Description

Technical Field

[0001] The present invention relates to the technical field of geophysical exploration data processing, and in particular to a cross-hole seismic CT data batch preprocessing method and system. Background Art

[0002] The cross-hole seismic CT method has achieved remarkable results in the field of karst exploration. In the project survey, the data collected in the field are 24 or 48 seismic wave data corresponding to a single shot, and the data format is *.dat. The data file numbers of each arrangement in each hole pair are arranged from deep to shallow in order from small to large. Therefore, before data processing, these data need to be pre-processed. First, the 24 data corresponding to each shot should be manually adjusted so that their gains are roughly the same. Secondly, the data format should be converted from *.dat to *.sg2 or *.sgy, and then the data corresponding to each arrangement should be arranged in sequence so that the order of the data file numbers is reversed and arranged from deep to shallow in order from large to small. The preprocessing of these data is often a tedious and repetitive process that requires manual processing. The process is time-consuming and error-prone, affecting efficiency. Summary of the invention

[0039] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0040] The first embodiment of the present invention provides a batch preprocessing method for cross-hole seismic CT data. Figure 1 and Figure 2 Provide detailed explanation.

[0041] like Figure 1 As shown, in step S100, the cross-hole seismic CT raw data file storage path input by the user is obtained, and the cross-hole seismic CT raw data file is read based on the file storage path.

[0042] In this embodiment, only the file location directory needs to be manually input, and the remaining steps can be completed automatically.

[0043] Assume the path is:

[0044] path=r"D:\ShenHu i\DL\RSHZ-TDL-YR-BB13-RSHZ3-TDL-YR-BB22"

[0045] Using the os.li std ir() function, "files = os.li std ir(path)", the program can automatically read all data files at the file location.

[0046] like Figure 1 As shown, in step S200, the file name identification information of each cross-hole seismic CT raw data file is identified, and the cross-hole seismic CT raw data files are arranged and divided according to the identified file name identification information, and a folder corresponding to each arrangement is created.

[0047] Since the cross-hole seismic CT raw data files are named with digital numbers, in practical applications, the acquired data will be named in different ways according to different arrangements, specifically: starting with 1 or 2, such as 1001, 1002, ….

[0048] In this embodiment, data files with numbers in the range of [0,2000) are divided into the first arrangement and a first folder (named "1" folder) is created, data files with numbers in the range of [2000,3000) are divided into the second arrangement and a second folder (named "2" folder) is created, data files with numbers in the range of [3000,4000) are divided into the third arrangement and a third folder (named "3" folder) is created, and so on.

[0049] like Figure 1 As shown, in step S300, each arranged cross-hole seismic CT raw data file is converted into a format.

[0050] In this embodiment, when format conversion is performed on each *.dat data file, the original data file is first decoded to identify the data content, and then re-encoded into data in *.sgy data format according to a certain format, thereby completing the data format conversion.

[0051] like Figure 1 As shown, in step S400, each arranged cross-hole seismic CT data file that has undergone format conversion is sequenced and stored in a folder corresponding to the arrangement.

[0052] Rearrange the data file name for each arrangement, and use the read data file name to reorder it through the max and min functions:

[0053] fname=max(name[0])-i nt(fi l ename)+min(name[0]);

[0054] And output the sequenced data files to the corresponding folder.

[0055] Assuming that the original data files are named 1001 to 1020, the purpose of reordering is to change the original 1001 to 1020, and the original 1020 to 1001. If you want to reorder the file name 1002, the formula is 1020+1001-1002=1019.

[0056] The method of the present invention was applied in a karst exploration project of an intercity railway, and more than 1,600 pairs of data were preprocessed, which greatly improved the efficiency of data processing, saved internal costs, and ensured the accuracy of data preprocessing.

[0057] The specific process is as follows:

[0058] The original CT data files of a certain hole include 57 data files, 1001.dat~1034.dat and 2001.dat~2023.dat, such as Figure 3As shown. First import the folder path:

[0059] "D:\20230403\YR-BB1-DY-46-1"

[0060] Then run the program to get the corresponding two subfolders 1 and 2, corresponding to the two arrangements respectively. The folders contain the *.sgy data files that have completed data format conversion and sequencing, such as Figure 4 As shown, the processing process only takes 4 to 10 seconds, greatly improving efficiency.

[0061] A cross-hole seismic CT data batch preprocessing method provided by an embodiment of the present invention obtains a cross-hole seismic CT raw data file storage path input by a user, reads the cross-hole seismic CT raw data file based on the file storage path; identifies the file name identification information of each cross-hole seismic CT raw data file, arranges and divides the cross-hole seismic CT raw data file according to the identified file name identification information and creates a folder corresponding to each arrangement; performs format conversion on each arrangement of the cross-hole seismic CT raw data file; performs sequence processing on each arrangement of the cross-hole seismic CT data file after format conversion, and stores it in the folder of the corresponding arrangement. The present invention can quickly and accurately perform batch preprocessing on a large number of cross-hole seismic CT raw data, which not only saves time, but also avoids manual operation, ensuring the accuracy of data preprocessing.
