After each vibration of the controllable seismic source is finished, the seismic source box body can calculate a ground force signal according to the mass of the seismic source heavy hammer, the acceleration of the heavy hammer, the mass of the flat plate and the acceleration of the flat plate, and the ground force signal can form force signal data with data such as seismic source reference signals, the acceleration of the heavy hammer, the acceleration of the flat plate, partial expansion QC information and the like. The force signal data may be stored in the form of a file, which is commonly referred to as a vibroseis force signal file. And storing a force signal file corresponding to each vibration in a box body of the vibroseis. However, in actual operation, when the vibroseis box records the force signal file, there are situations that part of the force signal file is not recorded, the recorded information is wrong, or the recorded force signal data is abnormal, and the accuracy of subsequent seismic data processing is affected.

In view of the above technical problems, the present application provides a method for quality control of vibroseis force signal data, which may first obtain force signal data after vibroseis vibration, for example, obtain force signal data by obtaining a force signal file stored in a vibroseis box. And then, judging whether the force signal data meet a preset requirement or not to obtain a judgment result, wherein the preset requirement can be preset according to actual requirements. And when the force signal data do not meet the preset requirement, feeding back the judgment result to the controllable seismic source so that the controllable seismic source performs re-vibration based on the judgment result to obtain the force signal data meeting the preset requirement. Therefore, the accuracy of the force signal data for subsequent data processing is effectively ensured.

Fig. 1 is a schematic flow chart of an embodiment of a method for controlling the quality of vibroseis force signal data provided in this specification. Although the present specification provides the method steps or apparatus structures as shown in the following examples or figures, more or less steps or modules may be included in the method or apparatus structures based on conventional or non-inventive efforts. In the case of steps or structures which do not logically have the necessary cause and effect relationship, the execution order of the steps or the block structure of the apparatus is not limited to the execution order or the block structure shown in the embodiments or the drawings of the present specification. When the described method or module structure is applied to a device, a server or an end product in practice, the method or module structure according to the embodiment or the figures may be executed sequentially or in parallel (for example, in a parallel processor or multi-thread processing environment, or even in an implementation environment including distributed processing and server clustering).

In a specific embodiment, as shown in fig. 1, in an embodiment of a method for controlling vibroseis force signal data, the method may include:

and S102, acquiring force signal data of the vibroseis.

In this embodiment, the force signal data of the vibroseis may include force signal data stored in a box of the vibroseis after each vibration of the vibroseis is finished. For example, data may include ground force signals, seismic source reference signals, weight acceleration, slab acceleration, and partially extended QC information.

In one embodiment of the present description, the force signal data may be obtained based on the type of tank. The type of the box may include a type of the box corresponding to the vibroseis, force signal data may be different for different box types, and the force signal data corresponding to each box is determined according to actual conditions, and is not limited herein. Typically, the force signal data may be stored in a file on the source casing, referred to as a force signal file. In an embodiment of the present specification, the vibroseis force signal data stored in the seismic source box may be retrieved according to the scanning index, for example, a force signal file may be retrieved through a force signal data storage directory or an extended QC directory, etc., based on the scanning index information of the vibroseis, so as to obtain the force signal data. In another embodiment of the present specification, a file query time interval may also be preset, and the force signal file is adjusted according to the time interval to obtain the force signal data.

In an embodiment of the present specification, in the vibroseis force signal data stored in the seismic source box according to the scan index, when the force signal data cannot be retrieved or the retrieved force signal data is incomplete, a re-oscillation request may be issued to the vibroseis, and force signal data after the vibroseis re-oscillation may be obtained. If the force signal data cannot be recalled normally, the force signal data file may not be saved. In an embodiment of the present specification, after obtaining the force signal file of the vibroseis, it may be determined whether the force signal file can be normally analyzed, and if the force signal file cannot be normally analyzed, the corresponding force signal data is incomplete. Of course, it is also possible to predetermine the type of parameter that the force signal data should include, and then compare the acquired force signal data with the predetermined type of parameter that the force signal data should include one by one, and if some or all of the data is found to be missing, the force signal data is not complete.

For example, for the recorded force signal data of the Vibpro box, it can be judged whether the force signal file can be normally analyzed, and if the force signal file cannot be normally analyzed, the force signal file is incomplete. For a force signal file recorded by the VE464 box, it can be checked whether the force signal file exists or not according to the vibration frequency information in the extended QC.

Of course, in an embodiment of the present specification, a determination result that the force signal data cannot be retrieved or the retrieved force signal data is incomplete may also be fed back to the vibroseis, for example, the force signal is not present or the force signal is incomplete; and force signal data of incomplete reasons or specific missing force signal data can be fed back to the controllable seismic source at the same time. The controlled vibration source is properly adjusted and then re-vibrated so as to reduce the error rate.

And S104, judging whether the force signal data meet preset requirements or not, and obtaining a judgment result.

In this embodiment, the quality control parameter types of the force signal data to be quality-controlled and the quality control parameter conditions that each quality control parameter needs to satisfy may be preset and stored. And then, judging whether the quality control parameters meet corresponding quality control parameter conditions or not, and obtaining a judgment result.

In an embodiment of the present specification, the determination result may include that the force signal meets or does not meet a preset requirement. In another embodiment of the present specification, the determination result may further include a type of the quality control parameter that is not specifically compliant with the condition of the quality control parameter. In other embodiments of the present specification, the determination result may further include a quality control parameter type that does not meet the quality control parameter condition and a corresponding non-meeting reason description.

For example, when the force signal data meets the preset requirement, the judgment result is that the force signal is normal; and when the force signal data does not meet the preset requirement, judging that the force signal is abnormal. If the seismic source output value does not accord with the corresponding seismic source output condition, the judgment result can also comprise abnormal seismic source output or overproof seismic source output, and meanwhile, the judgment result can also comprise the practical seismic source output value data, the preset seismic source output data in the output signal data, the non-conformity reason description of the practical seismic source output value lower than the preset seismic source output value and the like. Therefore, the controllable seismic source can adjust the excitation parameters in a targeted manner according to the judgment result, and the efficiency of obtaining the force signal data meeting the preset requirement is improved.

In an embodiment of the present disclosure, the quality control parameter may be a preset force signal data parameter to be monitored. For example, the quality control parameters may include parameters of seismic source properties such as average phase, peak phase, average distortion, peak distortion, and the like, and may also include parameters such as energy ratio of force signal to reference signal, seismic source output, and the like. The quality control parameters may include some or all of the parameter types in the force signal data.

In one embodiment of the present description, a seismic source attribute specified in force signal data may be obtained, and it may be determined whether the specified seismic source attribute meets a specified seismic source attribute threshold condition, and if not, the force signal data does not meet a preset requirement. In one embodiment of the present description, the source attributes may include some key indicators of source performance, for example, average phase, peak phase, average distortion, peak distortion, and the like. In specific implementation, the seismic source attributes required to be controlled by the seismic source can be pre-specified according to actual needs, and the specified seismic source attributes and corresponding seismic source attribute requirements are stored. For example, it may be determined whether the average phase exceeds a preset phase threshold, and if so, the force signal data is not normal. Accordingly, the determination result may include that the average phase exceeds the standard.

S1041, judging whether the energy of the force signal data is normal.

In one embodiment of the present description, the ground force signal of the vibroseis can be calculated according to the weight acceleration, the weight mass, the plate acceleration and the plate mass. For example, the ground force signal may be calculated according to the following formula:

In specific implementation, the amplitude value of each sampling point of the reference signal can be divided by the maximum amplitude value in the reference signal, and the amplitude data of the reference signal is normalized; similarly, the amplitude data of the ground force signal may be normalized by dividing the amplitude value of each sample of the ground force signal by the maximum amplitude value in the ground force signal. The normalization process can be performed with reference to the following formula:

r_i＝r_i/r_max

f_i＝f_i/f_max

(3) Respectively calculating the root-mean-square energy of the reference signal and the ground force signal in each time window, wherein the calculation formula can be as follows:

wherein E is_rRepresenting the root mean square energy, r, of the reference signal in a time window_iRepresenting the amplitude value of a sample of the reference signal in a time window, E_fRepresenting the root mean square energy, f, of the ground force signal within a time window_iThe amplitude value of the sampling points of the ground force signal in the time window is shown, and n represents the number of the sampling points in a single time window.

(4) The ratio p of the rms energy of the surface force signal to the rms energy of the reference signal in each time window can be calculated as follows:

p＝E_f/E_r*100

(5) an energy threshold value can be preset, then, from the zero moment, whether the p value of each time window is smaller than the preset energy threshold value is sequentially judged, if the p is smaller than the preset energy threshold value, the force signal energy is abnormal, and the force signal data can be determined not to meet the preset requirement. Accordingly, the determination may include a source energy anomaly. Otherwise, carrying out energy check of the next time window, and repeating the steps (2) to (5) until the end of the ground force signal. And if the energy corresponding to all time windows of the ground force signal is normal, indicating that the energy of the force signal is normal.

Accordingly, the determination may include a source force anomaly.

In another embodiment of the present specification, status code data in the force signal data may be acquired, and it is determined whether the status code data belongs to preset status code data, and if not, the force signal data does not satisfy a preset requirement. In specific implementation, it may be determined whether the status code acquired in the force signal data is in the normal status code list, and if not, the status code data is incorrect, and the force signal data does not meet the preset requirement. Accordingly, the determination result may include a status code data error.

And S1045, judging whether the number of the suppression time windows in the force signal data is normal.

Accordingly, the determination result may include suppressing the time window number error.

It should be noted that the above types of quality control parameters are merely examples in this specification, and in particular, the types of quality control parameters may include one or more of the above types of parameters, and may also include other types of parameters. The setting can be carried out by itself according to actual operation, and is not limited here.

And S106, if the force signal data do not meet the preset requirement, feeding back the judgment result to the controllable seismic source so that the controllable seismic source performs re-vibration based on the judgment result to obtain the force signal data meeting the preset requirement.

In this embodiment, when it is determined that the force signal data does not satisfy the preset requirement, the determination result may be fed back to the vibroseis, and meanwhile, a warning message or a re-oscillation requirement may be sent to the vibroseis. And the controllable seismic source performs repeated vibration according to the judgment result to obtain force signal data meeting the preset requirement. In the specific implementation, the judgment result can be fed back to the vibroseis in the form of characters, graphs, sounds and the like, and a warning or a re-vibration request can be sent out.

In an embodiment of the present specification, the vibroseis makes an appropriate determination according to the feedback determination result, and when the excitation parameter needs to be adjusted, the vibroseis may adjust the excitation parameter and then vibrate again to obtain the force signal data meeting the preset requirement.

And the controllable seismic source performs the repeated vibration according to the received repeated vibration requirement or the repeated vibration and parameter adjustment requirement so as to obtain force signal data meeting the preset requirement.

In the solutions provided in one or more embodiments of the present description, the eligibility of the force signal data of the controllable seismic source may be monitored, and if the force signal data of the controllable seismic source does not meet the preset requirement, the corresponding determination result may be fed back to the corresponding controllable seismic source. The controllable seismic source automatically judges whether the re-vibration is needed according to the corresponding judgment result, and if the re-vibration is needed, the re-vibration is executed after the parameter data needing to be adjusted are adjusted; and the re-vibration can be carried out according to the re-vibration requirement or the re-vibration addition parameter adjustment requirement so as to obtain force signal data meeting the preset requirement. Therefore, the qualification of the acquired force signal data can be further ensured by utilizing the scheme.

In another embodiment of the present disclosure, a force signal quality control type may be preset and stored, wherein the quality control type may include real-time quality control or non-real-time quality control.

For non-real-time quality control, in one embodiment of the present description, the stored force signal data and corresponding determination results may be statistically analyzed. And then, screening out force signal data meeting the preset requirement according to a judgment result corresponding to the force signal data for subsequent data processing. Of course, the unsatisfactory force signal data can be counted, the unsatisfactory force signal data is properly corrected according to the corresponding judgment result, and then the corrected force signal data is used for subsequent data processing so as to improve the accuracy of the subsequent data processing.
