Description

Technical Field

[0001] The present invention relates to the field of seismic exploration data visualization, and more specifically, to a method, device, electronic equipment and medium for drawing and displaying a seismic trace head attribute map. Background Art

[0002] The two-dimensional plane display of seismic trace header attributes is an important part of seismic data processing. It can help users understand the acquisition and processing effects of seismic data more intuitively. In the two-dimensional plane diagram, the trace header attributes of each seismic trace data are presented in the form of bar blocks of different colors. Users can understand the changes of different seismic trace header attributes in two-dimensional space, or the relationship between attributes and other attributes by comparing blocks of different colors. As seismic exploration has entered the era of big data, the amount of seismic data has increased rapidly, which has brought challenges to the two-dimensional plane display of seismic trace header attributes. In the scenario of small data volume, the trace header data can be serially read and then all the read data can be plotted to generate a two-dimensional plane attribute map. In the scenario of large data volume, the efficiency of reading and plotting seismic trace header attribute data is extremely high. Inefficient reading and plotting will bring a very bad user experience, and too long waiting time will make users lose confidence in using the software.

[0003] At present, a method for drawing and displaying seismic trace head attribute maps needs to be developed.

[0037] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0038] To facilitate understanding of the solutions and effects of the embodiments of the present invention, six specific application examples are given below. Those skilled in the art should understand that the examples are only for facilitating understanding of the present invention, and any specific details thereof are not intended to limit the present invention in any way.

[0039] Example 1

[0040] Figure 1 A flow chart showing the steps of a method for drawing and displaying a seismic trace header attribute map according to an embodiment of the present invention.

[0041] like Figure 1 As shown, the method for drawing and displaying the seismic trace head attribute map includes:

[0042] Step 101, obtaining the total number of seismic data traces and a trace header attribute list, and determining the seismic trace header attributes to be displayed;

[0043] Step 102, according to the total number of seismic data channels and the number of CPU threads of the computing node, a corresponding calculation relationship between the computing node and the seismic channel is created to perform seismic channel calculation;

[0044] Step 103, drawing a header attribute map according to the data in the map container.

[0045] In an example, the corresponding calculation relationship between the calculation node and the seismic channel is created:

[0046] According to the number of CPU threads of the computing node, the total number of seismic data channels is evenly divided into a corresponding number of data blocks and allocated to the corresponding threads.

[0047] In one example, performing seismic trace calculations includes:

[0048] The reading range of the seismic trace is set for the corresponding thread of the computing node, and each thread reads the corresponding seismic trace header attribute data in parallel for calculation.

[0049] In one example, drawing a header attribute map according to data in a map container includes:

[0050] The seismic trace header attribute data is projected onto the drawing area, and the data projected onto the drawing area is filtered through the map container to ensure that there is only one drawing data at each pixel.

[0051] Figure 2A schematic diagram showing multi-threaded reading of trace header attribute data according to an embodiment of the present invention is shown.

[0052] Specifically, to display the seismic trace header attributes, it is first necessary to read specific attribute data from the seismic trace header. The time consumption of the trace header attribute reading process will greatly increase with the increase of data volume. In order to shorten this time consumption, the present invention designs a method for reading trace header attribute data based on multi-threading, such as Figure 2 As shown in the figure. According to the number of CPU threads of the computing node, the total number of seismic data is evenly divided into a corresponding number of data blocks. Using multi-threaded parallel reading, the time consumption can theoretically be shortened to one nth of the original time consumption, where n represents the number of threads. However, the performance of multi-threading is related to the specific use environment. It has been verified in actual operation that it can indeed significantly reduce the time consumption.

[0053] After the seismic header attribute data is prepared, drawing can begin. If all the read data are drawn, it will take a long time. In order to shorten the drawing time, the present invention designs a pixel scanning drawing method. Since the distribution of the seismic header attribute data is relatively scattered in the actual spatial position, when drawing, the actual position needs to be projected into a drawing area of ​​a certain size. When the amount of data is large, multiple data points will be repeatedly drawn on each pixel point in the drawing area, resulting in a waste of drawing resources. The pixel scanning drawing method scans all data points before drawing to ensure that each pixel point has only one drawing data, and then draws. This can greatly shorten the drawing time, and can also reduce the jamming caused by drawing when scaling the drawn image or moving the display area.

[0054] Example 2

[0055] The present invention also provides a seismic trace head attribute map drawing and display device, comprising:

[0056] The seismic data acquisition module obtains the total number of seismic data traces and the trace header attribute list, and determines the seismic trace header attributes that need to be displayed;

[0057] The seismic channel calculation module creates a corresponding calculation relationship between the computing node and the seismic channel to perform seismic channel calculation according to the total number of seismic data channels and the number of CPU threads of the computing node;

[0058] The drawing module draws the header attribute map according to the data in the map container.

[0059] In an example, the corresponding calculation relationship between the calculation node and the seismic channel is created:

[0060] According to the number of CPU threads of the computing node, the total number of seismic data channels is evenly divided into a corresponding number of data blocks and allocated to the corresponding threads.

[0061] In one example, performing seismic trace calculations includes:

[0062] The reading range of the seismic trace is set for the corresponding thread of the computing node, and each thread reads the corresponding seismic trace header attribute data in parallel for calculation.

[0063] In one example, drawing a header attribute map according to data in a map container includes:

[0064] The seismic trace header attribute data is projected onto the drawing area, and the data projected onto the drawing area is filtered through the map container to ensure that there is only one drawing data at each pixel.

[0065] Specifically, to display the attributes of the seismic trace header, it is necessary to first read specific attribute data from the seismic trace header. The time consumption of the trace header attribute reading process will increase greatly with the increase of data volume. In order to shorten this part of the time consumption, Figure 2 As shown in the figure, according to the number of CPU threads of the computing node, the total number of seismic data channels is evenly divided into a corresponding number of data blocks. Multi-threaded parallel reading is used. In theory, the time consumption can be shortened to one nth of the original time consumption, where n represents the number of threads. However, the performance of multi-threading is related to the specific usage environment. It has been verified in actual operation that it can indeed significantly reduce the time consumption.

[0066] After the seismic trace header attribute data is prepared, drawing can begin. If all the read data are drawn, it will take a long time. In order to shorten the drawing time, pixel scanning drawing is performed. Since the distribution of seismic trace header attribute data is relatively scattered in the actual spatial position, when drawing, the actual position needs to be projected into a drawing area of ​​a certain size. When the amount of data is large, multiple data points will be repeatedly drawn on each pixel point in the drawing area, resulting in a waste of drawing resources. The pixel scanning drawing method is to scan all data points before drawing to ensure that each pixel point has only one drawing data, and then draw. This can greatly shorten the drawing time, and can also reduce the jamming caused by drawing when scaling the drawn image or moving the display area.

[0067] Example 3

[0068] Scan the seismic data, obtain the total number of seismic data channels and the list of channel header attributes, and determine the seismic channel header attributes that need to be displayed; obtain the number of CPU threads in the computing node, create a corresponding number of threads, set the seismic channel reading range for the corresponding threads according to the total number of seismic data channels, and each thread reads the corresponding seismic channel header attribute data in parallel; project the seismic channel header attribute data onto the drawing area, and use the map container to filter the data projected onto the drawing area to ensure that there is only one drawing data at each pixel; draw the channel header attribute map according to the data in the map container.

[0069] The present invention realizes a display scheme for large amounts of seismic trace header attribute data, accelerates the reading of seismic trace header attribute data through multi-threading, accelerates the drawing process through a pixel scanning drawing method, optimizes the interactive operation experience of the trace header attribute plane map, and improves the interactive convenience of the software.
