[0047] The accompanying drawings have illustrated specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0048] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0049] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, data stored, data displayed, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties. Furthermore, the collection, use and processing of the relevant data must comply with relevant laws, regulations and standards, and corresponding operation entry points are provided for users to choose to authorize or refuse.

[0050] Sedimentary basins (also known as sedimentary strata) contain abundant resources, and studying the filling process of sedimentary basins is an important aspect of geology. The filling process of sedimentary basins is often dominated by river-deltaic systems: rivers transport sediments from upstream to the coastline or lake shoreline, forming deltas. The resulting accumulation of sediments or the superposition of sedimentary strata forms the main units of sedimentary basin filling. In this process, external dynamic conditions such as tectonic movements (e.g., uplift or tilting), the supply of upstream sediments, and the rise and fall of sea (or lake) levels collectively control the superposition of sedimentary strata. Therefore, understanding how the superposition of sedimentary strata responds to external driving conditions is a core task in sedimentary strata research.

[0051] Currently, the most intuitive method for visually demonstrating the stacking process of sedimentary strata is the flume experiment. A flume experiment involves creating an artificial slope within a pool filled with water, with part of the slope above the water surface and part submerged. Sediments and water are poured into the pool from a point on the slope. Over time, the sediment accumulates, gradually filling the underwater space, thus simulating the filling process of a sedimentary basin.

[0052] However, the aforementioned flume experiments primarily simulate the stacking process of sedimentary strata in three-dimensional space, meaning the experimental results obtained are three-dimensional sedimentary bodies. If a more in-depth study of the internal stratigraphic stacking process within the sedimentary body is required, the three-dimensional sedimentary body needs to be sliced ​​after the experiment to analyze the internal interfaces and stacking relationships of the strata at different time points.

[0053] It is understandable that existing flume experiments cannot record and demonstrate the dynamic evolution of sedimentary profiles over time in real time during the experiment. Moreover, the sedimentary body can only be cut and segmented after the flume experiment to study its internal structure. In addition, studying two-dimensional profiles of three-dimensional sedimentary bodies by slicing inevitably damages the experimental results.

[0054] Therefore, simulating the stacking process of sedimentary strata faces the problem of poor accuracy.

[0055] This application provides a method, apparatus, device, and medium for determining the superposition process of sedimentary strata. The method is applied to a superposition process simulation device, which includes an outer water tank and an inner water tank. The inner water tank is located inside the outer water tank, and its front view is a parallelogram. The liquid in the inner water tank is connected to the liquid in the outer water tank. A water-sediment mixture flows into the inner water tank through a preset position at the top. The method controls the flow of the water-sediment mixture into the inner water tank. Furthermore, according to a preset image acquisition cycle, it acquires the front view of the inner water tank at different times, and determines the superposition process information of the sedimentary strata in the inner water tank based on the front view of the inner water tank at each time. The water-sediment mixture includes fluid and sediment. The front view of the inner water tank represents the distribution of sediment and fluid in the inner water tank. The sedimentary strata represent the strata composed of sediment in the water-sediment mixture, and the superposition process information represents the process by which sediment forms the sedimentary strata. By flowing a water-sediment mixture into the inner flume, frontal views of the inner flume at different times can be obtained. These views reveal the distribution of sediment and fluid within the flume, and consequently, the process by which sediment forms sedimentary strata. This avoids the disruption of experimental results caused by slicing three-dimensional sedimentary bodies into two-dimensional profiles, a problem present in existing techniques. The method for determining the superposition process of sedimentary strata provided in this application improves the accuracy of simulating the superposition process of sedimentary strata.

[0056] The technical solution of this application and how it solves the above-mentioned technical problems will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0057] Figure 1 A schematic diagram of the structure of a stacking process simulation device provided in this application Figure 1 ,like Figure 1 As shown, from a frontal view, the stacking process simulation device includes an outer water tank and an inner water tank.

[0058] The inner water tank is located inside the outer water tank. The front view of the inner water tank is a parallelogram. The liquid in the inner water tank is connected to the liquid in the outer water tank. The water-sand mixture flows into the inner water tank through a preset position at the top of the inner water tank.

[0059] The outer water tank can be a rectangular transparent tank made of glass, such as tempered glass. By making the outer water tank transparent, users or staff can easily observe the inside of the outer water tank.

[0060] In one possible implementation, the outer water tank can be a rectangular transparent water tank that is 9 meters long, 0.8 meters wide, and 1.1 meters high.

[0061] The front view of the inner water tank is a parallelogram. The inner water tank can be a transparent hexahedron. The six sides of the inner water tank can be made of acrylic sheets or other transparent materials. Making the inner water tank transparent is to facilitate users or staff to observe the inside of the inner water tank.

[0062] In one possible implementation, the top of the outer water tank can be empty. The advantage of this setting is that it ensures that the pressure of the outer water tank, the inner water tank and the outside environment are consistent, so as to ensure the accuracy of simulating the stacking process of sedimentary strata.

[0063] In one possible implementation, the inner water tank is located at the center inside the outer water tank so that the user or staff can fully and clearly observe the inner water tank from the outer water tank.

[0064] To better describe the inner water tank, Figure 2 A schematic diagram of the structure of the inner water tank in a stacking process simulation device provided in this application. Figure 1 ,like Figure 2 As shown, from a frontal view, the inner water tank may include two identical parallelogram plates, and a top plate, bottom plate, side top plate, and side bottom plate that connect the two identical parallelogram plates as a hexahedron.

[0065] Among them, two identical parallelogram plates are parallel to each other, and the long side of the two identical parallelogram plates is parallel to the bottom surface of the outer water tank.

[0066] It is understood that the distance between two identical parallelogram plates is the same as the width of the top plate, bottom plate, side top plate, or side bottom plate. For example, the distance between two identical parallelogram plates is 2 cm, and the width of the top plate, bottom plate, side top plate, or side bottom plate is also 2 cm.

[0067] Both the bottom plate and the top plate are parallel to the bottom surface of the outer water tank, and the distance between the bottom plate and the bottom surface of the outer water tank is less than the distance between the top plate and the bottom surface of the outer water tank.

[0068] The angle between the side bottom plate and the bottom plate is obtuse, the angle between the side top plate and the bottom plate is acute, and the side top plate is parallel to the side bottom plate.

[0069] The side and top plates are open to allow the liquid in the inner tank to communicate with the liquid in the outer tank, meaning the water level in the inner tank is the same as the water level in the outer tank.

[0070] For example, the openness of the side top plate and the top plate can be ensured by creating holes in them.

[0071] Meanwhile, an opening is provided at a predetermined position at the top of the inner water tank, that is, at a predetermined position on the top plate of the inner water tank, so that the water-sand mixture can flow into the inner water tank from the opening.

[0072] For example, the aforementioned preset position is close to the side bottom plate so that after the water-sand mixture flows into the inner water tank through the preset position at the top of the inner water tank, the silt in the water-sand mixture accumulates along the side bottom plate to the bottom of the inner water tank, so as to accurately simulate the silt accumulation process.

[0073] In one possible implementation, the bottom plate and side bottom plates are grooved. Grooving can be understood as cutting the surfaces of the bottom plate and side bottom plates inside the inner water tank to form grooves on the surfaces of the bottom plate and side bottom plates. This enhances the friction between the surfaces of the bottom plate and side bottom plates, allowing the water-sand mixture to flow into the inner water tank from a predetermined position at the top, which conforms to the natural process of sedimentary strata stacking.

[0074] For example, the grooves on the surfaces of the bottom plate and side bottom plate after grooving can be equally spaced grooves. The length of the groove can be the width of the bottom plate or side bottom plate, for example, 2 cm. The width of the groove can be 4 mm, the depth of the groove can be 2 mm, and the spacing between the grooves can be 7 mm.

[0075] To better describe the inner water tank, Figure 3 A schematic diagram of the structure of the inner water tank in a stacking process simulation device provided in this application. Figure 2 ,like Figure 3 As shown, according to Figure 3 Viewed from the perspective indicated by the arrow, the inner water tank may consist of at least two identical parallelogram panels, namely parallelogram panel 1 and parallelogram panel 2. The top plate, bottom plate, side top plate, and side bottom plate of the inner water tank support these two identical parallelogram panels. It should be noted that the numbering of parallelogram panels 1 and 2 is merely for indicating the quantity of parallelogram panels; these two parallelogram panels are otherwise identical.

[0076] Among them, the viewing angle in the direction of the arrow can be: the angle between the arrow and the base plate is 45 degrees, the angle between the arrow and the direction of gravity is 45 degrees, and the angle between the arrow and any parallelogram plate is 45 degrees.

[0077] To ensure the openness between the side and top panels, gaps are provided in both the side and top panels.

[0078] For example, the specifications of the gaps in the side top plate can be that the length is 20 cm, the width is the width of the side top plate, the multiple gaps in the side top plate are equally spaced, and the closest distance between the gaps is 2 cm.

[0079] The specifications for the gaps in the top plate can be as follows: the length is 11.5 cm, the width is the same as the width of the side top plate, the multiple gaps in the top plate are equally spaced, and the closest distance between the gaps is 5.5 cm.

[0080] It is understood that the superposition process simulation device provided in this application allows a water-sediment mixture to flow into the inner water tank through a preset position at the top of the inner water tank, and the distribution of water and sediment in the water-sediment mixture in the inner water tank can be directly observed from a perspective looking directly at the inner water tank. The superposition process simulation device provided in this application can be used to improve the accuracy of simulating the superposition process of sedimentary strata.

[0081] In one alternative implementation, Figure 4 A schematic diagram of the structure of a stacking process simulation device provided in this application Figure 2 ,like Figure 4 As shown, the stacking process simulation device also includes a hose, which is used to connect the inner water tank, the water tank, and the sediment tank. Fluid in the water tank flows into the inner water tank through the hose, and sediment in the sediment tank flows into the inner water tank through the hose.

[0082] The stacking process simulation device also includes a funnel connected to a hose. Fluid in the water tank flows into the hose through the funnel, and sediment in the sediment tank flows into the hose through the funnel.

[0083] The hose can be used to connect the inner water tank with the water tank and the sediment tank, so that the fluid in the water tank and the sediment in the sediment tank can flow smoothly into the inner water tank, thereby providing a material basis for the formation of sedimentary strata.

[0084] For example, the hose can be a transparent tube so that users or staff can observe the inside of the hose.

[0085] It is understandable that the fluid in the water tank flows into the inner water tank through a hose, which allows for precise control of the fluid flow rate and velocity, simulating the impact of different water flow conditions on the stacking process of sedimentary strata.

[0086] In one possible implementation, a valve is installed at the hose. By adjusting the opening and closing of the valve, the changes in water flow during flood and dry seasons can be simulated, thereby observing the formation characteristics of sedimentary strata under different water flow conditions.

[0087] Meanwhile, the sediment in the sediment tank flows into the inner water tank through a hose, achieving quantitative transport and uniform distribution of the sediment.

[0088] The funnel is connected to a hose so that the fluid in the water tank and the sediment in the sediment tank both pass through the funnel first, then through the hose, and finally through the hose into the inner water tank.

[0089] It's understandable that the funnel, connected to the hose, guides and buffers the fluid and sediment. Specifically, for fluid in the water tank, the funnel smoothly guides the fluid into the hose, preventing excessive turbulence or splashing as it flows in, thus ensuring a stable fluid delivery. Similarly, for sediment in the sediment tank, the funnel allows it to flow smoothly through the hose into the inner water tank, preventing blockage or accumulation at the hose inlet and ensuring a smooth sediment supply.

[0090] The superposition process simulation device provided in this application allows fluid and sediment to flow steadily into the inner water tank through the coordinated operation of a hose and a funnel, thereby enabling the superposition process simulation device to more accurately simulate actual deposition conditions and improve the accuracy of simulating the superposition process of sedimentary strata.

[0091] Figure 5 A flowchart illustrating a method for determining the superposition process of sedimentary strata provided in this application. Figure 1 This method can be applied to a stacking process simulation device, which includes an outer water tank and an inner water tank. The inner water tank is located inside the outer water tank, and its front view is a parallelogram. The liquid in the inner water tank is connected to the liquid in the outer water tank. The water-sand mixture flows into the inner water tank through a preset position at the top. The execution subject of this method can be a stacking process simulation device, a server, a host, or other equipment, such as... Figure 5 As shown, the method may include:

[0092] S501, Control the flow of water-sand mixture into the inner water tank; wherein, the water-sand mixture includes fluid and silt.

[0093] Among them, water-sand mixture can refer to a mixture of fluid and sediment, where fluid can refer to natural water and sediment can refer to solid particles of various sizes.

[0094] Controlling the flow of the water-sand mixture into the inner water tank can be understood as flowing the water-sand mixture into the inner water tank at a certain rate.

[0095] In one optional implementation, step S501 may include:

[0096] According to a preset first rate, the fluid in the water tank is controlled to flow into the funnel, and according to a preset second rate, the sediment in the sediment tank is controlled to flow into the funnel; wherein, the funnel flows the water-sand mixture into the inner water tank through a hose.

[0097] The preset first rate can refer to the rate set by the operator, which can be the rate at which fluid flows from the water tank into the funnel. Similarly, the preset second rate can refer to the rate set by the operator, which can be the rate at which sediment from the sediment tank flows into the funnel.

[0098] It is understandable that the flow of fluid from the tank into the funnel is controlled according to a preset first rate. The first rate can be set by the operator based on the sedimentation environment designed for the experiment. For example, to simulate a fast-flowing river environment, the first rate can be set to a larger value; to simulate a still lake environment, the first rate can be set to a smaller value.

[0099] Similarly, the flow of sediment from the sediment tank into the funnel is controlled according to a preset second rate. This second rate can be determined by the staff based on the sedimentation environment and research objectives.

[0100] For example, in a scenario simulating a river-delta system, the preset first rate can be... (cubic centimeters per second), the preset second rate can be If the density of the sediment in the sediment tank is (grams per cubic centimeter), then the preset second rate can also be expressed as (grams per second).

[0101] It can be understood that by controlling the preset first rate and the preset second rate, the rate at which the water-sand mixture, composed of fluid and sediment, flows into the inner water tank can be determined. The rate at which the water-sand mixture flows into the inner water tank can be considered as the gravitational rate of the water-sand mixture passing through the funnel and in the hose, and flowing into the inner water tank at the gravitational rate, where the gravitational rate can refer to the rate at which the water-sand mixture falls freely in the hose.

[0102] The beneficial effect of this setup is that by precisely controlling the flow of the water-sand mixture into the inner water tank, specifically by precisely controlling the rate at which the fluid in the water tank flows into the funnel and the rate at which the sediment in the sediment tank flows into the funnel, it is possible to simulate the fluid and sediment movement states under various natural sedimentary environments. This improves the accuracy of simulating the superposition process of sedimentary strata and provides experimental evidence for geological research.

[0103] In one possible implementation, a switch is provided between the funnel and the hose; the method may also include:

[0104] The weight of the water-sand mixture in the funnel is monitored in real time. If the weight exceeds the preset weight threshold, the switch between the funnel and the hose is opened, allowing the water-sand mixture to flow into the inner water tank through the hose.

[0105] One of the methods is to use a weight sensor to monitor the weight of the water-sand mixture in the funnel in real time.

[0106] A solenoid valve can be installed between the funnel and the hose. When the weight sensor detects that the weight of the water-sand mixture in the funnel exceeds a preset weight threshold, the solenoid valve can be opened, allowing the water-sand mixture to flow into the inner water tank through the hose.

[0107] The preset weight threshold can be a weight threshold for the water-sand mixture set by the staff. For example, the weight threshold can be set to 0.2 grams. When the weight sensor detects that the weight of the water-sand mixture in the funnel exceeds 0.2 grams, the solenoid valve can be opened, allowing the water-sand mixture to flow into the inner water tank through the hose.

[0108] The advantage of this setup is that it avoids interference from other factors that could affect the determination of the depositional strata stacking process when the fluid in the water tank and the sediment in the sediment tank do not flow into the funnel in time.

[0109] S502. According to the preset image acquisition cycle, acquire the front view of the inner water tank at different times; wherein, the front view of the inner water tank represents the distribution of silt and fluid in the inner water tank.

[0110] The preset image acquisition cycle can refer to the image acquisition cycle set in advance by the staff, that is, the cycle for acquiring the front view of the inner water tank.

[0111] For example, the preset image acquisition period can be 30 seconds, that is, a front view of the inner water tank is acquired once every 30 seconds.

[0112] In one possible implementation, a pre-set image acquisition device, such as a digital camera or camcorder, can be used to acquire the front view of the inner water tank at different times. If the pre-set image acquisition device is a camcorder and the camcorder has sufficient memory, the front view of the inner water tank at different times can be recorded within a preset time period.

[0113] In this process, it is necessary to ensure that the image acquisition device is fixed in an appropriate position, such as 1 meter away from the outer water tank, and that the image acquisition device can be directly facing the front view of the inner water tank in order to obtain a complete and clear front view of the inner water tank.

[0114] In an optional implementation, step S502 may include:

[0115] According to the preset image acquisition cycle, a preset volume of coal powder is fed from the funnel into the inner water tank through a preset coal powder feeding device; and a preset image acquisition device is used to acquire a front view of the inner water tank.

[0116] Coal powder can refer to fine particulate matter that is black or dark gray.

[0117] In the method for determining the superposition process of sedimentary strata in this application, coal powder can be used to simulate the stratigraphic interface. As the water-sediment mixture flows from the funnel into the inner water tank and a predetermined volume of coal powder flows from the funnel into the inner water tank, the distribution of coal powder in the inner water tank can be simulated as the movement state of the stratigraphic interface.

[0118] The preset coal powder dispensing device can refer to a pre-set coal powder dispensing device. For example, the coal powder dispensing device can be a plastic bottle. The plastic bottle is inverted, and the bottle cap of the plastic bottle is provided with uniform openings. According to the preset image acquisition cycle, by squeezing the bottle body twice, the coal powder in the bottle body flows out from the bottle cap and flows from the funnel into the inner water tank.

[0119] The preset volume can refer to the volume of coal powder that flows out of the bottle cap after the plastic bottle is squeezed twice. For example, the preset volume can be 1.4 cubic centimeters. If the density of coal powder is 1.43 grams per cubic centimeter, then the weight of coal powder is 2 grams.

[0120] According to a preset image acquisition cycle, such as every 30 seconds, the step of delivering a preset volume of coal powder from the funnel into the inner water tank via a preset coal powder delivery device is executed.

[0121] The advantage of this setup is that by controlling the amount and frequency of coal powder input, the movement state of the stratigraphic interface of sedimentary strata in a natural environment can be simulated, thereby improving the accuracy of simulating the superposition process of sedimentary strata.

[0122] S503. Based on the front view of the inner flume at each time point, determine the superposition process information of the sedimentary strata in the inner flume; wherein, the sedimentary strata represent the strata composed of mud and sand in the water-sand mixture, and the superposition process information represents the process by which mud and sand form the sedimentary strata.

[0123] Among them, the information on the superposition process of sedimentary strata in the inner flume can refer to the process by which the sediment in the water-sand mixture forms sedimentary strata.

[0124] By observing the frontal views of the inner flume at various times, it can be understood that the frontal views record the distribution of sediment and fluid in the inner flume. By observing the frontal views of the inner flume at various times, it is possible to infer how sediment gradually accumulates to form strata.

[0125] For example, features including but not limited to changes in the thickness of sedimentary strata, morphological characteristics of sedimentary strata, and sedimentary sequence of sedimentary strata can be analyzed from the front view of the inner flume at various times.

[0126] The method for determining the superposition process of sedimentary strata provided in this application controls the inflow of a water-sediment mixture into an inner flume. Further, according to a preset image acquisition cycle, it acquires frontal views of the inner flume at different times, and determines the superposition process information of sedimentary strata within the inner flume based on these frontal views. The water-sediment mixture includes fluids and sediment. The frontal view of the inner flume represents the distribution of sediment and fluid within the flume, the sedimentary strata represent the strata composed of sediment from the water-sediment mixture, and the superposition process information represents the process by which sediment forms the sedimentary strata. By infusing the water-sediment mixture into the inner flume, frontal views of the inner flume at different times can be obtained, allowing for an understanding of the distribution of sediment and fluid within the flume. This, in turn, reveals the process by which sediment forms the sedimentary strata, avoiding the damage to experimental results caused by slicing three-dimensional sedimentary bodies into two-dimensional profiles, as is common in existing technologies. The method for determining the superposition process of sedimentary strata provided in this application improves the accuracy of simulating the superposition process of sedimentary strata.

[0127] In one alternative implementation, Figure 6 A schematic diagram of the structure of a stacking process simulation device provided in this application Figure 3 ,like Figure 6 As shown, the stacking process simulation device includes a bidirectional pump and a water storage tank, with the bidirectional pump positioned between the outer water tank and the water storage tank.

[0128] In one alternative embodiment, the stacking process simulation device further includes an electromagnetic flow meter disposed between the outer water tank and the bidirectional pump.

[0129] The bidirectional pump can refer to a pump capable of operating in both directions. For example, a bidirectional pump can pump fluid from container A to container B, or vice versa. In the stacking process simulation apparatus, the bidirectional pump is positioned between the outer water tank and the reservoir, allowing fluid to be pumped from the outer water tank to the reservoir, or vice versa. Specifically, configuring the bidirectional pump to pump fluid from the outer water tank to the reservoir simulates downstream flow conditions, while configuring it to pump fluid from the reservoir to the outer water tank simulates upstream flow conditions.

[0130] A reservoir can refer to a container used to store fluids. In one possible implementation, the reservoir is equipped with a water level monitoring device to monitor the water level of the fluid in the reservoir. For example, if the volume of the fluid in the reservoir is less than two-thirds of the reservoir's capacity, fluid is obtained from a water source and the fluid in the reservoir is used to fill the reservoir to two-thirds of its capacity.

[0131] An electromagnetic flow meter can refer to an instrument used to measure the volumetric flow rate of a fluid. Electromagnetic flow meters measure the flow velocity and flow rate of a fluid through the principle of electromagnetic induction.

[0132] The electromagnetic flow meter is installed between the external water tank and the bidirectional pump, and can accurately measure the flow rate of the fluid in the external water tank.

[0133] It is understandable that by measuring the flow rate of the fluid in the external water tank in real time using an electromagnetic flow meter, the direction and speed of the bidirectional pump can be adjusted according to the flow rate of the fluid in the external water tank, so as to accurately simulate the stacking process of sedimentary strata.

[0134] To better describe the role of bidirectional pumps and other components in the stacking process simulation device Figure 7 A flowchart illustrating a method for determining the superposition process of sedimentary strata provided in this application. Figure 2 This method can be applied to overlay process simulation devices, and the executing entity of this method can be an overlay process simulation device, a server, a host, or other devices, such as... Figure 7 As shown, the method may include:

[0135] S701. Obtain the current water level change information of the outer water tank; wherein, the current water level change information represents the rate of change of the water level in the outer water tank.

[0136] Among them, water level change information can refer to the rate of change of the water level of the fluid in the external water tank.

[0137] In one alternative implementation, a water level sensor can be used to acquire the current water level of the external tank every second. The water level sensor may include, but is not limited to, float-type, pressure-type, or ultrasonic sensors. The water level sensor converts water level information into electrical signals, which can be recorded or analyzed by the entity executing this method.

[0138] Furthermore, the executing entity of this method can calculate the current water level change information of the outer water tank based on the current water level of the outer water tank obtained every second and the bottom area of ​​the outer water tank.

[0139] For example, the current water level change information of the outer water tank can be that the water surface is rising at a rate of 0.004 cm / s.

[0140] S702. If the current water level change information of the outer water tank is inconsistent with the preset water level change parameter threshold, the rotation speed of the bidirectional pump is adjusted until the water level change information of the outer water tank is consistent with the preset water level change parameter; wherein, the bidirectional pump is used to control the flow of fluid between the water storage tank and the outer water tank based on the rotation speed.

[0141] Among them, the preset water level change parameter threshold can refer to the water level change parameter threshold set in advance by the staff, which is used to evaluate whether the current water level change information of the external water tank meets the experimental requirements.

[0142] For example, the preset water level change parameter threshold can be set to the water level rising at a rate of 0.008 cm / s.

[0143] In one possible implementation, if the water level in the outer tank is rising, and the current water level change information in the outer tank is less than a preset water level change parameter threshold, the rotation speed of the bidirectional pump that pumps fluid from the storage tank to the outer tank can be increased to increase the fluid input, thereby accelerating the rate of rise of the water level in the outer tank until it reaches 0.008 cm / s.

[0144] If the current water level change in the outer tank is less than the preset water level change parameter threshold, the rotation speed of the bidirectional pump pumping fluid from the reservoir to the outer tank can be reduced to decrease the fluid input, thereby reducing the rate of water level rise in the outer tank until it reaches 0.008 cm / s. If the rotation speed of the bidirectional pump pumping fluid from the reservoir to the outer tank is 0, and it still cannot reduce the current water level change in the outer tank to 0.008 cm / s, then the direction of the bidirectional pump is adjusted to pump fluid from the outer tank to the reservoir until the current water level change in the outer tank is reduced to 0.008 cm / s.

[0145] In one alternative implementation, adjusting the rotational speed of the bidirectional pump may include:

[0146] The electromagnetic flow meter obtains the current flow parameters in the outer water tank; the flow parameters represent the flow velocity of the fluid in the outer water tank; if the current flow parameters are inconsistent with the preset flow parameters, the speed of the bidirectional pump is adjusted until the current flow parameters in the outer water tank are consistent with the preset flow parameters.

[0147] The preset flow parameters can refer to the flow parameters that are set in advance by the staff, which are used to evaluate whether the current flow parameters meet the experimental requirements.

[0148] In one possible implementation, the preset flow rate parameters of the outer water tank can be calculated using a preset water level change parameter threshold and the bottom area of ​​the outer water tank. Similarly, the current flow rate parameters in the outer water tank can be calculated using the current water level change information and the bottom area of ​​the outer water tank.

[0149] In one possible implementation, when the water level in the outer tank is rising and the direction of the bidirectional pump is to pump fluid from the reservoir to the outer tank, if the current flow rate parameter is less than the preset flow rate parameter, the rotation speed of the bidirectional pump to pump fluid from the reservoir to the outer tank is increased to increase the fluid input, thereby increasing the current flow rate parameter in the outer tank until the current flow rate parameter in the outer tank matches the preset flow rate parameter.

[0150] If the current flow rate parameter is less than the preset flow rate parameter, the rotation speed of the bidirectional pump that pumps fluid from the reservoir to the outer water tank is reduced to decrease the fluid input, thereby reducing the current flow rate parameter in the outer water tank until it matches the preset flow rate parameter.

[0151] The advantage of this setup is that by precisely controlling the flow rate in the outer tank, the water level in the outer tank can be controlled, thereby maintaining a stable water level in the outer tank to simulate specific sedimentation conditions.

[0152] The method for determining the superposition process of sedimentary strata provided in this application improves the accuracy of simulating the superposition process of sedimentary strata.

[0153] To better describe the front view in the method for determining the superposition process of sedimentary strata, Figure 8 A schematic diagram of the front view of the internal water tank provided in this application at a certain moment, as shown below. Figure 8 As shown, Figure 8 It includes the origin, the super-point, the super-point, and the point on the coastline.

[0154] The origin point can refer to the intersection of the bottom plate and the side bottom plate in the inner water tank. When viewed from the front, the origin point is at the lower right corner of the inner water tank.

[0155] The superposition point can refer to the point where the sediment layer covers the old sediment layer in a front view. It can be understood as the point where the new sediment layer covers the old sediment layer. In this embodiment, when looking at the inner water tank from a frontal view, the superposition point is at the upper right corner of the sediment layer.

[0156] The lower superposition point can refer to the point where the sediment layer covers downwards in a frontal view. It can be understood as the point where the new sediment layer is deposited below the old sediment layer. In this embodiment, when viewed from the frontal view of the inner water tank, the lower superposition point is at the lower left corner of the sediment layer.

[0157] The point on the coastline can be the point in the front view that corresponds to the boundary between the water surface of the fluid in the inner tank and the sediment.

[0158] To illustrate the front view obtained by the method for determining the superposition process of sedimentary strata in this application, the fluid in the inner flume can be understood as seawater or ocean, and the boundary between the water surface of the fluid in the inner flume and the sediment can be understood as coastline.

[0159] The origin point can refer to the intersection of the basin's landward basement and seaward basement; the top sedimentary layer terminates at the basin's landward basement in the direction of landward, which can be called the upper superposition point (or bedrock-alluvial transition point, ABT); the foreseary layer terminates at the basin's seaward basement in the direction of oceanward, which is called the lower superposition point; the foreseary layer and the top sedimentary layer intersect at the coastline.

[0160] Among them, the surface of the topsoil, the surface of the foresoil, the inland basement of the basin, and the ocean-facing basement of the basin can all be approximated as straight lines with constant slope, and the slope can be represented by the letters α, β, γ, and γ, respectively. This means that α represents the slope of the topsoil surface, β represents the slope of the foresoil surface, and γ represents the slope of the basin basement towards the inland side. It indicates the slope of the basin's base on the ocean side.

[0161] It is understandable that during the simulated depositional strata stacking process, as sediment accumulates in the natural environment, the overburden point, the coastline point, and the underburden point will change accordingly. In the actual depositional strata stacking process, the changes in the overburden point, coastline, and underburden point also mean that the scale and morphology of the strata will change with the depositional strata stacking process.

[0162] Figure 9 Schematic diagram of the front view of the internal water tank provided in this application at various times. Figure 1 ,like Figure 9 As shown, with Figure 8 Taking the schematic diagram of the front view of the inner flume at a certain moment as an example, the surface of the top sedimentary layer, the surface of the forese sedimentary layer, the basin basement on the inland side of the basin, and the basin basement on the ocean side of the basin can all be approximated as straight lines with constant slope. The slope can be represented by the letters α, β, γ, etc. This indicates that the front view of the inner water tank at various times can be obtained through... Figure 9 It means that, in Figure 9 In the above, β > γ, and the supersonic point, the point on the coastline, and the subsonic point change with time.

[0163] When β < γ, the overshoot point, the point on the coastline, and the undershoot point also change with time, such as Figure 10 As shown, Figure 10 Schematic diagram of the front view of the internal water tank provided in this application at various times. Figure 2 .

[0164] according to Figure 9 as well as Figure 10 The inflow rate of the water-sand mixture is used as... This indicates that the preset water level change parameter threshold is used... This indicates that the surface of the topsoil, the surface of the foresoil, the inland basement of the basin, and the oceanic basement of the basin can all be approximated as straight lines with constant slope, and the slope can be represented by the letters α, β, γ, ... This indicates that the inflow rate of the water-sand mixture is determined by a preset first rate (the rate at which fluid flows from the water tank into the funnel) and a preset second rate (the rate at which sediment flows from the sediment tank into the funnel), γ, It can be obtained by measuring the internal water tank, and α and β can be measured during the sediment deposition process.

[0165] Starting from the origin (0,0), an XZ reference coordinate system is established, where the horizontal axis X is positive in the seaward direction and the vertical axis Z is positive upward. The results of the front view of the inner water tank at each time point satisfy the following model:

[0166] ;

[0167] Where X represents the distance the point on the coastline moves to the left between the two front views, and Z represents the distance the point on the coastline moves upward.

[0168] in, It can refer to the spatial scale measurement in two-dimensional space under the background of sea level rise and fall, satisfying:

[0169] ;

[0170] in, The inflow rate of the water-sediment mixture. This is a preset threshold for water level change parameters.

[0171] , and The coefficients related to slope satisfy the following conditions:

[0172] ;

[0173] ;

[0174] .

[0175] Where α represents the slope of the topsoil surface, β represents the slope of the foresoil surface, and γ represents the slope of the basin basement on the inland side. It indicates the slope of the basin's base on the ocean side.

[0176] It is understandable that by flowing a water-sediment mixture into the inner flume, a frontal view of the inner flume at different times can be obtained. From this frontal view, the distribution of sediment and fluid within the inner flume can be understood, and thus the process of sediment formation into sedimentary strata can be understood, providing experimental evidence for geological research. This avoids the damage to experimental results caused by cutting three-dimensional sedimentary bodies into two-dimensional profiles, as is common in existing technologies. The method for determining the superposition process of sedimentary strata provided in this application improves the accuracy of simulating the superposition process of sedimentary strata.
