[0066] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0067] The inventors found that due to the differences between different detectors of the same type and the slight differences in the burial conditions, the seismic data received during construction were different. Figure 1As shown in the figure, when using different seismic instruments to receive seismic data at the same location, the amplitude of the waveform is obviously different. This leads to the lack of scientificity and accuracy when using different seismic instruments to collect data together. Therefore, a scientific and accurate device for converting the numerical conversion coefficients of data collected by different seismic instruments is needed to lay the foundation for subsequent high-precision data processing and interpretation.

[0068] In order to solve the above technical problems, a method for determining numerical conversion coefficients for data acquisition of different seismic instruments is provided in an embodiment of the present invention. The method can be applied to land two-dimensional and three-dimensional seismic exploration. When different seismic instruments are used for data acquisition, the data collected by each seismic instrument can be accurately converted into the same type of data. Figure 2 As shown, the method may include the following steps:

[0069] Step S21: Use the detector homologous output device to connect with at least two different types of seismic instruments and the same detector respectively, so as to use the at least two different types of seismic instruments to collect seismic data received by the same detector.

[0070] Step S22: Based on the seismic data collected by the at least two different types of seismic instruments and received by the same detector, a consistency test is performed on the at least two different types of seismic instruments. If the preset consistency requirements are met, step S23 is executed.

[0071] Step S23, based on the seismic data collected by the same detector and collected by at least two different types of seismic instruments, determine the numerical conversion coefficients used for data collection by different seismic instruments by using the root mean square ratio method.

[0072] The method for determining the numerical conversion coefficients for data acquisition of different seismic instruments provided in the embodiment of the present invention is to simultaneously transmit the signal generated by the same detector to two different types of seismic instruments, and analyze the seismic data by the root mean square ratio method to determine the numerical conversion coefficients for data acquisition of different types of seismic instruments. The method performs consistency verification on seismic instruments at different nodes, and by clarifying the amplitude conversion relationship of seismic data collected by different seismic instruments, it not only solves the problem of insufficient number of seismic instruments of a single type, but also further improves the construction efficiency and seismic data acquisition accuracy, and provides a high-precision, scientific and reasonable basis for the joint construction of multiple seismic instruments.

[0073] In a detailed embodiment, the method for determining the numerical conversion coefficients for data acquisition of the above-mentioned different seismic instruments can refer to Figure 3 As shown, the specific steps include:

[0074] Step S31, based on the parallel circuit principle, reorganize the detector output port to make a detector homologous output device.

[0075] The inventor of this step is based on the fact that the existing detector strings generally have two ports with different interface modes, one port is used to connect the detector strings, and the other port is used to connect the seismic instrument. The inventor improves the current output port based on the following Figure 4 The working principle of the detector homologous output parallel circuit shown in the figure is to connect at least one output port connected to a seismic instrument in parallel, and transmit the seismic signal received by the same detector to at least two instruments at the same time. Figure 5 As shown, the embodiment of the present invention is described by taking one output port connected in parallel as an example. Figure 5 This is the physical schematic diagram of the modified detector string.

[0076] Step S32: Use the detector homologous output device to respectively connect at least two seismic instruments of the same type and the same detector, so as to use the seismic instruments of the same type to respectively collect seismic data received by the same detector.

[0077] Step S33, perform waveform data analysis on seismic data received by the same detector respectively collected by at least two seismic instruments of the same type, so as to verify the feasibility of the detector homologous output device based on the degree of waveform matching; if the detector homologous output device meets the feasibility requirements, execute step S34; otherwise, end.

[0078] Step S32 and step S33 in the embodiment of the present invention verify the feasibility of the above-mentioned detector homologous output device. In the specific implementation, a number of detector homologous output devices are randomly selected, and the two output ports are connected to the same type of seismic instruments. The degree of consistency of the signals of the two output ports is compared based on waveform data analysis. The two have a very high degree of consistency, the waveforms basically overlap, the numerical errors of different sampling points are all within 1%, and the consistency is greater than 99%. Only detector homologous output devices that meet such requirements can be used.

[0079] Reference Figure 6 and Figure 7 As shown, the test experiment in the embodiment of the present invention compares the degree of coincidence of the signals of the same source output ports of 5 detectors, among which Figure 6 1-5 is the output data curve of port 1 of the same source output device 1-5, and 11-55 is the output data curve of port 2. Figure 6 The signal waveforms output from different ports are basically the same. Figure 7 As shown in the figure, the numerical error statistics of different sampling points of output signals from different ports show that the numerical errors of different sampling points are all within 1%, which meets the design requirements.

[0080] Step S34: Use the detector homologous output device to connect with at least two different types of seismic instruments and the same detector respectively, so as to use the at least two different types of seismic instruments to collect seismic data received by the same detector.

[0081] This step is consistent with step S21 in the above embodiment. Figure 8 As shown, it is a physical schematic diagram of using the detector homologous output device to connect with the detector and different types of seismic instruments respectively. After the connection, it is necessary to perform consistency test on the seismic instrument, that is, execute the following step S35. In a seismic acquisition project, multiple seismic instruments are jointly constructed, and the consistency of various instruments should be tested. Only when the consistency between seismic instruments is high can the requirements of joint construction be met, and the conversion coefficients between different instruments are meaningful. In this embodiment, the two output ports of the detector homologous output device are used to connect two different types of seismic instruments.

[0082] Step S35: Based on the seismic data collected by the same detector of at least two different types of seismic instruments, a consistency test is performed on the at least two different types of seismic instruments. If the preset consistency requirement is met, step S36 is executed; otherwise, the process ends.

[0083] The specific steps of performing consistency testing in the embodiment of the present invention are as follows:

[0084] Normalize the seismic data received by the same detector collected by at least two different types of seismic instruments. Normalization is to divide each sample point of the seismic data collected by the seismic instrument by the maximum value in the data. After normalization, the data is more intuitive.

[0085] The waveform comparison method and / or the single-channel phase comparison method are used to perform error degree analysis on the seismic data after normalization processing, so as to perform consistency test on at least two different types of seismic instruments based on the error degree analysis results.

[0086] In this step, the difference between the two seismic instruments is qualitatively and quantitatively analyzed. By comparing and analyzing the error degree of the two output port data of the same homologous output device, the consistency of the two seismic instruments is determined. The consistency degree is presented in percentage, and the threshold value is determined according to the consistency requirements of the implementation unit for different instruments. The instrument consistency comparison can be carried out by waveform comparison method and single-channel phase comparison method. Fig. 9 and Fig.10 The consistency comparison analysis diagram of the wired seismometer G3I and the wireless seismometer eSeis is shown, from which the threshold value can be set to determine whether it meets the consistency test standard.

[0087] In an embodiment of the present invention, a waveform comparison method and / or a single-channel phase comparison method are used to perform an error degree analysis on the seismic data after normalization processing, which may specifically include: first, laying out a two-dimensional survey line based on multiple groups of detector homologous output devices to respectively connect with at least two different types of seismic instruments and multiple detectors; then, obtaining single-shot seismic data and / or profile seismic data based on at least two different types of seismic instruments; finally, using the waveform comparison method and / or the single-channel phase comparison method, performing an error degree analysis on the single-shot seismic data and / or profile seismic data after normalization processing.

[0088] Reference Fig.11 and Fig.12 As shown in the figure, in the specific implementation, a two-dimensional line test method is adopted, and a two-dimensional survey line is laid out using 600 detector homologous output devices to obtain single shot and profile data. Through qualitative and quantitative analysis of single shot profile and profile data, the data has high consistency and high spectrum consistency. Fig.11 The left side shows a single shot comparison chart, and the right side shows an energy and spectrum analysis chart; Fig.12 The left side is a cross-section comparison diagram, and the right side is a spectrum analysis diagram.

[0089] Step S36, based on the seismic data collected by the same detector using at least two different types of seismic instruments, determine the numerical conversion coefficients used for data collection by different seismic instruments using the root mean square ratio method.

[0090] This step is to calculate the numerical conversion coefficient using the seismic data collected by each seismic instrument after it is determined in the above step S35 that each seismic instrument meets the consistency requirement. Specifically, it includes the following steps:

[0091] First, normalize the seismic data received by the same detector collected by at least two different types of seismic instruments; then, determine the root mean square value of each seismic record obtained by different seismic instruments based on the normalized seismic data; third, determine the root mean square ratio used for data collection by different seismic instruments based on the root mean square values ​​determined by different seismic instruments; fourth, determine the simplest integer ratio based on the root mean square ratio, and determine the numerical conversion coefficient used for data collection by different seismic instruments with the simplest integer ratio. Fig.13 As shown, the single shot record comparison before and after using the numerical conversion coefficient, Fig.13 The left side is the single shot record before numerical conversion, and the right side is the single shot record after numerical conversion. The latter seismic record is more reasonable and accurate.

[0092] In a specific example, we take the 3D seismic exploration of a certain area as an example. The surface conditions in this area are complex. There is a county town in the south, farmland and Gobi in the middle, and tall mountains in the north. In order to adapt to the complex surface conditions and environmental noise control in the work area, we refer to Fig.14As shown, four types of seismic instruments were used for joint construction (wired seismometer G3i, wireless seismometer Hardvox, eSeis, smartsolo). Through the above method, the numerical conversion coefficients for data acquisition of different seismic instruments were calculated and determined as shown in Table 1 below:

[0094] Serial number Types of seismic instruments Numeric conversion factor 1 eSeis 4000 2 Hardvox 4000 3 G3i 4000 4 SmartSolo 1

[0095] Through the above method, the consistency of data from different node instruments is compared, which helps Kuche 3D adopt multiple node instruments for construction, solves the problem of insufficient number of single type of node instruments, and clarifies the amplitude conversion relationship between different instruments, improving construction efficiency and data collection accuracy.

[0098] Step S152: if the preset consistency requirement is met, the seismic data received by the same detector based on at least two different types of seismic instruments are used to determine the numerical conversion coefficient for data acquisition by different seismic instruments by using the root mean square ratio method.
