Environmentally friendly, safe, and efficient controllable seismic sources have become an important excitation method in oil and gas exploration. The impact of abnormal amplitude noise near the excitation point on the effective wave from a controllable seismic source is much greater than that from an explosive source.
[0003] Currently, noise generated by controlled vibration sources is generally removed as interference waves with abnormally high amplitude.
[0004] However, the qualitative analysis of the characteristics of controlled-source mechanical vibration noise as a short-phase axis distribution with strong amplitude has not yet been carried out, resulting in low accuracy in identifying controlled-source mechanical vibration noise.

[0056] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
[0057] Reference Figure 1 , Figure 1 A flowchart illustrating the steps of a controllable vibration source mechanical vibration noise identification method provided by an embodiment of the present invention is shown. Figure 1 As shown, the method for identifying mechanical vibration noise from a controllable vibration source may include the following steps:
[0058] Step S110: Obtain the original noise waveform data of the controllable vibration source under at least one mechanical vibration state through a preset detector arrangement.
[0059] The detector array comprises multiple detectors arranged in a preset manner, and these detectors are used to receive waveform data. In this embodiment of the invention, the detector array is a waveform data acquisition array formed by multiple detectors arranged in a preset manner, used to acquire waveform data corresponding to different states of the controllable vibration source in real time. Specifically, when the controllable vibration source is in a mechanical vibration state, the original noise waveform data corresponding to this mechanical vibration state can be acquired through the preset detector array.
[0060] A detector is an observation device used to receive waveform data. In a detector array, different detectors are positioned differently. In a detector array, one detector represents one channel, and different detectors represent different channels. The distance between channels is called the receiving channel distance, and the distance between different detectors and the controllable seismic source is called the shot-receiver distance. For example, a detector array may include 120 channels, meaning it contains 120 detectors arranged in a preset pattern.
[0061] In this embodiment of the invention, the controllable seismic source is a mechanical seismic source. The working method of the controllable seismic source is as follows: seismic waves are generated by continuously impacting the ground with a vibrator installed on a special vehicle. The continuous time and frequency variation range of the vibrator can be controlled manually.
[0062] The mechanical vibration state is a mechanical vibration state other than the excitation state of the controllable vibration source. For example, the mechanical vibration state may include at least one of the controllable vibration source walking state, controllable vibration source pressurization state, and controllable vibration source activation state.
[0063] The raw noise waveform data consists of waveforms acquired by a pre-defined array of detectors when the controllable source is in a specific mechanical vibration state. Since the mechanical vibration state of the controllable source is its unexcited state, the waveform data acquired by the detector array at this time represents the raw noise waveform data generated by the controllable source under this mechanical vibration state. It should be noted that the raw noise waveform data does not include the effective wave data generated during the excitation of the controllable source.
[0064] In this embodiment of the invention, the mechanical vibration state of the controllable vibration source can include one type. Specifically, when the controllable vibration source is in the mechanical vibration state, a raw noise waveform data corresponding to the mechanical vibration state can be obtained through a preset detector arrangement. The mechanical vibration state of the controllable vibration source can also include multiple types. For example, the mechanical vibration state includes a first mechanical vibration state and a second mechanical vibration state. When the controllable vibration source is in the first mechanical vibration state, a raw noise waveform data corresponding to the first mechanical vibration state can be obtained through a preset detector arrangement. When the controllable vibration source is in the second mechanical vibration state, another raw noise waveform data corresponding to the second mechanical vibration state can be obtained through a preset detector arrangement.
[0065] Step S120: Obtain the original working waveform data of the controllable source under the excitation state and preset scan length through the detector arrangement.
[0066] Among them, the excitation state of the controllable seismic source is the state in which the controllable seismic source works according to the construction parameters, which may include, but are not limited to, scanning length, scanning frequency, output power, etc.
[0067] Specifically, the scan length is the duration of regular vibrations transmitted to the earth by a controllable seismic source within a controllable frequency range. In this embodiment of the invention, the preset scan length can be determined based on the scan length to be used in the work area. The preset scan length may include one pre-set scan length or multiple pre-set different scan lengths. For example, if the scan length to be used in the work area is 16s (time unit: seconds), when the number of preset scan lengths is 1, the scan length to be used in the work area can be determined as 16s; when the number of preset scan lengths is 5, the scan length to be used in the work area can be included and extended in both shortening and lengthening directions. The five different preset scan lengths can specifically be 8s, 12s, 16s, 20s, and 28s. This embodiment of the invention does not impose specific limitations on this.
[0068] The scanning frequency is a range of vibration frequencies adapted to ground propagation, determined based on the geological characteristics of the survey point. The scanning frequency includes a starting frequency and a ending frequency. For example, the scanning frequency can be 1.5Hz-84Hz (frequency unit: Hertz), 2Hz-72Hz, 2Hz-64Hz, 1.5Hz-124Hz, etc. Specifically, the controllable seismic source can uniformly change from the starting frequency to the ending frequency within the scanning length. The controllable seismic source can use linear frequency increase, power-law frequency increase, or exponential frequency increase to uniformly change from the starting frequency to the ending frequency within the scanning length; of course, the controllable seismic source can also use linear frequency decrease to uniformly change from the starting frequency to the ending frequency within the scanning length, but this embodiment of the invention does not specifically limit this.
[0069] The output power is determined based on the weight of the controllable seismic source and the geological characteristics of the survey point. A higher output power results in greater seismic energy transmitted to the ground through the controllable seismic source. It should be noted that the output power of the controllable seismic source can be between 30% and 80% of its maximum output power, selected based on the characteristics of previous seismic data from the survey point.
[0070] In this embodiment of the invention, when the controllable seismic source is in the excitation state, the original working waveform data corresponding to the preset scan length can be obtained through a preset detector arrangement. Since the excitation state of the controllable seismic source is the state in which the controllable seismic source operates according to the construction parameters, the waveform data obtained by the detector arrangement at this time is the original working waveform data generated by the controllable seismic source in the excitation state corresponding to the construction parameters. This original working waveform data includes the original interference wave data and the original effective wave data generated in the excitation state of the controllable seismic source.
[0071] When the number of preset scan lengths is 1, "controlled source in excitation state and at preset scan length" refers to the state in which the controlled source operates according to the preset scan length. At this time, a type of raw working waveform data corresponding to the preset scan length can be obtained through the detector arrangement. When the number of preset scan lengths is 3, such as a first preset scan length, a second preset scan length, and a third preset scan length, "controlled source in excitation state and at first preset scan length" refers to the state in which the controlled source operates according to the first preset scan length. At this time, a type of raw working waveform data corresponding to the first preset scan length can be obtained through the detector arrangement. "Controlled source in excitation state and at second preset scan length" refers to the state in which the controlled source operates according to the second preset scan length. At this time, another type of raw working waveform data corresponding to the second preset scan length can be obtained through the detector arrangement. "Controlled source in excitation state and at third preset scan length" refers to the state in which the controlled source operates according to the third preset scan length. At this time, yet another type of raw working waveform data corresponding to the third preset scan length can be obtained through the detector arrangement.
[0072] It should be noted that when the preset scan length includes one scan length, the scan length in the construction parameters corresponding to the controllable source excitation state is the preset scan length, and other parameters in the construction parameters can be the same as or similar to the construction parameters to be used in the work area; when the preset scan length includes multiple different scan lengths, the construction parameters corresponding to the controllable source excitation state remain the same except for the different scan lengths.
[0073] Step S130: Preprocess the original noise waveform data and the original working waveform data respectively to obtain noise waveform data and working waveform data.
[0074] In this embodiment of the invention, the preprocessing of the original noise waveform data and the original working waveform data specifically involves: correlating the original noise waveform data with the first design scan signal corresponding to the construction parameters to be used in the work area to obtain the correlated waveform data as noise waveform data; and correlating the original working waveform data with the second design scan signal corresponding to the preset scan length to obtain the correlated waveform data as working waveform data.
[0075] It should be noted that when the scanning length in the construction parameters to be used in the work area is the same as the preset scanning length, the first design scanning signal and the second design scanning signal can be the same; when the preset scanning length includes multiple different scanning lengths, the second design scanning signal corresponding to the different original working waveform data of the controllable source obtained by the detector arrangement under the excitation state and different preset scanning lengths is different.
[0076] Step S140: Identify the noise characteristics corresponding to the mechanical vibration state based on the noise waveform data.
[0077] The noise characteristics include, but are not limited to, noise propagation speed, noise frequency distribution, and noise energy distribution. In this embodiment of the invention, the noise waveform data corresponding to different mechanical vibration states may be different, and the noise characteristics identified for different mechanical vibration states based on the noise waveform data corresponding to different mechanical vibration states may also be different, or they may be the same.
[0078] In this embodiment of the invention, noise waveform data corresponding to a mechanical vibration state can be loaded into scrambling data processing software, and the spectral data of the noise waveform data can be calculated using the scrambling data processing software. Then, the noise frequency distribution corresponding to the mechanical vibration state can be determined based on the spectral data. When there are multiple mechanical vibration states, noise wave data corresponding to different mechanical vibration states can be sequentially loaded into the scrambling data processing software for calculation and analysis to obtain the noise frequency distribution corresponding to different mechanical vibration states. Alternatively, noise wave data corresponding to different mechanical vibration states can be simultaneously loaded into the scrambling data processing software for calculation and analysis to obtain comparative data on the noise frequency distribution corresponding to different mechanical vibration states.
[0079] Furthermore, noise waveform data corresponding to the mechanical vibration state can be loaded into scrambling data processing software. The software can then calculate the root mean square amplitude of the noise waveform data acquired by each channel in the detector array. Next, by combining the distance between each channel and the controllable source, a noise-distance curve is obtained, and the noise energy distribution corresponding to the mechanical vibration state is determined based on this curve. When there are multiple mechanical vibration states, noise wave data corresponding to different mechanical vibration states can be sequentially loaded into the scrambling data processing software for calculation and analysis to obtain the noise energy distribution corresponding to different mechanical vibration states. Alternatively, noise wave data corresponding to different mechanical vibration states can be loaded into the scrambling data processing software simultaneously for calculation and analysis to obtain comparative data on the noise energy distribution corresponding to different mechanical vibration states.
[0080] It should be noted that the perturbation data processing software can be geophysical software, such as Kron data analysis software.
[0081] Step S150: Based on the working waveform data, identify the resonant interference wave characteristics of the controllable vibration source in the excitation state.
[0082] The characteristics of the resonant interference wave include, but are not limited to, the frequency, energy, and occurrence time of the resonant interference wave. Specifically, the energy of the resonant interference wave can be determined first based on the working waveform data. Then, based on the energy, the recording time corresponding to the strong energy cluster can be determined, and this recording time can be identified as the occurrence time of the resonant interference wave. In addition, the location of the strong energy cluster can be determined based on the energy, and a spectral analysis can be performed on the location to determine the frequency corresponding to that location, which can then be identified as the frequency of the resonant interference wave.
[0083] In this embodiment of the invention, the working waveform data can be analyzed using scrambling data processing software to determine the energy of the resonant interference wave, the occurrence time of the resonant interference wave, and the frequency of the resonant interference wave.
[0084] It should be noted that after identifying the noise characteristics corresponding to the mechanical vibration state in step S140 and the resonant interference wave characteristics of the controllable source in the excitation state in step S150, Fourier transform can be performed based on the noise characteristics and resonant wave characteristics to obtain the amplitude spectrum and phase spectrum including the black triangle region of the controllable source. The spatial location of the mechanical noise of the controllable source is determined based on the amplitude spectrum and phase spectrum. When suppressing noise, a reasonable noise suppression spatial range can be selected based on the spatial location of the noise. Furthermore, the occurrence time of the resonant interference wave generated when the interference wave and the effective wave resonate in the excitation state of the controllable source is determined based on the amplitude spectrum and phase spectrum. A reasonable scanning length is determined to control the occurrence time of the resonant interference wave to be greater than the time when the effective wave is generated in the target layer, thereby reducing the interference of the resonant interference wave on the effective wave corresponding to the target layer. In addition, the frequency distribution of the mechanical vibration noise generated by the controllable source can be determined based on the amplitude spectrum and phase spectrum. Noise suppression is performed only on the working waveform within the frequency range corresponding to the mechanical vibration noise, protecting the working waveform outside the frequency range corresponding to the mechanical vibration noise from damage by noise suppression measures, thereby ensuring the fidelity of the effective wave in the working waveform. Optionally, the preset arrangement includes the receiving channel spacing between the detectors; the method may further include the following steps:
[0085] Step A11: Determine the dip angle of the strata at the survey point where the detector array is located.
[0086] The receiving channel distance is the distance between adjacent detectors in a preset direction, specifically the distance between each detector in the detector array and its adjacent detectors. It should be noted that adjacent detectors refer to detectors that are adjacent to each other in the preset direction.
[0087] In this embodiment of the invention, the preset direction can be the direction of outward radiation centered on the controllable seismic source.
[0088] Furthermore, the survey points are areas within the target work area where raw noise waveform data and raw working waveform data need to be acquired, and the detectors are arranged within these survey points. The survey points can be representative areas within the target work area with relatively flat terrain.
[0089] The dip angle is the tilt angle of the current survey point relative to the horizon. In this embodiment of the invention, when the actual dip angle of the survey point is greater than 30°, the dip angle of the survey point where the detector array is located, determined in step A11, is equal to the actual dip angle; when the actual dip angle of the survey point is less than or equal to 30°, the dip angle of the survey point where the detector array is located, determined in step A11, is equal to 30°.
[0090] Step A12: Obtain the estimated propagation speed of the mechanical vibration noise from the controllable source.
[0091] It should be noted that at the survey point where the detectors are arranged, the propagation speed of noise can be estimated in advance based on experience or by consulting relevant data, so as to obtain the estimated propagation speed of mechanical vibration noise from the controllable source.
[0092] For example, at survey point A where the detector array is located, the estimated propagation speed of the controlled source mechanical vibration noise is estimated to be 800 m / s (unit: meters per second) based on experience or by consulting relevant data. This estimated propagation speed of 800 m / s is used to determine the receiving channel distance in step A14. However, the noise propagation speed in the noise characteristics corresponding to the mechanical vibration state identified in step S140 is a more accurate speed value than the estimated propagation speed. The noise propagation speed in the noise characteristics corresponding to the mechanical vibration state identified in step S140 can be 834 m / s.
[0093] Step A13: Obtain the maximum value of the scanning frequency corresponding to the controllable seismic source.
[0094] The maximum scanning frequency corresponding to the controllable seismic source is the maximum scanning frequency in the construction parameters when the controllable seismic source is in the excitation state corresponding to the construction parameters. For example, when the scanning frequency is 1.5Hz-84Hz, the maximum scanning frequency corresponding to the controllable seismic source is 84Hz; when the scanning frequency is 2Hz-72Hz, the maximum scanning frequency corresponding to the controllable seismic source is 72Hz.
[0095] Step A14: Determine the receiving channel distance based on the stratum dip angle, the estimated propagation velocity, and the maximum value of the scanning frequency.
[0096] In this embodiment of the invention, the receiving channel distance is determined based on the dip angle of the stratum at the survey point where the detector array is located, as determined in step A11; the estimated propagation velocity of the mechanical vibration noise of the controllable source, as estimated in step A12; and the maximum value of the scanning frequency corresponding to the controllable source, as obtained in step A13. Specifically:
[0097] Based on the stratum dip angle, estimated propagation velocity, and maximum scanning frequency, the receiver spacing is determined using the following formula 1:
[0098]
[0099] Where Δx represents the receiver distance in meters (m); v represents the estimated propagation speed in meters per second (m / s); and f represents the estimated propagation speed in seconds (m / s). max The maximum scanning frequency is represented by Hz; θ represents the dip angle of the formation, in degrees.
[0100] As can be seen from Formula 1, when the stratum dip angle is small, a fixed value of 30° is taken, and the maximum scanning frequency is constant, the receiver spacing is directly proportional to the estimated propagation velocity; the smaller the estimated propagation velocity, the smaller the required receiver spacing. Therefore, the selection of the receiver spacing depends on the minimum estimated propagation velocity. Thus, in this embodiment of the invention, the receiver spacing can be less than or equal to... It is determined within the range.
[0101] When the maximum scanning frequency corresponding to the controllable seismic source is 84Hz, the surface undulation at the survey point is small, and the stratum dip angle is less than 30°, the receiving channel distance corresponding to the estimated propagation speed of mechanical vibration noise from different controllable seismic sources is shown in Table 1. Table 1 shows a table of receiving channel distances corresponding to the estimated propagation speed of mechanical vibration noise from different controllable seismic sources provided by an embodiment of the present invention.
[0102] Interference wave velocity (m / s) 350 400 500 600 800 1000 1500 Receiving channel distance (m) 4 5 6 7 10 12 18
[0103] Table 1
[0104] Optionally, the detector arrangement includes detectors arranged in a star pattern; the detectors in the detector arrangement are arranged in a star pattern with the controllable seismic source as the center, according to the receiving channel spacing.
[0105] In this embodiment of the invention, the detectors in the detector array are arranged in a star-shaped pattern with the controllable seismic source as the center, so as to acquire waveform data of the controllable seismic source from different directions.
[0106] It should be noted that, depending on the actual needs of waveform data acquisition, the detectors in the detector array can be arranged in a cross shape, and this embodiment of the invention does not specifically limit this arrangement.
[0107] In addition, the detector arrangement may also include a length parameter, which is the maximum distance between the detectors set in the preset direction and the controllable seismic source. The length parameter of the detector arrangement can be determined according to the influence range of the mechanical vibration noise of the controllable seismic source. To ensure that the receiving range of the detector arrangement is greater than the influence range of the mechanical vibration noise, the length parameter of the detector arrangement can be in the range of 2000m-3000m.
[0108] Reference Figure 2 , Figure 2 A schematic diagram of a detector arrangement provided by an embodiment of the present invention is shown. Figure 2 As shown, the detectors are arranged in a star-shaped pattern with the controllable seismic source as the center. The receiver channel spacing between the detectors is 3m, and the length parameter of the detector array is set to 2400m.
[0109] Optionally, step S110, which involves acquiring the raw noise waveform data of a controllable vibration source under at least one mechanical vibration state through a preset detector arrangement, may include the following steps:
[0110] Step S111: Under the controllable seismic source travel state, the first original noise waveform data corresponding to the controllable seismic source travel state is obtained through a preset detector arrangement.
[0111] Step S112: Under the controlled source pressurization state, the second original noise waveform data corresponding to the controlled source pressurization state is obtained through a preset detector arrangement.
[0112] Step S113: Under the controllable vibration source activation state, the third original noise waveform data corresponding to the controllable vibration source activation state is obtained through a preset detector arrangement.
[0113] The mechanical vibration states include the controllable vibration source walking state, the controllable vibration source boosting state, and the controllable vibration source activation state; the original noise waveform data includes the first original noise waveform data corresponding to the controllable vibration source walking state, the second original noise waveform data corresponding to the controllable vibration source boosting state, and the third original noise waveform data corresponding to the controllable vibration source activation state.
[0114] Specifically, the controlled source traveling state refers to the state in which the controlled source moves. It should be noted that the traveling speed of the controlled source is very small, and the distance traveled in the traveling state is negligible relative to the scale of the detector array. It can be considered that the controlled source is still in the center position of the detector array. The controlled source pressurization state refers to the state corresponding to the process of the controlled source moving to the preset position and ending the traveling state, and then lowering the vibrating plate to the ground through pressurization. The controlled source activation state refers to the state in which the engine is started after the controlled source ends the pressurization state, but the controlled source has not yet entered the excitation state according to the construction parameters.
[0115] In this embodiment of the invention, when the mechanical vibration state includes a controllable vibration source walking state, a controllable vibration source boosting state, and a controllable vibration source activation state, when the controllable vibration source is in the controllable vibration source walking state, a first original noise waveform data corresponding to the controllable vibration source walking state can be obtained through a preset detector arrangement; when the controllable vibration source is in the controllable vibration source boosting state, a second original noise waveform data corresponding to the controllable vibration source walking state can be obtained through a preset detector arrangement; and when the controllable vibration source is in the controllable vibration source activation state, a third original noise waveform data corresponding to the controllable vibration source walking state can be obtained through a preset detector arrangement.
[0116] Optionally, step S120, which involves acquiring the original working waveform data of the controllable source under the excitation state and a preset scan length through the detector arrangement, may include the following steps:
[0117] Step S121: When the controllable vibration source is in the excitation state, acquire the original working sub-waveform data corresponding to different preset sub-scan lengths.
[0118] The preset scan length includes at least one different preset sub-scan length; the original working waveform data includes original working sub-waveform data corresponding to different preset sub-scan lengths.
[0119] In this embodiment of the invention, the preset scan length may include at least one different preset sub-scan length. When the preset scan length includes one preset sub-scan length, and the controllable seismic source is in the excitation state, the scan length corresponding to the excitation state is the preset sub-scan length. The original working sub-waveform data corresponding to this sub-scan length can be acquired through detector arrangement, and at this time, the original working sub-waveform data is the same as the preset sub-waveform data. When the preset scan length includes multiple preset sub-scan lengths, different construction parameters corresponding to different sub-scan lengths can be preset, and then the controllable seismic source can be made to enter the excitation state according to different construction parameters. Different original working sub-waveform data corresponding to different sub-scan lengths can be acquired through detector arrangement, and at this time, the original working sub-waveform data includes different original working sub-waveform data corresponding to different sub-scan lengths.
[0120] Optionally, the noise characteristics include noise propagation speed, and step S140, which identifies the noise characteristics corresponding to the mechanical vibration state based on the noise waveform data, may include the following steps:
[0121] Step S141: Based on the noise waveform data, determine the first position and the second position corresponding to the in-phase axis in the noise waveform data.
[0122] Step S142: Obtain the first channel number and the second channel number corresponding to the first position and the second position, respectively.
[0123] Step S143: When the first position and the second position are in phase, obtain the first time corresponding to the first position and the second time corresponding to the second position.
[0124] Step S144: Determine the noise propagation speed corresponding to the target mechanical vibration state based on the first difference between the first channel number and the second channel number, the second difference between the first time and the second time, and the receiving channel distance.
[0125] It should be noted that the in-phase axis is the line connecting the extreme values (e.g., peaks or troughs) of vibration phase in each channel of the noise waveform data. The first position and the second position are the detector positions corresponding to the in-phase axis. Based on the first and second positions corresponding to the in-phase axis, the first channel number corresponding to the first position and the second channel number corresponding to the second position can be obtained. Here, the first channel number is the number of the channel where the detector is located at the first position, and similarly, the second channel number is the number of the channel where the detector is located at the second position.
[0126] In this array, different detectors correspond to different channel numbers. These channel numbers are set based on the distance between the detector and the controlled seismic source, and they visually reflect the distance relationship between the detector and the controlled seismic source. Specifically, channel numbers can be set in progressively increasing order based on the relationship between the distance between the detector and the controlled seismic source, from smallest to largest.
[0127] In this embodiment of the invention, the noise characteristics may include the noise propagation speed. Determining the noise propagation speed based on noise waveform data specifically involves: determining the positions of the in-phase axes in the noise waveform data: a first position and a second position; then, based on the first and second positions, obtaining the first channel number corresponding to the first position and the second channel number corresponding to the second position, respectively; subsequently, based on the first and second positions, determining the first time and the second time when the first and second positions are in phase; finally, based on the first difference between the first and second channel numbers, the second difference between the first and second times, and the receiving channel distance, determining the noise propagation speed corresponding to the mechanical vibration state using Formula 2.
[0128]
[0129] Among them, v n R1 represents the noise propagation speed; R2 represents the second channel number; R1 represents the first channel number; Δx represents the receiving channel distance; t2 represents the second time; t1 represents the first time.
[0130] In this embodiment of the invention, the noise characteristics may further include the noise frequency distribution and the noise energy distribution. For details on how the noise frequency distribution and noise energy distribution are determined, please refer to the relevant description of step S140, which will not be repeated here.
[0131] Optionally, step S150, which involves identifying the resonant interference wave characteristics of the controllable vibration source in the excitation state based on the working waveform data, may include the following steps:
[0132] Step S151: Based on the working waveform data, determine at least one of the following: resonant interference wave frequency, resonant interference wave energy, and resonant interference wave occurrence time.
[0133] In this embodiment of the invention, the working waveform data can be analyzed using scrambling data processing software to determine the energy of the resonant interference wave, the occurrence time of the resonant interference wave, and the frequency of the resonant interference wave.
[0134] Specifically, the energy of the resonant interference wave can be determined first based on the working waveform data. Then, based on the energy of the resonant interference wave, the recording time corresponding to the strong energy cluster can be determined, and this recording time can be determined as the occurrence time of the resonant interference wave. In addition, the location of the strong energy cluster can be determined based on the energy of the resonant interference wave, and the frequency corresponding to the location of the strong energy cluster can be determined by performing spectral analysis, and this frequency can be determined as the frequency of the resonant interference wave.
[0135] For example, the above-mentioned controllable source mechanical vibration noise identification method is applied to the southwestern Tarim Basin piedmont area, where the surface is a relatively flat Gobi gravel area, the low velocity drop layer is a continuous medium, and the low velocity drop zone is very thick. In actual production, a controllable source is used for excitation.
[0136] Specifically, the controllable vibration source mechanical vibration noise identification method provided by the embodiments of the present invention first acquires the original noise waveform data of the controllable vibration source under at least one mechanical vibration state through a preset detector arrangement; then, it acquires the original working waveform data of the controllable vibration source under the excitation state and a preset scan length through the detector arrangement; then, it preprocesses the original noise waveform data and the original working waveform data respectively to obtain noise waveform data and working waveform data; finally, it identifies the noise characteristics corresponding to the mechanical vibration state based on the noise waveform data, and identifies the resonant interference wave characteristics of the controllable vibration source under the excitation state based on the working waveform data.
[0137] In this embodiment of the invention, the mechanical vibration states include a controllable source walking state, a controllable source pressurization state, and a controllable source activation state. A total of three test shots were designed corresponding to different mechanical vibration states, thereby obtaining the original noise waveform data corresponding to each state. Furthermore, considering that the scanning length used in this construction area is 16 seconds, five preset scanning lengths were designed, including 8 seconds, 12 seconds, 16 seconds, 20 seconds, and 28 seconds, thereby obtaining the original working waveform data corresponding to different preset scanning lengths.
[0138] After preprocessing the original noise waveform data and the original working waveform data through step S130 to obtain the noise waveform data and the working waveform data, the noise propagation velocity corresponding to different mechanical vibration states of the controllable source is first determined according to steps S141 to S144, as shown in Table 2. Table 2 shows the noise propagation velocity corresponding to different mechanical vibration states of a controllable source provided by an embodiment of the present invention.
[0139]
[0140] Table 2
[0141] As shown in Table 2, the noise propagation speed of the controllable source under different mechanical vibration states is basically the same, all around 540m / s.
[0142] Furthermore, the noise waveform data is loaded into scrambling data processing software to calculate the spectral data of the noise waveform data, thereby determining the noise frequency distribution corresponding to the mechanical vibration state based on the spectral data. (Refer to...) Figure 3 , Figure 3 This diagram illustrates the spectrum of noise waveform data from a controllable vibration source under different mechanical vibration states, according to an embodiment of the present invention. Figure 3 As shown, the noise wave data corresponding to different mechanical vibration states were loaded into the scrambling data processing software for calculation and analysis. The results showed that the noise frequency distribution corresponding to different mechanical vibration states was around 30Hz.
[0143] Furthermore, the noise waveform data corresponding to the mechanical vibration state is loaded into the scrambling data processing software. The software calculates the root mean square amplitude of the noise waveform data acquired by each channel in the detector array. Then, combining the distance between each channel and the controllable source, a curve showing the noise variation with distance is obtained. Based on this curve, the noise energy distribution corresponding to the mechanical vibration state is determined. (Refer to...) Figure 4 , Figure 4 This diagram illustrates the noise energy distribution of a controllable vibration source under different mechanical vibration states, according to an embodiment of the present invention. Figure 4 As shown, overall, the noise energy is relatively strong in both the controlled source activation state and the controlled source travel state. Within a radius of 250m, the noise energy is relatively strong in the controlled source activation state; within a radius of 250m to 750m, the noise energy is relatively strong in the controlled source travel state; outside a radius of 750m, under different mechanical vibration states, the noise energy decreases to the ambient noise level, meaning that the noise interference range of the controlled source under different mechanical vibration states is within a radius of 750m.
[0144] In this embodiment of the invention, step S151 determines the frequency, energy, and occurrence time of the resonant interference wave based on the working waveform data. (Specific reference is needed for this step.) Figure 5 , Figure 5 This diagram illustrates a resonant interference wave from a controllable vibration source in an excited state, according to an embodiment of the present invention. Figure 5As shown, different working waveform data corresponding to different preset scan lengths of the controllable seismic source reveal a strong energy cluster near the shot point. This strong energy cluster is located in the middle of the detector's recording time, and its appearance time varies across different preset scan lengths. Energy analysis was performed on the strong energy cluster, along with three windows (above and below it). The analysis shows that the energy of the strong energy cluster is greater than both the window below and below it. Spectral analysis of this strong energy cluster region reveals that its energy is mainly concentrated at 30Hz, similar to the noise energy distribution at 30Hz under the mechanical vibration state of the controllable seismic source.
[0145] As shown in Table 3, Table 3 shows a comparison of the occurrence time of resonant interference waves corresponding to the working waveform data of a controllable vibration source under different preset scan lengths provided in the embodiments of the present invention.
[0146]
[0147] Table 3
[0148] The scanning frequencies corresponding to different preset scan lengths range from 2Hz to 84Hz. Table 3 shows the time required to reach 30Hz. As the scan length increases, the time to reach 30Hz gradually increases, and the time for the strong energy cluster to appear on a single shot also increases accordingly, showing a clear correlation between the two. Therefore, it can be considered that the mechanical vibration noise of the controllable source and the design scan signal are correlated and reinforced near 30Hz, generating a resonant interference wave and forming a strong energy cluster.
[0149] Reference Figure 6 , Figure 6 This diagram illustrates the time distribution of resonant interference waves from a controllable vibration source provided in an embodiment of the present invention under excitation conditions and different preset scan lengths. Figure 6 As shown, with the increase of scan length, the time to scan to 30Hz gradually increases, and the time for energy clusters to appear on a single shot also increases accordingly. The two are significantly correlated, and the same regularity characteristics as in Table 3 are obtained.
[0150] Reference Figure 7 , Figure 7 This diagram illustrates the energy distribution of a controllable vibration source in the resonant and non-resonant regions under excitation conditions and different preset scan lengths, according to an embodiment of the present invention. Figure 7 As shown, by analyzing the energy distribution of the resonant and non-resonant regions of a controllable source under excitation and different preset scan lengths, it can be determined that the energy of the resonant interference region of the controllable source under excitation is 1-2 times higher than that of the non-resonant region.
[0151] In this embodiment of the invention, raw noise waveform data of a controllable vibration source under at least one mechanical vibration state and raw working waveform data of the controllable vibration source under excitation state and a preset scan length are acquired through a preset detector arrangement. Then, the raw noise waveform data and raw working waveform data are preprocessed to obtain noise waveform data and working waveform data. Finally, based on the noise waveform data, the noise characteristics corresponding to the mechanical vibration state are identified, and based on the working waveform data, the resonant interference wave characteristics of the controllable vibration source under excitation state are identified. This improves the accuracy of mechanical vibration noise identification of the controllable vibration source, achieving the goal of providing a reliable basis for subsequent targeted noise suppression measures. The technical solution provided by this embodiment of the invention can identify mechanical vibration noise of controllable vibration sources in different regions, providing a basis for improving noise suppression in the black triangle region of controllable vibration sources, thereby promoting the application of controllable vibration sources.
