single parts for respectively displaying the external texture and the internal texture of the core; or they can be connected as a whole. In the connected state, the flat cylindrical surface 220 of the second semi-cylinder 200 is butted against the flat cylindrical surface 120 of the first semi-cylinder 100, so that the external arc-shaped cylindrical surface forms a complete external texture of the core. The connection method can be magnetic connection, screw connection, snap connection, etc. to achieve convenient disassembly and assembly. Moreover, the connection structure can be asymmetrically arranged, thereby ensuring that the connection directions of the first semi-cylinder 100 and the second semi-cylinder 200 are correct, and ensuring that the textures on the outer surfaces are aligned and continuous when the first semi-cylinder 100 and the second semi-cylinder 200 are in the connected state.

[0038] In the embodiments of the present disclosure, the artificial core specimen is split in half, and the first semi-cylinder 100 and the second semi-cylinder 200 are arranged to be detachably connected. In the separated state of the first semi-cylinder 100 and the second semi-cylinder 200, the internal texture characteristics of the core can be displayed while displaying the external texture of the core, highly restoring the core characteristics, facilitating observation, convenient for display, and improving the utilization rate of the artificial core specimen. When the first semi-cylinder 100 and the second semi-cylinder 200 are in the combined state, it is beneficial to display the external characteristics and convenient for storage.

[0039] The 3D printing steps for making artificial core specimens can be as follows: First step, data collation can be carried out. High-resolution scans or photographed images of natural cores and logging information can be collected and collated, and it can be checked whether the recorded information of artificial core specimens and natural cores matches and corresponds one by one. Second step, image preprocessing can be carried out. Software is used to process the external view and sectional view obtained by scanning or photographing. First, multiple external scan images or photographed images of the core are spliced to obtain a complete external view of the core, and the width of this view is the circumference of the semi-cylinder of the core. Similarly, if there are multiple sectional view images of the core, they can also be spliced to obtain a complete sectional view of the core, and the width of this view can be the diameter of the semi-cylinder of the core. For the broken and fractured parts in the figure, they can be restored according to the core description information and existing data pictures, and the parts that cannot be accurately restored can remain unchanged. Third step, labels can be added to the artificial core specimens. In the software, core labels can be added to the top and bottom of the column of the artificial core specimens. The sampling depth of the core can be marked on the external view of the core, that is, the elevation of the top and bottom boundaries of the core sampling, with the value being negative and the unit being meters, and the top texture and column texture with identification information can be obtained. Fourth step, a model of the artificial core specimen can be established and texture features can be added. In the software, using the "Create - Create Part - Cylinder" tool, a cylinder model of the artificial core specimen is made. At this time, the cylinder model has no texture and can be called a white model. Texture features can be added to the white model. Using "Tool - Mark Plane" to select the top of the column and choosing "Texture - New Texture", texture features can be added, and the top texture created in the third step is added to the white model. Textures are added to the bottom and column of the core respectively to obtain a core model with texture feature information. Fifth step, the section of the artificial core specimen can be made. In the software, using the "Cut or Punch" tool, the core model made in the fourth step is longitudinally cut open from the center to form two equal-sized semi-cylinders. Using the "Mark Plane" tool, one of the cut surfaces is selected, and the core sectional view made in the second step is added as the sectional texture. Similarly, the texture can be added to the other semi-cylinder section to complete the addition of all textures on the external and internal parts of the core model. Sixth step, magnet grooves can be set on the artificial core specimen. In the software, using the "Create - Create Part - Cuboid" tool, a group of cuboids are created to locate the groove positions. The cuboids and the core semi-cylinder are selected simultaneously, and using "Tool - Boolean Operation - Subtraction", a group of grooves are opened at the top and bottom of the core section for embedding strong magnets. Under the adsorption of the magnets, the two core semi-cylinders made in the fifth step are adsorbed together to maintain the original cylindrical shape of the artificial core specimen. Seventh step, QR code grooves can be set on the artificial core specimen. In the software, using the "Create - Create Part - Cuboid" tool, a cube is created, and the position of the cube should be selected at a place that does not affect the observation of the sectional texture and geological structure.Then, select the cube and the core semi-cylinder at the same time, and use "Tools - Boolean Operation - Subtraction" to obtain a QR code groove for pasting a QR code picture integrating the access URL of the digital core information platform. In the eighth step, you can export the file for 3D printing, export the completed core model in a certain format, and send it to a 3D color printer to complete the production and printing of the artificial core specimen.

[0040] In some embodiments, as Figure 4 shown, the flat cylindrical surface 120 of the first semi-cylinder 100 may be provided with a first groove 130 for inlaying a first magnetic attraction device 131. The shape of the first groove 130 may be rectangular or other polygons, circular, semi-circular, etc., and the depth of the groove may be 1-5 cm. There may be one first groove 130, which may be provided above or below the flat cylindrical surface 120 of the first semi-cylinder 100; there may also be two first grooves 130, which may be provided above and below the flat cylindrical surface 120 of the first semi-cylinder 100. The first magnetic attraction device 131 may be inlaid in the first groove 130, and the shape of the first magnetic attraction device 131 may correspond to that of the first groove 130, and may be rectangular or other polygons, circular, semi-circular, etc., and the thickness may be 1-5 cm. The material of the first magnetic attraction device 131 may be a hard magnetic material, for example, high carbon steel, etc. Such materials can maintain magnetism for a long time after magnetization and are not easy to lose magnetism.

[0041] The flat cylindrical surface 220 of the second semi-cylinder 200 may be provided with a second groove 230 corresponding to the first groove 110 for inlaying a second magnetic attraction device 231 that can be adsorbed to the first magnetic attraction device 131 so that the second semi-cylinder 200 is connected to the first semi-cylinder 100. The flat cylindrical surface 200 of the second semi-cylinder 200 is provided with a second groove 230 corresponding to the position of the first groove 130, and the shape and number of the second groove 230 may be the same as those of the first groove. In one embodiment, both the first groove 130 and the second groove 230 have two. The first magnetic attraction devices 131 inlaid in the two first grooves 130 have opposite magnetic polarities, and the two second magnetic attraction devices 231 inlaid in the two second grooves 230 have opposite magnetic polarities and respectively correspond to the first magnetic attraction devices 131, so that the first semi-cylinder 100 and the second semi-cylinder 200 can only be installed together in one direction, avoiding their inverted installation, so as to ensure that the texture features of the arc-shaped cylindrical surface 110 of the first semi-cylinder 100 and the texture features of the arc-shaped cylindrical surface 210 of the second semi-cylinder 200 can form a complete external texture feature of the core.

[0042] In the embodiments of the present disclosure, the detachable connection between the first semi-cylinder 100 and the second semi-cylinder 200 is realized by magnetic attraction, which can facilitate the disassembly and assembly of the first semi-cylinder 100 and the second semi-cylinder 200 and is convenient for observing the texture features inside the core specimen.

[0043] In some embodiments, such as Figure 4 shown, a groove for setting a two-dimensional code may be formed on one of the flat cylindrical surfaces 120 of the first semi-cylindrical body 100 and the flat cylindrical surface 220 of the second semi-cylindrical body 200, or grooves for setting two-dimensional codes may be formed on both the flat cylindrical surface 120 of the first semi-cylindrical body 100 and the flat cylindrical surface 220 of the second semi-cylindrical body 200. In one embodiment, the flat cylindrical surface 120 of the first semi-cylindrical body 100 may be provided with a third groove 140, which can be used to set the two-dimensional code 150 corresponding to the core information platform. The shape of the third groove 140 may be square, and the depth may be 1-5 cm, which can be used to set the two-dimensional code corresponding to the core information platform. By setting the two-dimensional code in the groove, it is possible to prevent the pattern of the two-dimensional code from being unclear or falling off due to frequent friction. The two-dimensional code 150 can be set in the form of pasting a picture of the two-dimensional code, or can be formed inside the third groove 140 by spraying or etching methods. The left-side directory of the page of the core digital platform can be the core code index; in the middle can be the digitized core column, and the core columns are arranged in sequence from shallow to deep according to the sampling elevation or depth; the white squares on the core column are the section return code labels of the core column sampling, which is equivalent to the core ID code and can be used for core retrieval; the red dots on the side of the core column can be hyperlinks to the detailed geological information of the core, and clicking can perform page jumps or detailed display of the information page; on the right side of the page of the core digital platform can be view buttons for viewing the detailed information of each group and each section of the core, which can quickly browse the core information up or down, or return to the home page; at the bottom of the page of the core digital platform is the quick guide, which can perform functions such as zooming in and out, moving forward and backward. The core information platform can be a network platform integrating relevant introductions of core specimens, and can include multi-source information such as physical core geological information, experimental test information, research progress and research results related to core specimens. The two-dimensional code 150 corresponding to the core information platform can generate a static two-dimensional code picture of the access website of the core information platform corresponding to each section of the core through a two-dimensional code generator. The core information platform and the two-dimensional code can realize the physical connection and real-time interaction between core specimens, natural core objects and digital core information.

[0044] In some embodiments, the flat cylindrical surface 220 of the second semi-cylindrical body 200 may be provided with a fourth groove 240, and the structure of the fourth groove 240 may be the same as that of the third groove 140 in the foregoing embodiments, and the fourth groove 240 is also used to set the two-dimensional code 250 corresponding to the core information platform.

[0045] In the embodiments of the present disclosure, a two-dimensional code can be set on the flat cylindrical surface of one or both of the first semi-cylinder 100 and the second semi-cylinder 200, so as to facilitate obtaining more information of the core. And by forming a groove on the flat cylindrical surface, the wear of the two-dimensional code can be avoided. Setting the two-dimensional code on one of the first semi-cylinder 100 and the second semi-cylinder 200 can reduce the area occupied by the two-dimensional code on the texture feature; setting the two-dimensional code on both the first semi-cylinder 100 and the second semi-cylinder 200 can facilitate the user to obtain more core data through the core information platform when the first semi-cylinder 100 and the second semi-cylinder 200 are separately displayed.

[0046] In some embodiments, the artificial core specimen may be provided with a core label. Among them, as Figure 2 , Figure 3 , Figure 4 , Figure 5 shown, the core label can be set at one to four positions selected from the top surface 160 of the first semi-cylinder, the bottom surface 170 of the first semi-cylinder, the top surface 260 of the second semi-cylinder, and the bottom surface 270 of the second semi-cylinder. The core label can be specific content information or coding information referring to specific content. Through the core label, the following content can be conveniently displayed: geological age information, geological depth information, etc. The setting method of the core label can be directly set in the software before 3D printing and directly generated on the surface of the artificial core specimen through 3D printing, or can be formed on one or more of the top surface 160 of the first semi-cylinder, the bottom surface 170 of the first semi-cylinder, the top surface 260 of the second semi-cylinder, and the bottom surface 270 of the second semi-cylinder by spraying or etching methods. The color of the core label can be different from the color of the core texture, such as red. The font of the core label needs to be regular and clear to facilitate the quick identification, search, and distinction of core information of different geological ages and different depths. In the embodiments of the present disclosure, by setting the core label at one to four positions selected from the top surface 160 of the first semi-cylinder, the bottom surface 170 of the first semi-cylinder, the top surface 260 of the second semi-cylinder, and the bottom surface 270 of the second semi-cylinder, the artificial core specimen can be quickly identified and searched, and the core information of different geological ages and different depths can be effectively distinguished. Selecting one or two positions from the above four different positions to set the core label can reduce the area occupied by the core label on the texture feature to different degrees and ensure that the texture feature is more complete; setting the core label at three or four positions among the above four different positions can record the information of the natural core specimen more comprehensively and can also facilitate observing the core label from different directions.

[0047] In some embodiments, the arc-shaped cylindrical surface 110 of the first semi-cylindrical body 100 or the arc-shaped cylindrical surface 210 of the second semi-cylindrical body 200 may set the height information of the artificial core specimen, or the arc-shaped cylindrical surface 110 of the first semi-cylindrical body 100 and the arc-shaped cylindrical surface 210 of the second semi-cylindrical body 200 may set the height information of the artificial core specimen. The height information of the artificial core specimen refers to the sampling depth of the natural core, including the elevation of the top boundary and the elevation of the bottom boundary of the natural core. The value of the height information can be negative, and the unit can be meters, so as to quickly locate the sampling depth of the core. In the embodiments of the present disclosure, by setting the height information of the artificial core specimen on the surface of the artificial core specimen, the user can conveniently understand the height information of the artificial core specimen, so as to quickly locate the sampling depth of the core.

[0048] Based on the same inventive concept, an exemplary embodiment of the present disclosure further provides a core assembly, such as Figure 6 , Figure 7 , Figure 15 , Figure 16 , Figure 17 shown, may include: a core box 300, and the artificial core specimen may be disposed in the core box 300. The core box 300 may be generally columnar in shape, and the core box 300 may be used for storing and accommodating the artificial core specimen. The size of the core box 300 may be customized according to the sizes of different artificial core specimens to facilitate the size requirements of different artificial core specimens.

[0049] In the embodiments of the present disclosure, by providing a core assembly, the core box 300 and disposing the artificial core specimen in the core box 300, it can be used for the core box 300 to accommodate the artificial core specimen, facilitating the classification, search, and carrying of the artificial core specimen.

[0050] In some embodiments, as Figure 8 shown, the core box 300 may include: a first box body 310 and a second box body 320. The first box body 310 and the second box body 320 may be respectively hollow columnar in shape, and the first box body 310 and the second box body 320 are assembled to form the core box 300. The first box body 310 and the second box body 320, as Figure 11As shown, its interior is hollow and can be provided with a semi-cylindrical cavity 311 and a semi-cylindrical cavity 321, which are respectively identical in shape to the first semi-cylinder 100 and the second semi-cylinder 200, and are respectively used to accommodate the first semi-cylinder 100 and the second semi-cylinder 200. The wall thickness of the first box body 310 and the second box body 320 can be set to 0.5 - 2 cm, and the size of the hollow semi-cylinder can be 1 - 5 mm larger than the diameter and height of the first semi-cylinder 100 or the second semi-cylinder 200 respectively, so that the first semi-cylinder 100 or the second semi-cylinder 200 can be accommodated in the first box body 310 or the second box body 320. The first box body 310 and the second box body 320 can be made by 3D printing. The first box body 310 and the second box body 320 can be solidly printed with a hard material, such as a photosensitive resin material, etc. This kind of material has a relatively large density, rich colors and is durable. Making the core box by 3D printing facilitates the first box body 310 and the second box body 320 to quickly meet the personalized and specific size specification requirements of different artificial core specimens. Such as Figure 9 , Figure 10 , Figure 12 , Figure 14 shown, the outer cylindrical surfaces 312 and 322 of the first box body 310 and the second box body 320 can be set with different colors according to characteristics such as the core geological age information and the core origin, such as blue, green, etc., so that it is convenient to quickly classify and retrieve the artificial core specimens by identifying the core box 300.

[0051] The core box 300 can be made according to the characteristics and storage requirements of artificial core specimens. The main technology that can be adopted is 3D modeling technology. The manufacturing steps of 3D printing can be as follows: The first step is to make the appearance of the core box 300. First, use the "Create - Create Part - Cylinder" tool. Considering the printing tolerance and facilitating the taking and placing of core specimens, create a cylinder that is 1 - 4 mm larger than the size of the core specimen. Use the "Create - Create Part - Cuboid" tool to create two perpendicular and orthogonal cuboids. Use "Tool - Boolean Operation - Union" to merge the two cuboids and the cylinder to obtain a core box appearance that is a cylinder with a right - angled prism. The second step is to open observation holes at the top and bottom of the cylinder. In the software, use the "Create - Create Part - Cylinder" tool to create a cylinder. The diameter of the cylinder can be 5 - 10 mm smaller than the diameter of the core specimen. The size of the cylinder diameter can be modified according to the information that needs to be displayed actually. Use "Tool - Boolean Operation - Subtraction" to subtract the cylinder from the core box appearance obtained in the first step to get a core box with openings at the top and bottom. Load the core specimen to display the core label. The third step is to open a hole on the side of the core box. In the software, use the "Create - Create Part - Cuboid" tool to create a cuboid. The side length of the opening can be 1 - 3 mm. Use "Tool - Boolean Operation - Subtraction" to subtract the cube from the core box appearance obtained in the second step to get a core box with a hole on the side. The fourth step is to set the inside of the box to be hollow. In the software, use the "Create - Create Part - Cylinder" to create a cylinder. The diameter of the cylinder can be 1 - 3 mm longer than the diameter of the core specimen, and the height can be 1 - 3 mm higher. Use "Tool - Boolean Operation - Subtraction" to subtract the cylinder from the core box obtained in the third step to get a hollow core box. Use "Tool - Cutting or Punching" to longitudinally cut the hollow core box along the mid - line and divide the core box into two parts to obtain the core box shell, and the result of setting the hollow can be observed. The formed cavity can be used to place the core specimen. The fifth step is to set the locking line. In the software, use the "Create - Create Part - Cuboid" tool to create a cuboid. Use "Tool - Boolean Operation - Subtraction" to subtract the cylinder in the second step, the cuboid in the third step, and the cylinder in the fourth step from the cuboid in turn to obtain the locking line. Use "Tool - Boolean Operation - Subtraction" with the locking line and one side of the core box to get the concave part in the locking line. Similarly, use "Tool - Boolean Operation - Addition" with the locking line and the other side of the core box to get the convex part in the locking line. Align and fasten the obtained concave and convex parts to make the core box closed. The sixth step is to add text labels. In the software, use "Tool - Identify Plane / Surface" to select the surface to which the text is to be added. Use "Tool - Label" to add the text content to be added.If there is more information to be marked, different contents can be added to different sides of the core box according to requirements; in the seventh step, the model file can be exported for 3D printing. The completed core box model is exported in a certain format and sent to the 3D printer for printing.

[0052] As Figure 8 shown, the second box body 320 is detachably connected to the first box body 310, and can be provided with a semi-cylindrical cavity, which is arranged opposite to the semi-cylindrical cavity 311 of the first box body 310. The second box body 320 and the first box body 310 can be disassembled into two single parts for placing artificial core specimens, or can be connected as a whole. In the connected state, the first box body 310 and the second box body 320 are butted against each other to form a core box 300 for protecting artificial core specimens from wear. The connection method between the second box body 320 and the first box body 310 can be snap connection, screw connection, buckle connection, etc. to achieve convenient disassembly and assembly. The semi-cylindrical cavity 321 of the second box body 320 is arranged opposite to the semi-cylindrical cavity 311 of the first box body 310 to facilitate connection together. As Figure 11 , Figure 13 shown, a hole 313 or a hole 323 can be opened at any one of the mutual connection positions between the second box body 320 and the first box body 310, or a hole 313 and a hole 323 can be opened at the mutual connection positions between the second box body 320 and the first box body 310. The shape of the hole 313 or the hole 323 can be rectangular, and the side length of the rectangle can be 1-3 cm so that a finger can exert force to open the core box 300.

[0053] In the embodiments of the present disclosure, the core box 300 is split in half, and the first box body 310 and the second box body 320 are set to be detachably connected, which can facilitate opening and closing of the core box 300, effectively take and store artificial core specimens, and protect artificial core specimens from wear.

[0054] In some embodiments, as Figure 11 shown, a recess 314 can be provided at the connection position between the first box body 310 and the second box body 320; as Figure 13As shown, a protrusion 324 may be provided at the connection position between the second box body 320 and the first box body 310 for engaging with the recess of the first box body 310 to close the core box 300.
