Description

Technical Field

[0001] This invention relates to the field of basin simulation technology, specifically to a large-scale simulation device and method for differential tectonic deformation in basins. Background Technology

[0002] Differential tectonic deformation in basins refers to the different structural forms and deformation characteristics that occur within and around basins during their formation due to crustal movement, rock compression, or stretching. These deformation characteristics include folds, faults, uplifts, and depressions, which together constitute the complex tectonic system of the basin. Research on differential tectonic deformation in basins is of great significance for understanding basin formation and evolution, revealing the laws governing crustal movement, and identifying oil and gas resources. In-depth research on differential tectonic deformation in basins can reveal the internal structural features, sedimentary environments, and distribution patterns of oil and gas resources, providing important evidence for oil and gas exploration and development. Furthermore, research on differential tectonic deformation in basins also helps to understand the mechanisms and processes of crustal movement, providing a scientific basis for geological hazard prediction and prevention.

[0003] However, existing simulation devices cannot effectively simulate existing basin and basin edge structures, nor can they adjust the size of the simulation range according to the actual simulation situation. Furthermore, during the experiment, vibrations caused by impacts may mix adjacent sand and gravel layers, affecting subsequent slice analysis results and leading to errors in the experimental results.

[0004] Therefore, it is necessary to provide a super-large simulation device for differential tectonic deformation in basins to solve the above problems. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a super-large simulation device for differential tectonic deformation in basins, comprising:

[0006] The support frame has two basin simulation bearing boxes horizontally fixedly mounted on its bottom inner wall. Each basin simulation bearing box has four sets of bearing box force application mechanisms vertically fixedly mounted on the support frame around its perimeter. The upper surface of the support frame has a basin simulation manufacturing mechanism horizontally fixedly mounted on its upper surface.

[0007] There are two mirror-image fluid material carrier tanks, which are fixedly installed on the outside of the support frame on the non-adjacent sides of the two basin simulation carrier tanks.

[0008] On the other two sides of the support frame, solid material bearing boxes and two movable brackets are respectively horizontally arranged, and each movable bracket is fixedly equipped with a high-definition camera.

[0009] The output ends of the solid material carrier box and the two fluid material carrier tanks are all connected to the basin simulation manufacturing mechanism.

[0010] Furthermore, as a preferred embodiment, the basin simulation support box includes:

[0011] The fixed bearing plate is fixedly assembled on the inner wall at the bottom of the support frame;

[0012] The first track has four circumferentially arranged tracks, which are horizontally fixedly mounted on the four sides of the fixed support plate. A second track is slidably mounted on each first track, and a third track is horizontally slidably mounted on the second track. Each third track is perpendicular to the corresponding first track.

[0013] Each of the third tracks is slidably provided with a first sliding block, and each first sliding block is fixedly fitted with a vertical bearing wall.

[0015] Furthermore, as a preferred embodiment, the force-applying mechanism of the bearing box includes:

[0016] The fourth track has two mirror-image configurations, both of which are vertically fixed and mounted on the support frame;

[0017] The fifth track is horizontally slidably mounted on the two fourth tracks, and telescopic columns are horizontally and vertically slidably mounted on the fifth track. Each telescopic column has a force-applying component fixedly mounted on its extended end.

[0018] Furthermore, as a preferred embodiment, among the four bearing box force-applying mechanisms around each basin simulation bearing box, the two opposing bearing box force-applying mechanisms are arranged in a mirror image, and the fourth and fifth tracks of the two adjacent bearing box force-applying mechanisms are arranged perpendicularly.

[0019] Furthermore, preferably, the force-applying component includes:

[0020] A fixed block is fixedly assembled at the extended end of the telescopic column. A universal rotating platform is universally provided at the other end of the fixed block, and multiple adjusting hydraulic cylinders are rotatably provided on the sides adjacent to the fixed block and the universal rotating platform.

[0021] The force range controller is fixedly mounted at the other end of the universal rotating platform.

[0022] Furthermore, preferably, the basin simulation manufacturing mechanism includes:

[0023] The sixth track, which consists of two mirror images, is horizontally and fixedly mounted on the upper end of the support frame. A seventh track is horizontally and vertically slidably arranged between the two sixth tracks.

[0024] A multi-stage telescopic column is vertically slidably mounted on the seventh track, and a spraying manufacturing component is fixedly assembled at the extended end of the multi-stage telescopic column.

[0025] Furthermore, preferably, the spray coating manufacturing assembly includes:

[0026] A drive motor is fixedly mounted on the extended end of the multi-stage telescopic column. A rotating plate is fixedly mounted on the output shaft of the drive motor. Eight sprayers are fixedly mounted on the rotating plate. Two of the sprayers are connected to the corresponding fluid material carrier tanks through material conveying pipes, and the other six sprayers are connected to the solid material carrier box through material conveying pipes.

[0027] Multiple sliding fixing buckles are provided, all of which are fixedly assembled on the multi-stage telescopic column body, and the eight material conveying pipes are slidably arranged on the sliding fixing buckles.

[0028] Furthermore, as a preferred embodiment, the two fluid material carrier tanks respectively carry colloidal materials and polymer materials, and the solid material carrier box is provided with six auxiliary carrier boxes, each carrying five kinds of sand and gravel materials with uniform particle size and different colors, and micro glass materials.

[0029] A method for simulating large-scale differential tectonic deformation in basins includes the following steps:

[0030] S1. Adjust the bearing area of ​​the two basin simulation bearing boxes according to the actual situation;

[0031] S2. A layer of colloidal material is first sprayed onto the bottom of the two basin simulation support boxes by the basin simulation manufacturing mechanism to simulate the development of plastic mantle;

[0032] S3. Several layers of sand and gravel materials of different particle sizes and colors are alternately laid in the sand box to simulate strata from different geological eras;

[0033] S4. Before each change to a different color of sand and gravel, a layer of polymer material is sprayed onto the surface of the sand and gravel layer;

[0034] S5. Lay a layer of micro glass beads according to the actual geological conditions to simulate the development of detached strata;

[0035] S6. Two basin simulation bearing boxes simulate the differences in stratigraphic development between different basins or different tectonic units within the same basin by setting different combinations of variables such as the number, thickness, and color of sand layers, as well as conditions such as whether or not a micro glass bead detachment layer is laid.

[0036] S7. The bearing box force application mechanism can control the force application component to hit the basin simulation bearing box at a certain speed to simulate plate collision. The force application component can adjust the angle to adjust the impact angle. At the same time, the bearing box force application mechanism can control the force application component to apply force to the basin simulation bearing box to simulate plate rotation.

[0037] S8. During the experiment, a high-definition camera was used to take pictures at regular intervals to record the structural deformation caused during the continuous convergence and collision process;

[0038] S9. After the experiment, the sand body was sliced ​​and observed to analyze the tectonic deformation characteristics within the basin. The coupling response relationship between the rotational change of the angle during plate convergence and collision and the differential tectonic deformation between different basins or different tectonic units within the same basin was obtained.

[0039] Compared with the prior art, the present invention provides a super-large simulation device and method for differential tectonic deformation in basins, which has the following beneficial effects:

[0040] In this invention, during the actual experiment, the device needs to be set up in a relatively closed environment, and the experimental conditions, such as temperature and humidity, must be strictly controlled to ensure the accuracy and reliability of the experimental results and to avoid interference from external factors. The setting of two basin simulation carrier boxes can form a comparison to analyze the differences in tectonic deformation generated during the convergence and collision of different basins or different tectonic units in the same basin, including the formation and evolution of geological structures such as faults and folds. At the same time, the internal volume of the basin simulation carrier box can be adjusted according to the actual situation to adapt to basins of different sizes.

[0041] In this invention, the bearing box force application mechanism can control the component to impact the basin simulation bearing box at a certain speed, simulating plate collision. The bearing box force application mechanism can adjust the impact angle and control the component to apply force to the basin simulation bearing box to simulate plate rotation. This allows for precise control of various parameters during the simulation process, ensuring the accuracy of the simulation results. The telescopic column can apply force instantaneously to simulate impacts of different intensities. Simultaneously, the force application range controller can adjust the contact range by extending and retracting, thereby maximizing the simulation of basin impact and compression, ensuring the accuracy of the simulation results.

[0042] In this invention, the basin simulation manufacturing mechanism can simulate the actual basin conditions through spraying, thereby maximizing the realism of the basin simulation. Furthermore, the spraying manufacturing component can control the spraying speed and efficiency for targeted spraying, simulating the conditions of different layers of the basin with varying undulations, thus accurately simulating the basin conditions and further improving the accuracy and effectiveness of the experimental results. It is equipped with eight sprayers, each with a different internal structure, to spray different materials. Simultaneously, the spraying position of the working sprayer can be adjusted by rotating the rotating plate via a drive motor, avoiding any spraying dead zones and further ensuring the basin simulation. The sliding fixing buckle can restrain the material conveying pipe and ensure the connection between the sprayer and the material conveying pipe when the multi-stage telescopic column extends.

[0043] In this invention, the solid material carrier box and the two fluid material carrier tanks respectively carry the fluid and solid materials required for the construction of the basin, thereby providing raw material support for the basin simulation manufacturing mechanism to construct the basin. In addition, a new polymer material is provided, which can be formed into a dense film through a spraying process. The film usually has excellent waterproof and sandproof properties, which can effectively block the sand layer. At the same time, the film has a certain degree of extensibility, which can adapt to the slight deformation of the substrate, and does not have significant elasticity, so it will not bounce back to the sand layer after the sand layer deforms, thus causing deviation in the experimental results.

[0051] Please see Figures 1-6 This invention provides a super-large simulation device for differential tectonic deformation in basins, comprising:

[0052] The support frame 1 has two basin simulation bearing boxes 2 horizontally fixedly mounted on its bottom inner wall. Each basin simulation bearing box 2 has four sets of bearing box force application mechanisms 3 vertically fixedly mounted on the support frame 1 around its perimeter. The support frame 1 has a basin simulation manufacturing mechanism 4 horizontally fixedly mounted on its upper surface. Stress monitoring equipment is evenly set inside the box.

[0053] There are two mirror-image fluid material carrier tanks 6, which are fixedly installed on the outside of the support frame 1 on the non-adjacent sides of the two basin simulation carrier boxes 2.

[0054] On the other two sides of the support frame 1, a solid material bearing box 5 and two movable brackets 7 are respectively horizontally arranged, and a high-definition camera 8 is fixedly mounted on each movable bracket 7.

[0055] The output ends of the solid material carrier box 5 and the two fluid material carrier tanks 6 are all connected to the basin simulation manufacturing mechanism 4.

[0056] As a preferred embodiment, in the actual experiment, the device needs to be set up in a relatively closed environment, and the experimental conditions (such as temperature and humidity) need to be strictly controlled to ensure the accuracy and reliability of the experimental results and avoid interference from external factors. The setting of two basin simulation bearing boxes 2 can form a comparison to analyze the differences in tectonic deformation generated during convergence and collision of different basins or different tectonic units in the same basin, including the formation and evolution of geological structures such as faults and folds. At the same time, the basin simulation bearing box 2 can adjust its internal volume according to the actual situation to adapt to basins of different sizes. The bearing box force application mechanism 3 can control the component to collide with the basin simulation bearing box 2 at a certain speed to simulate plate collision. The bearing box force application mechanism 3 can adjust the impact angle and control the component to collide with the basin model. The simulated bearing box 2 applies force to simulate the rotation of the plate, thereby precisely controlling various parameters in the simulation process to ensure the accuracy of the simulation results. The basin simulation manufacturing mechanism 4 can simulate the basin by spraying according to the actual basin conditions, thereby accurately simulating the basin conditions and further improving the accuracy and effectiveness of the experimental results. The solid material bearing box 5 and the two fluid material bearing tanks 6 respectively carry the fluid and solid materials required for basin manufacturing, thereby providing raw material support for the basin simulation manufacturing mechanism 4 to manufacture the basin. The high-definition camera 8 takes pictures at regular intervals to record the structural deformation caused during the continuous convergence and collision process, providing technical support for subsequent analysis. The movable bracket 7 can adjust the shooting angle of the high-definition camera 8 according to the actual basin simulation conditions, thereby obtaining clearer and more effective data.

[0057] Furthermore, the basin simulation support box 2 includes:

[0058] The fixed bearing plate 21 is fixedly assembled on the inner wall at the bottom of the support frame 1;

[0059] The first track 22 has four circumferentially arranged tracks, which are horizontally fixedly mounted on the four sides of the fixed bearing plate 21. Each first track 22 is slidably mounted with a second track 23, and a third track 24 is horizontally slidably mounted on the second track 23. Each third track 24 is perpendicular to the corresponding first track 22.

[0060] Each of the third tracks 24 is slidably provided with a first sliding block 25, and each of the first sliding blocks 25 is fixedly assembled with a vertical bearing wall 26.

[0061] Furthermore, the four vertical support walls 26 are staggered, with one end of each vertical support wall 26 in sliding contact with the inner side of the adjacent vertical support wall 26, and the inner side of the vertical support wall 26 in sliding contact with one end of another set of vertical support walls 26 adjacent to it, and all four vertical support walls 26 are made of transparent material.

[0062] In a preferred embodiment, the four vertical bearing walls 26 enclose a basin-making container, and the volume of the container can be adjusted according to the actual situation to ensure the simulation of the basin. At the same time, there are certain gaps between the four third tracks 24 and the vertical bearing walls 26, which can ensure that the vertical bearing walls 26 can transmit forces. Since the bottom needs to be laid with colloidal material to simulate the development of plastic mantle, the existence of gaps will not cause sand and gravel leakage, thus preventing the experiment from failing.

[0063] Furthermore, the force-applying mechanism 3 of the bearing box includes:

[0064] The fourth track 31 has two mirror images, both of which are vertically fixed and assembled on the support frame 1;

[0065] The fifth track 32 is horizontally slidably mounted on the two fourth tracks 31, and a telescopic column 33 is horizontally and vertically slidably mounted on the fifth track 32. Each telescopic column 33 is fixedly mounted with a force application component 34 at its extended end.

[0066] In a preferred embodiment, the fourth track 31 and the fifth track 32 can drive the telescopic column 33 to move to various positions, thereby facilitating the adjustment of the impact and compression positions. The telescopic column 33 can exert force instantaneously, thereby simulating impacts of different intensities.

[0067] Furthermore, among the four bearing box force application mechanisms 3 on the periphery of each basin simulation bearing box 2, the two opposing bearing box force application mechanisms 3 are arranged in a mirror image, and the fourth track 31 and the fifth track 32 of the two adjacent bearing box force application mechanisms 3 are arranged perpendicularly.

[0068] In a preferred embodiment, the four bearing box force application mechanisms 3 are positioned such that each bearing box force application mechanism 3 avoids mutual interference during the process of applying force to the basin simulation bearing box 2 to simulate impact and compression, thereby further ensuring the efficiency and accuracy of the experiment, while protecting the device and preventing damage.

[0069] Furthermore, the force-applying component 34 includes:

[0070] The fixing block 341 is fixedly assembled at the extended end of the telescopic column 33. The other end of the fixing block 341 is universally provided with a universal rotating platform 342, and multiple adjusting hydraulic cylinders 343 are rotatably provided on the adjacent sides of the fixing block 341 and the universal rotating platform 342.

[0071] The force range controller 344 is fixedly mounted at the other end of the universal rotating platform 342;

[0072] In a preferred embodiment, the adjusting hydraulic cylinders 343 can adjust the actual angle of the universal rotating platform 342 by extending or shortening each other, thereby adjusting the actual angle between the force range controller 344 and the basin simulation bearing box 2, thus simulating different impact and compression angles, further ensuring the accuracy and precision of the experiment. At the same time, the force range controller 344 can adjust the contact range by extending and contracting, thereby maximizing the simulation of basin impact and compression conditions, ensuring the accuracy of the simulation results.

[0073] Furthermore, the basin simulation manufacturing mechanism 4 includes:

[0074] The sixth track 41 has two mirror images, both horizontally fixedly assembled to the upper end of the support frame 1, and a seventh track 42 is horizontally and vertically slidably arranged between the two sixth tracks 41.

[0075] A multi-stage telescopic column 43 is vertically slidably mounted on the seventh track 42, and a spraying manufacturing component 44 is fixedly assembled at the extended end of the multi-stage telescopic column 43.

[0076] In a preferred embodiment, the sixth track 41 and the seventh track 42 can drive the multi-stage telescopic column 43 to move, thereby driving the spraying manufacturing component 44 to spray materials at various positions inside the basin simulation support box 2, thereby maximizing the realism of the basin simulation. Furthermore, the spraying manufacturing component 44 can perform targeted spraying by controlling the spraying speed and spraying efficiency, thereby simulating the conditions of different layers of the basin with varying undulations.

[0077] Furthermore, the spray coating manufacturing assembly 44 includes:

[0078] A drive motor 441 is fixedly mounted on the extended end of the multi-stage telescopic column 43. A rotating plate 442 is fixedly mounted on the output shaft of the drive motor 441. Eight sprayers 443 are fixedly mounted on the rotating plate 442. Two of the sprayers 443 are connected to the corresponding fluid material carrier tank 6 through a material conveying pipe 444, and the other six sprayers 443 are connected to the solid material carrier box 5 through a material conveying pipe 444.

[0079] Multiple sliding fixing buckles 445 are provided, all of which are fixedly assembled on the multi-stage telescopic column 43, and the eight material conveying pipes 444 are slidably arranged on the sliding fixing buckles 445.

[0080] In a preferred embodiment, the eight sprayers 443 have different internal structures to perform spraying of different materials. At the same time, the spraying position of the working sprayer 443 can be adjusted by rotating the rotating plate 442 through the drive motor 441, thereby avoiding the existence of spraying dead corners and further ensuring the basin simulation. The sliding fixing buckle 445 can restrain the material conveying pipe 444 and ensure the connection between the sprayer 443 and the material conveying pipe 444 when the multi-stage telescopic column 43 is extended.

[0081] Furthermore, the two fluid material carrier tanks 6 respectively carry colloidal materials and polymer materials, and the solid material carrier box 5 is provided with six auxiliary carrier boxes, which respectively carry five kinds of sand and gravel materials with uniform particle size and different colors and micro glass materials.

[0082] As a preferred embodiment, the fluid silicone material can be sprayed to simulate the development of the actual undulating plastic mantle, avoiding the difficulty in manufacturing pre-formed silicone materials in traditional devices. Five kinds of sand and gravel materials with uniform particle size and different colors can simulate strata of different geological eras and are easy to observe. The microglass material can simulate the development of detached strata, further ensuring the simulation of the basin. The new polymer material can be sprayed to form a dense film. The film usually has excellent waterproof and sandproof properties, which can effectively block the sand layer. At the same time, the film has a certain degree of extensibility, which can adapt to the small deformation of the substrate, and does not have significant elasticity, so it will not bounce back to the sand layer after deformation, thus causing deviation in the experimental results.

[0083] A method for simulating large-scale differential tectonic deformation in basins includes the following steps:

[0084] S1. Adjust the bearing area of ​​the two basin simulation bearing boxes 2 according to the actual situation;

[0085] S2. A layer of colloidal material is first sprayed onto the bottom of the two basin simulation support boxes 2 by the basin simulation manufacturing mechanism 4 to simulate the development of plastic mantle;

[0086] S3. Several layers of sand and gravel materials of different particle sizes and colors are alternately laid in the sand box to simulate strata from different geological eras;

[0087] S4. Before each change to a different color of sand and gravel, a layer of polymer material is sprayed onto the surface of the sand and gravel layer;

[0088] S5. Lay a layer of micro glass beads according to the actual geological conditions to simulate the development of detached strata;

[0089] S6. Two basin simulation bearing boxes 2 simulate the differences in stratigraphic development between different basins or different tectonic units within the same basin by setting different combinations of variables such as the number, thickness, and color of sand layers, as well as conditions such as whether or not a micro glass bead slip layer is laid.

[0090] S7. The bearing box force application mechanism 3 can control the force application component 34 to collide with the basin simulation bearing box 2 at a certain speed to simulate plate collision. The force application component 34 can adjust the angle to adjust the impact angle. At the same time, the bearing box force application mechanism 3 can control the force application component 34 to apply force to the basin simulation bearing box 2 to simulate plate rotation.

[0091] S8. During the experiment, a high-definition camera 8 was used to take pictures at regular intervals to record the structural deformation caused during the continuous convergence and collision process;

[0092] S9. After the experiment, the sand body was sliced ​​and observed to analyze the tectonic deformation characteristics within the basin.

Two basin simulation bearing boxes (2) simulate the differences in stratigraphic development between different basins or different tectonic units in the same basin by setting different combinations of variables such as the number, thickness, and color of sand layers, as well as whether or not micro glass bead slip layers are laid. S7. The bearing box force application mechanism (3) can control the force application component (34) to hit the basin simulation bearing box (2) at a certain speed to simulate plate collision. The force application component (34) can adjust the angle to adjust the impact angle. At the same time, the bearing box force application mechanism (3) can control the force application component (34) to apply force to the basin simulation bearing box (2) to simulate plate rotation. S8. During the experiment, a high-definition camera (8) was used to take pictures at regular intervals to record the structural deformation caused during the continuous convergence and collision process; S9. After the experiment, the sand body was sliced ​​and observed to analyze the tectonic deformation characteristics within the basin. The coupling response relationship between the rotational change of the angle during plate convergence and collision and the differential tectonic deformation between different basins or different tectonic units within the same basin was obtained.
