Description

Technical Field

[0001] This invention relates to the field of geological exploration technology, and in particular to a method, apparatus, equipment and medium for determining the location of fractured bodies. Background Technology

[0002] With the rapid development of geological exploration technology, fault-deposition bodies, as important reservoirs and oil and gas migration channels, require the acquisition of their location.

[0003] Currently, seismic exploration technology is used to analyze seismic profiles to determine the location of fault-knot bodies.

[0004] However, the above methods cannot determine the stratigraphic position of the fault-dissolved body, cannot determine the development of the fault-dissolved body in unknown strata, and cannot obtain the spatial relationship between the fault-dissolved body and the stratigraphic line. Summary of the Invention

[0005] This invention provides a method, apparatus, device, and medium for determining the location of a fractured solution. The embodiments of this invention can obtain the stratigraphic information of the fractured solution and determine the positional relationship between the fractured solution and the stratigraphic position.

[0006] In a first aspect, embodiments of the present invention provide a method for determining the location of a broken solution, the method comprising:

[0010] Based on the location of each stratum line and the region of each broken solution, determine the spatial relationship between each stratum line and each broken solution.

[0020] Fourthly, embodiments of the present invention also provide a computer-readable storage medium storing computer instructions, which are used to cause a processor to execute the method for determining the location of a broken body according to any embodiment of the present invention.

[0021] The technical solution of this invention, by acquiring multiple seismic profiles and ensuring that the seismic profiles are parallel but not on the same plane, can better reflect the three-dimensional spatial distribution characteristics of the horizon lines and fault-soluble bodies. By identifying the positions of the horizon lines and the regions of the fault-soluble bodies in the seismic profiles, the spatial relationship between the fault-soluble bodies and the horizons can be analyzed based on the positions of each horizon line and the regions of each fault-soluble body, thereby determining the specific horizon where the fault-soluble body is located.

[0032] Figure 1 This is a flowchart illustrating a method for determining the location of a broken solution according to an embodiment of the present invention. This embodiment is applicable to situations involving the determination of the location of a broken solution. The method can be executed by a device for determining the location of a broken solution, which can be implemented in hardware and / or software.

[0033] See Figure 1 The method for determining the location of the broken solution, as shown, includes:

[0034] S101. Obtain multiple seismic profile images; wherein the seismic profiles in each seismic profile image are parallel and not on the same plane.

[0035] A seismic profile can be a longitudinal two-dimensional slice image of an underground geological structure. Seismic profiles are generated by recording the reflected waves as seismic waves propagate underground and are reflected or refracted at stratigraphic interfaces, using seismic imaging algorithms. The longitudinal direction can be perpendicular to the Earth's surface, and the transverse direction can be parallel to the Earth's surface.

[0036] In this context, the parallelism and non-plane nature of the seismic profiles means that while they are parallel in the longitudinal direction, they do not overlap in the same two-dimensional longitudinal plane. Each seismic profile represents a slice perpendicular to the Earth's surface. By correctly stitching these slices together according to the survey line positions and spacing, the three-dimensional geological structure can be reconstructed in three-dimensional space. The gaps between the seismic profiles indicate unexplored areas, which can be filled in using interpolation algorithms to complete the geological structure of these unexplored areas.

[0037] S102. Identify the location of at least one horizon line in each seismic profile.

[0038] The location of a bedding line refers to the position of a line marking the relationship between specific strata in a seismic profile. Different strata are separated by bedding lines, and by identifying the location of bedding lines in each seismic profile, the location of different strata can be determined. A seismic profile reflects the underground geological structure; therefore, at least one bedding line exists in a seismic profile. The embodiments of this application can identify the location of one bedding line or the location of multiple bedding lines.

[0039] In a specific example, identifying the location of a horizon line in each seismic profile can be achieved through the following steps:

[0040] 1) Randomly select X seismic profiles from the various seismic profile maps. Add manually interpreted horizon labels to these X profiles, i.e., manually mark the locations of horizon lines. The locations of the manually marked horizon lines can be represented by a binary matrix of the same size as the seismic profile map, with binary values ​​including 0 and 1. A value of 1 indicates that the point is a horizon line, and a value of 0 indicates other locations. Use the seismic profile maps with manually interpreted horizon labels as training samples.

[0041] 2) Input the training samples into the deep learning model, perform Gaussian blurring on the positions of manually labeled layer lines in the training samples, add a weak supervision mechanism and a representation learning mechanism during the training process, and adjust the deep learning model according to the manually interpreted layer labels in the training samples to obtain a pre-trained deep learning model; among them, the deep learning model can be U-Net (U-shaped Convolutional Neural Network).

[0042] 3) Input each seismic profile into the pre-trained deep learning model to obtain the layer probability volume of each seismic profile. The layer probability volume can be a two-dimensional matrix of the probability values ​​of each location point in each seismic profile as a layer line. The value of each element in the two-dimensional matrix represents the probability value of each location point as a discrete point on the layer line, and the value range of each element is 0-1.

[0043] 4) Generate stratigraphic lines in each stratigraphic probability volume according to the position with the highest probability value, and generate stratigraphic files; whereby a stratigraphic file can refer to a file that records the coordinates of discrete points of the stratigraphic lines.

[0044] 5) The horizon file is processed as follows: First, the horizon lines are aligned according to seismic facies characteristics, including crests, troughs, or zero phase; second, the horizon lines are broken at fault locations; then, the horizon lines are smoothed; finally, the processed horizon file is generated, which can be used to identify the position of the horizon lines in each seismic profile.

[0045] By stitching together the various seismic profiles, the horizon lines in each profile can form horizon planes. When it is necessary to identify the positions of multiple horizon lines in various seismic profiles, the vertical coordinates of horizon lines on the same horizon plane in adjacent seismic profiles fluctuate within a certain threshold range. Therefore, the positions of multiple horizon lines can be identified.

[0046] S103. Identify the regions where the dissolution is interrupted in each seismic profile.

[0047] The term "fault-dissolution body" refers to the area of ​​an abnormal geological body formed by fracture or dissolution within the strata. Fault-dissolution bodies are irregularly shaped. They only appear when specific tectonic movements or dissolution occur; therefore, not all seismic profiles contain fault-dissolution bodies. It is only necessary to identify the areas containing fault-dissolution bodies in each seismic profile.

[0048] In a specific example, identifying regions containing fault-fused karst structures in various seismic profiles can be achieved through the following steps:

[0049] 1) Select X seismic profiles containing fault-knot bodies from the various seismic profile maps. Add artificial attribute value labels to these X seismic profiles, that is, assign an attribute value to each location, with the attribute value ranging from 0 to 1000. Areas with fault-knot bodies are labeled with attribute values ​​of 800-1000, while other geological areas are labeled with attribute values ​​of 0-799. It is possible to selectively identify fault-knot body areas of a certain size; that is, when adding artificial attribute value labels, only fault-knot bodies with a length less than M meters and a width less than N meters are labeled. Use the seismic profiles with artificial attribute value labels as training samples.

[0050] 2) Input each seismic profile into the deep learning model, and adjust the deep learning model according to the artificial attribute value labels in the training samples to obtain a pre-trained deep learning model; the deep learning model can be an end-to-end convolutional neural network.

[0051] 3) Input each seismic profile into the pre-trained deep learning model to obtain the attribute value distribution volume of each seismic profile. The attribute value distribution volume can be a two-dimensional matrix of the attribute values ​​of mass points in each location in the seismic profile. The value of each element in the two-dimensional matrix represents the attribute value of each location point.

[0052] 4) In each attribute value distribution volume, the location points with attribute values ​​greater than 800 are identified as the areas of the fault-dissolved body, thereby realizing the identification of the areas of the fault-dissolved body in each seismic profile.

[0053] S104. Determine the spatial relationship between each stratum line and each broken solution body based on the position of each stratum line and the region of each broken solution body.

[0054] Spatial positional relationships refer to the relative positions of each stratigraphic line and each fractured solution body in three-dimensional space. These relationships can include differences in distance, azimuth, relative height, or depth between the stratigraphic lines and fractured solutions; they can also include whether a stratigraphic line intersects or contacts a fractured solution body, and whether the stratigraphic line is truncated by a fractured solution body. By determining the spatial positional relationships between each stratigraphic line and each fractured solution body, it is possible to more accurately determine which specific stratigraphic layer the fractured solution body is located in, or which stratigraphic line the fractured solution body intersects with.

[0055] As can be seen, in the embodiments of the present invention, by acquiring multiple seismic profiles and ensuring that the seismic profiles are parallel but not on the same plane, the three-dimensional spatial distribution characteristics of the horizon lines and fault-soluble bodies can be better reflected; by identifying the position of the horizon lines and the region of the fault-soluble bodies in the seismic profiles, the spatial relationship between the fault-soluble bodies and the horizons can be analyzed based on the position of each horizon line and the region of each fault-soluble body, thereby determining the specific horizon where the fault-soluble body is located.

[0056] The process of "determining the spatial relationship between each horizon line and each fault-knot body based on the location of each horizon line and the region of each fault-knot body" is refined into "generating a three-dimensional bedding line model corresponding to each horizon line based on the location of each horizon line in each seismic profile and the relative spatial position between the seismic profiles corresponding to each seismic profile; generating a top-view bedding line map corresponding to each horizon line based on the three-dimensional bedding line model corresponding to each horizon line; generating a three-dimensional fault-knot body model based on the region of each fault-knot body in each seismic profile and the relative spatial position between the seismic profiles corresponding to each seismic profile; generating a top-view fault-knot body map based on the three-dimensional fault-knot body model; and determining the spatial relationship between each horizon line and each fault-knot body based on the top-view fault-knot body map and the top-view bedding line map corresponding to each horizon line," in order to improve the operation of the fault-knot body location determination method.

[0057] It should be noted that for parts not described in detail in the embodiments of the present invention, please refer to the descriptions in other embodiments. Figure 2 A flowchart of a method for determining the location of a broken solution provided in an embodiment of the present invention.

[0058] See Figure 2 The method for determining the location of the broken solution, as shown, includes:

[0059] S201. Obtain multiple seismic profile images; wherein the seismic profiles in each seismic profile image are parallel and not on the same plane.

[0060] S202. Identify the location of at least one horizon line in each seismic profile.

[0061] S203. Identify the regions where the dissolution is interrupted in each seismic profile.

[0062] S204. Based on the position of each layer line in each seismic profile and the relative spatial position between the seismic profiles corresponding to each seismic profile, generate a three-dimensional layer line model corresponding to each layer line.

[0063] In this context, relative spatial position refers to the positional relationship of each seismic profile in three-dimensional space. The seismic profiles are parallel and not on the same plane.

[0064] A 3D bedding plane model refers to a model that forms a continuous bedding plane by using the 3D spatial relationships of the bedding lines in various seismic profiles. The 3D bedding plane model consists of discrete points, each with X, Y, and Z coordinates in 3D space. The model can be constructed in a 3D coordinate system, with the bedding plane located at a longitudinal, irregularly shaped section within that system. Since strata are not perfectly flat, the bedding plane is also not flat. The bedding plane can be a surface formed by interpolating or fitting the bedding lines from each seismic profile, separating two different bedding planes. In one example, a 3D bedding plane model can be generated based on bedding plane and fault files.

[0065] S205. Based on the three-dimensional layer line model corresponding to each layer line, generate the top view layer line diagram corresponding to each layer line.

[0066] A top-view bedding plane can be considered a two-dimensional graphic projected onto a horizontal plane from a three-dimensional bedding plane model. It displays the distribution of bedding planes in horizontal space, including their planar position, direction, shape, and depth. The top-view bedding plane maps the three-dimensional bedding plane model onto the XY plane by ignoring the depth (Z-coordinate) of discrete points within the bedding plane. Because bedding planes are continuous in three-dimensional space, their top-view bedding plane diagrams are also continuous curves. When bedding planes are interrupted due to faults or fractured solutions, the top-view bedding plane diagram will also show an interruption at the corresponding location.

[0067] In a specific example, generating the top-view plan of each level line based on the 3D level line model can be achieved in the following way:

[0068] 1) Calculate the intersection line between the fault plane and each layer plane, and determine the hanging wall and footwall types of the intersection line on both sides of the fault based on the fault properties. The intersection line segment connecting the layers is the three-dimensional fault polygon.

[0069] 2) Based on the range and interval of the contour lines, obtain different elevation depths, traverse each triangle of the layer plane, and determine whether the plane containing all contour elevation values ​​intersects with it. If so, calculate the intersecting line segments according to the three sides of the triangular unit and the elevation values.

[0070] 3) Place all intersecting line segments into the line segment set corresponding to the elevation value. For each elevation value's line segment set, use the principle that the first and last endpoints are the same to trace all the contour line segments of that elevation value, thereby obtaining the set of structural contour lines for that stratum.

[0071] 4) Generate a top-view plan view based on the set of contour lines.

[0072] S206. Generate a three-dimensional fault-collapse model based on the region of each fault-collapse body in each seismic profile and the relative spatial position between the corresponding seismic profiles.

[0073] A three-dimensional fault-knot model refers to a geometric model describing the distribution of fault-knots in three-dimensional space. The three-dimensional fault-knot model displays the complete morphology and distribution location of fault-knots in three-dimensional space, providing fundamental information for geological structural analysis and resource development. By identifying areas containing fault-knots in various seismic profiles, seismic profiles containing fault-knots are obtained, and the relative spatial positions between seismic profiles are combined to generate a three-dimensional fault-knot model.

[0074] In addition, after generating the three-dimensional fractured solution model, the number, volume, volume sorting, planar area, and planar area sorting of the fractured solutions are statistically analyzed.

[0075] S207. Generate a top-view diagram of the fractured solution based on the three-dimensional fractured solution model.

[0076] In this context, a top-view fracture solution diagram refers to a two-dimensional graphic projected onto a horizontal plane from a three-dimensional fracture solution model. The top-view planar line diagram shows the distribution of fracture solutions in horizontal space, including their planar location, orientation, shape, and depth. Through projection transformation, points from the three-dimensional fracture solution model can be mapped onto the XY plane to generate two-dimensional fracture solution boundary lines or region maps.

[0077] S208. Based on the top-view diagram of the fractured solution and the top-view planar line diagram corresponding to each stratum line, determine the spatial relationship between each stratum line and each fractured solution.

[0078] In a specific example, carbonate fault-knot bodies are complexes composed of faults and karst caves. Karstification can erode the surrounding rock along faults to form underground cavities, making fault-knot bodies a crucial type of carbonate oil and gas reservoir. Identifying the spatial relationship between fault-knot bodies and stratigraphic lines helps determine the development of fault-knot bodies in unknown strata, judge their formation age, reveal the interaction between fault-knot bodies and strata, refine the structural characteristics of strata, and evaluate the fluid storage capacity of strata. This supports the prediction of oil and gas reservoirs in carbonate rocks and provides a valid basis for oil and gas reservoir evaluation and well location deployment.

[0079] As can be seen, in this embodiment, by generating a three-dimensional bedding line model based on the location and spatial relationship of the seismic profile, an intuitive representation of the distribution of bedding lines in three-dimensional space can be achieved, facilitating subsequent analysis and processing. By generating a top-view bedding line map of the bedding lines, a simplified expression of the horizontal distribution of the bedding lines can be achieved, which helps to observe the distribution characteristics of the bedding lines from a planar perspective. By constructing a three-dimensional fault-knot body model, the accurate representation of the location of the fault-knot body in three-dimensional space can be achieved. By generating a top-view fault-knot body map of the fault-knot body, a simplified expression of the horizontal distribution of the fault-knot body can be achieved. By combining the top-view bedding line map and the top-view fault-knot body map, a clear analysis of the spatial relationship between the bedding lines and the fault-knot body can be achieved.

[0080] In some embodiments, determining the spatial relationship between each stratum line and each fractured solution based on the top-view fractured solution diagram and the top-view planar line diagram corresponding to each stratum line includes:

[0081] For each stratum line, the top-view stratum line map and the top-view fracture-dissolution map corresponding to the stratum line are aligned and mapped to obtain the aligned projection map corresponding to the stratum line.

[0082] Based on the alignment projection diagram corresponding to the stratigraphic line, determine the spatial relationship between the stratigraphic line and each fractured solution.

[0083] Alignment mapping refers to the process of aligning the top-view fracture surface diagram and the top-view planar line diagram in space under a unified coordinate system or reference datum. Alignment mapping ensures that the top-view fracture surface diagram and the top-view planar line diagram are completely aligned in space, guaranteeing their accurate and reliable relative positions. Geometric operations such as scaling, rotation, and translation can be used to maintain consistency in the spatial position and scale of the top-view fracture surface diagram and the top-view planar line diagram.

[0084] The aligned projection map refers to the resulting map after alignment mapping. It represents the superposition of a top-view bedding plane map and a top-view fracture-solution map in the same coordinate system, used to visually demonstrate the spatial distribution relationship between bedding planes and fracture-solution bodies. Figure 3 This is an aligned projection diagram of a method for determining the location of a broken solution provided in an embodiment of the present invention.

[0085] As can be seen, in this embodiment, by aligning and mapping the top-view bedding plane map and the top-view fault-knot map, a unified representation of the two can be achieved on the same plane, which helps to accurately analyze their relative spatial distribution. By determining the spatial relationship between the bedding plane and the fault-knot based on the aligned projection map, an intuitive quantification of the interaction between geological structures can be achieved, providing data support for further geological analysis.

[0086] In some embodiments, after identifying the regions of discontinuous karst in each seismic profile, the method further includes:

[0087] In the regions of each broken solution, determine the centerline of each broken solution;

[0088] Based on the top-view diagram of fractured solutions and the corresponding top-view planar lines of each stratum, determine the spatial relationship between each stratum and each fractured solution, including:

[0089] Based on the top-view plan of the fractured solution, the spatial relationship between each layer line and each fractured solution is determined.

[0090] The centerline can refer to the geometric center trajectory of the fractured solution region in two-dimensional or three-dimensional space. The centerline reflects the spatial distribution characteristics of the fractured solution region. In a specific example, based on information from the fractured solution attribute values, the center position of the fractured solution region is automatically extracted, and the centerline of the fractured solution is automatically generated along the position with the largest attribute value.

[0091] Since the centerline can reflect the orientation and position of the fault-knot body on the top view plane, by determining the spatial relationship between each layer line and each fault-knot body based on the centerline of each fault-knot body in the top view fault-knot body diagram and the corresponding top view bedding plane diagram, the offset and direction of the fault-knot body relative to the strata can be quickly determined. Complex fault-knot body regions may contain irregular boundaries. By approximating with the centerline, the computational complexity can be greatly reduced, and the geometric relationship between the fault-knot body and the strata can be quickly estimated.

[0092] As can be seen, in this embodiment, by determining the centerline in the fractured solution region, the core features of the fractured solution morphology can be extracted, which facilitates simplified analysis of the fractured solution location and orientation. By comparing the centerline in the top view of the fractured solution with the top view of the stratigraphic line, a more accurate positioning of the spatial relationship between the stratigraphic line and the fractured solution can be achieved, providing support for a detailed description of the geological structure.

[0093] In some embodiments, a three-dimensional bedding line model corresponding to each bedding line is generated based on the position of each bedding line in each seismic profile and the relative spatial position between the seismic profiles corresponding to each seismic profile, including:

[0094] Based on the relative spatial positions between the seismic profiles corresponding to each seismic profile, the seismic profiles are aligned to obtain the aligned seismic profile.

[0095] In the aligned seismic profile, based on the position of each horizon line in each seismic profile, the same horizon lines are connected to generate a three-dimensional horizon line model corresponding to the same horizon line.

[0096] Alignment can refer to the operation of aligning various seismic profiles along the same boundary, integrating them into a unified whole, thereby forming a complete subsurface medium model.

[0097] Connect the horizon lines located on each seismic profile to the horizon lines belonging to the same horizon plane. The connection method can be to connect horizon lines in different seismic profiles using an interpolation algorithm.

[0098] As can be seen, in this embodiment, by aligning seismic profiles, accurate matching of different seismic profiles under a unified spatial coordinate system can be achieved, providing a foundation for subsequent connection of stratigraphic lines and construction of a three-dimensional model. By connecting the same stratigraphic line in the aligned profiles, a three-dimensional reconstruction of the spatial morphology of the stratigraphic line can be achieved, facilitating the three-dimensional display and analysis of the stratigraphic structure.

[0099] In some embodiments, after identifying the location of at least one horizon line in each seismic profile, the method further includes:

[0100] Obtain the fault locations corresponding to each seismic profile;

[0101] The positions of the identified horizon lines are corrected based on the fault locations corresponding to each seismic profile.

[0102] The fault location can refer to its position on the plane interrupted in the seismic profile. Fault locations can be stored in fault files, which include the coordinates of discrete points within the fault location.

[0103] Among them, "correction" can refer to deleting the positions where the stratigraphic line originally belonged to faults when generating stratigraphic lines in the stratigraphic probability volume according to the positions with the highest probability values, and automatically generating stratigraphic lines at the positions that originally belonged to faults.

[0104] As can be seen, in this embodiment, by obtaining the fault location from the seismic profile, the fault characteristics can be accurately located, providing a reference for subsequent adjustments to the horizon lines; by correcting the horizon lines based on the fault location, the accuracy of the horizon line location can be improved, thereby enhancing the reliability of geological interpretation and the accuracy of the model.

[0105] In some embodiments, after determining the spatial relationship between each stratum boundary line and each broken solution body based on the position of each stratum boundary line and the region of each broken solution body, the method further includes:

[0106] Based on the spatial relationship between each stratum line and each broken solution body, the overlap relationship between each broken solution body and each stratum line is detected, and the overlap detection results of each broken solution body are obtained.

[0107] Based on the overlapping detection results of each fractured body, the oil and gas storage and transportation area is determined.

[0108] Among them, the overlapping relationship can refer to the intersection of the fractured solution and the stratigraphic line, that is, the fractured solution is located on the stratigraphic line.

[0109] The overlap detection result can refer to the detection result of whether there is an overlap relationship between the fractured solution and each stratigraphic line. For example, when the fractured solution and the stratigraphic line overlap, the overlap detection result is "overlapping"; when the fractured solution and the stratigraphic line do not overlap, the overlap detection result is "not overlapping".

[0110] In a specific example, when the stratigraphic line overlaps with the cavern area of ​​a fractured solution, the cavern area provides a large volume of storage space, suitable for storing oil and gas, but has poor stability and is not suitable for transporting oil and gas; when the stratigraphic line overlaps with the fractured zone of a fractured solution, the fractured zone provides both storage space and serves as a channel for oil and gas migration, suitable for both storage and transport; when the stratigraphic line overlaps with the high-permeability fractures of a fractured solution, the high-permeability fractures are suitable for transporting oil and gas, but lack sufficient sealing and are not suitable for storing oil and gas; when the stratigraphic line overlaps with the impermeable fault plane of a fractured solution, the impermeable fault plane prevents oil and gas leakage and is part of a natural closed trap, suitable for storing oil and gas, but not suitable for transporting oil and gas; when the stratigraphic line overlaps with the stable boundary zone of a fractured solution, the stable boundary zone is suitable for the construction of long-distance transportation facilities, but has poor storage capacity and is not suitable for storing oil and gas.

[0111] Furthermore, fault zones can serve as reservoirs for oil and gas. Faults connect rocks with good reservoir properties with rocks with good sealing properties, forming a favorable combination of reservoir and sealing. This sealing property can prevent oil and gas from escaping along the fault plane, thus trapping the oil and gas within the reservoir.

[0112] As can be seen, in this embodiment, by detecting the overlap relationship between the fault-dissolved body and the stratigraphic line, the interaction of geological structures can be accurately identified, providing a basis for judging the possible oil and gas storage characteristics of the fault-dissolved body; by determining the oil and gas storage and transportation area based on the overlap detection results, the location and evaluation of potential oil and gas reservoirs can be realized, providing reference support for the development of oil and gas resources.

[0113] In a specific example Figure 4 This invention provides a schematic diagram of a device for determining the location of a broken solution. This invention is applicable to situations requiring the determination of the location of a broken solution. The device can execute a method for determining the location of a broken solution and can be implemented in hardware and / or software.

[0114] See Figure 4 The device for determining the location of fault-fused bodies shown includes: a seismic profile acquisition module 401, a layer line identification module 402, a fault-fused body identification module 403, and a positional relationship determination module 404, wherein...

[0115] The seismic profile acquisition module 401 is used to acquire multiple seismic profiles; wherein the seismic profiles in each seismic profile are parallel and not on the same plane;

[0117] The fault-dissolved body identification module 403 is used to identify the areas of fault-dissolved bodies in each seismic profile.

[0118] The positional relationship determination module 404 is used to determine the spatial positional relationship between each stratum ...

[0119] The technical solution of this invention, by acquiring multiple seismic profiles and ensuring that the seismic profiles are parallel but not on the same plane, can better reflect the three-dimensional spatial distribution characteristics of the horizon lines and fault-soluble bodies.
