Description

Technical Field

[0001] This invention relates to the field of seismic exploration, and more specifically, to a method, apparatus, electronic device, and medium for correcting nodal data. Background Technology

[0002] With the development of computer, communication, electronics and manufacturing technologies, geophysical exploration instruments have also entered an era of rapid development. Wired instruments and nodal instruments have developed rapidly, and various instruments have emerged one after another. In recent years, in particular, with the influence of long-term low oil prices and the continuous growth in demand for high-density large-scale data acquisition, inexpensive and efficient nodal instruments have rapidly occupied the geophysical exploration market.

[0003] Currently, mainstream processing software can only recognize single-shot gather data. Therefore, the raw gather data of a node must be organized into single-shot gather data for later processing. Taking the I-Nodal node instrument as an example, the process for generating single-shot gather records is as follows: read the raw gather data of the node, and then, according to the correspondence table between the node instrument number and the receiver number, GPS time, and SPS file, cut it into single-line gather data. After all the single-line gather data involved in a single shot are complete, merge all the single-line gather data into single-shot gather data.

[0004] Taking the I-Nodal node instrument as an example, based on continuous acquisition at a sampling rate of 1ms 24 hours a day, its data volume is approximately 500M. With an operating time of about 10 days in one acquisition cycle, the total data storage capacity of a single node instrument reaches 5000M. Assuming 20 receiver lines and 200 channels per shot for 500 shots, the total number of single-line shot gather data segments is 10,000. At a time of 0.24 minutes per segment, segmenting these single-line shot gather data segments would take 40 hours. Merging these 10,000 segments into 500-shot single-shot gather data takes approximately 0.5 hours. Therefore, the time from the node's original gather data to the final single-shot gather data is approximately 40.5 hours. As can be seen from the process, when an incorrect channel is found during the single-shot gather data check, it is necessary to re-segment the single-line shot gather data related to that channel and then execute the single-shot gather data synthesis process. This time-consuming process severely impacts the post-processing progress, leading to delays in monitoring the overall data quality and potentially affecting the completion of geological tasks.

[0005] Therefore, it is necessary to develop a method, apparatus, electronic device, and medium for correcting node data.

[0060] Preferred embodiments of the invention will now be described in more detail. While preferred embodiments of the invention are described below, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0061] This invention provides a method for correcting node data, comprising:

[0062] The process begins by identifying erroneous channels in the common shot gather and then determining the corresponding geophones. Specifically, in production, each node instrument number corresponds to a geophone number. Generally, errors in single-shot gather data occur when the correspondence between the geophone number and the node instrument number is incorrect. Therefore, after identifying erroneous channels in the common shot gather, it is necessary to further determine the corresponding geophones to locate the incorrect node instruments and ultimately determine the correct node instrument data.

[0063] Based on the detector point, determine the correct trace data; in one example, determining the correct trace data based on the detector point includes:

[0064] Based on the detector point, locate the correct nodal instrument data;

[0065] Determine the correct route data based on the GPS time of the incorrect route.

[0066] In one example, finding the correct nodal instrument data based on the receiver point includes:

[0067] By using information from field reports, construction task sheets, and node locations, the correct node instrument data corresponding to the incorrect channel at the construction time can be found.

[0068] In one example, determining the correct track based on the GPS time of the mistrack includes:

[0069] Based on the GPS time with errors, determine the data corresponding to the same GPS time in the node instrument data, which is the starting point data;

[0070] Starting from the initial data, multiple sampling points are searched backwards to form the correct trace data;

[0071] The number of sampling points for the correct channel is the same as the number of sampling points for the incorrect channel.

[0072] Specifically, by using information from field reports, construction task sheets, and node locations, the correct node instrument data corresponding to the incorrect channel at the construction time is found, which is the correct node instrument data.

[0073] Each sampling point in the node instrument data corresponds to a GPS time and a detector point number. Based on the GPS time of the erroneous channel, the data corresponding to the same GPS time in the node instrument data is determined, which is the starting data. Starting from the starting data, multiple sampling points are searched backward to form the correct channel data. Its data format is the standard SGY format, where the number of sampling points for the correct channel is the same as the number of sampling points for the erroneous channel.

[0074] Replace erroneous data with correct data to output the correct common shot point set. In one example, replacing erroneous data with correct data and outputting the correct common shot point set includes:

[0075] Based on the file information of the correct trajectory data, find the corresponding erroneous trajectory in the common shot point trajectory set;

[0076] Replace the incorrect data with the correct data and output the correct common shot point set.

[0077] In one example, the file information includes the file number, detector line number, and detector point number.

[0078] In one example, finding the corresponding erroneous path in the common shot point set includes:

[0079] Based on the file number, detector line number, and detector point number of the correct trace data, find the data location in the common shot point trace set that matches all three of the above information; this is the erroneous trace.

[0080] Specifically, a common shot gather consists of hundreds or thousands of individual data points, arranged linearly, one after another until the last one. Each individual data point has a file number, detector line number, and detector point number. We already know the file number, detector line number, and detector point number of erroneous channels. To ensure the correctness of data operations, we need to locate the erroneous channels in the common shot gather. In practice, based on the file number, detector line number, and detector point number of the correct channels, we search channel by channel in the common shot gather until we find a data point that matches all three pieces of information; this is the erroneous channel. We then replace the erroneous channel data with the correct channel data to output the correct common shot gather.

[0081] The present invention also provides an apparatus for correcting node data, comprising:

[0082] The receiver point determination module identifies erroneous channels in the common shot gather and determines the corresponding receiver points. Specifically, in production, each node instrument number corresponds to a receiver point number. Generally, errors in single-channel data in single-shot gathers occur due to a mismatch between the receiver point number and the node instrument number. Therefore, after identifying erroneous channels in the common shot gather, it is necessary to further determine the receiver points corresponding to these erroneous channels in order to subsequently locate the incorrect node instruments and ultimately determine the correct node instrument data.

[0083] The lookup module determines the correct trace data based on the detector point; in one example, determining the correct trace data based on the detector point includes:

[0084] Based on the detector point, locate the correct nodal instrument data;

[0085] Determine the correct route data based on the GPS time of the incorrect route.

[0086] In one example, finding the correct nodal instrument data based on the receiver point includes:

[0087] By using information from field reports, construction task sheets, and node locations, we can find the correct node instrument data for the incorrect channel corresponding to the detection point at the construction time.

[0088] In one example, determining the correct track based on the GPS time of the mistrack includes:

[0089] Based on the GPS time with errors, determine the data corresponding to the same GPS time in the node instrument data, which is the starting point data;

[0090] Starting from the initial data, multiple sampling points are searched backwards to form the correct trace data;

[0091] The number of sampling points for the correct channel is the same as the number of sampling points for the incorrect channel.

[0092] Specifically, by using information from field reports, construction task sheets, and node locations, the correct node instrument data corresponding to the incorrect channel at the construction time is found, which is the correct node instrument data.

[0093] Each sampling point in the node instrument data corresponds to a GPS time and a detector point number. Based on the GPS time of the erroneous channel, the data corresponding to the same GPS time in the node instrument data is determined, which is the starting data. Starting from the starting data, multiple sampling points are searched backward to form the correct channel data. Its data format is the standard SGY format, where the number of sampling points for the correct channel is the same as the number of sampling points for the erroneous channel.

[0094] The correction module replaces erroneous data with correct data and outputs the correct common shot point set. In one example, replacing erroneous data with correct data and outputting the correct common shot point set includes:

[0095] Based on the file information of the correct trajectory data, find the corresponding erroneous trajectory in the common shot point trajectory set;

[0096] Replace the incorrect data with the correct data and output the correct common shot point set.

[0097] In one example, the file information includes the file number, detector line number, and detector point number.

[0098] In one example, finding the corresponding erroneous path in the common shot point set includes:

[0099] Based on the file number, detector line number, and detector point number of the correct trace data, find the data location in the common shot point trace set that matches all three of the above information; this is the erroneous trace.

[0100] Specifically, based on the file number, detector line number, and detector point number of the correct trace data, the common shot point trace set is searched trace by trace until a data location matching all three pieces of information is found; this is the erroneous trace. The erroneous trace data is replaced with the correct trace data, and the correct common shot point trace set is output.

[0101] The present invention also provides an electronic device, comprising: a memory storing executable instructions; and a processor executing the executable instructions in the memory to implement the above-described method for correcting node data.

[0102] The present invention also provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the above-described method for correcting node data.

[0103] To facilitate understanding of the solutions and effects of the embodiments of the present invention, four specific application examples are given below. Those skilled in the art should understand that these examples are merely for the purpose of understanding the present invention, and any specific details therein are not intended to limit the present invention in any way.

[0104] Example 1

[0105] Figure 1 A flowchart illustrating the steps of a method for correcting node data according to an embodiment of the present invention is shown.

[0106] like Figure 1 As shown, the method for correcting node data includes: step 101, determining the erroneous traces in the common shot set and determining the detectors corresponding to the erroneous traces; step 102, determining the correct trace data based on the detectors; step 103, replacing the erroneous trace data with the correct trace data and outputting the correct common shot set.

[0107] Figure 2 A schematic diagram of erroneous data and waveforms is shown according to an embodiment of the present invention.

[0108] During construction, field replacement of nodal points involved manually recording the correspondence between nodal point numbers and detector point numbers. For example, the earliest deployed nodal point number for track 1518 on line 11251 was 673645. During a line inspection, this nodal point experienced low voltage and was replaced with a nodal point numbered 662057. However, due to an operational error, this change was not reported to the technical team, and the data from the nodal point's associated software was still being processed using data from the nodal point numbered 673645. Incorrect track data was also present. Figure 2 As shown, the timing of channel 1518 in the synthesized single-shot gather data of file number 16548, detector line number 11251, and detector point number is abnormal. The first arrival time is earlier than that of the surrounding channels, but this channel basically does not jump when the surrounding channels jump on their first arrival, indicating that the data of this channel is incorrect.

[0109] Figure 3a , Figure 3b The diagrams show a waveform comparison of the erroneous channel and the correct channel according to an embodiment of the present invention.

[0110] Reorganize the correct node data (number 662057) corresponding to detector line number 11251 and detector point number 1518 in file number 16548. Figure 3a The waveform containing errors in the original synthesized single-shot gathering data. Figure 3b The waveform of the correct single-channel gather data after recutting.

[0111] To obtain the correct file number, detector line number, and detector point number information for single-channel gather data, the file number is located in bytes 3609-3612, represented by fvidchan; the detector line number is located in bytes 3621-3624, represented by rlinechan; the detector point number is located in bytes 3625-3628, represented by rpointchan; and the channel data starts from byte 3841, with all subsequent bytes being channel data, represented by seismic.

[0112] To obtain the file number, detector line number, and detector point number information of the single-shot gather data with errors in a single channel, the file number is located in bytes 3609-3612 and is represented by fvidshot. The file length is represented by filelengthshot. The number of sampling points is located in bytes 3221-3222 and is represented by sampleshot. The channel data length is represented by data_lengthshot and is calculated by the formula sampleshot*4+240. The total number of channels is represented by tracecountshot and is calculated by the formula (filelengthshot-3600) / data_lengthshot.

[0113] During calibration, the file number, detector line number, and detector point number of a single channel are read first. Then, the file number of a single shot is read. The file number of the single channel and the single shot are checked for consistency. If they do not match, the next shot is read, and so on, until the file numbers match. For shots with the same file number, the header information of the k-th channel (where k is an array starting from 1 and incrementing by 1, with a maximum value equal to the total number of channels, i.e., tracecountshot) is read sequentially. The rlineshot position is 3621 + (k - 1) * data_lengthshot (4 bytes), and the rpointshot position is 3625 + (k - 1) * data_lengthshot (4 bytes). At this point, rlinechan is compared with rlineshot, and rpointchan with rpointshot. If they do not match, the next channel is read, k = k + 1, until both match simultaneously. Only then can data calibration be performed, and the current position is 3841 + (k - 1) * data_lengthshot.

[0114] Figure 4 A schematic diagram of the corrected data and waveform of the correct channel according to an embodiment of the present invention is shown.

[0115] Using seimic, replace the erroneous trajectory data in the single-shot ensemble data starting from the confirmed location. After data correction is complete, output the correct single-shot ensemble data, such as... Figure 4 As shown.

[0116] contrast Figure 2 , Figure 4 File number 16548, detector line number 11251, detector point number 1518; waveforms of the data before and after correction are visible. Figure 4 The corrected arrival times are largely consistent with those of the surrounding tracks, indicating that the corrected single-shot gathering data is accurate.

[0117] The above steps can be repeated sequentially to correct more data.

[0118] To test the effectiveness of this invention, it was put into practical application. The invention was tested in a three-dimensional environment. The project node had a single-shot data volume of 367M, a single detector line with 683 channels, and a total of 13,660 receiving channels. The testing workload involved 30 erroneous channels affecting 4,389 shots. This required re-slicing the detector lines involving these 30 channels into single-line shot gather data, and then merging the single-line shot gather data into single-shot shot gather data according to the observation system. This completed the testing workload in 81.8 hours. Using this invention, the 30 erroneous channels were first organized into correct single-channel gather data, and then the corresponding 30 channels in the original synthesized single-shot shot gather data were corrected. This process took only 11.07 hours, improving efficiency by nearly 7 times.
