[0002] The foreland thrust belt lies at the basin-mountain transition zone between orogenic belts and basins. It is a thrust system formed by the large-scale thrusting of the orogenic belt toward the basin, and the subduction and collision of the basin-containing blocks beneath the orogenic belt. Located on the active flank of the foreland basin, this belt is a major reservoir of abundant oil and gas resources. Therefore, studying the geological structure of the foreland thrust belt can provide insights into petroleum exploration.

DETAILED DESCRIPTION

[0048] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

At the same time, by numerically simulating the deformation of natural geological structural phenomena, the changes in intrinsic stress and strain are obtained. Then, according to the correspondence between the physical simulation information and stress and strain, the numerical simulation process is adjusted, thereby combining the physical simulation information and the stress and strain analysis results, and the equilibrium profile information in the geological restoration process evolution information, the structural interpretation and simulation experiment profile results are verified and adjusted to obtain the target simulation evolution process information. In this way, the problem of high drilling costs and multiple solutions in the geological interpretation of seismic data in the formation and evolution of the structure is solved.

[0051] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

Determine the equilibrium profile of the foreland thrust belt, the physical simulation evolution results of the foreland thrust belt, and the numerical simulation evolution results of the target material, wherein the target material is the material required for the physical simulation of the salt layer or coal seam in the foreland thrust belt.

[0055] Among them, the balanced section can refer to the section obtained by restoring the structural deformation and displacement on the section through geometric criteria. The process of making the balanced section follows the conservation of volume, conservation of area, conservation of length, fault law, and principle of minimum energy. Among them, volume conservation can refer to the restoration based on the unchanged volume of the rock layer before and after deformation; area conservation can refer to the restoration based on the unchanged area of ​​the rock layer before and after deformation, which is used when there is no strain in the plane, no strike-slip component, and the section is perpendicular to the structural line; length conservation can refer to the restoration based on the unchanged length of the rock layer before and after deformation, which is used when the deformation is at low temperature and low pressure, there is no strike-slip component, and the section is perpendicular to the structural line; the fault law can refer to the shortening caused by the fault being consistent in the upper and lower rock layers, which is used when the deformation is at low temperature and low pressure, there is no strike-slip component, and the section is perpendicular to the structural line, and is suitable for local structural interpretation, such as faults and folds; the principle of minimum energy can refer to the fact that faults are prone to occur in areas where the minimum energy is required.

[0056] In the embodiment of the present application, determining the balanced profile of the foreland thrust belt may refer to selecting a profile that is nearly consistent with the direction of tectonic movement under the basic principle of making a balanced profile, determining the slip surface and fault surface according to the conditions of the rock formation, and compacting or correcting the rock formation. On this basis, a nail line is set and a balanced model is selected according to the structural style, thereby obtaining a balanced profile to restore the structure.

[0057] Physical simulation can refer to analyzing and interpreting acquired regional geological profiles and remote sensing data in combination with structural feature analysis, conducting basic profile and plane experimental tests, screening suitable materials to simulate different strata, screening parameters that meet the requirements, setting boundary geometry conditions, and designing corresponding physical simulation models. In the embodiments of the present application, physical simulation can refer to simulating strata using different materials, applying loads to the materials, observing and recording the process of model structural extrusion deformation, and summarizing the tectonic evolution mechanism by comparing with the actual geological model to obtain physical simulation evolution results.

[0058] The physical simulation evolution results can refer to the full recording of the physical simulation using video equipment and analytical techniques to obtain the fault development process, and quantitative analysis of the experimental process to obtain mechanical analysis data such as strain and deformation during the fault development process, and the analysis and interpretation of the resulting structural deformation evolution process. In some embodiments, the application of loads to the material can be simulated by setting the operating speed and distance of the electric cylinder device to simulate the application of forces such as compression, stretching, strike-slip, and arching. The analytical technology can refer to the use of particle imaging velocimetry (PIV) technology to digitize the images and obtain relevant parameters such as linear strain, surface strain, shear strain, and eddy strain during the model change process, thereby obtaining the finite strain state during the model deformation evolution process.

[0059] Numerical simulation can refer to the image interpretation of remote sensing data acquired based on the actual geological model and combined with regional geological profile analysis, the establishment of a solid model, and on this basis, the determination of material properties and meshing, the application of loads and boundary constraints, the writing of corresponding model code, the execution of solution operations, the interpretation of the code running results, the generation of relevant stress maps, the comparison with the actual profile, the repeated modification of boundary conditions, the acquisition of relatively reasonable results, and the completion of the calculation output. In the embodiment of the present application, numerical simulation can refer to the rock mechanical parameters of the foreland basin, and the microscopic parameters measured through rock strength experiments, including tensile tests, compression tests, triaxial compression tests, shear tests, etc., including Young's modulus, Poisson's ratio of material, tensile strength, polymerization strength, bulk modulus, cohesion, internal friction angle, etc., which can be used as the model microscopic input parameters of the numerical simulation experiment, and the boundary conditions of the experimental model are set according to the principle of geometric similarity, and the deformation rate of the experimental model is set according to the principle of dynamic similarity. Then, through the numerical simulation software, the corresponding code is written, and the walls in the left, right and bottom directions are used as boundaries to replace the electric cylinder and push plate in the physical simulation. The corresponding movement speed of a certain wall is assigned to replace the electric cylinder in the physical simulation to complete the simulation of the tectonic movement force. At the same time, the code can also simulate complex models such as pre-existing faults, pre-existing basements, pre-existing paleo-uplifts, and syntectonic sediments. Finally, the displacement, stress, strain and other information are monitored in real time during the numerical simulation to obtain data information of the deformation evolution stage. In some embodiments, the numerical simulation software may refer to software such as UDEC (Universal Distinct Element Code) software and PFC (Particle Flow Code) software that can simulate the structural evolution process.

[0060] In this embodiment, numerical simulation can be performed by writing code using discrete element numerical simulation software ZDEM to simulate the kinematic and mechanical behaviors of the particles, explain the intrinsic mechanism of material interaction during deformation from a microscopic perspective, and obtain numerical simulation evolution results.

[0061] The evolution results of numerical simulation can refer to the real-time monitoring and recording of the numerical simulation process, obtaining multiple quantitative data such as structural morphology, volume strain, average stress, etc., and calculating the stress and strain field of the model based on the data information in the deformation evolution stage, or the dynamic evolution results obtained by performing single-factor quantitative analysis on the model.

[0062] In the embodiment of the present application, before determining the equilibrium profile of the foreland thrust belt, the physical simulation evolution results of the foreland thrust belt, and the numerical simulation evolution results of the target material, the method may further include:

[0063] Determine the material information required for simulating salt layers or coal layers when performing physical simulation of foreland thrust belts, as well as the material parameter information of the materials in the material information;

[0064] Based on the material information and the material parameter information of the material in the material information, the numerical simulation evolution results of the target material are obtained. When the target material is the material required for physical simulation of the salt layer in the foreland thrust belt, the target material includes silica gel for simulating the salt layer. When the target material is the material required for physical simulation of the coal seam in the foreland thrust belt, the target material includes glass beads for simulating the coal seam and quartz sand for simulating the brittle formation.

[0065] Among them, material information can refer to the material property characteristics similar to those determined based on the rheological properties of natural rocks, and can be divided into plastic strata and brittle strata according to the different mechanical properties of strata. Among them, the rheological properties of natural rocks can be manifested as brittle deformation, ductile deformation, and brittle-ductile combination. Its performance properties depend on the internal friction coefficient and cohesion. Therefore, the characteristic parameters of each rock layer in nature are considered, including density, elastic modulus, bulk modulus, shear modulus, Poisson's ratio, cohesion, friction angle, and viscosity. The details are shown in Table 1:

[0066] Table 1

[0067]

[0068] Therefore, through the characteristic parameters of quartz sand and glass beads, as shown in Table 2, it is determined that different glass beads are selected to simulate coal seams with different strengths, and quartz sand is used to simulate brittle formations. At the same time, when the strain rate is less than 3×10 -3 S -1 When the silica gel can reflect the slow strain of Newtonian viscous fluid, its 10 4 The viscosity of Pa·s can simulate the deformation of salt rock layer, so silica gel is selected to simulate salt layer.

[0069] Table 2

[0070]

[0071] The material information required to simulate the salt layer or the coal layer when performing physical simulation of the foreland thrust belt can refer to that when the foreland thrust belt contains coal seams, the material information includes glass beads and quartz sand of different purposes; when the foreland thrust belt contains salt layers, the material information includes silica gel; when the foreland thrust belt contains coal seams and salt layers, the material information is glass beads of different purposes, quartz sand, and silica gel.

[0072] The material parameter information may refer to the microscopic input parameters of the material determined according to the characteristic parameters of the rock formation as shown in Table 1, including Poisson's ratio, Young's modulus, shear modulus, tensile strength, polymer strength, friction coefficient, etc.

[0073] According to the material information and the material parameter information of the material in the material information, the numerical simulation evolution results of the target material can be obtained by comparing the actual material parameters and determining the microscopic parameters of the model. The contact between particles adopts a simplified linear elastic contact model, and the kinematic and mechanical behaviors of the particles under Newton's law are simulated and calculated. The stress-strain curve obtained by the numerical simulation of the biaxial experiment is used to calculate the friction coefficient and shear modulus between different particles, the cohesion, internal friction angle and other macroscopic parameters corresponding to the sample, the boundary conditions of the experimental model are set according to the principle of geometric similarity, and the deformation rate of the experimental model is set according to the principle of dynamic similarity, and then the numerical simulation evolution results are obtained through numerical simulation software.

[0074] S102. Obtain target numerical simulation evolution results according to the physical simulation evolution results and the numerical simulation evolution results.

[0075] The target numerical simulation evolution result may refer to the structural evolution process determined by numerical simulation on the premise that the physical simulation evolution result and the numerical simulation evolution result form a comparative relationship.

[0076] According to the physical simulation evolution results and the numerical simulation evolution results, obtaining the target numerical simulation evolution results can mean that in the process of performing physical simulation and numerical simulation, it is necessary to perform geometric similarity comparison correction between the equilibrium profile and the physical simulation evolution results to ensure that the simulation results of the physical simulation experiment are reasonable, and then compare the physical simulation results and the numerical simulation results to ensure that the simulation evolution results of the two are consistent. The obtained physical simulation evolution results and the numerical simulation evolution results need to be compared with each other. If the two do not satisfy the comparison relationship, it is necessary to adjust the microscopic parameters in the numerical simulation experiment until the two satisfy the comparison relationship. The obtained numerical simulation evolution results are the target numerical simulation evolution results. In an embodiment of the present application, numerical simulation can monitor the position and stress state of particles in real time. The parameters of material stress and strain in the physical simulation process can be obtained by PIV technology. Therefore, by comparing the stress conditions of particles in the numerical simulation process and the stress and strain data of the model material in the physical simulation process, the comparison relationship between the physical simulation evolution results and the numerical simulation evolution results can be determined. In some embodiments, the correspondence between the physical simulation evolution results and the numerical simulation evolution results can also be determined by the geometric similarity of the model, that is, by comparing the structure of the model during the physical simulation process and the structure of the formation during the numerical simulation process, the similarity between the physical simulation evolution results and the numerical simulation evolution results can be determined.

[0077] In the embodiment of the present application, the method of obtaining the target numerical simulation evolution result according to the physical simulation evolution result and the numerical simulation evolution result may include:

[0078] Comparing the stress-strain analysis data in the numerical simulation evolution results with the mechanical analysis data in the physical simulation evolution results, a comparison result is obtained;

[0079] If the comparison result meets the preset comparison requirements, the numerical simulation evolution result is determined to be the target numerical simulation evolution result.

[0080] Among them, the control processing can refer to verifying the geometric similarity and kinematic similarity between the physical simulation evolution results and the numerical simulation evolution results. In an embodiment of the present application, the stress and strain analysis data in the numerical simulation evolution results and the mechanical analysis data in the physical simulation evolution results are subjected to control processing. Obtaining the control result can refer to obtaining the mechanical analysis data in the physical simulation process by using PIV technology in physical simulation, such as stress and strain parameters, thereby conducting a kinematic study on the physical simulation experiment, and using this as evidence to compare the stress and strain analysis data obtained in the numerical simulation experiment to obtain the control result.

[0081] In some embodiments, the particle production and deposition process can be observed by using the discrete element method in numerical simulations to reflect the structural changes of the formation, thereby conducting geometric studies on the numerical simulation experiments and obtaining geometric similarities between the physical simulation and the numerical simulation.

[0082] The preset control requirements may refer to the basic similarity of parameters such as stress and strain in the physical simulation evolution results and the numerical simulation evolution results, and the basic similarity of structural morphology. Due to the influence of errors in physical simulation experiments and the limitations of computer programs in numerical simulation experiments, it is impossible to guarantee that the results of the two are completely consistent. The control requirements are determined by researchers based on their professional knowledge.

[0083] In the embodiment of the present application, after performing comparison processing on the stress-strain analysis data in the numerical simulation evolution results and the mechanical analysis data in the physical simulation evolution results, the method for obtaining the comparison results may further include:

[0084] If the control result does not meet the preset control requirements, adjusting the material parameter information of the target material, the material parameter information of the target material including at least one parameter of Poisson's ratio, Young's modulus, shear modulus, tensile strength, polymerization strength, and friction coefficient;

[0085] According to the material parameter information of the adjusted target material, the adjusted numerical simulation evolution result is obtained;

[0086] The adjusted numerical simulation evolution result is used as the numerical simulation evolution result, and the steps of comparing the stress and strain analysis data in the numerical simulation evolution result and the mechanical analysis data in the physical simulation evolution result are repeatedly performed to obtain the comparison result, until the comparison result between the adjusted numerical simulation evolution result and the physical simulation evolution result meets the preset comparison requirements, and the adjusted numerical simulation evolution result is determined to be the target numerical simulation evolution result.

[0087] Among them, the fact that the comparison result does not meet the preset comparison requirements may mean that since the numerical simulation is performed through a computer program and relies on the existing structural deformation formula, there is a certain degree of randomness, and the authenticity of the numerical simulation results cannot be confirmed. Therefore, the numerical simulation evolution results are compared with the physical simulation evolution results to eliminate possible erroneous values. For example, the fault angle is obtained through physical simulation, but the fault obtained through numerical simulation is not within the fault angle range obtained by physical simulation, then the numerical simulation needs to be corrected. In the embodiment of the present application, according to the material parameter information of the adjusted target material, obtaining the adjusted numerical simulation evolution result can refer to adjusting the microscopic parameters and performing simulation calculations again using the computer program until the preset comparison requirements are met with the physical simulation evolution results.

[0088] S103. Obtain target evolution process information based on the equilibrium profile of the foreland thrust belt, the physical simulation evolution results, and the target numerical simulation evolution results.

[0089] Among them, the target evolution process information can refer to the combination of morphological changes in the physical simulation evolution results and stress-strain analysis in the target numerical simulation evolution results, and comparison with the equilibrium profile of the foreland thrust belt. If the geometric similarity and kinematic similarity between the profiles meet the requirements, then the dynamic evolution process of stratum deformation during the tectonic evolution of the foreland thrust belt represented by the obtained physical simulation evolution results and the target numerical simulation evolution results is the target evolution process information.

[0090] According to the equilibrium profile of the foreland thrust belt, the physical simulation evolution results and the target numerical simulation evolution results, the target evolution process information can be obtained by comparing and correcting the equilibrium profile with the physical simulation evolution results in a geometric similarity manner to ensure that the simulation results of the physical simulation experiment are reasonable. If the similarity between the two is weak, the physical simulation experiment is reconstructed and compared with the equilibrium profile until the similarity between the two is high. The numerical simulation experiment is then reconstructed for verification, and the physical simulation results are compared with the numerical simulation results to ensure that the simulation results of the two are consistent. Otherwise, the numerical simulation experiment is redesigned until the physical simulation experiment and the numerical simulation experiment are compared with each other. Finally, the simulation results of the physical simulation experiment and the numerical simulation experiment are compared. The evolution results are compared with the equilibrium profile, and the unreasonable parts in the restoration of the equilibrium profile are corrected. The above experimental steps are repeated until the three are compared. The evolution process verified by the physical simulation experiment and the numerical simulation experiment is determined to be the target evolution process. The physical simulation process is recorded with a camera to obtain equal-interval photos, and the strain and deformation effects in the pictures are quantitatively analyzed through PIV calculation processing. At the same time, by combining the target numerical simulation evolution results, that is, multiple quantitative data such as structural morphology, volume strain, average stress, etc. in the entire evolution process, the target evolution process information is obtained. Through the target evolution process information, the influence of the main controlling factors on the structural evolution can be confirmed.

[0091] In an embodiment of the present application, redesigning the physical simulation experiment may refer to changing the main controlling factors in the physical simulation experiment, including the thickness of the plastic layer, the co-deposition thickness, the extrusion strength, and the strength of the slip layer. Redesigning the numerical simulation experiment may refer to changing the microscopic parameters in the numerical simulation experiment, including Poisson's ratio, Young's modulus, shear modulus, tensile strength, polymerization strength, friction coefficient, etc.

[0092] In some embodiments, obtaining target evolution process information based on the equilibrium profile of the foreland thrust belt, physical simulation evolution results, and target numerical simulation evolution results can also refer to correcting the initial model established based on seismic data and drilling data, and re-conducting equilibrium profile restoration and geological evolution process on this basis, repeating the above experimental steps again to obtain the geological evolution process.

[0093] In the embodiment of the present application, the method for obtaining target evolution process information based on the equilibrium profile of the foreland thrust belt, the physical simulation evolution results, and the target numerical simulation evolution results may include:

[0094] Comparing the equilibrium profile of the foreland thrust belt with the physical simulation evolution results and the target numerical simulation evolution results respectively to obtain a first comparison result and a second comparison result, wherein the comparison processing includes geometric similarity comparison and kinematic similarity comparison;

[0095] If both the first comparison result and the second comparison result meet the preset comparison requirements, the target evolution process information is obtained according to the physical simulation evolution result and the target numerical simulation evolution result.

[0096] Among them, geometric similarity comparison can refer to comparing the simulated profile results and the equilibrium profile restoration results in the physical simulation evolution results and the target numerical simulation evolution results to verify the geometric similarity of the profile distribution of the fault system, the structural morphology of the coal seam and its spatial position, the structural morphology of the rock layer and its spatial position, and the overall structural morphology of the profile.

[0097] Kinematic similarity comparison can refer to comparing the simulated profile results and the equilibrium profile restoration results in the physical simulation evolution results and the target numerical simulation evolution results to verify the similarity of changes in kinematic characteristics such as fault active layers and profile shortening rates.

[0098] The preset comparison requirements can refer to the profile comparison similarity preset according to the experimental process. Since both physical simulation and numerical simulation have conditional limitations, it is impossible to ensure that the comparison results are completely consistent. Researchers need to determine the similarity requirements based on professional knowledge.

[0099] If both the first comparison result and the second comparison result meet the preset comparison requirements, then the target evolution process information is obtained according to the physical simulation evolution result and the target numerical simulation evolution result. If the profile comparison similarity is strong, then by performing morphological recording and strain calculation on the physical simulation evolution process, and combining the stress-strain analysis data obtained from the numerical simulation evolution process, the dynamic evolution process of stratum deformation in the tectonic evolution of the coal-bearing and salt-bearing foreland basin is analyzed to obtain the target evolution process information.

[0100] In the embodiment of the present application, after comparing the equilibrium profile of the foreland thrust belt with the physical simulation evolution result and the target numerical simulation evolution result to obtain the first comparison result and the second comparison result, the comparison processing includes geometric similarity comparison and kinematic similarity comparison, and the method may further include:

[0101] If the first comparison result and the second comparison result do not meet the preset comparison requirements, the first comparison result and the second comparison result are displayed;

[0102] Obtaining an updated equilibrium profile re-entered by the user based on the first comparison result and the second comparison result;

[0103] According to the updated equilibrium profile, the updated physical simulation evolution results and the updated numerical simulation evolution results, the updated target evolution process information is obtained.

[0104] Among them, the failure of the first comparison result and the second comparison result to meet the preset comparison requirements may mean that the profile comparison similarity is weak, and there is a large gap between the simulation result and the equilibrium profile. In this case, the seismic profile interpretation is changed, and the equilibrium profile restoration is re-performed to obtain an updated equilibrium profile, and the above-mentioned physical simulation process is repeatedly constructed until the first comparison result of the equilibrium profile and the physical simulation evolution result meets the similarity requirement, and then the numerical simulation process is performed. When the result of the numerical simulation process is consistent with the physical simulation result, it is determined that the second comparison result of the equilibrium profile and the numerical simulation evolution result meets the similarity requirement, and an updated physical simulation evolution result and an updated numerical simulation evolution result are obtained. Therefore, based on the updated physical simulation evolution result and the updated numerical simulation evolution result, the tectonic evolution process is determined, and the updated target evolution process information is obtained.

[0105] In the embodiment of the present application, after obtaining target evolution process information based on the equilibrium profile of the foreland thrust belt, the physical simulation evolution results, and the target numerical simulation evolution results, the method may further include:

[0106] Generate evolution process display information based on target evolution process information, including structure interpretation information, data processing information, and evolution process visualization information;

[0107] Display the evolution process to display information.

[0108] Among them, based on the target evolution process information, generating evolution process display information can refer to making equally spaced photos recorded during the physical simulation process into a video to demonstrate the fault development process, and summarizing the mechanical analysis data obtained by PIV calculation processing into an animation to display and analyze the model strain and deformation mechanism, and making multiple quantitative data obtained during the numerical simulation process into video animations, and displaying these videos and animations to analyze the dynamic evolution process of stratum deformation in the tectonic evolution of coal-bearing and salt-bearing foreland basins, analyzing the influence mechanism of coal seams and salt seams on tectonic evolution during the evolution of foreland basins, and exploring the control factors and formation mechanisms of faults in the region.

[0109] The foreland thrust belt structural simulation method provided in the embodiment of the present application can be achieved by restoring the equilibrium profile of the foreland thrust belt and conducting physical simulation experiments to verify the structural evolution process, ensuring that the physical simulation evolution results are consistent with the equilibrium profile, and then conducting numerical simulation experiments to carry out stress-strain analysis until the numerical simulation evolution results are compared with the physical simulation evolution results to obtain the target numerical simulation evolution results, and then comparing the morphological changes of the physical simulation evolution results and the stress-strain analysis of the target numerical simulation evolution results with the equilibrium profile, and re-performing the equilibrium profile restoration based on the comparison results until the comparison results are consistent, and then interpreting the model to obtain the target evolution process information, thereby studying the characteristics of the structural deformation of the coal-containing and salt-containing foreland thrust belt during the geological evolution process, and proving the rationality of the model by combining physical simulation and numerical simulation, thereby achieving the effect of accurately demonstrating the formation and evolution process of the geological structure.

[0110] Figure 2 This is a flow chart of another foreland thrust belt structure simulation method provided in the embodiment of the present application. Figure 2 As shown, with the electronic device as the execution subject, the method of this embodiment may include the following steps:

[0111] S201. Conduct structural interpretation of seismic data, obtain seismic profiles, and establish an initial model.

[0112] Among them, seismic data can refer to the judgment of underground structure through seismic waves. When seismic waves propagate underground and encounter rocks with different density, hardness, and material composition, they will cause reflection, diffraction and other phenomena, thereby obtaining data.

[0113] Structural interpretation of seismic data refers to determining the morphology and spatial position of geological structures based on seismic data, inferring the lithology, thickness and inter-layer contact relationship of the strata, determining the possibility of oil and gas in the strata, providing accurate well locations for drilling, etc., which is affected by the ability and imagination of the interpreters. Therefore, seismic data has multiple solutions. At the same time, since seismic data is an indirect reflection of underground geological characteristics, the same geological phenomenon may have different seismic responses, different geological phenomena may have the same seismic response, and seismic data may contain noise, false images, or even fail to form images, so it itself has multiple solutions.

[0114] In the embodiments of the present application, performing structural interpretation on seismic data, obtaining seismic profiles, and establishing an initial model may refer to obtaining seismic profiles based on the acquired seismic data, thereby determining the geological structural morphology and spatial position, inferring the lithology, thickness, and interlayer contact relationships of the strata, and establishing an initial model. Structural interpretation may refer to inferring the geological horizons corresponding to each reflective layer from drilling geology and various logging data obtained from wells in the study area, combined with the characteristics of each reflective layer in the seismic data, and analyzing various geological phenomena reflected in the seismic data, such as structures, faults, unconformities, stratigraphic pinch-outs, and various special geological bodies, to complete the structural interpretation of various data in two or three dimensions.

[0115] S202. Select experimental materials suitable for simulating the strata in the physical simulation and appropriate parameters in the numerical simulation.

[0116] Among them, the properties of the experimental materials selected for simulating strata in physical simulation need to be related to the characteristics of natural rocks. Since the key factors affecting material behavior include friction characteristics, internal friction angle, cohesion, and material density, and non-critical factors include force standards, particle distribution, and particle shape, the key factors are the main considerations when selecting materials. In the embodiment of the present application, selecting experimental materials suitable for simulating strata in physical simulation can refer to selecting glass beads of different purposes to simulate coal seams of different strengths, quartz sand to simulate brittle strata, and silica gel to simulate salt layers.

[0117] In the numerical simulation, since the microscopic parameters control the macroscopic response of the granular material, round particles are used to simulate the deformation behavior of quartz sand and glass beads, and the contact between particles adopts a simplified linear elastic contact model. Through rock strength experiments, including tensile tests, compression tests, triaxial compression tests, shear tests, etc., the measured parameters such as Young's modulus, Poisson's ratio, tensile strength, polymerization strength, bulk modulus, cohesion, internal friction angle, etc. are the appropriate parameters determined in the numerical simulation.

[0118] S203. Carry out equilibrium profile restoration to restore the geological evolution process.

[0119] The balanced profile restoration can be carried out through the following steps: selecting a profile perpendicular to the strike of the regional structure and approximately consistent with the direction of the tectonic movement; collecting and analyzing the surface outcrop and drilling data of the strata and structure of the research area, accurately projecting and marking the stratum boundary and occurrence seen on the surface, the fault position and occurrence and the underground conditions seen in the well on the profile line, and determining the decollement and fault plane; in the balancing process, the strata are corrected for compaction or decompaction according to different balancing methods; the nail line is confirmed, and when the nail line is set, strong folds or sections with obvious secondary interference factors are avoided as much as possible; the corresponding balancing model is selected according to the tectonic stress environment of the research area and the tectonic style reflected by the profile; the balancing is repeatedly adjusted and tested, the regional nail line is fixed, and each stratum is flattened and moved back to the position and horizontal state before deformation. The initial diagram after the model recovery is the initial diagram of S204 and S205.

[0120] S204, physical simulation experiment is carried out to verify the tectonic evolution process.

[0121] The physical simulation experiment is completed through laboratory equipment, and parameters such as the material of the model, the thickness of each stratum, and the boundary conditions are considered. The experimental material determined in S202 is used, quartz sand is used to simulate brittle strata, glass beads are used to simulate coal-bearing plastic layers, silica gel is used to simulate salt-bearing plastic layers, and materials such as siltstone and water-containing quartz sand can simulate paleo-uplifts. Different color quartz sand can be used as a marker layer or to distinguish different layers. In this way, a simulation model is constructed. According to the tectonic evolution process of the research area, corresponding tectonic forces are applied, and the whole process of the physical simulation experiment is recorded by using a camera and particle imaging velocimetry technology. Different materials are used to simulate the tectonic evolution process of the target period. The image is data-based, the motion trajectory of a particle in the model is obtained, and the strain mechanical parameters of the model are further obtained. In the embodiments of the present application, after the physical simulation experiment is carried out to verify the tectonic evolution process, the equidistant slice photos can also be three-dimensionally reconstructed. The reconstructed model can carry out tangent, oblique cutting and material segmentation at any position of the model. At the same time, the data obtained by three-dimensional reconstruction are summarized and analyzed, the tectonic deformation effect is quantified, and the deep structure of the model is directly displayed.

[0122] S205, numerical simulation experiment is carried out to carry out stress and strain analysis.

[0123] The numerical simulation experiment simulates the interaction relationship of substances through the discrete element method, uses numerical simulation software and corresponding codes to simulate the tectonic movement force and evolution process, obtains real-time stress, strain, velocity, energy and other information, and calculates the stress and strain field of the model according to the data information of the deformation evolution stage.

[0124] S206. Combine the morphological changes of the physical simulation and the stress-strain analysis of the numerical simulation and compare them with the equilibrium section. If there is a large gap between the simulation results and the equilibrium section, redesign the model and repeat S203, S204, S205, and S206 until the simulated section is highly similar to the equilibrium section.

[0125] Combining the morphological changes of physical simulations with the stress-strain analysis of numerical simulations, comparison with the equilibrium profile can refer to using the equilibrium profile as a reference, physical simulation experiments as the primary verification method, and numerical simulation as an auxiliary verification method. Model simulation is carried out with the main influencing factors as variables, and the simulation results are compared with the equilibrium profile recovery results to verify the geometric and kinematic similarity between the profiles. If the profile comparison similarity is weak, it is necessary to change the main controlling factors and redesign the physical and numerical simulation experiments until the simulated profile is highly similar to the equilibrium profile. At the same time, the physical simulation profile and the numerical simulation profile must also correspond to each other. Among them, the main controlling factors include the thickness of the plastic layer, the syndepositional thickness, the extrusion strength, the strength of the slip layer, etc.

[0126] S207. Interpret and analyze the simulation model, and create video animation to restore and display the evolution process.

[0127] Among them, the simulation model can refer to the model obtained through the above steps that has a small similarity gap with the equilibrium section, interpreting and analyzing the simulated model, and making video animation to restore and display the evolution process. It can refer to analyzing the images obtained in the physical simulation experiment and their corresponding strain and deformation effects, and combining the stress, strain and other data obtained in the numerical simulation experiment to restore and display the evolution process of the target area.

[0128] Another method for simulating foreland thrust belt structures provided in an embodiment of the present application can obtain a balanced profile by interpreting seismic data, and combine physical simulation experiments with numerical simulation experiments, which includes both model morphological changes and model stress-strain analysis, thereby verifying the rationality of the model and reproducing the formation and evolution process of the coal- and salt-bearing foreland thrust belt structure.

[0132] Quartz sand is used to simulate brittle strata, glass beads to simulate coal-bearing plastic layers, and silica gel to simulate salt-bearing plastic layers. Materials such as mesh soil and hydrated quartz sand can simulate paleo-uplifts. Different colored quartz sands can be used as marker layers or to distinguish different strata. Based on the tectonic evolution of the target study area, corresponding tectonic forces are applied to the model. Forces such as compression, stretching, strike-slip, and arching can be applied using electric cylinders. Cameras and particle imaging velocimetry are used to record the entire process, resulting in a physical simulation of the geological evolution process.
