[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] As exploration and development deepen, people have put forward higher requirements for the accuracy of seismic exploration. Seismic exploration not only needs to solve the problems of underground structural imaging and lithology prediction, but also the problem of residual oil distribution. Well seismic exploration technology is an important means to solve the problem of residual oil distribution, and the prediction accuracy of seismic exploration has been improved to 3-5 meters or even 1 meter.

[0028] As surface seismic technology continues to develop, its display methods have become more diverse, including waveform variable area, grayscale, and color displays. While well-drilled seismic data typically borrows these display methods from surface seismic data, well-drilled seismic data, such as VSP (Variable Sweep) data, is a more sophisticated seismic technique with very rich wavefield information. Traditional display methods are no longer intuitive enough, hindering the analysis and understanding of the wavefield in well-drilled seismic data and limiting the effective utilization of the VSP wavefield advantages.

[0029] To address the aforementioned technical problems, the technical concept of this invention is as follows: wavefield separation is performed on well-sourced seismic data rich in wavefield information, and the amplitude ratio between the separated wavefields is calculated. Wavefields within the target value range are assigned color values, that is, the wavefields of interest are marked with colors. This improves the recognizability of well-sourced seismic data and is beneficial for the analysis and understanding of well-sourced seismic data rich in wavefield information.

[0030] Figure 1 This is a flowchart illustrating a method for displaying well-hole seismic data according to an embodiment of the present invention. The executing entity is a well-hole seismic data display device, or an electronic device equipped with a well-hole seismic data display device. For example... Figure 1 As shown, the methods for displaying seismic data from this well include:

[0031] Step S101: Obtain the well seismic data to be displayed and determine the wave field type corresponding to the well seismic data.

[0032] Specifically, the acquired well seismic data to be displayed is not single wavefield data, but rather raw well seismic data with relatively complex wavefields or seismic data before wavefield separation, including but not limited to VSP data, inter-well seismic data, and single-component and multi-component data collected by recording instruments such as geophones and optical fibers.

[0033] Figure 2 This is a schematic diagram of well seismic data to be displayed according to an embodiment of the present invention, wherein the horizontal axis represents the number of traces, with each trace spaced 20m apart, and the vertical axis represents time in milliseconds. Figure 2 It can be seen that the original well-drilled seismic data is quite complex, and using traditional seismic data display methods is not conducive to well-drilled seismic data analysis and wavefield understanding.

[0034] In some embodiments, the wave field type includes at least one of the following: P-wave, S-wave, wellbore wave, and noise wave. Specifically, the well seismic data to be displayed is analyzed to determine the type of well seismic wave field that needs to be displayed in color. The wave field type typically includes up and down P-waves, up and down S-waves or converted waves, and may also be a strong noise wave field such as wellbore wave or fiber optic cable disturbance.

[0035] Step S102: Perform corresponding wavefield separation processing on the well seismic data according to the wavefield type to obtain the separated uplink and downlink wavefields;

[0036] Specifically, the well-ground seismic data is processed by wavefield separation according to the determined wavefield type to obtain wavefield-separated data, including the up-going wavefield and the down-going wavefield. Figure 3a This is a schematic diagram of an upward wave field after wavefield separation, provided in an embodiment of the present invention. Figure 3b This is a schematic diagram of the downlink wavefield after wavefield separation, provided as an embodiment of the present invention.

[0037] In some embodiments, the wavefield separation includes at least one of the following: median filtering, mean filtering, frequency-wavenumber filtering, and singular value decomposition filtering. Specifically, the wavefield separation process includes various methods such as median filtering, mean filtering, frequency-wavenumber filtering, and singular value decomposition filtering. One or more of these methods can be selected, and wavefield separation can be achieved using seismic processing software. For example, median filtering or mean filtering can be performed on P-waves to obtain the corresponding up-going and down-going P-waves, and frequency-wavenumber filtering or singular value decomposition filtering can be performed on noise waves.

[0038] Step S103: Obtain the amplitude ratio of each sampling point of the up-going wave field and the down-going wave field.

[0039] Specifically, the amplitudes of each sampling point of the separated uplink and downlink wave fields are compared to obtain the amplitude ratio (also known as the absolute value ratio) of each sampling point. For example, when one wave field is more than twice as large as the other wave field, it is judged as the dominant wave field, and otherwise it is judged as the equivalent wave field.

[0040] Step S104: Fill the variable area of ​​the waveform with color for the amplitude ratio within the target value range and display it.

[0041] Specifically, the first step is to determine the areas requiring special attention, i.e., the target numerical range, based on the characteristics of the wave field. For the waveform variable area corresponding to the sampling points whose amplitude ratio falls within the target numerical range, color filling is applied. For the waveform corresponding to the sampling points whose amplitude ratio falls outside the target numerical range, no processing is performed, and the previous black filling is still used.

[0042] The method for displaying well-ground seismic data provided in this embodiment of the invention involves acquiring the well-ground seismic data to be displayed and determining the wavefield type corresponding to the well-ground seismic data; performing corresponding wavefield separation processing on the well-ground seismic data according to the wavefield type to obtain the separated up-going wavefield and down-going wavefield; obtaining the amplitude ratio of each sampling point of the up-going wavefield and down-going wavefield; color-filling the waveform variable area regions whose amplitude ratios are within the target value range, and then displaying them. In other words, this embodiment of the invention performs wavefield separation on well-ground seismic data rich in wavefield information, calculates the amplitude ratio between the separated wavefields, and assigns color values ​​to wavefields within the target value range, thereby improving the recognizability of well-ground seismic data and facilitating the analysis and wavefield understanding of well-ground seismic data rich in wavefield information.

[0043] Based on the above embodiments, Figure 4 A flowchart illustrating another method for displaying well seismic data provided in an embodiment of the present invention is shown below. Figure 4 As shown, the methods for displaying seismic data from this well include:

[0044] Step S401: Obtain the well seismic data to be displayed and determine the wave field type corresponding to the well seismic data.

[0045] Step S402: Perform corresponding wavefield separation processing on the well seismic data according to the wavefield type to obtain the separated uplink and downlink wavefields.

[0046] Step S403: Determine multiple numerical ranges, and determine at least one of the multiple numerical ranges as the corresponding target numerical range.

[0047] Step S404: Obtain the amplitude ratio of each sampling point of the up-going wave field and the down-going wave field, and determine that the amplitude ratio of each sampling point falls within one of the multiple numerical ranges.

[0048] Step S405: Fill the waveform variable area regions with corresponding colors for amplitude ratios within different target value ranges, and then display them.

[0049] The implementation methods of steps S401 and S402 in the embodiments of the present invention are similar to those of steps S101 and S102 in the above embodiments, and will not be described again here.

[0050] The difference from the above embodiments is that, in order to further improve the intuitive understanding of the rich wave field in the well, in this embodiment, multiple numerical ranges are determined, and at least one of the multiple numerical ranges is determined as the corresponding target numerical range; the amplitude ratio of each sampling point of the up-going wave field and the down-going wave field is obtained, and the amplitude ratio of each sampling point is determined to be in one of the multiple numerical ranges; the waveform variable area regions with amplitude ratios in different target numerical ranges are filled with corresponding colors and displayed.

[0051] Specifically, the wave field can be divided into multiple non-overlapping numerical ranges based on its characteristics, such as the first numerical range, the second numerical range, the third numerical range, and the fourth numerical range. It can also be determined which numerical range the amplitude ratio of each sampling point of the separated uplink and downlink wave fields falls within. At least one of the multiple numerical ranges can be identified as the target numerical range. For example, if the first, second, and third numerical ranges are identified as the three target numerical ranges to be of interest, then different colors can be used to fill the waveform variable area regions that fall within the first and second numerical ranges. Figure 5 This is a schematic diagram of well-filled seismic data after color filling, provided as an embodiment of the present invention. Figure 5 As shown, the waveform area within the first numerical range can be filled with red, the waveform area within the second numerical range can be filled with blue, and the waveform area within the third numerical range can be filled with purple, etc.

[0052] In some embodiments, the plurality of numerical ranges include a first numerical range, a second numerical range, and a third numerical range; wherein the first numerical range is greater than a first preset threshold, the second numerical range is less than or equal to the first preset threshold and greater than or equal to a second preset threshold, and the third numerical range is less than the second preset threshold.

[0053] Specifically, the first and second preset thresholds can be set according to the characteristics of the wave field. Generally, the first preset threshold is greater than the second preset threshold, and the first and second preset thresholds are reciprocals of each other. For example, if the first preset threshold is 2 and the second preset threshold is 0.5, the three numerical ranges are (∞, 2), [2, 0.5], and (0.5, 0). The absolute values ​​of each sample point in the separated uplink and downlink wave fields are compared to obtain the absolute value ratio, and the absolute value ratio is divided into three ranges: (∞, 2), [2, 0.5], and (0.5, 0). [2, 0.5] can be selected as the target numerical range, and the area corresponding to [2, 0.5] is filled with red, while other areas remain filled with black.

[0054] In some embodiments, if the amplitude ratio of the corresponding sampling points of the uplink wave field and the downlink wave field is within a first numerical range, the uplink wave field is determined to be the dominant wave field; if the amplitude ratio of the corresponding sampling points of the uplink wave field and the downlink wave field is within a second numerical range, the uplink wave field and the downlink wave field are determined to be comparable wave fields; if the amplitude ratio of the corresponding sampling points of the uplink wave field and the downlink wave field is within a third numerical range, the downlink wave field is determined to be the dominant wave field. For example, at a certain sampling point, if the up-wave field is more than twice the size of the down-wave field, that is, the ratio of the absolute values ​​of the up-wave field and the down-wave field is in (∞, 2), then the up-wave field is determined to be the dominant wave field; if the absolute values ​​of the up-wave field and the down-wave field are similar, that is, the ratio of the absolute values ​​of the up-wave field and the down-wave field is in [2, 0.5], then the up-wave field and the down-wave field are determined to be comparable wave fields; if the down-wave field is more than twice the size of the up-wave field, that is, the ratio of the absolute values ​​of the up-wave field and the down-wave field is in (0.5, 0), then the down-wave field is determined to be the dominant wave field.

[0055] The method for displaying well-ground seismic data provided in this embodiment of the invention determines multiple numerical ranges and identifies at least one of these ranges as a corresponding target numerical range; obtains the amplitude ratio of each sampling point in the up-row and down-row wavefields and determines that the amplitude ratio of each sampling point falls within one of the multiple numerical ranges; fills the waveform variable area regions with corresponding colors for amplitude ratios falling within different target numerical ranges and displays them; that is, this embodiment of the invention uses different colors to fill different wavefields of interest, further improving the recognizability of well-ground seismic wavefields and facilitating the analysis and understanding of well-ground seismic data rich in wavefield information.
