Description

Technical Field

[0001] This invention relates to the field of seismic exploration technology, and more specifically, to a method, apparatus, storage medium, and electronic device for determining quality control parameters. Background Technology

[0002] In related technologies, dual-source gun control systems are often used in marine data collection operations. The dual sources are a left source and a right source, i.e., two seismic sources. During the production process, the firing state of the left source air gun is controlled by collecting near-field data generated by the left source, or the firing state of the right source air gun is controlled by collecting near-field data generated by the right source. This scheme does not consider the near-field data received by the right source when the left source is firing, or the near-field data signal received by the left source when the right source is firing, which leads to errors in the quality control of the dual-source gun control system. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the related art.

[0004] Therefore, the first aspect of the present invention is to provide a method for determining quality control parameters.

[0005] A second aspect of the present invention is to provide a device for determining quality control parameters.

[0006] A third aspect of the present invention is to provide a device for determining quality control parameters.

[0007] A fourth aspect of the present invention is to provide a readable storage medium.

[0008] The fifth aspect of the present invention is to provide an electronic device.

[0009] In view of this, according to one aspect of the present invention, a method for determining quality control parameters is proposed for a dual-source gun control system, the dual-source gun control system including an air gun array, the air gun array including a first source gun array and a second source gun array, the method comprising: acquiring first near-field data received by the second source gun array when the first source gun array is excited; preprocessing the first near-field data to determine first time data; and determining quality control parameters of the first source gun array based on the first time data, the quality control parameters being used to adjust the operation of the first source gun array.

[0010] It should be noted that the method proposed in this invention is mainly used in dual-source gun control systems. The execution subject of the method for determining the quality control parameters can be a device for determining the quality control parameters. In order to more clearly explain the method for determining the quality control parameters proposed in this invention, the following technical solution uses a device for determining the quality control parameters as the execution subject of the method for determining the quality control parameters for illustrative purposes.

[0011] In this technical solution, the aforementioned dual-source gun control system is a widely used system in marine seismic exploration. It mainly includes an air gun array, which consists of a first source gun array and a second source gun array.

[0012] Specifically, the determination device acquires first near-field data received by the second seismic gun array when the first source gun array is activated. Specifically, the first near-field data records characteristic waveforms, including reflected waves, direct waves, virtual reflected waves, and refracted waves. Based on this information, information relevant to marine seismic exploration can be analyzed; however, this information has not been effectively applied in related technologies. Therefore, the determination device needs to acquire the first near-field data when the first source gun array is activated in order to analyze and process this information and provide more parameter support for subsequent exploration.

[0013] Furthermore, the determining device preprocesses the aforementioned first near-field data to determine the first time data. Specifically, since the characteristic waveforms in the first near-field data may contain clutter that affects data analysis, the determining device needs to preprocess the first near-field data.

[0014] Specifically, the determining device determines the aforementioned first time data by extracting the time information of the characteristic waveform of the first near-field data after clutter removal.

[0015] Furthermore, the determining device determines the quality control parameters used to adjust the operation of the first seismic gun array based on the aforementioned first-time data. Specifically, based on the first-time data, different calculation formulas can be used to calculate quality control parameters such as the distance between the first seismic gun array and the air gun boat of the dual-source gun control system, the time difference between the received reflected waves from the first and second seismic gun arrays, and the water depth at the center point of the first and second seismic gun arrays. Based on these parameters, the operation status of the first seismic gun array can be understood, facilitating timely adjustment and maintenance of the first seismic gun array in case of abnormal operation.

[0016] In related technologies, the quality control of the vibrating source gun array excited in a dual-source gun control system does not take into account the near-field data received by the second vibrating source gun array when the first vibrating source gun array is excited, or the near-field data received by the second vibrating source gun array when the first vibrating source gun array is excited, resulting in errors in the quality control of the excited vibrating source gun array.

[0017] Therefore, in the technical solution of the present invention, when the first source gun array is excited, the determining device acquires the first near-field data received by the second source gun array, and determines the quality control parameters that can be used to adjust the operation of the first source gun array based on the first time data determined by preprocessing the first near-field data. In this way, the quality control of the excited source gun array in the dual-source gun control system takes into account the near-field data received by the unexcited source gun array, ensuring the accuracy of the quality control of the excited source gun array in the dual-source gun control system, thereby improving the stability of the operation of the dual-source gun control system.

[0018] Furthermore, the method for determining quality control parameters proposed according to the above-described technical solution of the present invention may also have the following additional technical features:

[0019] In the above technical solution, the step of preprocessing the first near-field data to determine the first time data specifically includes: using a preset model to pick up the first arrival time of the characteristic waveforms received by multiple detectors in the second source gun array in the first near-field data, so as to determine the first time data.

[0020] In this technical solution, the aforementioned initial arrival time is the time of the starting point of the characteristic waveform in the first near-field data.

[0021] Specifically, the determining device uses a preset model to pick up the first arrival times of the characteristic waveforms received by multiple detectors in the second source gun array in the first near-field data, so as to determine the aforementioned first time data.

[0022] Specifically, the aforementioned preset model is based on the method and results of first arrival time acquisition of characteristic waveforms from existing near-field data. Training data is generated, and through artificial intelligence technology, machine learning algorithm optimization and combination, and autonomous feature learning, a first arrival time acquisition model suitable for different sea state conditions is established.

[0023] Specifically, in related technologies, seismic signals can be picked up through artificial intelligence technology or human-computer interaction. In the technical solution of this invention, a predictive model that can be used to pick up the first arrival time of different characteristic waveforms in near-field data is constructed through artificial intelligence technology. That is, the artificial intelligence technology is extended to the scheme of picking up characteristic waveforms in near-field data, realizing the accurate picking up of the first arrival time of different characteristic waveforms. This enables subsequent steps to accurately determine different quality control parameters, thereby accurately controlling the function of the dual-source gun control system.

[0024] Specifically, the determining device first filters out clear characteristic waveforms (i.e. waveforms after removing clutter) from the first near-field data using a preset model, then determines the time information of the starting point of the characteristic waveform using the preset model, and records this time information. The recorded time information is the aforementioned first time data.

[0025] In this technical solution, the determining device can quickly pick up the first arrival times of multiple characteristic waveforms in the first near-field data through a pre-built and trained preset model. This improves the efficiency and accuracy of determining the first-time data.

[0026] In the above technical solution, the dual-source gun control system also includes an air gun boat. Quality control parameters include the distance between the first source gun array and the air gun boat. The steps for determining the quality control parameters based on the first time data specifically include: determining a first duration based on the first target time and the excitation time of the first source gun array in the first time data; obtaining the first distance between the first and second source gun arrays and the seawater flow velocity in the area where the air gun boat is located; and determining the distance between the first source gun array and the air gun boat based on the first time data, the first distance, and the seawater flow velocity. The first target time is the arrival time of the characteristic waveform corresponding to the target detector among the multiple detectors in the second source gun array, or the average of the arrival times of the characteristic waveforms received by the multiple detectors in the second source gun array.

[0027] In this technical solution, the aforementioned dual-source gun control system also includes an air gun boat, and the aforementioned quality control parameter is specifically the distance between the first source gun array and the air gun boat; the aforementioned first target time is the initial arrival time of the characteristic waveform received by the target detector among the multiple detectors in the second source gun array, or the average value of the initial arrival times of the characteristic waveforms received by the multiple detectors in the second source gun array.

[0028] Specifically, the process by which the determining device determines the quality control parameters based on the aforementioned first time data is as follows: The determining device first calculates the first duration based on the first target time and the excitation time of the first seismic source gun array. Specifically, the first duration is the travel time of the reflected wave received by the second seismic source gun array after the first seismic source gun array is excited to the air gun boat reflection.

[0029] Furthermore, the device determines the first distance between the first and second seismic source gun arrays and the seawater flow velocity in the area where the air gun boat is located. Specifically, the air gun boat is equipped with a seawater flow velocity detection device, which the device can use to obtain the seawater flow velocity in the area where the air gun boat is located. Since the first distance between the first and second seismic source gun arrays is generally fixed, the device can directly obtain this information from its memory.

[0030] Furthermore, the determining device calculates the distance between the first seismic source gun array and the air gun vessel based on the aforementioned first duration, first spacing, and seawater flow velocity. Specifically, based on the distance between the first seismic source gun array and the air gun vessel, it can be determined whether there is an anomaly in the position of the air gun vessel or the first seismic source gun array.

[0031] In this technical solution, the determining device can determine the first duration based on the first time data. Based on this first duration, the first distance between the first and second seismic gun arrays, and the seawater current velocity in the area where the air-gun vessel is located, the determining device can quickly and accurately calculate the distance between the first seismic gun array and the air-gun vessel using a pre-derived calculation formula. This allows the determining device to determine whether there are any anomalies in the position of the first seismic gun array based on the distance between the two arrays, so that the operating status of the first seismic gun array can be adjusted in a timely manner if an anomaly is found. This ensures the stability and reliability of the dual-source gun control system.

[0032] In the above technical solution, the quality control parameters include travel time difference, which is the time difference between the first and second source gun arrays receiving the reflected wave after the first source gun array is excited. The steps for determining the quality control parameters based on the first time data specifically include: determining the first duration based on the first target time and the excitation time of the first source gun array in the first time data; acquiring the second near-field data received by the first source gun array; picking up the first arrival times of the characteristic waveforms received by multiple detectors in the first source gun array in the second near-field data to determine the second time data; and determining the second duration based on the second time data. The second duration is determined by the second target time in the inter-electrode data and the excitation time of the first seismic gun array; the travel time difference is determined based on the first duration and the second duration; wherein, the first target time is the arrival time of the characteristic waveform corresponding to the target detector among the multiple detectors in the second seismic gun array, or the average of the arrival times of the characteristic waveforms received by the multiple detectors in the second seismic gun array; the second target time is the arrival time of the characteristic waveform corresponding to the target detector among the multiple detectors in the first seismic gun array, or the average of the arrival times of the characteristic waveforms received by the multiple detectors in the first seismic gun array.

[0033] In this technical solution, the aforementioned quality control parameter is specifically the travel time difference, which is the time difference between the first and second source gun arrays receiving the reflected wave after the first source gun array is excited; the aforementioned first target time is the initial arrival time of the characteristic waveform received by the target detector among the multiple detectors in the second source gun array, or the average of the initial arrival times of the characteristic waveforms received by the multiple detectors in the second source gun array; the aforementioned second target time is the initial arrival time of the characteristic waveform corresponding to the target detector among the multiple detectors in the first source gun array, or the average of the initial arrival times of the characteristic waveforms received by the multiple detectors in the first source gun array.

[0034] Specifically, the process by which the determining device determines the quality control parameters based on the aforementioned first time data is as follows: The determining device first calculates the first duration based on the first target time and the excitation time of the first seismic source gun array. Specifically, the first duration is the travel time of the reflected wave received by the second seismic source gun array after the first seismic source gun array is excited to the air gun boat reflection.

[0035] Furthermore, the device acquires the second near-field data received by the first source gun array, and picks up the first arrival times of the characteristic waveforms received by multiple detectors in the second near-field data to determine the second time data. Specifically, the process of picking up the first arrival times of the characteristic waveforms in the second near-field data to determine the second time data is the same as the steps for determining the first time data mentioned above, and will not be repeated here.

[0036] Furthermore, the determining device determines the second duration based on the second target time and the excitation time of the first seismic source gun array in the second time data. Specifically, the second duration is the travel time of the reflected wave received by the first seismic source gun array after it is excited by the air gun boat.

[0037] Furthermore, the determining device calculates the travel time difference based on the first duration and the second duration mentioned above. Specifically, the travel time difference can be used to determine whether there is an anomaly in the detectors of the first or second source gun array.

[0038] In this technical solution, the determining device can determine a first duration based on first time data, a second duration based on second time data obtained from processing second near-field data, and the aforementioned travel time difference based on the first and second durations. This allows the determining device to determine whether there are any abnormalities in the detectors of the first source gun array in subsequent steps, based on the travel time difference, so that the operating state of the first source gun array can be adjusted in a timely manner when an abnormality is found in the detectors. This ensures the stability and reliability of the dual-source gun control system.

[0039] In the above technical solution, the dual-source gun control system also includes an air gun boat. The quality control parameters include the water depth at the center point of the first and second source gun arrays. The steps for determining the quality control parameters based on the first time data specifically include: determining the third duration based on the third target time in the first time data and the excitation time of the first source gun array; obtaining the first distance between the first and second source gun arrays, the second distance between the first source gun array and the water surface, and the seawater flow velocity in the area where the air gun boat is located; determining the water depth at the center point of the first and second source gun arrays based on the third duration, the first distance, the second distance, and the seawater flow velocity; wherein, the third target time is the arrival time of the characteristic waveform corresponding to the target detector among the multiple detectors in the second source gun array, or the average value of the arrival times of the characteristic waveforms received by the multiple detectors in the second source gun array.

[0040] In this technical solution, the aforementioned dual-source gun control system also includes an air gun boat. The aforementioned quality control parameters are specifically the water depth at the center point of the first source gun array and the second source gun array. The aforementioned third target time is the initial arrival time of the characteristic waveform received by the target detector among the multiple detectors in the second source gun array, or the average value of the initial arrival times of the characteristic waveforms received by the multiple detectors in the second source gun array.

[0041] Specifically, the process by which the determining device determines the quality control parameters based on the aforementioned first time data is as follows: The determining device first calculates the third duration based on the third target time and the excitation time of the first seismic source array. Specifically, the third duration is the travel time of the reflected wave from the excitation of the first seismic source array to the second seismic source array.

[0042] Furthermore, the device determines the first distance between the first and second seismic source gun arrays, the second distance between the first seismic source gun array and the water surface, and the seawater current velocity in the area where the air gun boat is located. Specifically, the air gun boat is equipped with a seawater current velocity detection device, which the device can use to obtain the seawater current velocity in the area where the air gun boat is located. Since the first distance between the first and second seismic source gun arrays and the second distance between the first seismic source gun array and the water surface are generally fixed, the device can directly obtain them from its memory.

[0043] Furthermore, the determining device calculates the water depth at the center point of the first and second seismic source gun arrays based on the aforementioned third duration, first spacing, second spacing, and seawater flow velocity. Specifically, based on this water depth, it can be determined whether there is any anomaly in the position of the first seismic source gun array.

[0044] In this technical solution, the determining device can determine a third time interval based on the first time interval data. Based on this third time interval, the first distance between the first and second seismic gun arrays, the second distance between the first seismic gun array and the water surface, and the seawater current velocity in the area where the air gun vessel is located, the determining device can quickly and accurately calculate the water depth at the center point of the first and second seismic gun arrays using a pre-derived calculation formula. This allows the determining device to determine whether there is an anomaly in the position of the first seismic gun array based on the water depth at the center point of the first and second seismic gun arrays, so that the operating status of the first seismic gun array can be adjusted in a timely manner if an anomaly is found. This ensures the stability and reliability of the dual-source gun control system.

[0045] In the above technical solution, after determining the quality control parameters based on the first-time data, the determination method also includes: if the difference between the quality control parameters and the theoretical parameter values ​​is greater than a preset threshold, it is determined that the dual-source gun control system needs maintenance.

[0046] In this technical solution, the above-mentioned theoretical parameter value is the standard value of the quality control parameter when the dual-source gun control system is operating normally, and the above-mentioned preset threshold is the maximum value that the quality control parameter set according to the dual-source gun control system can fluctuate.

[0047] Specifically, after determining the quality control parameters, the determining device also needs to calculate the difference between the quality control parameters and the theoretical parameter values, and compare the difference with the preset threshold.

[0048] Specifically, if the difference between the quality control parameters and the theoretical parameters exceeds a preset threshold, maintenance of the dual-source gun control system is required. In other words, if the difference between the quality control parameters and the theoretical parameters exceeds a preset threshold, it indicates an anomaly in the position of the first source gun array, and maintenance of the dual-source gun control system is necessary.

[0049] In this technical solution, the determining device can determine whether there is an anomaly in the position of the first source gun array based on the relationship between the difference between the quality control parameters and the theoretical parameter values ​​and the preset threshold. This allows for timely maintenance of the dual-source gun control system when an anomaly occurs, ensuring the stability of the dual-source gun control system's operation.

[0050] According to a second aspect of the present invention, a quality control parameter determination device is provided for a dual-source gun control system, the dual-source gun control system including an air gun array, the air gun array including a first source gun array and a second source gun array, the quality control parameter determination device comprising: an acquisition module, configured to acquire first near-field data received by the second source gun array when the first source gun array is excited; a first processing module, configured to preprocess the first near-field data to determine first time data; and a second processing module, configured to determine quality control parameters of the first source gun array based on the first time data, the quality control parameters being parameters used to adjust the operation of the first source gun array.

[0051] In this technical solution, the aforementioned dual-source gun control system is a widely used system in marine seismic exploration. It mainly includes an air gun array, which consists of a first source gun array and a second source gun array.

[0052] Specifically, when the first source gun array is activated, the acquisition module acquires the first near-field data received by the second source gun array. Specifically, the first near-field data records characteristic waveforms, including reflected waves, direct waves, virtual reflected waves, and refracted waves. Based on this information, information relevant to marine seismic exploration can be analyzed; however, this information has not been effectively applied in related technologies. Therefore, when the first source gun array is activated, it is necessary to acquire the first near-field data through the acquisition module to analyze and process this information, providing more parameter support for subsequent exploration.

[0053] Furthermore, the first near-field data is preprocessed by the first processing module to determine the first time data. Specifically, since the characteristic waveforms in the first near-field data may contain clutter that affects data analysis, it is necessary to preprocess the first near-field data by the first processing module.

[0054] Specifically, the first processing module determines the aforementioned first time data by extracting the time information of the characteristic waveform of the first near-field data after removing clutter.

[0055] Furthermore, the second processing module determines quality control parameters for adjusting the operation of the first seismic gun array based on the aforementioned first-time data. Specifically, based on the first-time data, quality control parameters such as the distance between the first seismic gun array and the air gun vessel of the dual-source gun control system, the time difference between the reflected waves received by the first and second seismic gun arrays, and the water depth at the center point of the first and second seismic gun arrays can be calculated using different formulas. These parameters allow for an understanding of the operation of the first seismic gun array, facilitating timely adjustment and maintenance of the first seismic gun array in case of abnormal operation.

[0056] In related technologies, the quality control of the vibrating source gun array excited in a dual-source gun control system does not take into account the near-field data received by the second vibrating source gun array when the first vibrating source gun array is excited, or the near-field data received by the second vibrating source gun array when the first vibrating source gun array is excited, resulting in errors in the quality control of the excited vibrating source gun array.

[0057] Therefore, in the technical solution of this invention, when the first source gun array is excited, the acquisition module acquires the first near-field data received by the second source gun array. The first processing module determines the first time data based on the preprocessing of the first near-field data, and the second processing module determines the quality control parameters used to adjust the operation of the first source gun array based on the first time data. In this way, the quality control of the excited source gun array in the dual-source gun control system comprehensively considers the near-field data received by the unexcited source gun array, ensuring the accuracy of the quality control of the excited source gun array in the dual-source gun control system, thereby improving the stability of the dual-source gun control system operation.

[0075] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments of the present invention and the features thereof can be combined with each other.

[0076] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0077] The following is combined Figures 1 to 12 The present invention provides a detailed description of a method, apparatus, storage medium, and electronic device for determining quality control parameters through specific embodiments and application scenarios.

[0078] Example 1:

[0079] Figure 1 A flowchart illustrating a method for determining quality control parameters according to an embodiment of the present invention is shown. This method is used in a dual-source gun control system, which includes an air gun array comprising a first seismic source gun array and a second seismic source gun array. The determination method includes:

[0080] S102, when the first source gun array is excited, acquire the first near-field data received by the second source gun array;

[0081] S104, preprocess the first near-field data to determine the first time data;

[0082] S106, determine the quality control parameters of the first seismic source gun array based on the first-time data, and use the quality control parameters to adjust the operation of the first seismic source gun array.

[0083] It should be noted that the method proposed in this invention is mainly used in dual-source gun control systems. The execution subject of the method for determining the quality control parameters can be a device for determining the quality control parameters. In order to more clearly explain the method for determining the quality control parameters proposed in this invention, the following embodiments use a device for determining the quality control parameters as the execution subject of the method for determining the quality control parameters for illustrative purposes.

[0084] In this embodiment, the aforementioned dual-source gun control system is a widely used system in marine seismic exploration. It mainly includes an air gun array, as shown in the schematic diagram below. Figure 2 As shown, through Figure 2 It can be seen that the air gun array includes a first source gun array and a second source gun array.

[0085] Specifically, the determination device acquires first near-field data received by the second seismic gun array when the first source gun array is activated. Specifically, the first near-field data records characteristic waveforms, including reflected waves, direct waves, virtual reflected waves, and refracted waves. Based on this information, information relevant to marine seismic exploration can be analyzed; however, this information has not been effectively applied in related technologies. Therefore, the determination device needs to acquire the first near-field data when the first source gun array is activated in order to analyze and process this information and provide more parameter support for subsequent exploration.

[0086] For example, a schematic diagram of the first near-field data is shown below. Figure 3 As shown, according to Figure 3 It is possible to determine the waveforms, such as reflected waves, received by different detectors in the second source gun array, as well as the timing information of these waveforms, for example... Figure 3 The diagram shows the water depth characteristic waveforms at the center of adjacent gun arrays. Taking this as an example, based on the multiple characteristic waveform jump points (i.e., the points corresponding to the dashed line L), and using the time information corresponding to these jump points combined with the corresponding calculation formulas, the water depth at the center point between the first and second source gun arrays can be calculated. Based on this water depth, the operating status of the first source gun array can be understood. Therefore, it is evident that the first near-field data has high reference value for the control of the dual-source gun control system.

[0087] Furthermore, the determining device preprocesses the aforementioned first near-field data to determine the first time data. Specifically, since the characteristic waveforms in the first near-field data may contain clutter that affects data analysis, the determining device needs to preprocess the first near-field data.

[0088] Specifically, the determining device determines the aforementioned first time data by extracting the time information of the characteristic waveform of the first near-field data after clutter removal.

[0089] Furthermore, the determining device determines the quality control parameters used to adjust the operation of the first seismic gun array based on the aforementioned first-time data. Specifically, based on the first-time data, different calculation formulas can be used to calculate quality control parameters such as the distance between the first seismic gun array and the air gun boat of the dual-source gun control system, the time difference between the received reflected waves from the first and second seismic gun arrays, and the water depth at the center point of the first and second seismic gun arrays. Based on these parameters, the operation status of the first seismic gun array can be understood, facilitating timely adjustment and maintenance of the first seismic gun array in case of abnormal operation.

[0090] In related technologies, the quality control of the vibrating source gun array excited in a dual-source gun control system does not take into account the near-field data received by the second vibrating source gun array when the first vibrating source gun array is excited, or the near-field data received by the second vibrating source gun array when the first vibrating source gun array is excited, resulting in errors in the quality control of the excited vibrating source gun array.

[0091] Therefore, in the embodiments of the present invention, when the first source gun array is excited, the determining device acquires the first near-field data received by the second source gun array, and determines the quality control parameters that can be used to adjust the operation of the first source gun array based on the first time data determined by preprocessing the first near-field data. In this way, the quality control of the excited source gun array in the dual-source gun control system takes into account the near-field data received by the unexcited source gun array, ensuring the accuracy of the quality control of the excited source gun array in the dual-source gun control system, thereby improving the stability of the operation of the dual-source gun control system.

[0095] S406, determine the quality control parameters of the first seismic source gun array based on the first-time data, and use the quality control parameters to adjust the operation of the first seismic source gun array.

[0096] In this embodiment, the aforementioned initial arrival time is the time of the starting point of the characteristic waveform in the first near-field data.

[0097] Specifically, the determining device uses a preset model to pick up the first arrival times of the characteristic waveforms received by multiple detectors in the second source gun array in the first near-field data, so as to determine the aforementioned first time data.

[0098] Specifically, the aforementioned preset model is based on the method and results of first arrival time acquisition of characteristic waveforms from existing near-field data. Training data is generated, and through artificial intelligence technology, machine learning algorithm optimization and combination, and autonomous feature learning, a first arrival time acquisition model suitable for different sea state conditions is established.

[0099] Specifically, in related technologies, seismic signals can be picked up through artificial intelligence technology or human-computer interaction. In the embodiments of the present invention, a predictive model that can be used to pick up the first arrival time of different characteristic waveforms in near-field data is constructed through artificial intelligence technology. That is, artificial intelligence technology is extended to the scheme of picking up characteristic waveforms in near-field data, realizing the accurate picking up of the first arrival time of different characteristic waveforms. This enables subsequent steps to accurately determine different quality control parameters, thereby accurately controlling the function of the dual-source gun control system.

[0100] Specifically, the determining device first filters out clear characteristic waveforms (i.e. waveforms after removing clutter) from the first near-field data using a preset model, then determines the time information of the starting point of the characteristic waveform using the preset model, and records this time information. The recorded time information is the aforementioned first time data.

[0101] In this embodiment, the determining device can quickly pick up the first arrival times of multiple feature waveforms in the first near-field data using a pre-built and trained preset model. This improves the efficiency and accuracy of determining the first-time data.

[0107] S510, based on the first time data, the first spacing and the seawater flow velocity, determine the distance between the first seismic source gun array and the air gun boat.

[0108] The first target time is the arrival time of the characteristic waveform corresponding to the target detector among the multiple detectors in the second source gun array, or the average value of the arrival times of the characteristic waveforms received by the multiple detectors in the second source gun array.

[0109] In this embodiment, the dual-source gun control system further includes an air gun boat, and the quality control parameter is specifically the distance between the first source gun array and the air gun boat; the first target time is the initial arrival time of the characteristic waveform received by the target detector among the multiple detectors in the second source gun array, or the average of the initial arrival times of the characteristic waveforms received by the multiple detectors in the second source gun array.

[0110] Specifically, the process by which the determining device determines the quality control parameters based on the aforementioned first time data is as follows: The determining device first calculates the first duration based on the first target time and the excitation time of the first seismic source gun array. Specifically, the first duration is the travel time of the reflected wave received by the second seismic source gun array after the first seismic source gun array is excited to the air gun boat reflection.

[0111] Furthermore, the device determines the first distance between the first and second seismic source gun arrays and the seawater flow velocity in the area where the air gun boat is located. Specifically, the air gun boat is equipped with a seawater flow velocity detection device, which the device can use to obtain the seawater flow velocity in the area where the air gun boat is located. Since the first distance between the first and second seismic source gun arrays is generally fixed, the device can directly obtain this information from its memory.

[0112] Furthermore, the determining device calculates the distance between the first seismic source gun array and the air gun vessel based on the aforementioned first duration, first spacing, and seawater flow velocity. Specifically, based on the distance between the first seismic source gun array and the air gun vessel, it can be determined whether there is an anomaly in the position of the air gun vessel or the first seismic source gun array.

[0113] For example, according to Figure 6 The schematic diagram of the dual-source gun control system shown illustrates the formula for calculating the distance between the first source gun array and the air gun boat based on the aforementioned first duration, first spacing, and seawater flow velocity. The formula is as follows:

[0114]

[0115]

[0116] T = T1 + T2 (Equation 3);

[0117] Wherein, D represents the first spacing mentioned above, H1 represents the distance between the first seismic source gun array and the air gun boat, T represents the travel time of the reflected wave received by the second seismic source gun array after the first seismic source gun array is excited and reflected by the air gun boat, T1 represents the travel time of the first seismic source gun array being excited and reflected by the air gun boat, and T2 represents the travel time of the reflected wave received by the second seismic source gun array from the air gun boat.

[0118] In this embodiment, the determining device can determine a first duration based on first time data. Using this first duration, the first distance between the first and second seismic gun arrays, and the seawater current velocity in the area where the air-gun vessel is located, the determining device can quickly and accurately calculate the distance between the first seismic gun array and the air-gun vessel using a pre-derived calculation formula. This allows the determining device to determine whether there are any anomalies in the position of the first seismic gun array based on the distance between the two arrays, so that it can promptly adjust the operating state of the first seismic gun array if an anomaly is found. This ensures the stability and reliability of the dual-source gun control system.

[0132] Furthermore, the determining device calculates the travel time difference based on the first duration and the second duration mentioned above. Specifically, the travel time difference can be used to determine whether there is an anomaly in the detectors of the first or second source gun array.

[0133] In this embodiment, the determining device can determine a first duration based on first time data, a second duration based on second time data obtained from processing second near-field data, and the aforementioned travel time difference based on the first and second durations. This allows the determining device to determine whether there is an anomaly in the detectors of the first source gun array in subsequent steps based on the travel time difference, so that the operating state of the first source gun array can be adjusted in a timely manner when an anomaly is found in the detectors. This ensures the stability and reliability of the dual-source gun control system.

Specifically, the third duration is the travel time of the reflected wave from the excitation of the first seismic source array to the second seismic source array.

[0143] Furthermore, the device determines the first distance between the first and second seismic source gun arrays, the second distance between the first seismic source gun array and the water surface, and the seawater current velocity in the area where the air gun boat is located. Specifically, the air gun boat is equipped with a seawater current velocity detection device, which the device can use to obtain the seawater current velocity in the area where the air gun boat is located. Since the first distance between the first and second seismic source gun arrays and the second distance between the first seismic source gun array and the water surface are generally fixed, the device can directly obtain them from its memory.

[0144] Furthermore, the determining device calculates the water depth at the center point of the first and second seismic source gun arrays based on the aforementioned third duration, first spacing, second spacing, and seawater flow velocity. Specifically, based on this water depth, it can be determined whether there is any anomaly in the position of the first seismic source gun array.

[0145] For example, according to Figure 9 The schematic diagram of the dual-source gun control system shown illustrates the formula for calculating the water depth at the center point of the first and second source gun arrays based on the aforementioned third duration, first spacing, second spacing, and seawater flow velocity. The formula is as follows:

[0146]

Using this third duration, the first distance between the first and second seismic gun arrays, the second distance between the first seismic gun array and the water surface, and the seawater current velocity in the area where the air gun vessel is located, the determining device can quickly and accurately calculate the water depth at the center point of the first and second seismic gun arrays using a pre-derived calculation formula. This allows the determining device to determine whether there is an anomaly in the position of the first seismic gun array based on the water depth at the center point of the first and second seismic gun arrays, so that the operating state of the first seismic gun array can be adjusted in a timely manner if an anomaly is found. This ensures the stability and reliability of the dual-source gun control system.

[0155] S1008. If the difference between the quality control parameter and the theoretical parameter value is greater than the preset threshold, it is determined that maintenance of the dual-source gun control system is required.

[0156] In this embodiment, the theoretical parameter value is the standard value of the quality control parameter when the dual-source gun control system is operating normally, and the preset threshold is the maximum value that the quality control parameter set according to the dual-source gun control system can fluctuate.

[0157] Specifically, after determining the quality control parameters, the determining device also needs to calculate the difference between the quality control parameters and the theoretical parameter values, and compare the difference with the preset threshold.

[0158] Specifically, if the difference between the quality control parameters and the theoretical parameters exceeds a preset threshold, maintenance of the dual-source gun control system is required. In other words, if the difference between the quality control parameters and the theoretical parameters exceeds a preset threshold, it indicates an anomaly in the position of the first source gun array, and maintenance of the dual-source gun control system is necessary.

[0159] In this embodiment, the determining device can determine whether there is an anomaly in the position of the first source gun array based on the relationship between the difference between the quality control parameters and the theoretical parameter values ​​and the preset threshold. This allows the dual-source gun control system to be maintained in a timely manner when an anomaly occurs, thus ensuring the stability of the dual-source gun control system.

This quality control parameter determination device 1100 is used in a dual-source gun control system, which includes an air gun array comprising a first seismic source gun array and a second seismic source gun array. The quality control parameter determination device 1100 includes: an acquisition module 1102, used to acquire first near-field data received by the second seismic source gun array when the first seismic source gun array is excited; a first processing module 1104, used to preprocess the first near-field data to determine first time data; and a second processing module 1106, used to determine the quality control parameters of the first seismic source gun array based on the first time data. The quality control parameters are parameters used to adjust the operation of the first seismic source gun array.

[0162] In this embodiment, the aforementioned dual-source gun control system is a widely used system in marine seismic exploration. It mainly includes an air gun array, which includes a first source gun array and a second source gun array.

[0163] Specifically, when the first seismic gun array is activated, the acquisition module 1102 acquires the first near-field data received by the second seismic gun array. Specifically, the first near-field data records characteristic waveforms, including reflected waves, direct waves, virtual reflected waves, and refracted waves. Based on this information, information related to marine seismic exploration can be analyzed; however, this information has not been effectively applied in related technologies. Therefore, when the first seismic gun array is activated, it is necessary to acquire the first near-field data through the acquisition module 1102 to analyze and process this information, providing more parameter support for subsequent exploration.

[0164] Furthermore, the first near-field data is preprocessed by the first processing module 1104 to determine the first time data. Specifically, since the characteristic waveforms in the first near-field data may contain noise that affects data analysis, it is necessary to preprocess the first near-field data by the first processing module 1104.

[0165] Specifically, the first processing module 1104 determines the aforementioned first time data by extracting the time information of the characteristic waveform of the first near-field data after removing clutter.

[0166] Furthermore, the second processing module 1106 determines quality control parameters for adjusting the operation of the first seismic gun array based on the aforementioned first time data.

Based on these parameters, the operation status of the first seismic gun array can be understood, facilitating timely adjustment and maintenance of the first seismic gun array in case of abnormal operation.

[0167] In related technologies, the quality control of the vibrating source gun array excited in a dual-source gun control system does not take into account the near-field data received by the second vibrating source gun array when the first vibrating source gun array is excited, or the near-field data received by the second vibrating source gun array when the first vibrating source gun array is excited, resulting in errors in the quality control of the excited vibrating source gun array.

The second processing module 1106 is also used to pick up the first arrival time of the characteristic waveforms received by multiple detectors in the first source gun array in the second near-field data to determine the second near-field data. Time data; a second duration is determined based on the second target time and the excitation time of the first seismic gun array in the second time data; the travel time difference is determined based on the first duration and the second duration; wherein, the first target time is the arrival time of the characteristic waveform corresponding to the target detector among the multiple detectors in the second seismic gun array, or the average of the arrival times of the characteristic waveforms received by the multiple detectors in the second seismic gun array; the second target time is the arrival time of the characteristic waveform corresponding to the target detector among the multiple detectors in the first seismic gun array, or the average of the arrival times of the characteristic waveforms received by the multiple detectors in the first seismic gun array.

[0172] Furthermore, in the above embodiments, the dual-source gun control system also includes an air gun boat. The quality control parameters include the water depth at the center point of the first and second source gun arrays. The second processing module 1106 is also used to determine a third duration based on the third target time in the first time data and the excitation time of the first source gun array.
