Description

Technical Field

[0001] This application relates to the field of petroleum geophysical exploration data processing technology, specifically to a method, apparatus, equipment, and storage medium for efficient on-site quality control processing of node data. Background Technology

[0002] Currently, the Changqing exploration area has fully entered the era of three-dimensional node exploration, with nearly 4,000 km of exploration completed annually. 2 The Changqing Exploration Area has completed over 500,000 data acquisition missions. Therefore, the synthesis of massive amounts of node data and the quality control of node status are unavoidable realities in the current field processing. Node data needs to be downloaded and synthesized, making it impossible to guarantee 100% accuracy. Furthermore, each batch of incoming data is large, and the processes of data copying, decoding, and observation are time-consuming, posing a significant challenge to the timeliness of node data synthesis error correction and field data quality control.

[0003] In the era of wired data acquisition, on-site processing had relatively complete processing procedures and quality control standards, which enabled timely detection of problems, ensured data accuracy, and guaranteed data quality. However, for on-site processing of node data, the work of checking the accuracy of data synthesis and removing a large number of empty and waste shots has been added. At present, conventional processing and quality control procedures can no longer meet the needs of efficient acquisition, and cannot achieve fast and efficient processing and timely quality control and error correction.

[0004] The existing node data synthesis mainly suffers from the following problems: spatiotemporal data synthesis, rejection of waste artillery, loss of arrangement, loss of track, and timely quality control of node working status. All of these require efficient on-site processing to fully realize point-line-surface data quality control. However, conventional "energy attribute" extraction and abnormal track statistics processes are difficult to implement for massive amounts of big data, and are basically impossible to implement when different domain attribute statistics are involved.

[0005] Among related technologies, there are relatively mature technical processes for data processing quality control; however, there is a lack of fast and efficient processing processes for on-site processing and comprehensive quality control of node data. Summary of the Invention

The recording length of the target node synthetic seismic data is within a preset time and the number of traces is within a preset range.

[0009] For each shot's synthetic seismic data to be processed, determine whether the synthetic seismic data of the current shot's to be processed node is an empty file based on the amplitude of the sampling points in the synthetic seismic data of each shot's to be processed node, and remove empty files from the synthetic seismic data of the to be processed node.

[0010] Based on the non-working trace head attributes and multi-domain overlay profile trace head attributes, the statistical synthesis quality and node working status in the multi-domain are analyzed for the synthesized seismic data after removing empty files.

[0011] In an optional embodiment of this application, the method further includes:

[0012] The seismic data of the nodes to be processed after removing empty files are numbered according to the arrangement, and the arrangement data corresponding to each number is obtained.

[0022] The arrangement data with the current number whose root mean square sum of amplitude is less than the preset sum is considered abnormal arrangement data.

[0023] In an optional embodiment of this application, determining whether the synthetic seismic data of the current shot is an empty file based on the amplitude of the sampling points in the synthetic seismic data of each shot to be processed node includes:

[0025] The root mean square average of the amplitudes of the synthetic seismic data corresponding to each node to be processed in the current shot is summed to obtain the root mean square average sum of the amplitudes of the synthetic seismic data corresponding to each node to be processed in the current shot.

[0026] Sort the sum of the root mean square amplitudes of the synthesized seismic data of each shot node to be processed, and use the synthesized seismic data of the current shot node to be processed with a sum of the root mean square amplitudes less than the preset sum as an empty file.

[0027] In an optional embodiment of this application, the step of statistically analyzing the synthesis quality and the working status of nodes in multiple domains based on the non-working path head attributes and the multi-domain overlay profile path head attributes includes:

[0028] The channels with a maximum sample amplitude value of 0 in the data channel header attribute are designated as non-working channels.

[0029] The gun domain, detector domain, and detector line domain are each constructed using a superimposed profile method to obtain the number of inactive channels corresponding to each domain. Specifically, the profile channel in the gun domain represents each shot, and the coverage count of each channel represents the total number of channels per shot plus the number of inactive channels. The profile channel in the detector point domain represents the detector at each node in the work area, and the coverage count of each channel represents the working state of each node, i.e., the number of shots fired at each detector point. The profile channel in the detector line domain represents each arrangement of the shot, and the number of channels represents the number of arrangements in the composite shot.

[0030] The number of inactive channels corresponding to the shot domain, detector domain, and detector line domain are used as evaluation factors for the data arrangement status and the working status of nodes in multiple domains.

[0037] Compared with the prior art, the technical solutions provided in this application have at least some or all of the following advantages:

[0038] The efficient on-site quality control processing method for node data described in this application involves selecting target node synthetic seismic data for a target work area, performing maximum amplitude limitation processing on the target node synthetic seismic data to obtain the node synthetic seismic data to be processed. The recording length of the target node synthetic seismic data is within a preset time period, and the number of traces is within a preset range. For each shot's node synthetic seismic data to be processed, the method determines whether the current shot's node synthetic seismic data is an empty file based on the amplitude of the sampling points in each trace of the current shot's node synthetic seismic data, and removes empty files from the node synthetic seismic data to be processed. Based on the non-working trace head attributes and multi-domain overlay profile trace head attributes, the method statistically analyzes the synthesis quality and the working status of nodes in multiple domains.

[0048] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0049] Please see Figure 1 The node data on-site high-efficiency quality control processing method provided in this application embodiment includes the following steps 100 to 300:

[0050] Step 100: Select the target node synthetic seismic data of the target work area, and perform maximum amplitude limitation processing on the target node synthetic seismic data to obtain the node synthetic seismic data to be processed. The recording length of the target node synthetic seismic data is within the preset time and the number of traces is within the preset range.

[0051] Step 200: For each shot's synthetic seismic data to be processed, determine whether the synthetic seismic data of the current shot's to-be-processed nodes is an empty file based on the amplitude of the sampling points in the synthetic seismic data of each shot's to-be-processed nodes, and remove empty files from the synthetic seismic data of the to-be-processed nodes.

[0052] Step 300: Based on the non-working trace head attributes and multi-domain overlay profile trace head attributes, statistically analyze the synthesis quality and node working status in the multi-domain synthesized seismic data after removing empty files.

[0053] In an optional embodiment of this application, the synthetic seismic data of the target node is subjected to maximum amplitude limiting processing, including:

[0054] Set the amplitude of the target node's synthesized seismic data that exceeds the preset amplitude threshold to 0.

[0055] In an optional embodiment of this application, the method further includes:

[0056] The seismic data of the nodes to be processed after removing empty files are numbered according to the arrangement, and the arrangement data corresponding to each number is obtained.

[0057] For each specified number of arrangement data, determine whether the arrangement data of the current number is abnormal based on the amplitude of the sampling points in the arrangement data of the current number, and remove abnormal arrangement data from the synthetic seismic data of the nodes to be processed after removing empty files.

[0058] In an optional embodiment of this application, the step of numbering the synthetic seismic data of the nodes to be processed after removing empty files according to the arrangement to obtain the arrangement data corresponding to each number includes:

[0059] The seismic data of the nodes to be processed after removing empty files corresponding to each detector line are synthesized into a set of permutation data, and the number of each permutation data is determined.

[0060] In an optional embodiment of this application, the number of each group of permuted data is determined by the following expression:

[0061]

[0062] Where, num layout To number the data, sp point For detector line numbering, gp line is the number of the detector line channel, and n is the interval between the logical stub numbers.

[0063] This application addresses the issue of inaccurate line and channel numbers in variable time-varying arrangements by employing a specific calculation method to number the arrangements, reducing the amount of data calculation. It also combines "non-working channels" and "arrangement RMS energy values" to quickly eliminate problematic arrangements, resulting in more convenient and accurate results.

[0064] In an optional embodiment of this application, determining whether the currently numbered arrangement data is abnormal arrangement data based on the amplitude of the sampling points in the currently numbered arrangement data includes:

[0065] Determine the root mean square average of the amplitudes of all sample points in each data point of the currently numbered permutation;

[0066] The root mean square average of the amplitudes corresponding to the current numbered arrangement of data is summed to obtain the root mean square average sum of the amplitudes corresponding to the current numbered arrangement of data.

[0067] The arrangement data with the current number whose root mean square sum of amplitude is less than the preset sum is considered abnormal arrangement data.

[0068] In an optional embodiment of this application, step 200, determining whether the synthetic seismic data of the current shot's processing node is an empty file based on the amplitude of the sampling points in the synthetic seismic data of each processing node of the current shot, includes:

[0069] Determine the root mean square value of the amplitude of all sampling points in the synthetic seismic data of each node to be processed in the current shot;

[0070] The root mean square average of the amplitudes of the synthetic seismic data corresponding to each node to be processed in the current shot is summed to obtain the root mean square average sum of the amplitudes of the synthetic seismic data corresponding to each node to be processed in the current shot.

[0071] Sort the sum of the root mean square amplitudes of the synthesized seismic data of each shot node to be processed, and use the synthesized seismic data of the current shot node to be processed with a sum of the root mean square amplitudes less than the preset sum as an empty file.

[0072] In an optional embodiment of this application, the root mean square average amplitude of all sampling points in the synthetic seismic data of each node to be processed in the current shot is determined by the following expression:

[0073]

[0074] Where RMS is the root mean square value of the amplitude of all sampling points in the synthetic seismic data of each node to be processed in the current shot, x1, x2, ... x n , where n represents the amplitude value of each sampling point in the synthetic seismic data of each node to be processed, and n is the number of sampling points.

[0075] In an optional embodiment of this application, the root mean square average amplitude of the synthesized seismic data corresponding to each node to be processed in the current shot is summed using the following expression:

[0076]

[0077] Among them, R sum This represents the root mean square sum of the amplitudes corresponding to the synthesized seismic data of the current shot node to be processed. These are the RMS values ​​for each course.

[0078] This application eliminates empty and invalid shots by limiting amplitude, time, and number of channels. Since empty and invalid shots differ from valid shots in time and space, the energy is increased by accumulating RMS values ​​to improve the accuracy and efficiency of identifying empty and invalid shots. This effectively solves the problem of a large number of empty and invalid shots during high-efficiency excitation. Compared with related technologies, it has higher accuracy and shorter time in eliminating empty and invalid shots. In addition, by limiting the maximum amplitude of the sample points and selecting a channel set within a certain time period and channel number range, data stability is maintained and the energy difference between valid shots and empty and invalid shots is increased.

[0079] In an optional embodiment of this application, step 300, which involves calculating the statistical synthesis quality and the working status of nodes in multiple domains based on the non-working path head attributes and the multi-domain overlay profile path head attributes, includes:

[0080] The channels with a maximum sample amplitude value of 0 in the data channel header attribute are designated as non-working channels.

[0081] The gun domain, detector domain, and detector line domain are each constructed using a superimposed profile method to obtain the number of inactive channels corresponding to each domain. Specifically, the profile channel in the gun domain represents each shot, and the coverage count of each channel represents the total number of channels per shot plus the number of inactive channels. The profile channel in the detector point domain represents the detector at each node in the work area, and the coverage count of each channel represents the working state of each node, i.e., the number of shots fired at each detector point. The profile channel in the detector line domain represents each arrangement of the shot, and the number of channels represents the number of arrangements in the composite shot.

[0082] The number of inactive channels corresponding to the shot domain, detector domain, and detector line domain are used as evaluation factors for the data arrangement status and the working status of nodes in multiple domains.

[0083] In this application, to address situations where traces are missing, arrangements are missing, or only partial arrangements are synthesized during data synthesis, the method determines whether a current trace is inactive by checking if the trace header attribute "maximum sample point amplitude value per trace" is 0. Secondly, the number of inactive traces is obtained by unfolding the data in multiple domains (i.e., shot domain, receiver domain, and receiver line domain) using a "stacked profile" method. The fold attribute value of the profile represents the total number of inactive traces. This method allows for the rapid collection of data on arrangement status and node operational status across multiple domains, significantly reducing the workload in the field.

[0084] Faced with massive amounts of 3D node data, this application efficiently completes tasks such as removing empty and abandoned shells, data synthesis and inspection, and node status quality control, forming a set of efficient processing procedures for field processing of node data, providing a relatively complete and convenient quality control method for the era of 3D nodes.

[0085] In an optional embodiment of this application, see [link to relevant documentation]. Figure 2 Taking the loess hilly terrain in the field as an example, the efficient on-site quality control processing method for node data in this application includes the following steps:

[0086] T1 uses a "limited amplitude, limited time, limited number of channels" approach to increase energy difference and eliminate empty and invalid files. Specifically, to address the issue of numerous empty and invalid files in the excitation system during high-efficiency acquisition, this approach sets the maximum sample point amplitude value in the work area to 0.6, the time interval to 0-1000ms, and the number of channels to be limited to the near offset range of 0-1000m, maximizing energy difference. Furthermore, it analyzes the RMS value of each shot through shot gather attributes and sums the calculated RMS values ​​to further amplify energy difference. The RMS values ​​are then sorted according to their magnitude. Based on past experience in the Loess Plateau region, RMS values ​​less than 0.1 are considered empty and invalid files, and the remaining files are considered valid shots. Figure 3As shown.

[0087] T2 utilizes the method of checking if the "maximum amplitude value per sample point" attribute at the track head is zero to eliminate non-working tracks. It also performs "profile overlay" across multiple domains to check the coverage count and track head attribute, obtaining the total number of non-working tracks and reducing fieldwork. Specifically, the data collection project used in this loess mountain area employs a 44L4S224R 3D observation system. First, it checks if the "maximum amplitude value per sample point" attribute at the track head is zero to eliminate non-working tracks. Second, it divides the data into two types: all data and data after eliminating non-working tracks. The data length only needs to be 12ms. This further... This reduces the amount of data computation; when the overlay flag is set to "Shot Domain," the profile track represents each shot, and the "coverage count" of each track is the total number of tracks and the number of inactive tracks per shot; when the overlay flag is set to "Detector Point Domain," the profile track represents the detector at each node in the work area, and the "coverage count" of each track is the working status of each node, indicating how many shots each detector point has worked; when the overlay flag is set to "Detector Line," the profile track represents each arrangement of this shot, and the number of tracks indicates how many arrangements are synthesized for this shot, truly achieving efficient, multi-domain quality control, such as... Figure 4 As shown.

[0088] T3 uses a formula to number the permutations, enabling specific extraction of permutation numbers and reducing data volume. Specifically, it assigns labels to the three-dimensional permutations according to the numbering method mentioned earlier, where n = 8, meaning the logical station interval is 8. For example... Figure 5 As shown, permutation extraction and analysis are now more convenient (previously, line numbers and channel numbers were inaccurate when viewed differently); for extracted far permutations, a combination of "energy statistics" and "inactive channel rate" is used for filtering, quickly identifying problematic permutations, such as... Figure 5 , Figure 6 As shown.

[0089] This application enables efficient processing of massive 3D node data, further enhances on-site processing technology support, shortens the cycle of node data synthesis and node working status quality control, improves the efficiency and accuracy of acquired data, and helps improve the quality and efficiency of seismic acquisition construction. It aims to achieve the goal of rapid and effective preprocessing of massive node-synthesized data.

The method according to claim 1, characterized in that, The process of statistically analyzing the quality of data synthesis and the working status of nodes in multiple domains based on the non-working track head attributes and the track head attributes of the multi-domain overlay profile includes: The channels with a maximum sample amplitude value of 0 in the data channel header attribute are designated as non-working channels. The gun domain, detector domain, and detector line domain are each constructed using a superimposed profile method to obtain the number of inactive channels corresponding to each domain. Specifically, the profile channel in the gun domain represents each shot, and the coverage count of each channel represents the total number of channels per shot plus the number of inactive channels. The profile channel in the detector point domain represents the detector at each node in the work area, and the coverage count of each channel represents the working state of each node, i.e., the number of shots fired at each detector point. The profile channel in the detector line domain represents each arrangement of the shot, and the number of channels represents the number of arrangements in the composite shot. The number of inactive channels corresponding to the shot domain, detector domain, and detector line domain are used as evaluation factors for the data arrangement status and the working status of nodes in multiple domains.

8. A high-efficiency on-site quality control and processing device for node data, characterized in that, include: The extraction module is used to select target node synthetic seismic data of the target work area, perform maximum amplitude limitation processing on the target node synthetic seismic data, and obtain the node synthetic seismic data to be processed. The recording length of the target node synthetic seismic data is within a preset time and the number of traces is within a preset range. The determination module is used to determine whether the synthetic seismic data of each shot node to be processed is an empty file based on the amplitude of the sampling points in the synthetic seismic data of each shot node to be processed, and to remove empty files in the synthetic seismic data of the shot node. The statistics module is used to statistically analyze the composite seismic data after removing empty files, based on the non-working trace head attributes and the multi-domain overlay profile trace head attributes, to determine the composite quality and the working status of nodes in multiple domains.
