Description

Technical Field

[0001] This invention relates to the field of oil and gas field exploration and development technology, and in particular to a method and system for multidimensional data overlay display. Background Technology

[0002] Petroleum resources are an important resource in modern society. In recent years, with the increasing demand for petroleum, the scale of oilfield development has also grown larger. Oilfield development places increasingly higher demands on technology; advanced science and technology are needed to support resource discovery, geological exploration, and oil extraction.

[0003] 3D seismic interpretation, a technique in geophysical exploration, is a three-dimensional interpretation method that uses points, lines, and surfaces to display geological conditions in a three-dimensional manner. In modern oilfield development, 3D seismic interpretation is widely used for predicting underground reservoirs, such as interpreting the trend and morphology of underground strata, the distribution of faults, and the location of reservoirs. The interpretation results require comprehensive analysis and evaluation. Currently, the commonly used method for analyzing interpretation results is that only one type of seismic body data can be displayed on a single seismic profile. For multiple types of seismic data, this method of displaying individual data points one by one cannot simultaneously reflect the multi-dimensional geological characteristics of the target geological body. Therefore, the display of seismic data is relatively one-sided, failing to meet user needs and posing significant difficulties for geologists in analyzing target data. To solve this technical problem, a multi-dimensional data overlay display method and system are proposed. Summary of the Invention

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] The flowchart shown in the attached diagram is for illustrative purposes only and does not necessarily include all content and operations / steps, nor does it necessarily have to be performed in the order described. For example, some operations / steps can be broken down, combined, or partially merged, so the actual execution order may change depending on the actual situation.

[0029] It should be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0030] Specifically, the embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0031] Please see Figure 1 , Figure 1 This is a flowchart of a multi-dimensional data overlay display method provided in an embodiment of the present invention, such as... Figure 1As shown, the multidimensional data overlay display method includes steps S10 to S40.

[0032] S10. Obtain several types of 3D data and input the 3D data in a loop according to the 3D data table for loop format.

[0033] In embodiments of the present invention, the three-dimensional data includes seismic volume data, inversion volume data, and ant-body data. The seismic volume data is the original volume; the inversion volume data is favorable reservoir information calculated from the seismic volume data; and the ant-body data is fault information calculated from the seismic volume data.

[0034] In an embodiment of the present invention, the three-dimensional data is in a three-dimensional data format, and the three-dimensional data includes first-dimensional data, second-dimensional data, and third-dimensional data; the first-dimensional data is a line number, the second-dimensional data is a track number, and the third-dimensional data is time or depth.

[0035] It should be noted that each data table is the same size, meaning that each dimension of data has the same unit points. The number and location of unit points in each three-dimensional data are completely consistent, each reflecting a different value at the same point in space.

[0036] In an embodiment of the present invention, the step of inputting the three-dimensional data in a loop according to the three-dimensional data table for loop format includes: Collect the maximum and minimum values ​​for each dimension of data. For example, the maximum value for line number is Lmax, the minimum value is Lmin, and the number of line numbers is Lmax - Lmin + 1. The maximum value for channel number is Mmax, the minimum value is Mmin, and the number of channel numbers is Mmax - Mmin + 1. Assume the third dimension of data is time, with the maximum value of time sampling points being Tmax, the minimum value being Tmin, and the number of sampling points being Tmax - Tmin + 1.

[0037] Set the for loop condition, create an integer i with an initial value of 1, a step size of 1, and an ending value of LmaxLmin+1; use the line number as the X-axis, with a minimum value of 0 and a maximum value of LmaxLmin+1; use the track number as the Y-axis, with a minimum value of 0 and a maximum value of Mmax-Mmin+1, to form a two-dimensional matrix; the loop steps are: assign the i-th time value to the L(i)Lmin+1-th row and M(i)Mmin+1-th column of the two-dimensional matrix; input in this way until the loop ends; input each three-dimensional data in this way.

[0038] In embodiments of the present invention, the three-dimensional data further includes input layer data. The input layer data is a data table of time or depth sampling points on lines and traces in two dimensions. Each cell in this data table contains the coordinate values ​​of the line, trace, and time / depth sampling points in three dimensions. This coordinate table constitutes a two-dimensional surface slice in the three-dimensional data volume. The input method is consistent with the data volume input.

[0039] In embodiments of the present invention, the three-dimensional data further includes curvature attribute volume data.

[0040] Data preparation, seismic data profiles as follows Figure 2 As shown, purple and blue represent the top surface and atmospheric layer of the Shiniulan Formation, respectively; the cross-section of the Shiniulan Formation inversion data volume is shown below. Figure 3 As shown, the curvature property volume profile is as follows Figure 4 As shown, the body profile of the ant is as follows: Figure 5 As shown; and each type of data must be in a uniform format; such as line number, track number, X coordinate, Y coordinate, start time, etc. for data volumes; and layer data in X coordinate, Y coordinate, Z value format.

[0041] S20. Set several three-dimensional data types, and each three-dimensional data type is different.

[0042] It should be noted that separate types are set for each type of 3D data, such as seismic data as A, inversion data volume as B, and ant volume as C.

[0043] It should be noted that different 3D data represent different meanings, so a different type needs to be defined for each data volume in this step; the specific type is not required. This step lays the foundation for later color adjustments, and each type of data has its own color bar.

[0044] S30. Display each type of 3D data for the completed type settings.

[0045] In an embodiment of the present invention, step S30, displaying each type of 3D data after completing the type setting, includes: Each type of 3D data is sliced, and a 2D profile is displayed based on either the first or second dimension of the data. Seismic volume data is displayed first, followed by profiles of other volume data in sequence.

[0046] It's important to note that 3D data is displayed overlay on a computer screen, similar to layers: there are bottom, middle, and top views. The original volumetric data is displayed at the bottom, while other volumetric data are displayed in the middle or on top as needed.

[0047] For example, open the seismic profile module and open all multidimensional data as shown in Figures 2-5; the seismic data volume profile is shown in Figure 2, with purple and blue representing the top surface and atmospheric layer of the Shiniulan Formation, respectively; the Shiniulan Formation inversion data volume profile is shown in Figure 3, the curvature attribute volume profile is shown in Figure 4, and the ant-like attribute volume profile is shown in Figure 5. Figure 5 As shown.

[0048] S40. Adjust the transparency value for each type of data displayed. Specifically, adjust it according to the actual needs within the transparency range of 0-1.

[0049] In an embodiment of the present invention, the transparency of the two-dimensional profile is adjusted. The transparency value is set between 0 and 1, where 0 represents full transparency and 1 represents opaqueness. The smaller the value, the higher the transparency. The transparency of the original body profile is set to 1, and the values ​​of other body profiles are set according to actual needs. The transparency can be set in segments according to the value range: for example, if the data range is 10-50, and geologists consider the range of 10-30 to be favorable reservoir information, then 10-30 is set to opaque 1; the range of 30-40 is partially useful, so the transparency is set to 0.5; and the range of 40-50 is considered useless information, so it can be set to full transparency 0.

[0050] It should be noted that the color scale of each data point in the two-dimensional profile is adjusted separately, and the transparency is selectively adjusted as needed.

[0051] During the display process, any one or more types of 3D data can be turned off at any time, leaving only one or more types of data, making the operation convenient and quick.

[0052] For example, such as Figure 6 As shown in the multidimensional data overlay display profile, the data with more valid data is generally displayed at the bottom, and the data with less valid data is displayed at the top. For example, earthquake data is displayed at the bottom, and ant body data is displayed at the top. The color scale of each type of data is adjusted according to the commonly used color scale for each type of data, and the same color scale is avoided for different data as much as possible. The key to this method is to display invalid data transparently. The purpose is to turn off invalid values ​​by making them transparent, thereby revealing the valid data part and making the valid data information more intuitive.

[0053] It should be noted that this method was used in experimental research conducted in the Shiniulan Formation of the Zigong Block in southern Sichuan. Through multi-dimensional data overlay and display, effective information from multiple data types was simultaneously displayed, providing geologists with more intuitive, convenient, and rapid results for the target area. This effectively guided well placement in the Shiniulan Formation, supported the production of five high-yield wells within the Zigong Block, and provided a more accurate and reliable basis for exploration and development.

[0054] This invention organizes and inputs data by using a unified data format and assigning individual types. It displays data with more valid data at the bottom and data with less valid data at the top. The color scale for each type of data is adjusted according to its common color scale. It utilizes a key technology for transparent processing of invalid data to close invalid values ​​and expose the valid data. During the display process, any one or more types of data can be closed at any time. The goal is to simultaneously display valid information from multiple dimensions of data, providing geological personnel with more intuitive, convenient, and faster results information for the target area.

[0055] It should be understood that although the above description follows a certain order, these steps are not necessarily executed in that order. Unless otherwise expressly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, some steps in this embodiment may include multiple steps or multiple stages, which are not necessarily completed at the same time, but may be executed at different times. The execution order of these steps or stages is not necessarily sequential, but may be performed alternately or in turn with other steps or at least a portion of the steps or stages in other steps.

[0056] In one embodiment, see Figure 7 As shown, an embodiment of the present invention also provides a multi-dimensional data overlay display system, which includes a data volume input module 100, a data volume type setting module 200, a two-dimensional profile extraction module 300, and a transparency adjustment module 400.

[0057] The data input module 100 is used to acquire several types of three-dimensional data and input the three-dimensional data in a loop according to the three-dimensional data table for loop format.

[0058] In embodiments of the present invention, the three-dimensional data includes seismic volume data, inversion volume data, and ant-body data. The seismic volume data is the original volume; the inversion volume data is favorable reservoir information calculated from the seismic volume data; and the ant-body data is fault information calculated from the seismic volume data.

[0059] In embodiments of the present invention, the three-dimensional data is in a three-dimensional data format, comprising first-dimensional data, second-dimensional data, and third-dimensional data; the first-dimensional data is a line number, the second-dimensional data is a track number, and the third-dimensional data is time or depth. It should be noted that each data table is of the same size, meaning that each dimension of data has the same number of unit points, and the number and position of unit points in each three-dimensional data set are completely consistent, each reflecting different values ​​at the same point in space.

[0060] In an embodiment of the present invention, the data input module 100 is used to collect the maximum and minimum values ​​of each dimension of data, such as the maximum value of line number Lmax, the minimum value of line number Lmin, and the number of line numbers Lmax-Lmin+1; the maximum value of track number Mmax, the minimum value of track number Mmin, and the number of track numbers Mmax-Mmin+1. Assuming the third dimension of data is time, with a maximum time sampling point Tmax, a minimum time sampling point Tmin, and the number of sampling points Tmax-Tmin+1, a for loop condition is set. An integer i is created, with an initial value of 1, a step size of 1, and an ending value of LmaxLmin+1. A two-dimensional matrix is ​​formed using the line number as the X-axis, with a minimum value of 0 and a maximum value of LmaxLmin+1; and the track number as the Y-axis, with a minimum value of 0 and a maximum value of Mmax-Mmin+1. The loop steps are: assigning the i-th time value to the L(i)Lmin+1-th row and M(i)Mmin+1-th column of the two-dimensional matrix; this is repeated until the loop ends; each three-dimensional data is input according to this step.

[0061] In embodiments of the present invention, the three-dimensional data further includes input layer data. The input layer data is a data table of time or depth sampling points on lines and traces in two dimensions. Each cell in this data table contains the coordinate values ​​of the line, trace, and time / depth sampling points in three dimensions. This coordinate table constitutes a two-dimensional surface slice in the three-dimensional data volume. The input method is consistent with the data volume input.

[0062] In embodiments of the present invention, the three-dimensional data further includes curvature attribute volume data.

[0063] The data body type setting module 200 is used to set several three-dimensional data types, and each three-dimensional data type is different.

[0064] It should be noted that separate types are set for each type of 3D data, such as seismic data as A, inversion data volume as B, and ant volume as C.

[0065] It should be noted that different 3D data represent different meanings, so a different type needs to be defined for each data volume in this step; the specific type is not required. This step lays the foundation for later color adjustments, and each type of data has its own color bar.

[0066] The two-dimensional profile extraction module 300 is used to display each type of three-dimensional data after the completion type setting.

[0067] In an embodiment of the present invention, the two-dimensional profile extraction module 300 is used to slice each type of three-dimensional data and cut out a two-dimensional profile for display according to the first-dimensional data or the second-dimensional data. The original volume profile is displayed first, and other volume profiles are displayed sequentially.

[0068] The two-dimensional profile extraction module 400 is used to adjust the transparency value of each type of data displayed.

[0069] In an embodiment of the present invention, the transparency of the two-dimensional profile is adjusted. The transparency value is set between 0 and 1, where 0 represents full transparency and 1 represents opaqueness. The smaller the value, the higher the transparency. The transparency of the original body profile is set to 1, and the values ​​of other body profiles are set according to actual needs. The transparency can be set in segments according to the value range: for example, if the data range is 10-50, and geologists consider the range of 10-30 to be favorable reservoir information, then 10-30 is set to opaque 1; the range of 30-40 is partially useful, so the transparency is set to 0.5; and the range of 40-50 is considered useless information, so it can be set to full transparency 0.

[0070] It should be noted that the color scales of each data point in the 2D profile can be adjusted separately, and the transparency can be selectively adjusted as needed. During the display process, any one or more types of 3D data can be turned off at any time, leaving only one or a few data points visible, making the operation convenient and quick.
