Description

Technical Field

[0001] The invention relates to the field of geophysical exploration technology, and in particular to a method and device for stretching and displaying a layer block of a seismic three-dimensional layer model. Background Art

[0002] In the process of constructing a seismic three-dimensional layer model, multiple steps are required, and each step has a great impact on the result. First, the layer needs to be picked. One survey line needs to pick more than ten layers, and one line is manually picked every dozens of lines; after the picking is completed, the layers with the same number need to be interpolated into layer planes. Secondly, the layer planes need to be extrapolated until the layer planes intersect to form intersection lines. Different intersection lines enclose the layers into different spaces, which are called blocks. Different blocks are combined into a layer model.

[0003] In the process of quality control of the horizon model, it is necessary to check the intersection lines and horizon planes of each block in three-dimensional space. The horizon blocks of the seismic three-dimensional horizon model are usually displayed by stretching the model blocks. If an abnormality is found, it is necessary to return to the previous stage and re-pick the horizon, or re-interpolate, extrapolate and close the horizon.

[0004] Currently, when a model block is stretched, a stretching ruler is provided. When the ruler moves, each layer block is stretched in all directions based on the center of the physical model. The model stretching ratio is fixed, which is not conducive to observing the layer block in detail from a certain direction. Summary of the invention

[0005] In view of this, the present invention provides a method and device for stretching and displaying layer blocks of a seismic three-dimensional layer model, an electronic device and a computer-readable storage medium.

Moreover, the present invention may take the form of a computer program product implemented on one or more computer-usable storage media (including but not limited to disk storage, CD-ROM, optical storage, etc.) containing computer-usable program code.

[0078] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present application and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or apparatuses.

[0079] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0080] At present, when stretching the layer blocks of the seismic three-dimensional layer model, a stretching ruler is provided. When the ruler moves, each layer block is stretched in all directions based on the center of the physical model. Among them, the stretching ratio of the model is fixed, which is not conducive to observing the situation of the layer block in detail from a certain direction.

[0081] To solve the above technical problems, the embodiments of the present invention provide a method and device for stretching and displaying layer blocks of a seismic three-dimensional layer model, an electronic device, and a computer-readable storage medium. The stretching display parameters (i.e., the stretching ratio) are adjusted according to the user's stretching display instructions, that is, the user can make adjustments according to actual needs, which is conducive to observing the situation of the layer block separately and in detail from a certain direction, facilitates the quality control of the physical model, and promptly discovers voids or abnormal conditions on the layer surface.

[0082] In view of this, the present application provides a seismic three-dimensional layer model layer block stretching display device, which can be a server S1, see Figure 1, the server S1 can be connected to at least one client device B1 in communication, the client device B1 can send the set stretching parameters to the server S1, and the server S1 can receive the stretching parameters online. The server S1 can pre-process the seismic three-dimensional layer model online or offline, determine the center point of the seismic three-dimensional layer model, the seismic three-dimensional layer model includes multiple layer blocks; construct a three-dimensional coordinate system with the center point of the seismic three-dimensional layer model as the origin; determine the center point coordinates of the layer block in the three-dimensional coordinate system; calculate the target center point position of the layer block according to the center point coordinates of the layer block and the preset stretching parameters; move the layer block according to the target center point position of the layer block, so that the center point of the layer block moves to the target center point position, and feed back the stretched model to the client device B1.

[0083] Also, see Figure 2 The server S1 may also be connected to at least one database server S2 for communication, and the database server S2 is used to store the three-dimensional earthquake layer model. The database server S2 sends the three-dimensional earthquake layer model to the server S1 online, and the server S1 may receive the three-dimensional earthquake layer model online.

[0084] It is understandable that the client device B1 may include a smart phone, a tablet electronic device, a network set-top box, a portable computer, a desktop computer, a personal digital assistant (PDA), a vehicle-mounted device, a smart wearable device, etc. Among them, the smart wearable device may include smart glasses, a smart watch, a smart bracelet, etc.

[0085] The server and the client device may communicate using any suitable network protocol, including network protocols that have not yet been developed on the date of filing this application. The network protocol may include, for example, TCP / IP protocol, UDP / IP protocol, HTTP protocol, HTTPS protocol, etc. Of course, the network protocol may also include, for example, RPC protocol (Remote Procedure Call Protocol) and REST protocol (Representational State Transfer) used on top of the above protocols.

[0086] Among them, the earthquake three-dimensional stratigraphic model stratigraphic block stretching and display device can also be implemented by using a computer that already has an earthquake three-dimensional stratigraphic model. The computer directly receives the user's stretching display instructions and stretches and displays the stratigraphic blocks of the earthquake three-dimensional stratigraphic model.

[0087] Figure 3 Schematic diagram of the process of stretching and displaying the stratum block of the earthquake 3D stratum model in the embodiment of the present invention Figure 1 .like Figure 3 As shown, the seismic three-dimensional layer model layer block stretching display method includes the following contents:

[0088] Step S100: determining the center point of a three-dimensional seismic horizon model, wherein the three-dimensional seismic horizon model includes a plurality of horizon blocks.

[0089] Among them, in the three-dimensional work area, the layers are picked, interpolated into surfaces, and closed into bodies to form a seismic three-dimensional layer model, and the seismic three-dimensional layer model is block stretched and displayed for quality control of the entity model.

[0090] Specifically, the seismic 3D layer model is usually a three-dimensional regular cuboid, and the center of the cuboid can be used as the center point of the seismic 3D layer model. Alternatively, when the seismic 3D layer model is an irregular shape, the seismic 3D layer model can be used as an irregular shape with uniform mass distribution, and the center of gravity of the seismic 3D layer model can be used as the center point of the seismic 3D layer model.

[0091] Among them, the method for determining the center of gravity can be obtained by using a surface uniform grid division method.

[0092] Specifically, the irregular shape is divided into multiple small grids using straight lines, and a straight line with the same number of grids on both sides of the straight line is found through a computer. The irregular shape is changed in another direction, and a straight line that satisfies the above adjustment is found again. The intersection of the two straight lines can be identified as the center of the irregular shape.

[0093] Of course, the above is only an exemplary method of using a computer to determine the center of gravity of an irregular shape. There are many software or algorithms in the prior art that use a computer to determine the center of gravity of an irregular shape, which will not be described in detail here.

[0094] Step S200: constructing a three-dimensional coordinate system with the center point of the three-dimensional seismic horizon model as the origin.

[0095] Among them, because the embodiment of the present invention focuses on stretching each layer block at a certain ratio when stretching and displaying, the unit coordinate length of the three-dimensional coordinate system can be determined in proportion based on the actual size, or the unit can be set according to the display of the seismic three-dimensional layer model. The embodiment of the present invention does not limit this.

[0096] Step S300: Determine the center point coordinates of the layer block in the three-dimensional coordinate system.

[0097] Each layer block is of irregular shape, which is regarded as an irregular shape with uniform mass distribution, and its center of gravity is taken as its center point.

[0098] Step S400: Calculating the target center point position of the layer block according to the center point coordinates of the layer block and the preset stretching parameters;

[0099] The stretching parameter represents the stretching display mode. The stretching display has three modes, including: a stretching display mode along the survey line direction, a stretching display mode along the depth direction, and a stretching display mode along the survey line direction and the depth direction at the same time.

[0100] Step S500 moves the layer block according to the target center point position of the layer block, so that the center point of the layer block moves to the target center point position.

[0101] Stretched display refers to the process of moving the center of gravity of the layer block away from the center of the solid model in a certain direction, with the boundary of the block as the interface. During the stretching display process, the size and boundary surface of the layer block do not change, only the position of the layer block changes.

[0102] Through the above technical scheme, it can be known that the method for stretching and displaying the stratigraphic blocks of the seismic three-dimensional stratigraphic model provided by the embodiment of the present invention allows the user to adjust the moving step size of each stratigraphic block according to actual needs, so that each stratigraphic block is three-dimensionally scattered outward with the center of the model as the center, which is conducive to observing the situation of the stratigraphic block separately and in detail from a certain direction, facilitates the quality control of the physical model, and promptly discovers the void phenomenon or abnormal situation of the stratigraphic surface.

[0103] It can be understood by those skilled in the art that, in the process of stretching the three-dimensional layer entity model block of seismic exploration, different stretching parameters are set for different directions. Since seismic data acquisition is based on survey lines, usually, the layer surface is obtained by interpolation and extrapolation between survey lines. In the process of stretching the entity model, the entity model block is often only stretched and displayed in two directions along the survey line direction and along the depth direction (i.e., the X-axis direction and the Z-axis direction of the coordinate). Therefore, setting the stretching display parameters along the survey line direction and along the depth direction can meet the application requirements, reduce the complexity of the method, and facilitate implementation and application.

[0104] Usually, because the orientation of each layer block to the center of the cuboid is different, the result of stretching shows that each layer block is centered on the center and spreads outward in three dimensions. Figure 4 The seismic 3D horizon model before stretching is shown. Figure 5 The seismic three-dimensional stratigraphic model after stretching is shown.

[0105] Figure 6 Schematic diagram of the process of stretching and displaying the stratum block of the earthquake 3D stratum model in the embodiment of the present invention Figure 2 .like Figure 6 As shown, the seismic three-dimensional layer model layer block stretching display method includes Figure 3 In addition to the steps shown, you may also include:

[0106] Step S10: respectively setting a preset stretching parameter in the X-axis direction, a preset stretching direction in the Y-axis direction, and a preset stretching parameter in the Z-axis direction.

[0107] Among them, the preset stretching parameter in the X-axis direction, the preset stretching direction in the Y-axis direction, and the preset stretching parameter in the Z-axis direction are all greater than or equal to 1. When the stretching parameter is equal to 1, it indicates that no stretching display is performed in this direction.

[0108] Specifically, the preset stretching parameters in the X-axis direction are used to control the speed at which the layer block moves to both sides along the survey line direction. The preset stretching parameters in the Z-axis direction are used to control the speed at which the layer block moves to both sides along the depth direction.

[0109] By setting the stretching parameters along the test direction and along the depth direction, the stretching display of the layer blocks in the solid model can be controlled, which is convenient for users to control the quality of the solid model. The present invention can be well applied in the process of constructing a three-dimensional solid model for seismic exploration.

[0110] Figure 7 Schematic diagram of the process of stretching and displaying the stratum block of the earthquake 3D stratum model in the embodiment of the present invention Figure 3 .like Figure 7 As shown, the seismic three-dimensional layer model layer block stretching display method includes Figure 3 In addition to the steps shown, you may also include:

[0111] Step S250: Acquire the center point of each layer block in the seismic three-dimensional layer model.

[0112] Specifically, each layer block is an irregular shape. It is regarded as an irregular shape with uniform mass distribution and its center of gravity as its center point. It can be obtained by using a surface uniform meshing method. Please refer to the above for details and will not be repeated here.

[0113] Figure 8 Shows Figure 3 , Figure 6 , Figure 7 The specific steps of step S400 in FIG. Figure 8 The step S400 may specifically include the following contents:

[0114] Step S410: multiplying the x-coordinate value of the center point of the layer block by a preset stretching parameter in the X-axis direction to obtain the x-coordinate of the target center point position of the layer block;

[0115] Step S420: multiplying the y coordinate value of the center point of the layer block by a preset stretching parameter in the Y-axis direction to obtain the y coordinate of the target center point position of the layer block;

[0116] Step S430: The z coordinate of the target center point position of the layer block is obtained by multiplying the z coordinate value of the center point of the layer block by a preset stretching parameter in the Z-axis direction.

[0117] Fig. 9 Shows Figure 3 , Figure 6 , Figure 7 The specific steps of step S300 in FIG. Fig. 9 As shown, step S300 may specifically include the following contents:

[0118] Step S310: obtaining the projection length of the center point of the layer block in the X-axis direction of the three-dimensional coordinate system as the x-coordinate of the center point;

[0119] Step S320: Obtain the projection length of the center point of the layer block in the Y-axis direction of the three-dimensional coordinate system as the y-coordinate of the center point;

[0120] Step S330: Obtain the projection length of the center point of the layer block in the Z-axis direction of the three-dimensional coordinate system as the z-coordinate of the center point.

[0121] Based on the same inventive concept, the embodiment of the present application also provides a seismic three-dimensional layer model layer block stretching display device, which can be used to implement the method described in the above embodiment, as described in the following embodiment. Since the principle of solving the problem by the seismic three-dimensional layer model layer block stretching display device is similar to the above method, the implementation of the seismic three-dimensional layer model layer block stretching display device can refer to the implementation of the above method, and the repeated parts will not be repeated. As used below, the term "unit" or "module" can be a combination of software and / or hardware that implements predetermined functions. Although the device described in the following embodiments is preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceived.

[0122] Fig.10 It is a structural frame of the earthquake three-dimensional layer model layer block stretching display device in the embodiment of the present invention. Figure 1 .like Fig.10 As shown, the seismic three-dimensional layer model layer block stretching display device may include: a model center point determination module 10, a coordinate system construction module 20, a layer block center point coordinate determination module 30, a target position determination module 40 and a movement control module 50.

[0123] The model center point determination module 10 determines the center point of the seismic three-dimensional layer model, and the seismic three-dimensional layer model includes a plurality of layer blocks.

[0124] Among them, in the three-dimensional work area, the layers are picked, interpolated into surfaces, and closed into bodies to form a seismic three-dimensional layer model, and the seismic three-dimensional layer model is block stretched and displayed for quality control of the entity model.

[0125] Specifically, the seismic 3D layer model is usually a three-dimensional regular cuboid, and the center of the cuboid can be used as the center point of the seismic 3D layer model. Alternatively, when the seismic 3D layer model is an irregular shape, the seismic 3D layer model can be used as an irregular shape with uniform mass distribution, and the center of gravity of the seismic 3D layer model can be used as the center point of the seismic 3D layer model.

[0126] Among them, the method for determining the center of gravity can be obtained by using a surface uniform grid division method.

[0127] Specifically, the irregular shape is divided into multiple small grids using straight lines, and a straight line with the same number of grids on both sides of the straight line is found through a computer. The irregular shape is changed in another direction, and a straight line that satisfies the above adjustment is found again. The intersection of the two straight lines can be identified as the center of the irregular shape.

[0128] Of course, the above is only an exemplary method of using a computer to determine the center of gravity of an irregular shape. There are many software or algorithms in the prior art that use a computer to determine the center of gravity of an irregular shape, which will not be described in detail here.

[0129] The coordinate system construction module 20 constructs a three-dimensional coordinate system with the center point of the seismic three-dimensional layer model as the origin.

[0130] The layer block center point coordinate determination module 30 determines the center point coordinates of the layer block in the three-dimensional coordinate system.

[0131] Each layer block is of irregular shape, which is regarded as an irregular shape with uniform mass distribution, and its center of gravity is taken as its center point.

[0132] The target position determination module 40 calculates the target center point position of the layer block according to the center point coordinates of the layer block and preset stretching parameters.

[0133] The stretching parameter represents the stretching display mode. The stretching display has three modes, including: a stretching display mode along the survey line direction, a stretching display mode along the depth direction, and a stretching display mode along the survey line direction and the depth direction at the same time.

[0134] The movement control module 50 moves the layer block according to the target center point position of the layer block, so that the center point of the layer block moves to the target center point position.

[0135] Stretched display refers to the process of moving the center of gravity of the layer block away from the center of the solid model in a certain direction, with the boundary of the block as the interface. During the stretching display process, the size and boundary surface of the layer block do not change, only the position of the layer block changes.

[0136] Through the above technical scheme, it can be known that the three-dimensional earthquake stratigraphic model stratigraphic block stretching display device provided by the embodiment of the present invention allows the user to adjust the moving step size of each stratigraphic block according to actual needs, so that each stratigraphic block is three-dimensionally scattered outward with the center of the model as the center, which is conducive to observing the situation of the stratigraphic block separately and in detail from a certain direction, facilitates the quality control of the physical model, and timely discovers the void phenomenon or abnormal situation of the stratigraphic surface.

[0137] It can be understood by those skilled in the art that, in the process of stretching the three-dimensional layer entity model block of seismic exploration, different stretching parameters are set for different directions. Since seismic data acquisition is based on survey lines, usually, the layer surface is obtained by interpolation and extrapolation between survey lines. In the process of stretching the entity model, the entity model block is often only stretched and displayed in two directions along the survey line direction and along the depth direction (i.e., the X-axis direction and the Z-axis direction of the coordinate). Therefore, setting the stretching display parameters along the survey line direction and along the depth direction can meet the application requirements, reduce the complexity of the method, and facilitate implementation and application.

[0138] Usually, because the orientations of the various layer blocks to the center of the cuboid are different, the result of stretching shows that the various layer blocks spread out in three dimensions with the center as the center.

[0139] Fig.11 It is a structural frame of the earthquake three-dimensional layer model layer block stretching display device in the embodiment of the present invention. Figure 2 ;like Fig.11 As shown, the earthquake three-dimensional layer model layer block stretching display device includes Fig.10 Based on the seismic three-dimensional layer model layer block stretching display device shown, it can also include: a stretching parameter setting module 60.

[0140] The stretching parameter setting module 60 sets the preset stretching parameters in the X-axis direction, the preset stretching direction in the Y-axis direction, and the preset stretching parameters in the Z-axis direction respectively.

[0141] Among them, the preset stretching parameter in the X-axis direction, the preset stretching direction in the Y-axis direction, and the preset stretching parameter in the Z-axis direction are all greater than or equal to 1. When the stretching parameter is equal to 1, it indicates that no stretching display is performed in this direction.

[0142] Specifically, the preset stretching parameters in the X-axis direction are used to control the speed at which the layer block moves to both sides along the survey line direction. The preset stretching parameters in the Z-axis direction are used to control the speed at which the layer block moves to both sides along the depth direction.

[0143] By setting the stretching parameters along the test direction and along the depth direction, the stretching display of the layer blocks in the solid model can be controlled, which is convenient for users to control the quality of the solid model. The present invention can be well applied in the process of constructing a three-dimensional solid model for seismic exploration.

[0144] In an optional embodiment, the seismic three-dimensional horizon model horizon block stretching display device may further include: a horizon block center point acquisition module 70.

[0145] The layer block center point acquisition module 70 acquires the center point of each layer block in the seismic three-dimensional layer model.

[0146] Specifically, each layer block is an irregular shape. It is regarded as an irregular shape with uniform mass distribution and its center of gravity as its center point. It can be obtained by using a surface uniform meshing method. Please refer to the above for details and will not be repeated here.

Fig.12 As shown, the target position determination module 40 may include: a target position x-coordinate determination unit 41 , a target position y-coordinate determination unit 42 , and a target position z-coordinate determination unit 43 .

[0148] The target position x-coordinate determining unit 41 obtains the x-coordinate of the target center point of the layer block by multiplying the x-coordinate value of the center point of the layer block by a preset stretching parameter in the X-axis direction;

[0149] The target position y coordinate determining unit 42 obtains the y coordinate of the target center point position of the layer block by multiplying the y coordinate value of the center point of the layer block by a preset stretching parameter in the Y-axis direction;

[0150] The target position z coordinate determining unit 43 obtains the z coordinate of the target center point position of the layer block by multiplying the z coordinate value of the center point of the layer block by a preset stretching parameter in the Z-axis direction.

Fig.13 As shown, the layer center point coordinate determination module 30 may include: a layer block center point x coordinate determination unit 31, a layer block center point y coordinate determination unit 32 and a layer block center point z coordinate determination unit 33.

[0152] The layer block center point x-coordinate determining unit 31 obtains the projection length of the center point of the layer block in the x-axis direction of the three-dimensional coordinate system as the x-coordinate of the center point;

[0153] The y coordinate determining unit 32 of the center point of the layer block obtains the projection length of the center point of the layer block in the Y-axis direction of the three-dimensional coordinate system as the y coordinate of the center point;

[0154] The layer block center point z coordinate determining unit 33 obtains the projection length of the center point of the layer block in the Z-axis direction of the three-dimensional coordinate system as the z coordinate of the center point.
