Abstract
Description
Technical Field
[0001] This application relates to the field of quality control technology for seismic data acquisition process in geophysical exploration, specifically to a method, apparatus, computer equipment, and storage medium for quantitative quality control of acquisition station channels. Background Technology
[0002] Currently, seismic data acquisition in the petroleum industry primarily utilizes two types of seismic instruments: nodal instruments and wired instruments. When using nodal seismographs, the actual field location of the nodal station and the corresponding geophone station chainage are typically matched with indoor data using coordinates recorded by a GPS module built into the nodal station or through the deployment report (containing the station serial number and geophone station chainage information). Both methods ensure 100% matching between the nodal station and the actual working geophone station chainage. However, wired seismic instruments only have analog-to-digital converters in the acquisition station and lack built-in GPS positioning devices. Figure 1 As shown, when a new detector line (a collective term for several detector points with the same line number) is added to the acquisition array (a collective term for receiving equipment with dozens of detector lines), the instrument operator completes the matching relationship between the station number of the entire detector and the station number of the detector by setting two or more stations with the new detector line's size number.
[0003] When the surface of the work area is relatively simple, the above method ensures that all stations are matched with their corresponding receiver station numbers by setting two control points on the receiver line. However, when the surface obstacles are complex, such as during construction in urban areas, the cable connecting two acquisition stations often lacks sufficient length due to the influence of buildings. During the construction of wired seismic instruments, detours are required when encountering obstacles; that is, the operator needs to set each acquisition station corresponding to the detour line as a detour. During construction in urban areas, a single receiver line often encounters multiple detour settings, increasing the probability of incorrect setup.
[0004] In existing technologies, operators verify the correctness of the arrangement by performing detector tapping tests on different detector points at both ends of the detector line; indoor quality control personnel verify the correspondence between the station and detector point chainages by comparing daily inspection data from different batches. However, these quality control methods cannot guarantee 100% accuracy in verifying the correspondence between the station and detector point chainages during operator field checks; and indoor quality control personnel's cross-checking of daily inspection data from different batches cannot detect situations where newly arrived arrangements are incorrectly set up.
[0005] Seismic acquisition data is the foundation for subsequent processing and interpretation. When the actual working location of the seismic station does not match the station number (including coordinate information) of the receiver, it provides incorrect information for data inversion in later processing, which will seriously affect subsequent seismic profiles and structural interpretation. For these reasons, there is an urgent need for a method for quantitative quality control of acquisition station cross-tracking. Summary of the Invention
[0006] This application provides a method, apparatus, computer equipment, and storage medium for quantitative quality control of data acquisition stations.
[0007] The first aspect of this application provides a method for quantitative quality control of data acquisition station cross-channels, including:
[0008] Obtain seismic data corresponding to each seismic trace in the target work area;
[0009] Static correction is performed on the seismic data corresponding to each seismic trace, and single-shot data received by the target quality control receiver is extracted from the corrected seismic data.
[0010] Extract the offset distance between each detector point and different shot points in the target quality control detector line from the single-shot data received from the target quality control detector line;
[0011] By comparing the first arrival times of all geophones with the same offset, geophones that do not meet the preset requirements are designated as geophones to be checked.
[0012] In an optional embodiment of this application, obtaining seismic data corresponding to each seismic trace in the target work area includes:
[0013] Seismic data of the target work area is acquired, and seismic data corresponding to each seismic trace is extracted from the seismic data of the target work area. In the seismic data, the shot point coordinates and elevation are the actual working position of the controllable source plate, and the receiver point is the coordinates and elevation information corresponding to the center of the receiver assembly.
[0014] In an optional embodiment of this application, static correction is performed on the seismic data corresponding to each seismic trace, including:

[0016] In an optional embodiment of this application, after extracting single-shot data received by the target quality control receiver from the corrected seismic data, the method further includes:
[0017] Determine the theoretical offset distribution of the target quality control detector line as a reference value for limiting the offset in the next step;

[0021] Obtain the station number of each detector point on the target quality control detector line;
[0022] Based on the correspondence between the acquisition station serial number and the receiver station number, seismic data of different shots received at each receiver point are obtained from the acquisition station corresponding to the target quality control receiver line.

[0026] For cases where a single acquisition station corresponds to more than one geophone on the target quality control geophone line, the seismic data of different geophones in the same acquisition station are divided into seismic data from different shots received by each geophone, according to the station number of different geophones in the same acquisition station.

The actual time difference is the ratio between the difference between the shot and the receiver distance and the surface velocity.
[0029] For all geophones with the same shot-receiver distance relative to different shot points, if the error between the initial arrival time and the actual time of any geophone among all geophones is greater than the second preset threshold, the current geophone is taken as the geophone to be checked, where the actual time is the ratio between the shot-receiver distance and the ground velocity.

[0052] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.
[0053] Please see Figure 2 The data acquisition station cross-channel quantitative quality control method provided in this application includes the following steps 100 to 400:
[0054] Step 100: Obtain the seismic data corresponding to each seismic trace in the target work area;
[0055] Step 200: Perform static correction on the seismic data corresponding to each seismic trace, and extract the single-shot data received by the target quality control receiver from the corrected seismic data.
[0056] Step 300: Extract the offset distance between each detector point and different shot points in the target quality control detector line from the single-shot data received from the target quality control detector line.
[0057] Step 400: Compare the first arrival times of all detectors with the same offset distance, and designate detectors that do not meet the preset requirements as detectors to be checked.
[0058] In an optional embodiment of this application, step 100, obtaining seismic data corresponding to each seismic trace in the target work area, includes:
[0059] Seismic data of the target work area is acquired, and seismic data corresponding to each seismic trace is extracted from the seismic data of the target work area. In the seismic data, the shot point coordinates and elevation are the actual working position of the controllable source plate, and the receiver point is the coordinates and elevation information corresponding to the center of the receiver assembly.
[0060] In an optional embodiment of this application, the seismic data of the target work area is processed to obtain the offset information corresponding to each seismic trace. The shot point coordinates and elevation are used as the actual working position of the controllable source plate, and the receiver point is used as the coordinates and elevation information corresponding to the center of the receiver assembly. This can eliminate the influence of other factors on the first arrival.
[0061] In an optional embodiment of this application, step 200 involves static correction of the seismic data corresponding to each seismic trace, including:
[0062] By using the first-arrival refraction static correction method or the elevation static correction method, the seismic data corresponding to each seismic trace are statically corrected to be on the same reference plane.
[0063] In an optional embodiment of this application, static correction is performed on the seismic data to ensure that the seismic data are on the same reference plane, thereby eliminating the influence of differences in physical point elevations on the judgment results and eliminating the influence of differences in shot receiver elevations and low-velocity zones on the first arrival.
[0064] In an optional embodiment of this application, single-shot data received by the target quality control geophone is extracted from the corrected seismic data. Generally, the near-shot receiving geophone is extracted to obtain seismic data with only one receiving line for each shot, which can ensure clear first arrival and takeoff.
[0065] In an optional embodiment of this application, after extracting the single-shot data received by the target quality control receiver from the corrected seismic data in step 200, the method further includes:
[0066] Determine the theoretical offset distribution of the target quality control detector line as a reference value for limiting the offset in the next step;
[0067] The data is subject to offset limits, and seismic traces with offsets within a preset range are output.
[0068] Seismic traces with the same offset are placed in a single trace set file to provide the first arrival times of each trace with the same offset.
[0069] In an optional embodiment of this application, step 300, extracting the offset distance between each receiver point and different shot points in the target quality control receiver line from the single-shot data received from the target quality control receiver line, includes:
[0070] Obtain the station number of each detector point on the target quality control detector line;
[0071] Based on the correspondence between the acquisition station serial number and the receiver station number, seismic data of different shots received at each receiver point are obtained from the acquisition station corresponding to the target quality control receiver line.
[0072] The shot-receiver distance between each receiver and different shot points is extracted from the seismic data of different shots received from each receiver.
[0073] In an optional embodiment of this application, based on the correspondence between acquisition station serial numbers and receiver station chain numbers, seismic data from different shots received at each receiver point are obtained from the acquisition station corresponding to the target quality control receiver line, including:
[0074] See Figure 3 According to Table 1 below, for a single acquisition station corresponding to a single receiver point on the target quality control receiver line, the seismic data of the acquisition station is used as the seismic data of different shots received by each receiver point, based on the correspondence between the acquisition station serial number and the receiver point station number.
[0075] See Figure 4 According to Table 2 below, for cases where a single acquisition station corresponds to more than one geophone on the target quality control geophone line, the seismic data of different geophones in the same acquisition station are divided into seismic data of different shots received by each geophone, based on the station number of different geophones in the same acquisition station.

[0080] In an optional embodiment of this application, step 400, comparing the first arrival times of all detectors with the same offset, and identifying detectors that do not meet preset requirements as detectors to be checked, includes:
[0081] See Figure 5 and Figure 6 For all geophones with the same offset distance relative to the same shot point, based on the first arrival time of the data received from the same shot by different geophones, if the error between the first arrival time difference and the actual time difference between any two geophones is greater than a first preset threshold, the two geophones are taken as geophones to be checked. The actual time difference is the ratio between the difference between the shot and the receiver distance and the surface velocity.
[0082] See Figure 7 For all geophones with the same shot-receiver distance relative to different shot points, if the error between the initial arrival time and the actual time of any geophone among all geophones is greater than the second preset threshold, the current geophone is taken as the geophone to be checked, where the actual time is the ratio between the shot-receiver distance and the ground velocity.
[0083] In the acquisition station crosstalk quantification quality control method of this application, crosstalk quality control of wired seismic instrument acquisition stations is achieved by sorting, displaying and comparing data acquired indoors. The receiver points to be verified are fed back to the field operator to arrange for line inspectors to conduct on-site inspection and verification. This method enables rapid quantification quality control of receiver point crosstalk. The method is simple to operate, highly accurate, and improves the accuracy of wired instrument acquisition data, laying a solid foundation for subsequent data processing.
[0084] The quantitative quality control method for data acquisition station cross-tracking proposed in this application is applied to a complex urban project constructed using 508XT wired instruments. The work area is characterized by complex obstacles, with a restricted ratio reaching 90% of the construction area. Due to the restrictions imposed by urban obstacles, there are many locations with open tracks and detours. Specific information is shown in Table 1 below.
[0085] Table 1
[0086] Instrument type 508XT Wired Inter-site cable length 30m Collection Station Type Single track, single station Detector distance 25m Receiver line spacing 100m Minimum lateral offset of the firing point 12.5m Total number of detector points 219028 Total detour (point) 2568 Always taking detours (roads) 11428
[0087] As seismic acquisition projects advance, exploration deployments are expanding into areas with complex surfaces, such as urban areas and oilfield core areas. Due to surface obstacles in these areas, wired instrument installation often involves numerous detours, such as... Figure 8As shown. Because the cable length between wired instrument acquisition stations is generally fixed—for example, in previous years when the channel spacing was typically 50m, the cable length was generally factory-set at 55m; as the channel spacing of detector points has decreased, the cable length in recent years is generally 30m, mainly suitable for observation systems with channel spacing less than 30m. When there are obstacles on the surface, the cable between two acquisition stations cannot correspond to adjacent detector points. Therefore, one or more intermediate acquisition stations need to be rerouted, meaning that the corresponding acquisition station will not appear in the acquired data. For example, if the cable length between acquisition stations is 30m, rerouting one intermediate acquisition station is equivalent to extending the cable to 60m; rerouting two intermediate acquisition stations is equivalent to extending the cable to 90m. This rerouting achieves the purpose of extending the cable.
[0088] When the seismic acquisition detectors are actually set up (generally marked along the line by measuring the station points using real-time dynamic carrier phase differential technology), for points that cannot be implemented at the theoretical design points (in subsequent line laying), offset selection will be carried out according to certain offset principles. If the offset still cannot obtain an implementable point, the corresponding detector point will be left empty. These points do not need to be equipped with detectors during line laying, and the corresponding acquisition station will be set as an empty channel by the operator before acquisition.
[0089] When the work area is affected by obstacles, adjacent detector points (see...) Figure 9a It is impossible to connect via a 30m cable; the eight intermediate data acquisition stations need to be rerouted (L2 reroutes to L1, then crosses the viaduct and returns to L2, a total distance of 200m); see [link / reference]. Figure 9b The area obstacles shown, L1 and L3, can be offset from the obstacles if the offset distance in the direction of the vertical detector line is no more than 75m. To ensure data uniformity and cable connection considerations, the offset detector points are required to increase at 45° increments. For example, to achieve an offset of 75m for a certain detector point, the detector points on both sides need to be offset accordingly. Specifically: point 1 offsets by 25m, point 2 by 50m, point 3 by 75m, point 4 by 50m, and point 5 by 25m; or the point offset increases at equal distances, such as point 1 by 5m, point 2 by 10m, point 3 by 15m, point 4 by 20m, point 5 by 15m, point 6 by 10m, and point 7 by 5m.
[0090] In all the above situations, detour settings are required. When a detector line has multiple detours, selecting one from each of the major and minor detector lines for station number verification or pulse testing, or selecting one from each unit for verification and arrangement, still poses a quality risk of undetected arrangement errors.
[0091] According to the method described in this application, such as Figure 5As shown, the receiving channels with the same offset distance for each shot were extracted for lateral first arrival time comparison. It should be noted that when the surface of the work area is undulating, data that has been subjected to static elevation correction was extracted to eliminate the influence of surface elevation on the first arrival time.
[0092] This application utilizes production data to check the arrangement and setup without increasing the workload of each stage in the field, avoiding the loopholes existing in traditional methods, directly improving the accuracy of collected data, and laying a solid foundation for subsequent high-precision data processing and interpretation.
[0093] It should be understood that although the steps in the flowchart are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order constraint on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the diagram may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the sub-steps or stages of other steps.
