[0002] The existence of strike-slip faults is of great significance for oil and gas exploration. If the strike-slip faults cut through the basement layer (thick-skinned structure), they may cause serious damage to existing deep oil and gas traps. If the strike-slip faults only develop in the overlying layer or inside the salt layer (thin-skinned structure), they may have no impact on the oil and gas traps. Therefore, how to identify strike-slip faults is a technical problem that needs to be solved urgently.

[0003] At present, the main scheme is to study the deformation of strike-slip fault geological structures based on structural physics simulation experiments.

[0026] Embodiment 1

[0027] Figure 1 A flowchart of a method for identifying a strike-slip fault is provided for the first embodiment of the present application. The embodiment of the present application can be applied to the case of identifying a strike-slip fault. The method can be executed by a strike-slip fault identification device. The strike-slip fault identification device can be implemented in the form of hardware and / or software. The strike-slip fault identification device can be configured in an electronic device with data processing capabilities. Figure 1 As shown, the method includes:

[0028] S110, constructing a simulation model based on the cross-sectional image information of the physical geological model; the physical geological model reflects the geological information of the target area.

[0029] Among them, the physical geological model can be constructed according to the geological information of the target area. The construction process of the physical geological model can reflect the geological evolution process. Therefore, the physical geological model can reflect the stratigraphic distribution information of the target area. The profile image information can be the image information of each profile of the physical geological model. Multiple profile image information can more comprehensively reflect the internal information of the physical geological model, that is, the geological information of the target area. The simulation model is a three-dimensional virtual model corresponding to the physical geological model. Since the physical geological model reflects the geological information of the target area, the simulation model also reflects the geological information of the target area.

[0030] Specifically, since the basement layer of the target area is usually a certain distance away from the surface, the relevant information of the basement layer is not easy to explore. Therefore, a physical simulation experiment can be used to construct a physical geological model that can reflect the geological information of the target area. Then, based on the cross-sectional image information of the physical geological model, a simulation model is constructed through three-dimensional reconstruction software, thereby obtaining a simulation model that can reflect the geological information of the target area.

[0031] In the embodiment of the present application, the physical geological model is constructed based on relevant geological information of the target area, such as stratum thickness, stratum evolution information, etc. Therefore, the basement layer part of the physical geological model corresponding to the target area can still reflect the geological evolution information even if it is located inside the model, that is, the strike-slip structure inside the physical geological model can reflect the strike-slip structure of the target area.

[0032] In the embodiment of the present application, the simulation model is a computer three-dimensional virtual model. The simulation model has the advantages of a lot of observable information and reusability, which are specifically reflected in the following aspects: the existing physical geological model cannot be restored after slicing, and the slicing angle is single. The embodiment of the present application avoids the above-mentioned shortcomings of the physical geological model by constructing a simulation model, and has the characteristics of being reusable (the simulation model can be restored after slicing) and containing more information (for example, the internal information of the simulation model can be obtained from different angles).

[0033] In the embodiment of the present application, optionally, before constructing the simulation model based on the cross-sectional image information of the physical geological model, the method further includes:

[0034] Performing electronic computer tomography scanning on the physical geological model to obtain cross-sectional image information of the physical geological model; and / or cutting the physical geological model to obtain a cut cross section of the physical geological model; acquiring image information of the cut cross section by a photographing device to obtain cross-sectional image information of the physical geological model.

[0035] The electronic computer tomography scan refers to CT scan. The photographing device may be a digital camera, a high-definition camera, or the like.

[0036] Specifically, in one feasible solution, the physical geological model can be subjected to electronic computed tomography scanning to obtain cross-sectional image information of the physical geological model, and this method will not damage the physical geological model. In another feasible solution, the cut cross section of the physical geological model can be photographed by a photographing device to obtain cross-sectional image information of the physical geological model. It should be noted that any of the above methods can be selected to obtain cross-sectional image information of the physical geological model according to actual conditions, and the specific method for obtaining cross-sectional image information of the physical geological model is not limited in the embodiment of the present application.

[0037] It should be noted that after obtaining the cross-sectional image information, some parameter adjustments may be required, such as adjusting the size of the cross-sectional images to be consistent, leveling the cross-sectional images, etc., and then constructing a simulation model based on the cross-sectional image information through computer software.

[0038] S120, performing strike-slip fault identification on the simulation model, and determining whether a strike-slip fault exists in the basement layer of the target area according to the identification result.

[0039] Among them, strike-slip fault identification refers to identifying whether there is a strike-slip fault in the basement layer of the simulation model. The basement layer of the simulation model can be identified by image processing to obtain an identification result.

[0040] Specifically, when constructing a physical geological model, the basement layer of the target area can be simulated using materials of the same material but different colors. For example, the color of the material is different at different heights. This arrangement ensures that when a strike-slip fault occurs in the basement layer of the physical geological model, the color distribution of the basement layer is no longer the same at the same height. Thus, image recognition can be used to determine whether a strike-slip fault occurs in the basement layer of the simulation model, that is, whether a strike-slip fault occurs in the basement layer of the target area.

[0041] Specifically, since the simulation model is a three-dimensional model, the basement layer corresponding to the simulation model can be pre-positioned. If image recognition is performed on different sections of the simulation model, and the result is that the colors of a certain height interval are the same, it can be determined that there is no strike-slip fault in the basement layer of the target area; otherwise, there is a strike-slip fault. It should be noted that image recognition can be performed from various angles of the three-dimensional model to obtain a recognition result.

[0042] The technical solution of the embodiment of the present application includes: constructing a simulation model based on the cross-sectional image information of the physical geological model; the physical geological model reflects the geological information of the target area; performing strike-slip fault identification on the simulation model, and determining whether there is a strike-slip fault in the basement layer of the target area according to the identification result. The technical solution identifies the strike-slip fault on the simulation model, and the identification process is a three-dimensional analysis, so that the identification result is more accurate, and the simulation model is a computer virtual model, which is reusable, so that the identification of the strike-slip fault can be performed multiple times.

[0043] In an embodiment of the present application, optionally, the method further includes: determining the layer thickness of the physical geological model according to the stratum thickness of the target area; determining the deformation amount of the physical geological model according to the geological shortening amount and / or geological tension amount of the target area; determining the deformation rate of constructing the physical geological model according to the geological shortening rate and / or geological tension rate of the target area; and constructing the physical geological model according to the layer thickness, deformation amount and deformation rate.

[0044] Among them, information such as the stratum thickness information of the target area, the geological shortening amount and / or geological tension amount of the target area, the geological shortening rate and / or geological tension rate of the target area reflects the geological evolution process of the target area. Based on the above information, a physical geological model reflecting the geological information of the target area can be established.

[0045] Exemplarily, geological evolution can be divided into plastic deformation and brittle deformation. Silica gel can be used to simulate plastic rock layers. For example, salt rock layers are plastic deformation strata. Dry loose quartz sand can be used to simulate brittle rock layers, such as subsalt basement layers and salt overburden layers. The physical geological model in the embodiment of the present application can be quartz sand-silica gel-quartz sand from top to bottom, simulating the salt overburden layer, salt rock and subsalt basement layer respectively. It should be noted that, as mentioned above, the quartz sand simulating the basement layer has different colors at different heights to reflect whether a strike-slip fault has occurred in the stratum in subsequent steps.

[0046] Exemplarily, based on the principle of similarity between the physical geological model and the natural prototype in geometry, kinematics and dynamics, according to the surface geological field outcrop data of the target area, exploration seismic profile drilling data, lithology distribution map and other data, combined with basic geological theory, the relevant parameters of the target area (stratum distribution, compression displacement, structural evolution time, compression rate, etc. of the target area) are determined; then, based on the principle of similarity, according to the stratum thickness of the target area, the layer thickness of the physical geological model is determined; according to the geological shortening and / or tensioning amount of the target area, the deformation amount of the physical geological model is determined; according to the geological shortening and / or tensioning rate of the target area, the deformation rate of the physical geological model is determined; and then, the physical geological model is constructed according to the layer thickness, deformation amount and deformation rate.

[0047] Embodiment 2

[0048] Figure 2 This is a flow chart of a strike-slip fault identification method provided in Example 2 of the present application. This embodiment of the present application optimizes the strike-slip fault identification based on the above embodiment.

[0049] like Figure 2 As shown, the method of the embodiment of the present application specifically includes the following steps:

[0050] S210, constructing a simulation model based on the cross-sectional image information of the physical geological model; the physical geological model reflects the geological information of the target area.

[0051] S220, slicing the simulation model to obtain slice image information.

[0052] The slice image information reflects the information contained in the cross-sectional image of the simulation model, and the slice image information can be obtained by computer slicing the simulation model. The computer slicing refers to using computer slicing technology to simulate the simulation model and obtain the sliced ​​simulation model. The angle of slicing and the number of slicing are not limited in the embodiment of the present application. After obtaining the sliced ​​simulation model, the image information of each section is the slice image information.

[0053] S230, performing strike-slip fault identification on the slice image information, and determining whether a strike-slip fault exists in the basement layer according to the identification result.

[0054] Specifically, in each slice image, a slice image including the intersection area of ​​the salt rock and the basement layer can be selected for strike-slip fault identification. The above slice image can more clearly reflect the occurrence of the strike-slip fault, which is conducive to the identification of the strike-slip fault. In another feasible embodiment, the development position of the strike-slip fault is determined in advance, and the target slice image information containing the development position is determined in each slice image information, and then the strike-slip fault is identified on the target slice image information.

[0055] In an embodiment of the present application, optionally, slicing the simulation model to obtain slice image information includes: slicing the simulation model along a first cutting plane to obtain candidate slice image information; the first cutting plane is perpendicular to the virtual extrusion direction of the simulation model; the virtual extrusion direction of the simulation model corresponds to the extrusion direction of the physical geological model during the construction of the physical geological model. Performing strike-slip fault identification on the slice image information, and determining whether there is a strike-slip fault in the basement layer based on the identification result, includes: performing strike-slip fault identification on the candidate slice image information, and determining whether there is a strike-slip fault in the basement layer based on the identification result.

[0056] In the embodiment of the present application, the first cutting plane reflects the plane of cutting the simulation model, the number of the first cutting planes may be multiple, and the first cutting plane may be a plane perpendicular to the virtual extrusion direction of the simulation model. The virtual extrusion direction of the simulation model corresponds to the extrusion direction of the physical geological model in the process of constructing the physical geological model, which can be understood as follows: the extrusion direction of the physical geological model is relative to the physical geological model, and after the simulation model corresponding to the physical geological model is constructed, its extrusion direction is reflected as the virtual extrusion direction on the simulation model.

[0057] Specifically, the geological information reflected by the first cutting plane is relatively rich, and the geological structure of the basement layer is relatively clear and complete, so the slice image information obtained by slicing the simulation model along the first cutting plane is determined as the candidate slice image information, and then the strike-slip fault is identified based on the candidate slice image information to obtain a clearer and more complete identification result.

[0058] In an embodiment of the present application, optionally, strike-slip fault identification is performed on the slice image information, and based on the identification result, it is determined whether there is a strike-slip fault in the basement layer, including: if it is determined that in the slice image information, there is a misalignment in the color band at a pre-calibrated observation position, then the identification result is determined to be that there is a strike-slip fault in the basement layer; if it is determined that in the slice image information, there is no misalignment in the color band at the pre-calibrated observation position, then the identification result is determined to be that there is no strike-slip fault in the basement layer.

[0059] Among them, the pre-calibrated observation position can be determined according to actual conditions. For example, the preset interval of the slice image information from bottom to top, the observation position is the basement layer position, and the observation position can also be the development position of the strike-slip fault.

[0060] Furthermore, the color bands come from the fact that the quartz sand used to construct the physical geological model has various colors, that is, before the physical geological model is constructed, the color bands at the same height are the same, and the color bands at different heights are different. After the physical geological model is obtained by extrusion, the color bands may be misaligned. If it is determined that the color bands at the pre-calibrated observation positions in the slice image information are misaligned (there are more than two pixel values ​​in a certain height interval (the slice image information is a black and white image), or the pixel values ​​in the same height interval jump, etc.), it is determined that there are strike-slip faults in the basement layer, that is, thick-skinned strike-slip structures; if it is determined that the color bands at the pre-calibrated observation positions in the slice image information are not misaligned, it is determined that there are no strike-slip faults in the basement layer, that is, thin-skinned strike-slip structures.

[0061] For example, the schematic diagram of the basal layer position of the slice image is as follows Figure 3 shown.

[0062] Furthermore, when the strike-slip fault in the saline basin is a thin-skinned strike-slip structure, the subsalt basement layer does not participate in the deformation of the strike-slip structure, and the basement remains intact and regular. It can be further inferred that the evolution of this strike-slip structure has no impact and transformation on the deep subsalt oil and gas traps, and has not caused the destruction of the oil and gas traps. When the strike-slip fault in the saline basin is a thick-skinned strike-slip structure, the subsalt basement layer participates in the deformation of the strike-slip structure, and the basement is no longer intact. It can be further inferred that the evolution of this strike-slip structure may have an impact on the deep subsalt oil and gas traps, that is, the oil and gas traps may be destroyed.

[0063] The technical solution of the embodiment of the present application includes: constructing a simulation model based on the cross-sectional image information of the physical geological model; the physical geological model reflects the geological information of the target area; slicing the simulation model to obtain slice image information; performing strike-slip fault identification on the slice image information, and determining whether there is a strike-slip fault in the basement layer based on the identification result. The technical solution can clearly determine whether there is a strike-slip fault in the basement layer by performing strike-slip fault identification on the slice image information, and because the simulation model can be reused, slice image information at various angles can be obtained, making the identification of strike-slip faults more accurate.

[0064] In an embodiment of the present application, optionally, before constructing a simulation model based on the cross-sectional image information of the physical geological model, the method further includes: cutting the physical geological model along a second cutting plane to obtain the cross-sectional image information of the physical geological model; the normal vector of the second cutting plane is perpendicular to the extrusion direction of the physical geological model in the process of constructing the physical geological model.

[0065] The second cutting plane is a cutting plane of the physical geological model, the normal vector of the second cutting plane is perpendicular to the extrusion direction of the physical geological model in the process of constructing the physical geological model, and the number of the second cutting planes can be multiple, which is not limited in the embodiment of the present application. Compared with planes cut at other angles, the second cutting plane contains more geological information, so that the simulation model constructed subsequently can reflect more geological information.
