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 development of seismic exploration instruments, the size of seismic field instruments and equipment has been continuously reduced, and GPS receiving technology, data storage technology, new battery technology, and new radio frequency communication technology have been continuously updated, which has promoted the rapid development of node seismic data acquisition systems. The application of node seismic acquisition systems has changed the operation mode of traditional wired instruments, greatly simplified the structure of seismic data acquisition systems, and made field construction faster, more flexible, and more convenient. The main advantages are: First, it can realize infinite avenue acquisition, making the application of ultra-high density and wide-azimuth seismic acquisition technology possible; second, it can realize flexible deployment of field observation systems, and can realize flexible changes in views and receiving point offsets according to terrain, obstacles, etc., which is convenient for field construction and reduces environmental impact; third, the number of field auxiliary equipment is greatly reduced, which greatly saves the number of field carrying equipment, which not only saves transportation costs, but also reduces carbon emissions; fourth, it greatly reduces the number of field construction personnel, which not only reduces the number of field construction personnel, but also reduces the intensity of field labor; fifth, the waiting time during blasting is greatly reduced, and continuous aliasing excitation can also be achieved, which greatly improves the construction efficiency. These are advantages that wired acquisition systems cannot match.

[0003] The 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 downloading 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 recycled, and the seismic data is downloaded from the charging and downloading integrated cabinet. Then, the preset segmentation and synthesis software is used to segment and synthesize the continuous data collected by the node seismic to obtain a common detection point gather or a common shot point gather. Summary of the invention

[0004] The inventors found that in the existing node seismic acquisition continuous data segmentation and synthesis process, the segmentation software provided by the node instruments produced by different manufacturers is used for segmentation. There is no quality control process in the entire segmentation process, and there are problems with the accuracy of the segmentation. Therefore, the present invention proposes a node seismic acquisition continuous data segmentation quality control method and device to ensure the accuracy of the node segmentation data, thereby ensuring 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, and includes the following steps:

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

[0007] According to the time of seismic acquisition excitation 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 type of excitation source during seismic acquisition excitation, 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 to check whether there is GPS drift. If there is drift, it is determined that the segmentation condition is not met, otherwise, proceed to the next step;

[0010] 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;

[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] Further, 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 if it meets the preset threshold, the scanning signal is judged to be correct.

[0016] Further, 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 both explosive sources and vibrators are used 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 judged that the segmentation conditions are not met.

[0018] Further, 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, which also includes:

[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 input node continuous data 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 has multiple strong phases, it is judged that there is a problem in 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 speed, linear dynamic correction is performed on the data of the preset range of offset distance to obtain the linear dynamic correction processed gathers. The linear dynamic correction processed gathers are superimposed. If there are multiple positions with amplitudes reaching the preset amplitude threshold after superposition, it is judged that there is a problem in 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 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, 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 the preset rules. If it meets the requirements, it enters the drift judgment module;

[0027] The drift judgment module is used to select the daily inspection data of any node to check whether there is GPS drift. If there is drift, it is judged 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 it enters the phase judgment module;

[0029] The phase judgment module is used to divide the common receiving point data set 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 judged that there is a problem in the division.

[0030] In a third aspect, 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, 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 beneficial effects of the present invention compared with the prior art are as follows:

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

[0040] Embodiment 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, steps S110-S160 are included, 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 includes daily inspection data, log files, and seismic data.

[0043] In practical applications, the 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 downloading 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 recycled, and the seismic data is downloaded from the charging and downloading integrated cabinet. Then, the preset segmentation and synthesis software is used to segment and synthesize the continuous data collected by the node seismic data to obtain the 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, and if they are synchronized, execute the next step.

[0046] During seismic acquisition, an excitation time is recorded when the excitation system is excited, and a time is also recorded when the node unit collects data (recorded in the log file). The time synchronization of 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, determine the type of excitation source during seismic acquisition excitation, and check whether the data content corresponding to the excitation source meets the requirements according to the preset rules. If so, execute the next step.

[0048] In some embodiments, if vibrator excitation is used during seismic acquisition, the correctness of the vibrator scanning signal is checked. During field seismic acquisition, when vibrator excitation is used, the vibrator will generate a true reference scanning signal, and the correctness of the scanning signal is determined by checking the time length and other information of the true reference scanning signal.

[0049] In other embodiments, the seismic acquisition excitation uses two seismic source systems (using explosive seismic sources and controllable seismic sources at the same time), and the node unit records will simultaneously obtain the common receiving point gather data obtained by using the explosive seismic source and the common receiving point gather data obtained by using the controllable seismic source. Therefore, for the same node, it can be checked whether the well gun common receiving point gather data and the controllable seismic source common receiving point gather data are recorded respectively. If there are records, the subsequent segmentation and synthesis process can be guaranteed. If there are no records, it means that the data record is incorrect and the conditions for segmentation and synthesis are not met.

[0050] In addition, when using explosive source excitation, a mark will be given to indicate that this is using explosive source excitation, and when using controllable source excitation, a mark will also be given to indicate that this is using explosive source excitation. These two marks are called point codes. Therefore, the type of excitation source can also be distinguished by judging whether the excitation point code is recorded. If the point code is not recorded, it is judged 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 seismic source 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, selecting the daily inspection data of any node to check whether there is GPS drift, if there is drift, it is determined that the segmentation 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, checking 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 does, the conditions for node collection data segmentation and synthesis are met; if it does not, 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, and 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 a lot of 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 can be 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, select a certain range of offset distances (such as 1000-2000 meters) for linear dynamic correction processing. After processing, the linear dynamic correction processed gather is obtained. The linear dynamic correction processed gather is superimposed (for example, the process of stacking 5 seismic traces to obtain 1 seismic trace, such as Figure 3 If there are multiple strong phases with large amplitudes after superposition, it means that 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 receiving time are synchronized, whether the excitation source type and the excitation content during the 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, thereby ensuring the correctness of the collected seismic data.

[0060] Embodiment 2

[0061] 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 10, a synchronization judgment module 20, an excitation source judgment module 30, a drift judgment module 40, a seismic trace head detection module 50, and a phase judgment 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 excitation source judgment module is entered.

[0065] During seismic acquisition, an excitation time is recorded when the excitation system is excited, and a time is also recorded when the node unit collects data (recorded in the log file). The time synchronization of 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 it meets the requirements, it enters the drift judgment module.

[0067] In practical applications, if the excitation source judgment module 30 determines that the controllable vibrator is used for excitation during seismic acquisition, the excitation source judgment module 30 is also used to check whether the controllable vibrator scanning signal is correct. During seismic field acquisition, when the controllable vibrator is used for excitation, the controllable vibrator will generate a true reference scanning signal. By checking the time length and other information of the true reference scanning signal, the correctness of the scanning signal is judged.

[0068] If the excitation source judgment module 30 determines that two seismic source systems are used for seismic acquisition excitation (explosive seismic source and controllable seismic source are used simultaneously), the excitation source judgment module 30 is also used to check whether the well-gun common receiving point gather data and the controllable seismic source common receiving point gather data are recorded respectively for the same node. 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 simultaneously), 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 to check whether there is GPS drift. If there is drift, it is judged 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 it 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 does, the conditions for node collection data segmentation and synthesis are met; if it does not, 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 set 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 judged that there is a problem in the division.

[0075] Specifically, the common receiving point gathers formed by segmenting the continuous data collected by the input nodes are processed, and a linear dynamic correction is performed on the data of the preset offset range by giving a speed to obtain the linear dynamic correction processed gathers. The linear dynamic correction processed gathers are superimposed. If there are multiple positions where the amplitude reaches the preset amplitude threshold after superposition, it is determined that there is a problem in 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 receiving time are synchronized, whether the excitation source type and the excitation content during the 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, thereby ensuring 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, wherein the processor executes the node seismic acquisition continuous data segmentation quality control method described in Embodiment 1.

[0078] Based on the same inventive concept, an embodiment of the present invention further provides a computer-readable storage medium, which stores the node seismic acquisition continuous data segmentation quality control method recorded in the first embodiment.
