Description

Technical Field

[0001] The present invention belongs to the field of geophysical exploration technology, and in particular relates to a method and device for quality control of segmentation of continuous data of node seismic acquisition. Background Art

[0002] With the advancement of seismic exploration instrumentation, the size of seismic field equipment continues to shrink, and new technologies such as GPS reception, data storage, batteries, and radio frequency communication are constantly being updated. This has driven the rapid development of node-based seismic data acquisition systems. The application of node-based seismic data acquisition systems has transformed the operation of traditional wired instruments, greatly simplifying the structure of seismic data acquisition systems and making field operations faster, more flexible, and more convenient. Their key advantages include: first, they enable unlimited channel acquisition, enabling the application of ultra-high-density, wide-azimuth seismic acquisition technology; second, they allow for flexible deployment of field observation systems, allowing for flexible changes in viewing angles and receiver offsets to accommodate terrain, obstacles, and other factors, facilitating field operations and minimizing environmental impact; third, they significantly reduce the number of auxiliary field equipment, significantly reducing the amount of field equipment needed, saving both transportation costs and carbon emissions; fourth, they significantly reduce the number of field personnel required to deploy and deploy, reducing both the number of field personnel and the intensity of field work; fifth, they significantly reduce waiting time during blasting and enable continuous aliasing excitation, significantly improving operation efficiency—advantages unmatched by wired acquisition systems.

[0003] A node-based seismic data acquisition system typically consists of a node unit, a quality control unit (a handheld device or drone), a charging and downloading cabinet, and a data download and synthesis server. Node units are typically deployed in the field and, once powered on, operate autonomously, continuously acquiring data and storing it locally. After a certain period (days), the node-based data is retrieved and downloaded to the charging and downloading cabinet. Pre-configured segmentation and synthesis software is then used to segment and synthesize the continuous data collected by the node to produce a common receiver or shot gather. Summary of the Invention

[0004] The inventors discovered that the existing process for segmenting and synthesizing continuous data from node-based seismic acquisition uses segmentation software provided by node instruments produced by different manufacturers. This process lacks quality control, leading to issues with segmentation accuracy. Therefore, the present invention proposes a method and device for quality control of segmentation of continuous data from node-based seismic acquisition to ensure the accuracy of the segmented data, thereby guaranteeing the correctness of the collected seismic data.

[0005] Specifically, the node seismic acquisition continuous data segmentation quality control method proposed in the present invention is used to determine whether the input node acquisition continuous data segmentation is accurate, including the following steps:

[0006] Downloading data stored in the node to obtain the time of seismic acquisition and excitation, wherein the data stored in the node at least includes daily inspection data, log files, and seismic data;

[0007] According to the seismic acquisition excitation time and the downloaded log file, confirm whether the seismic acquisition excitation time and the node receiving time are synchronized. If they are synchronized, proceed to the next step;

[0008] Determine the excitation source type during seismic acquisition, and check whether the data content corresponding to the excitation source meets the requirements according to the preset rules. If so, proceed to the next step;

[0009] Select the daily inspection data of any node and check whether there is GPS drift. If there is drift, it is determined that the splitting condition is not met, otherwise proceed to the next step;

[0010] Checking the seismic trace header of the seismic data; if the preset parameter information is missing, determining that the segmentation condition is not met, otherwise proceeding to the next step;

[0011] The common receiving point gathers formed by segmenting the input node continuous data are obtained according to preset rules to obtain the gathers processed by linear dynamic correction. The gathers processed by linear dynamic correction are superimposed. If a superimposed data has multiple strong phases, it is judged that there is a problem with the segmentation.

[0012] Furthermore, the type of excitation source during seismic acquisition excitation is determined, and the data content corresponding to the excitation source is checked according to preset rules to see whether it meets the requirements, including:

[0013] If vibrator excitation is used for seismic acquisition, check whether the vibrator scanning signal is correct.

[0014] Furthermore, if vibroseis excitation is used for seismic acquisition, the correctness of the vibroseis scanning signal is checked, including:

[0015] Check the time length information of the true reference scanning signal generated by the controllable source excitation, and judge that the scanning signal is correct if it meets the preset threshold.

[0016] Furthermore, the type of excitation source during seismic acquisition excitation is determined, and the data content corresponding to the excitation source is checked according to preset rules to see whether it meets the requirements, including:

[0017] If explosive sources and vibrators are used simultaneously for seismic acquisition, for the same node, check whether the well-gun common receiving point gather data and the vibrator common receiving point gather data are recorded respectively. If both types of data are not recorded, it is determined that the segmentation conditions are not met.

[0018] Furthermore, the method further includes determining the type of excitation source during seismic acquisition excitation and checking whether the data content corresponding to the excitation source meets the requirements according to preset rules.

[0019] If both explosive sources and controllable vibrators are used for seismic acquisition excitation, it is also determined whether the excitation point code is recorded to distinguish the excitation source type. If not, it is determined that the segmentation condition is not met.

[0020] Furthermore, the preset parameter information includes at least: line number, point number, position coordinates, and acquisition parameters.

[0021] Furthermore, the common receiving point gathers formed by segmenting the continuous data collected by the input nodes are obtained according to the preset rules to obtain the gathers processed by linear dynamic correction. The gathers processed by linear dynamic correction are superimposed. If a superimposed data line contains multiple strong phases, it is determined that there is a problem with the segmentation, including:

[0022] The common receiving point gathers formed by segmenting the continuous data collected by the input nodes are processed. By giving a velocity, linear dynamic correction is performed on the data within a preset offset range to obtain a linear dynamic correction gather. The linear dynamic correction gathers are superimposed. If multiple positions with amplitudes reaching the preset amplitude threshold appear after superposition, it is determined that there is a problem with the segmentation.

[0023] On the other hand, the present invention also proposes a node seismic acquisition continuous data segmentation quality control device, which is used to determine whether the input node acquisition continuous data segmentation is accurate, including a data acquisition module, a synchronization judgment module, an excitation source judgment module, a drift judgment module, and a seismic trace head detection module, wherein:

[0024] The data acquisition module is used to download the data stored in the node and obtain the time of seismic acquisition and excitation. The data stored in the node at least includes daily inspection data, log files, and seismic data;

[0025] The synchronization judgment module is used to confirm whether the seismic acquisition excitation time and the node receiving time are synchronized according to the seismic acquisition excitation time and the downloaded log file, and if they are synchronized, enter the excitation source judgment module;

[0026] The excitation source judgment module is used to judge the excitation source type during seismic acquisition excitation, and check whether the data content corresponding to the excitation source meets the requirements according to preset rules. If so, it enters the drift judgment module;

[0027] The drift judgment module is used to select the daily inspection data of any node and check whether there is GPS drift. If there is drift, it is determined that the segmentation condition is not met, otherwise it enters the seismic trace head detection module;

[0028] The seismic trace header detection module is used to check the seismic trace header of the seismic data. If the preset parameter information is missing, it is determined that the segmentation condition is not met. Otherwise, the process enters the phase judgment module.

[0029] The phase judgment module is used to divide the common receiving point data formed by the continuous data collection of the input node, obtain the data set processed by linear dynamic correction according to the preset rules, and superimpose the data set processed by linear dynamic correction. If a superimposed data has multiple strong phases, it is determined that there is a problem with the segmentation.

[0030] In a third aspect, an embodiment of the present invention further discloses a computer device, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the aforementioned node seismic acquisition continuous data segmentation quality control method.

[0031] In a fourth aspect, based on the same inventive concept, an embodiment of the present invention further provides a computer-readable storage medium, which stores the aforementioned node seismic acquisition continuous data segmentation quality control method.

[0032] Based on the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0033] The present invention performs quality control inspection on the segmentation of node seismic acquisition continuous data from multiple angles, such as judging whether the seismic acquisition excitation time and the node reception time are synchronized, whether the excitation source type and excitation content during seismic acquisition excitation meet the requirements, whether there is GPS drift in the daily inspection data of the node, whether the seismic trace header of the seismic data lacks preset parameter information, and whether there are multiple strong phases in the superposition of the trace set processed by linear dynamic correction, so as to ensure the accuracy of the node segmentation data and thus ensure the correctness of the collected seismic data.

[0039] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0040] Example 1

[0041] A node seismic acquisition continuous data segmentation quality control method is used to determine whether the input node acquisition continuous data segmentation is accurate. Figure 1 As shown, it includes steps S110-S160, specifically:

[0042] Step S110, downloading the data stored in the node to obtain the time of seismic acquisition excitation, the data stored in the node at least including daily inspection data, log files, and seismic data.

[0043] In practical applications, a node seismic data acquisition system is generally composed of a node unit, a quality control unit (a handheld device or a drone), a charging and downloading integrated cabinet, and a data download and synthesis server. The node unit is usually deployed in the field and can work autonomously after being turned on, continuously collect data, and store data on-site. After a certain period (days), the node collected data is recovered and downloaded from the charging and downloading integrated cabinet. The continuous data collected by the node seismic data is then segmented and synthesized using the preset segmentation and synthesis software to obtain a common receiving point gather (such as Figure 2 shown).

[0044] This step requires downloading the data stored in the node unit, including daily inspection data, log files, and seismic data. Then, the GPS excitation time is obtained through construction information, and then segmented to form a common receiving point gather.

[0045] Step S120: confirm whether the seismic acquisition excitation time and the node receiving time are synchronized according to the seismic acquisition excitation time and the downloaded log file. If they are synchronized, proceed to the next step.

[0046] During seismic acquisition, the excitation system records an excitation time when it is excited, and the node unit also records a time when it collects data (recorded in the log file). The time synchronization between the two generally needs to be accurate to the microsecond level. If they are not synchronized, they need to be re-excited.

[0047] Step S130, determining the type of excitation source during seismic acquisition excitation, and checking whether the data content corresponding to the excitation source meets the requirements according to preset rules, and if so, executing the next step.

[0048] In some embodiments, if vibroseis excitation is used for seismic acquisition, the accuracy of the vibroseis sweep signal is checked. During field seismic acquisition, when vibroseis excitation is used, the vibroseis generates a true reference sweep signal. The accuracy of the sweep signal is determined by checking information such as the duration of the true reference sweep signal.

[0049] In other embodiments, seismic acquisition and excitation utilize two source systems (both explosive and vibroseis). Node unit records will simultaneously obtain common receiver gather data from the explosive source and from the vibroseis. Therefore, for the same node, it is possible to check whether both the well-and-gun common receiver gather data and the vibroseis common receiver gather data are recorded. If so, the subsequent segmentation and synthesis process can be guaranteed. If not, it indicates that the data recording is incorrect and the conditions for segmentation and synthesis are not met.

[0050] In addition, when using explosive sources for excitation, a mark is added to indicate that this is the case. When using controlled vibrator excitation, a mark is also added to indicate that this is the case. These two marks are called point codes. Therefore, the excitation source type can also be distinguished by determining whether the excitation point code is recorded. If the point code is not recorded, it is determined that the segmentation condition is not met.

[0051] In other embodiments, if two types of source systems are used for seismic acquisition excitation, it is possible to first check whether the well-gun common receiving point gather data and the controllable vibroseis common receiving point gather data are recorded respectively. If so, it is then determined whether the excitation point code is recorded to distinguish the excitation source type.

[0052] Step S140: Select the daily inspection data of any node and check whether there is GPS drift. If there is drift, it is determined that the splitting condition is not met, otherwise, the next step is executed.

[0053] Checking GPS time drift is to check the node clock synchronization error. If the error exceeds the preset time threshold, such as 250μs, the obtained seismic data is unqualified. Therefore, if GPS drift exists, it is judged that the segmentation condition is not met.

[0054] Step S150: Check the seismic trace header of the seismic data. If the preset parameter information is missing, it is determined that the segmentation condition is not met. Otherwise, the next step is executed.

[0055] The seismic trace header of the collected node continuous data is checked to see whether it contains information such as line number, point number, position coordinates, and collection parameters. If it contains this information, the conditions for node collection data segmentation and synthesis are met; if it does not contain this information, the conditions for node collection data segmentation and synthesis are not met.

[0056] Step S160: The common receiving point gathers formed by segmenting the input node continuous data are obtained according to preset rules to obtain the gathers processed by linear dynamic correction. The gathers processed by linear dynamic correction are superimposed. If a superimposed data has multiple strong phases, it is determined that there is a problem with the segmentation.

[0057] Specifically, the node continuous data segmentation process is to segment all the data recorded by the node in the field (for example, 24 hours), for example, into many 8s (0-8s, 26-24s, etc.), and the starting time of the segmentation is determined according to the time of stimulation.

[0058] After the node continuous data is segmented, the data of multiple nodes are rearranged to form a common receiving point gather. The offset distance of each node is fixed (such as 200, 300, 1000 meters, etc.). Given a velocity, the data of a certain range of offset distances (such as 1000-2000 meters) are selected for linear dynamic correction processing. After processing, the linear dynamic correction processed gather is obtained. The linear dynamic correction processed gather is stacked (for example, the process of stacking 5 seismic traces to obtain 1 seismic trace, such as Figure 3 If there are multiple strong phases after superposition, with large amplitudes, it means there is a problem with the segmentation.

[0059] The present invention performs quality control inspection on the segmentation of node seismic acquisition continuous data from multiple angles, such as judging whether the seismic acquisition excitation time and the node reception time are synchronized, whether the excitation source type and excitation content during seismic acquisition excitation meet the requirements, whether there is GPS drift in the daily inspection data of the node, whether the seismic trace header of the seismic data lacks preset parameter information, and whether there are multiple strong phases in the superposition of the trace set processed by linear dynamic correction, so as to ensure the accuracy of the node segmentation data and thus ensure the correctness of the collected seismic data.

[0060] Example 2

[0061] The present invention also proposes a node seismic acquisition continuous data segmentation quality control device for determining whether the input node acquisition continuous data segmentation is accurate, comprising a data acquisition module 10, a synchronization determination module 20, an excitation source determination module 30, a drift determination module 40, a seismic trace head detection module 50, and a phase determination module 60, wherein:

[0062] The data acquisition module 10 is used to download the data stored in the node and obtain the time of seismic acquisition excitation. The data stored in the node at least includes daily inspection data, log files, and seismic data.

[0063] This module needs to download the data stored in the node unit, including daily inspection data, log files, and seismic data. Then, the GPS excitation time is obtained through construction information, and then divided into common receiving point gathers.

[0064] The synchronization judgment module 20 is used to confirm whether the seismic acquisition excitation time and the node receiving time are synchronized according to the seismic acquisition excitation time and the downloaded log file. If they are synchronized, the module enters the excitation source judgment module.

[0065] During seismic acquisition, the excitation system records an excitation time when it is excited, and the node unit also records a time when it collects data (recorded in the log file). The time synchronization between the two generally needs to be accurate to the microsecond level. If they are not synchronized, they need to be re-excited.

[0066] The excitation source judgment module 30 is used to judge the excitation source type during seismic acquisition excitation, and check whether the data content corresponding to the excitation source meets the requirements according to preset rules. If so, it enters the drift judgment module.

[0067] In practical applications, if the excitation source determination module 30 determines that vibroseis excitation is used for seismic acquisition, the excitation source determination module 30 is further configured to check the accuracy of the vibroseis sweep signal. During field seismic acquisition, when vibroseis excitation is used, the vibroseis generates a true reference sweep signal. The accuracy of the sweep signal is determined by checking information such as the duration of the true reference sweep signal.

[0068] If the excitation source judgment module 30 determines that two seismic source systems are used for seismic acquisition excitation (explosive source and controllable seismic source are used at the same time), the excitation source judgment module 30 is also used to check whether the well-gun common receiving point data set and the controllable seismic source common receiving point data set are recorded for the same node respectively. If there is a record, the subsequent segmentation and synthesis process can be guaranteed. If there is no record, it means that the data record is incorrect and the conditions for segmentation and synthesis are not met.

[0069] If the excitation source judgment module 30 determines that two seismic source systems are used for seismic acquisition excitation (explosive source and controllable seismic source are used at the same time), the excitation source judgment module 30 is also used to determine whether there is a corresponding point code when the explosive source is excited, and whether there is another point code when the controllable seismic source is excited. If no point code is recorded, it is determined that the segmentation condition is not met.

[0070] The drift judgment module 40 is used to select the daily inspection data of any node and check whether there is GPS drift. If there is drift, it is determined that the segmentation condition is not met, otherwise it enters the seismic trace head detection module.

[0071] Checking GPS time drift is to check the node clock synchronization error. If the error exceeds the preset time threshold, such as 250μs, the obtained seismic data is unqualified. Therefore, if GPS drift exists, it is judged that the segmentation condition is not met.

[0072] The seismic trace header detection module 50 is used to check the seismic trace header of the seismic data. If the preset parameter information is missing, it is determined that the segmentation condition is not met. Otherwise, the process enters the phase judgment module.

[0073] The seismic trace header of the collected node continuous data is checked to see whether it contains information such as line number, point number, position coordinates, and collection parameters. If it contains this information, the conditions for node collection data segmentation and synthesis are met; if it does not contain this information, the conditions for node collection data segmentation and synthesis are not met.

[0074] The phase judgment module 60 is used to divide the common receiving point data formed by segmenting the input node continuous data, obtain the data set processed by linear dynamic correction according to preset rules, and superimpose the data set processed by linear dynamic correction. If a superimposed data line contains multiple strong phases, it is determined that there is a problem with the segmentation.

[0075] Specifically, the common receiving point gathers formed by segmenting the continuous data collected by the input nodes are processed. By giving a speed, linear dynamic correction is performed on the data of the preset offset range to obtain the linear dynamic correction gathered. The linear dynamic correction gathered are superimposed. If multiple positions with amplitudes reaching the preset amplitude threshold appear after superposition, it is determined that there is a problem with the segmentation.

[0076] The present invention performs quality control inspection on the segmentation of node seismic acquisition continuous data from multiple angles, such as judging whether the seismic acquisition excitation time and the node reception time are synchronized, whether the excitation source type and excitation content during seismic acquisition excitation meet the requirements, whether there is GPS drift in the daily inspection data of the node, whether the seismic trace header of the seismic data lacks preset parameter information, and whether there are multiple strong phases in the superposition of the trace set processed by linear dynamic correction, so as to ensure the accuracy of the node segmentation data and thus ensure the correctness of the collected seismic data.

[0077] In addition, an embodiment of the present invention further discloses a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor. The processor executes the node seismic acquisition continuous data segmentation quality control method described in the first embodiment.
