Description

Technical Field

[0001] The present invention relates to the field of three-dimensional seismic exploration acquisition, and more specifically, to a method, device, electronic device, and medium for determining shot point spacing and geophone point spacing. Background Art

[0002] During onshore three-dimensional seismic acquisition, removing the interference waves generated by complex surface is an important link to improve the quality of seismic data. Effective removal of interference waves requires the three-dimensional seismic acquisition observation system to completely sample the interference waves.

[0003] In the design of shot point spacing and geophone point spacing of traditional three-dimensional observation systems, generally, anti-aliasing sampling of reflected waves is considered. However, due to the long wave field of reflected waves, the requirements for geophone point spacing and shot point spacing are relatively low, so generally, the designed geophone point spacing and shot point spacing are relatively large. However, since the wave field of near-surface interference is generally relatively small, the relatively large geophone point spacing and shot point spacing cannot completely sample the near-surface interference waves and cannot remove aliasing, seriously affecting the subsequent three-dimensional cone denoising effect.

[0004] Theoretically, the smaller the point spacing of geophones and shot points, the more complete the sampling of the surface wave field. However, the smaller the geophone point spacing and shot point spacing, the greater the exploration investment. Without the support of actual data, the designed geophone point spacing and shot point spacing may be too small, resulting in poor economy of three-dimensional acquisition. Seismic acquisition usually needs to balance between technical effects and economy.

[0005] Therefore, it is necessary to develop a method, device, electronic device, and medium for determining shot point spacing and geophone point spacing of an onshore three-dimensional seismic acquisition observation system.

[0006] The information disclosed in the background art section of the present invention is only intended to deepen the understanding of the general background art of the present invention, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art known to those skilled in the art.

[0044] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein.

[0045] The present invention provides a method for determining shot point spacing and geophone point spacing, including:

[0046] Determine the geophone row / column and shot point row / column; in one example, the geophone row / column and the shot point row / column are arranged in a cross pattern.

[0047] Specifically, determine the geophone row / column and the shot point row / column, and arrange them in a cross pattern for the purpose of static correction work in field data survey. The spacing between geophones is equal, and the spacing between shot points is equal. Different geophone point spacings and shot point spacings can be set according to the characteristics of interference waves in different regions for investigation, and the principle is to be as small as possible less than half of the minimum apparent wavelength of interference waves for subsequent analysis and comparison of different point spacings.

[0048] Extract data from the geophone row / column and the shot point row / column respectively, and establish multiple groups of geophone data volumes and shot point data volumes according to different shot point spacings and geophone point spacings; in one example, it further includes: performing static correction on all the acquisition data of the geophone row / column and the shot point row / column, and then establishing the geophone data volume and the shot point data volume.

[0049] Specifically, perform static correction on all the acquisition data of the geophone row / column and the shot point row / column. After the static correction is completed, extract data from the geophone row / column and the shot point row / column respectively, and establish multiple groups of geophone data volumes and shot point data volumes according to different shot point spacings and geophone point spacings.

[0050] Calculate the signal-to-noise ratio of each group of geophone data volumes and shot point data volumes; in one example, it further includes: denoising the geophone data volume and the shot point data volume, and then calculating the signal-to-noise ratio of each group of geophone data volumes and shot point data volumes.

[0051] In one example, the denoising method is three-dimensional cone denoising.

[0052] Specifically, use the three-dimensional cone denoising technology to denoise the geophone data volume and the shot point data volume, and then calculate the signal-to-noise ratio of each group of geophone data volumes and shot point data volumes.

[0053] Compare and determine the optimal shot point spacing and geophone point spacing. In one example, compare and determine the optimal shot point spacing and geophone point spacing according to economy and signal-to-noise ratio.

[0054] Specifically, quantitatively analyze the signal-to-noise ratio of the denoised data at different shot point intervals and sort them. Considering the technical effect and economy comprehensively, select the combination of the optimal shot point interval and receiver point interval as the shot point interval and receiver point interval of the 3D seismic observation system. In theory, the smaller the shot point interval and receiver point interval, the better the denoising effect, but the worse the economy. Usually, a compromise point interval needs to be selected to achieve a perfect combination of economy and denoising effect.

[0055] The present invention also provides a device for determining the shot point interval and receiver point interval, including:

[0056] A row and column establishment module, which determines the receiver point rows and columns and the shot point rows and columns; in one example, the receiver point rows and columns and the shot point rows and columns are arranged in a cross shape.

[0057] Specifically, determining the receiver point rows and columns and the shot point rows and columns, and arranging the receiver point rows and columns and the shot point rows and columns in a cross shape is for the static correction work of field data survey. The distance between adjacent receiver points is equal, and the distance between adjacent shot points is equal. Different receiver point intervals and shot point intervals can be set according to the characteristics of interference waves in different regions for investigation. The principle is to be as small as possible less than half of the minimum apparent wavelength of the interference waves, so as to conduct analysis and comparison of different point intervals subsequently.

[0058] An extraction module, which extracts data from the receiver point rows and columns and the shot point rows and columns respectively, and establishes multiple groups of receiver point data volumes and shot point data volumes according to different shot point intervals and receiver point intervals; in one example, it further includes: performing static correction on all the acquisition data of the receiver point rows and columns and the shot point rows and columns, and then establishing the receiver point data volume and the shot point data volume.

[0059] Specifically, perform static correction on all the acquisition data of the receiver point rows and columns and the shot point rows and columns. After the static correction is completed, extract data from the receiver point rows and columns and the shot point rows and columns respectively, and establish multiple groups of receiver point data volumes and shot point data volumes according to different shot point intervals and receiver point intervals.

[0060] A calculation module, which calculates the signal-to-noise ratio of each group of receiver point data volumes and shot point data volumes; in one example, it further includes: performing denoising on the receiver point data volume and the shot point data volume, and then calculating the signal-to-noise ratio of each group of receiver point data volumes and shot point data volumes.

[0061] In one example, the denoising method is 3D cone denoising.

[0062] Specifically, use the 3D cone denoising technology to perform denoising on the receiver point data volume and the shot point data volume, and then calculate the signal-to-noise ratio of each group of receiver point data volumes and shot point data volumes.

[0063] A comparison module, which compares and determines the optimal shot point interval and receiver point interval. In one example, according to the economy and signal-to-noise ratio, compare and determine the optimal shot point interval and receiver point interval.

[0064] Specifically, the signal-to-noise ratios of the data after denoising at different shot point intervals are quantitatively analyzed and sorted. Considering the technical effects and economy comprehensively, the optimal combination of the shot point interval and the geophone point interval is selected as the shot point interval and the geophone point interval of the three-dimensional seismic observation system. In theory, the smaller the shot point interval and the geophone point interval, the better the denoising effect, but the worse the economy. Usually, a compromise point interval needs to be selected to achieve a perfect combination of economy and denoising effect.

[0065] The present invention also provides an electronic device, which includes: a memory storing executable instructions; and a processor that runs the executable instructions in the memory to implement the above method for determining the shot point interval and the geophone point interval.

[0066] The present invention also provides a computer-readable storage medium storing a computer program, which when executed by a processor implements the above method for determining the shot point interval and the geophone point interval.
