[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0027] The detection method for detector performance provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0028] Figure 1 This is a flowchart illustrating the steps of a detector performance testing method provided in an embodiment of this application, as shown below. Figure 1 As shown, the method may include:

[0029] Step 101: Obtain shot gather data based on the shot data collected by the detectors at all receiver points.

[0030] In this embodiment of the application, shot gather data is obtained by collecting shot data from the detectors of all detectors, and thus gather data for each detector can be obtained based on the shot gather data.

[0031] It should be noted that seismic exploration is a method of artificially generating seismic waves (such as explosive explosions, controlled seismic sources, electric sparks, air guns, etc.) to cause vibrations in the Earth's crust, and using geophones to record the vibrations at various points on the ground caused by the reflected waves from the interfaces of various underground strata. By utilizing the different propagation patterns of seismic waves in different rocks, it is a method of exploring structures to find useful minerals.

[0032] In the process of seismic exploration, multiple shot points are usually set up, each shot point generates a vibration wave, and multiple geophones are set up around the shot points. Geophones are buried in the medium (i.e., the earth medium) at each geophone and the geophones are used to collect data from all shot points. The data of the shot points is the vibration wave data of that shot point.

[0033] Step 102: Obtain the gather data for each receiver point from the shot gather data.

[0034] The gather data is the collection of all shot points collected by the detector at the receiver point.

[0035] In this embodiment of the application, by obtaining the gather data of each receiver point from the shot gather data, the frequency amplitude set corresponding to each receiver point can be obtained based on the gather data of each receiver point.

[0036] Step 103: Based on each gather data, obtain the frequency amplitude set corresponding to each detector point.

[0037] The frequency amplitude set includes the frequency and amplitude of all vibration waves collected by the detector at each detector point within a preset time period; each shot point corresponds to one vibration wave.

[0038] In this embodiment of the application, by obtaining the frequency amplitude set corresponding to each detector point based on each gather data, the performance test result of the detector at each detector point can be obtained based on each frequency amplitude set.

[0039] It should be noted that the gather data is the collection of all shot points collected by the geophone at the receiver point during the entire acquisition period (i.e., the full time window), while the preset time period is a time segment (instant window) selected in advance from the entire acquisition period (i.e., the full time window).

[0040] Step 104: Based on each set of frequency amplitudes, obtain the detection results of the detector performance at each detector point.

[0041] In this embodiment of the application, the detection results of the detector performance at each detection point are obtained based on each frequency amplitude set, so as to evaluate the performance of the detector at each detection point.

[0042] In summary, in this embodiment, shot gather data is obtained by collecting shot data from the geophones of all geophones; gather data for each geophone is obtained from the shot gather data; gather data is a collection of all shot data collected by the geophones of the geophones at each geophone; frequency amplitude set corresponding to each geophone is obtained based on each gather data; frequency amplitude set includes the frequency and amplitude of all vibration waves collected by the geophones of each geophone within a preset time period; each shot corresponds to one vibration wave; and the performance test results of the geophones at each geophone are obtained based on each frequency amplitude set, thereby achieving the evaluation of geophone performance. This eliminates the need for manual analysis of seismic exploration data, improving work efficiency and solving the problem of low work efficiency caused by manual analysis of seismic exploration data to evaluate geophone performance in prior art.

[0043] Figure 2 This is a flowchart illustrating the specific steps of a detector performance testing method provided in an embodiment of this application, as shown below. Figure 2 As shown, the method may include:

[0044] Step 201: Obtain shot gather data based on the shot data collected by the detectors at all receiver points.

[0045] The implementation method of this step is similar to that of "Step 101" above, and will not be repeated here.

[0046] Optionally, in some embodiments, step 201 includes the following sub-steps (sub-step 2011, sub-step 2012):

[0047] Sub-step 2011: Obtain the original shot gather data based on the shot data collected by the detectors at all receiver points.

[0048] In this embodiment of the application, the original shot gather data is obtained based on the data of the shot points collected by the detectors of all the detectors, and then the original shot gather data is further processed to obtain the shot gather data.

[0049] Sub-step 2012: Perform static correction and noise reduction processing on the original shot gather data to obtain shot gather data.

[0050] In this embodiment of the application, in order to obtain the effective data of the shot points collected by the detectors of all receiver points, i.e., the shot gather data, it is necessary to perform static correction and noise reduction processing on the original shot gather data, so that the shot gather data can be further processed.

[0051] By executing sub-steps 2011 to 2012, shot gather data, which is considered valid data, can be obtained from the shot data collected by the detectors of all receivers, so as to obtain the gather data of each receiver based on the shot gather data.

[0052] Step 202: Obtain gather data for each receiver point from the shot gather data.

[0053] The gather data is the collection of all shot points collected by the detector at the receiver point.

[0054] The implementation method of this step is similar to that of "Step 102" above, and will not be repeated here.

[0055] Step 203: Based on each gather data, obtain the frequency amplitude set corresponding to each detector point.

[0056] The frequency amplitude set includes the frequency and amplitude of all vibration waves collected by the detector at each detector point within a preset time period; each shot point corresponds to one vibration wave.

[0057] The implementation method of this step is similar to that of "Step 103" above, and will not be repeated here.

[0058] Step 204: Based on each set of frequency amplitudes, obtain the detection results of the detector performance at each detector point.

[0059] The implementation method of this step is similar to that of "Step 104" above, and will not be repeated here.

[0060] Optionally, in some embodiments, step 204 includes the following sub-steps (sub-step 2041, sub-step 2042, sub-step 2043):

[0061] Sub-step 2041: Based on each set of frequency amplitudes, obtain the dominant frequency and bandwidth of the vibration wave collected by the detector at each detector point.

[0062] In this embodiment of the application, the dominant frequency and bandwidth of the vibration wave collected by the detector at each detector point are obtained according to each frequency amplitude set, so as to obtain the detection result of the performance of the detector at each detector point according to the dominant frequency and bandwidth of the vibration wave collected by the detector at each detector point.

[0063] Optionally, in some embodiments, sub-step 2041 includes the following sub-steps (step 2041a, step 2041b):

[0064] Step 2041a: Take the frequency corresponding to the largest amplitude in each set of frequency amplitudes as the main frequency of the vibration wave collected by the detector at each detector point.

[0065] In this embodiment of the application, by taking the frequency corresponding to the largest amplitude in each frequency amplitude set as the main frequency of the vibration wave collected by the detector at each detection point, the main frequency performance of the detector can be determined based on the magnitude of the main frequency.

[0066] Step 2041b: Based on the maximum and minimum frequencies in each set of frequency amplitudes, obtain the bandwidth of the vibration wave collected by the detector at each detector point.

[0067] In this embodiment of the application, the bandwidth of the vibration wave collected by the detector at each detection point is obtained based on the maximum and minimum frequencies in each frequency amplitude set, so as to determine the bandwidth performance of the detector based on the bandwidth range.

[0068] For example, if the largest frequency in the frequency amplitude set is 69 Hz and the smallest frequency is 51 Hz, then the bandwidth is 51 Hz to 69 Hz.

[0069] By executing steps 2041a to 2041b, the dominant frequency and bandwidth of the vibration wave collected by the detector at each detector point can be obtained. Based on each dominant frequency and bandwidth, the dominant frequency performance and bandwidth performance of the detector at each detector point can be further determined.

[0070] Sub-step 2042: Based on each of the main frequencies, obtain the detection results of the main frequency performance of the detector at each of the detection points.

[0071] In this embodiment of the application, the detection results of the main frequency performance of the detector at each detection point are obtained according to each main frequency, so as to evaluate the main frequency performance of the detector at each detection point.

[0072] It should be noted that the higher the main frequency acquired by the detector, the better the detector's main frequency performance. Optionally, a standard main frequency can be set. If the main frequency acquired by the detector is higher than the standard main frequency, the detector's main frequency performance is considered to be good.

[0073] Sub-step 2043: Based on each bandwidth, obtain the detection result of the bandwidth performance of the detector at each detection point.

[0074] In this embodiment of the application, the detection results of the bandwidth performance of the detector at each detection point are obtained according to each bandwidth, so as to evaluate the bandwidth performance of the detector at each detection point.

[0075] It should be noted that the larger the bandwidth range acquired by the detector, the wider the frequency range it can acquire, and thus the better its bandwidth performance. Optionally, a standard bandwidth can be set. If the bandwidth range acquired by the detector is within the standard bandwidth range, the test result of the detector's bandwidth performance is considered to be good.

[0076] By executing sub-steps 2041 to 2043, the performance test results of the detector at each detector point can be obtained based on the dominant frequency and bandwidth of the vibration wave collected by the detector at each detector point, so as to complete the evaluation of the dominant frequency performance and bandwidth performance of the detector at each detector point.

[0077] Optionally, in some embodiments, before step 204, the method further includes the following steps (steps 205 and 206):

[0078] Step 205: Based on the original shot gather data, obtain the noise amplitude set for each receiver point.

[0079] The noise amplitude set is the set of noise amplitudes of all shot points collected by the detector at the detector point within the preset time period.

[0080] In this embodiment of the application, a noise amplitude set for each receiver point is obtained based on the original shot gather data, so as to obtain the root mean square amplitude value of the noise at each receiver point based on the noise amplitude set of each receiver point.

[0081] Step 206: Obtain the root mean square amplitude value of the noise at each detector point based on each set of noise amplitudes.

[0082] In this embodiment of the application, the root mean square amplitude value of the noise at each detector point is obtained based on each noise amplitude set, so as to obtain specific information about the noise at each detector point.

[0083] It should be noted that the root mean square amplitude of the noise is the root mean square value of the amplitude of all shot point noises collected by the detector within a preset time period.

[0084] By executing steps 205 to 206, the root mean square amplitude value of the noise at each detector point can be obtained, and then the root mean square amplitude value of the noise can be further processed to obtain the detection result of the noise immunity performance of the detector.

[0085] Optionally, in some embodiments, step 204 includes the following sub-steps (sub-step 2044, sub-step 2045, sub-step 2046):

[0086] Sub-step 2044: Based on each set of frequency amplitudes, obtain the root mean square amplitude value of the vibration wave corresponding to each detector point.

[0087] In this embodiment of the application, the root mean square amplitude value of the vibration wave corresponding to each detector point is obtained according to each frequency amplitude set, so as to obtain the signal-to-noise ratio value of each detector point according to the root mean square amplitude value of the vibration wave corresponding to each detector point.

[0088] It should be noted that the root mean square amplitude of the vibration wave corresponding to the detector point is the root mean square value of the amplitude of all vibration waves collected by the detector at the detector point within a preset time period.

[0089] Sub-step 2045: Calculate the signal-to-noise ratio (SNR) of each detector point based on the root mean square amplitude of the noise and the root mean square amplitude of the vibration wave at each detector point.

[0090] In this embodiment of the application, the signal-to-noise ratio (SNR) value of each detector point is calculated based on the root mean square amplitude of the noise and the root mean square amplitude of the vibration wave at each detector point, so as to evaluate the noise immunity performance of the detector at each detector point based on the SNR value.

[0091] It should be noted that the signal-to-noise ratio of a detector point is the value obtained by dividing the root mean square amplitude of the vibration wave at that detector point by the root mean square amplitude of the noise at that detector point.

[0092] Sub-step 2046: Based on each signal-to-noise ratio value, obtain the detection result of the noise immunity performance of the detector at each detection point.

[0093] In this embodiment of the application, the noise immunity performance of the detector at each detection point is obtained based on the signal-to-noise ratio value, so as to evaluate the noise immunity performance of the detector at each detection point.

[0094] It should be noted that the higher the signal-to-noise ratio (SNR) value of the detector at the detection point, the better the noise immunity of the detector. Optionally, a standard SNR value can be set. If the SNR value of the detector is greater than the standard SNR value, the noise immunity test result of the detector is considered to be good.

[0095] By executing sub-steps 2044 to 2046, the signal-to-noise ratio (SNR) value for each detector point can be obtained, so that the noise immunity performance of the detector at each detector point can be evaluated based on the SNR value.

[0096] Optionally, in some embodiments, the method further includes the following steps (steps 207 and 208).

[0097] Step 207: Obtain the noise amplitude set for each detector point using a noise acquisition device.

[0098] The noise amplitude set is the set of noise amplitudes of all shot points collected by the detector at the detector point within the preset time period.

[0099] In this embodiment of the application, a noise amplitude set for each detector point is obtained through a noise acquisition device, so as to obtain the detection result of the noise immunity performance of the detector at each detector point based on the noise amplitude set of each detector point.

[0100] It should be noted that the noise acquisition equipment is wired to the detector to obtain the noise amplitude set at each detector point.

[0101] Step 208: Based on each set of noise amplitudes, obtain the detection results of the noise immunity performance of the detector at each detector point.

[0102] In this embodiment of the application, the noise immunity performance of the detector at each detection point is obtained based on each noise amplitude set, so as to evaluate the noise immunity performance of the detector at each detection point.

[0103] Specifically, in some embodiments, based on the noise amplitude set of each detector, the root mean square (RMS) amplitude value of the noise at each detector point can be obtained. Based on the RMS amplitude value of the noise at each detector point, the noise immunity performance test result of the detector at each detector point can be obtained. Specifically, the smaller the RMS amplitude value of the noise obtained by the detector, the better the noise immunity performance of the detector. Optionally, a standard RMS amplitude value for the noise can be set. If the RMS amplitude value of the noise obtained by the detector is less than the standard RMS amplitude value, the noise immunity performance test result of the detector is considered to be good.

[0104] By executing steps 207 to 208, the noise amplitude set of each detector point can be obtained through the noise acquisition device, and the noise immunity performance of the detector at each detector point can be evaluated based on the noise amplitude set of each detector point.

[0105] Optionally, in some embodiments, the detector is embedded in the medium at the detection point by burying the detector housing and tail cone in the medium.

[0106] In prior art, the detector is embedded in the medium at the detection point by burying the detector's tail cone in the medium, while the detector's housing is exposed outside the medium (i.e., above the ground). In the embodiments of this application, the detector is embedded in the medium at the detection point by burying both the detector's housing and tail cone in the medium.

[0107] In a noise immunity test, detector A and detector B were set up at the same detector point. Data from 6000 shot points were collected at this detector point. Detector A was buried in the medium at this detector point by embedding both the detector housing and the tail cone in the medium. Detector B was buried in the medium at this detector point by embedding the tail cone in the medium, while the detector housing was exposed outside the medium. The signal-to-noise ratio (SNR) value A1 for all vibration waves collected by detector A in the frequency range of 10 Hz to 20 Hz is 1.28, and the SNR value B1 for all vibration waves collected by detector B in the same frequency range is 1.2. The SNR value A2 for all vibration waves collected by detector A in the frequency range of 60 Hz to 120 Hz is 1.01, and the SNR value B2 for all vibration waves collected by detector B in the same frequency range is 0.98. Since the SNR value A1 is greater than the SNR value B1, and the SNR value A2 is greater than the SNR value B2, it indicates that compared with the prior art, the detector of this application has a larger SNR value in the frequency range of 10 Hz to 20 Hz and the frequency range of 60 Hz to 120 Hz, and thus better noise immunity.

[0108] In this context, the signal-to-noise ratio (SNR) value A1 corresponding to all vibration waves in the frequency range of 10 Hz to 20 Hz collected by detector A is obtained by dividing the root mean square amplitude (RMS) of the amplitude of all vibration waves in the frequency range of 10 Hz to 20 Hz collected by detector A by the RMS amplitude (RMS) of the amplitude of the noise corresponding to all vibration waves in the frequency range of 10 Hz to 20 Hz collected by detector A by detector A. Similarly, the methods for obtaining the SNR values ​​B1, A2, and B2 are similar to those for obtaining the SNR value A1, and will not be repeated here.

[0109] In another noise immunity test, there were 32 detector points and 6000 shot points. Two types of detectors were set up at each detector point, namely detector A and detector B. Detector A was buried in the medium at the detector point by burying both the detector housing and the tail cone in the medium. Detector B was buried in the medium at the detector point by burying only the tail cone of the detector in the medium. The two types of detectors at each detector point collected data from the 6000 shot points respectively.

[0110] Reference Figure 3The vertical axis represents the percentage of negative noise differences, and the horizontal axis represents the detector point numbers (32 detector points in total, from 1611 to 1642). The percentage of negative noise differences is calculated by dividing the number of shot points with negative noise differences by the total number of shot points. Each shot point corresponds to one noise difference, which is the amplitude of the noise at a shot point acquired by detector A minus the amplitude of the noise at that shot point acquired by detector B. A negative noise difference indicates that the amplitude of the noise at that shot point acquired by detector A is higher than that acquired by detector B. The noise amplitude collected by detector B at this shot point is smaller, meaning that detector A has better noise immunity than detector B at this shot point. The more shot points with negative noise differences, i.e., the larger the proportion of negative differences, the more shot points detector A has better noise immunity than detector B. If the number of shot points with better noise immunity than detector B exceeds 50% of the total number of shot points, i.e., the proportion of negative differences is greater than 50%, it means that detector A has better noise immunity than detector B.

[0111] exist Figure 3 In the study, there were 20 detector points with a negative difference ratio greater than 50%. Since detector A had better noise immunity than detector B for 62.5% (20 / 32 = 62.5%) of the detector points, statistically speaking, detector A had better noise immunity than detector B.

[0112] In this embodiment of the application, by burying the detector housing and tail cone in the medium to collect data from all shot points of the detector, the detector has better noise immunity compared to prior art.

[0113] In summary, in this embodiment, shot gather data is obtained by collecting shot data from the geophones of all geophones; gather data for each geophone is obtained from the shot gather data; gather data is a collection of all shot data collected by the geophones of the geophones at each geophone; frequency amplitude set corresponding to each geophone is obtained based on each gather data; frequency amplitude set includes the frequency and amplitude of all vibration waves collected by the geophones of each geophone within a preset time period; each shot corresponds to one vibration wave; and the performance test results of the geophones at each geophone are obtained based on each frequency amplitude set, thereby achieving the evaluation of geophone performance. This eliminates the need for manual analysis of seismic exploration data, improving work efficiency and solving the problem of low work efficiency caused by manual analysis of seismic exploration data to evaluate geophone performance in prior art.
