Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of seismic exploration, and in particular, to a method and device, equipment and storage medium for suppressing adjacent shot interference of a vibrator source. Background Art
[0002] In petroleum seismic exploration, the vibrator source excitation technology is an efficient acquisition method in the "two-wide and one-high" exploration. However, due to the influence of the source excitation distance and time, adjacent shot interference single shots will be generated, which will seriously affect the data quality and also interfere with the useful reflected wave information. How to accurately and effectively suppress adjacent shot interference has become a difficult problem in seismic data processing. Whether the adjacent shot interference suppression can be clean without damaging the effective reflected wave is an important goal pursued by seismic data processing engineers.
[0003] The vibrator source excitation technology has the characteristics of "safe and environmentally friendly", and also has the characteristics that parameters such as output power, frequency range, sweep time, and phase can be adjusted according to the specific surface conditions of the work area and the deep seismic geological conditions. Due to the above characteristics, the vibrator source occupies an important position in the field of seismic exploration.
[0004] In conventional vibrator source seismic exploration, adjacent shot interference does not occur. With the development of vibrator source technologies such as the sliding sweep technique and the independent synchronous sweep technique (ISS), ISS is an efficient acquisition technique. This method uses multiple groups of multiple vibrator sources for construction, and each group can be excited as long as it is in place; the receiving instrument uses continuous recording, and the acquisition instrument and the vibrator source operate independently, and the time synchronization between the instrument and the vibrator source is completed through GPS timekeeping. However, the independent synchronous sweep technique will have adjacent shot interference as shown in Figure 1 shown, which affects the quality of the single shot data appearance and is a difficult problem for seismic data processing.

[0050] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are some but not all of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.
[0051] Refer to Figure 2 , embodiments of the present disclosure provide a vibroseis adjacent-shot interference suppression method, and the method includes:
[0052] S1. For each target single-shot record of a specified survey line, obtain the shot point coordinates, maximum offset, recording duration, and acquisition time of the target single-shot record.
[0053] In this embodiment, each target single-shot record of the specified survey line, as well as the shot point coordinates, maximum offset, recording duration, and acquisition time of the target single-shot record, can all be obtained through the vibroseis PSS report. Among them, the consistency when the vibroseis vehicle starts to vibrate is controlled by the start code sent by the encoder to the decoder, and the start is completed through the radios installed on the instrument vehicle and the vibroseis vehicle respectively. After receiving the start code, the decoder starts to control the vibroseis vehicle to vibrate and perform a vibration sweep. During the vibration sweep, the decoder needs to perform a large number of tests and detections, and the results of these tests need to be transmitted to the encoder at the end of the sweep, which is called the PSS report.
[0054] Such as Figure 3As shown in the figure, the PSS report includes information such as line number (LINE), point number (STATION), acquisition time (LOCAL TIME), real north coordinate of the shot point (REAL NORTH), and real east coordinate of the shot point (REAL EAST). Among them, Figure 3 The black box area in it is the time and coordinates.
[0055] S2. Based on the shot point coordinates, maximum offset, recording duration, and acquisition time of the target single-shot record, screen the target adjacent shots that cause interference to this shot.
[0056] S3. Determine the noise suppression area according to the acquisition time difference between this shot and the target adjacent shots and the first arrival wave velocity of the target adjacent shots.
[0057] S4. Use the shot point coordinates of the target adjacent shots to replace the shot point coordinates of this shot, define the relationship between the shot point and the receiving point in the noise suppression area, and suppress the noise suppression area to obtain the denoised area, and generate the denoised target single-shot record.
[0058] Using the shot point coordinates of the target adjacent shots to replace the shot point coordinates of this shot, defining the relationship between the shot point and the receiving point in the noise suppression area is realized through the SPS format file of the target adjacent shots. Among them, the SPS format file includes a shot point data file, a receiving point data file, a relationship data file, and a comment file.
[0059] In this embodiment, in step S2, the screening of the target adjacent shots that cause interference to this shot based on the shot point coordinates, maximum offset, recording duration, and acquisition time of the target single-shot record includes:
[0060] According to the shot point coordinates of the target single-shot record and the shot point coordinates of the known adjacent shots, determine the shot point distance between the known adjacent shots and this shot;
[0061] Take the known adjacent shots with a shot point distance less than the maximum offset from this shot as the candidate adjacent shots;
[0062] According to the acquisition time of the target single-shot record and the acquisition time of each candidate adjacent shot, determine the acquisition time difference between each candidate adjacent shot and this shot;
[0063] Take the candidate adjacent shots with an acquisition time difference greater than 0 and less than the recording duration of the target single-shot record as the target adjacent shots that cause interference to this shot.
[0064] In this embodiment, through the following expression, according to the shot point coordinates of the target single-shot record and the shot point coordinates of the known adjacent shots, determine the shot point distance between the known adjacent shots and this shot:
[0065]
[0066] Wherein, L is the excitation point distance between the known adjacent gun and the present gun, (x0, y0) is the excitation point coordinates of the target single gun record, and (x i , y i ) are the excitation point coordinates of the known adjacent gun.
[0067] In this embodiment, in step S3, determining the noise suppression area according to the acquisition time difference between the present gun and the target adjacent gun and the first arrival wave velocity of the target adjacent gun includes:
[0068] Determining the spatial and temporal positions of the adjacent gun relative to the present gun in the target single gun record according to the difference in the excitation point x coordinates, the excitation point distance, and the acquisition time difference between the target single gun record and the target adjacent gun;
[0069] Based on the first arrival wave velocity of the target adjacent gun and the spatial and temporal positions of the adjacent gun relative to the present gun in the target single gun record, determining the noise suppression area.
[0070] In this embodiment, determining the spatial and temporal positions of the adjacent gun relative to the present gun in the target single gun record according to the difference in the excitation point x coordinates, the excitation point distance, and the acquisition time difference between the target single gun record and the target adjacent gun includes:
[0071] Judging the azimuths of the present gun and the target adjacent gun according to the sign of the difference in the excitation point x coordinates between the target single gun record and the target adjacent gun. If the difference in the excitation point x coordinates between the target single gun record and the target adjacent gun is positive, the target adjacent gun is in the small stake number direction of the present gun; if the difference in the excitation point x coordinates between the target single gun record and the target adjacent gun is negative, the target adjacent gun is in the large stake number direction of the present gun;
[0072] As Figure 4 shown, based on the stake number direction of the target adjacent gun b relative to the present gun a, as well as the excitation point distance L and the acquisition time difference T between the target single gun record and the target adjacent gun, determining the spatial and temporal positions of the adjacent gun relative to the present gun in the target single gun record.
[0073] In this embodiment, determining the noise suppression area based on the first arrival wave velocity of the target adjacent gun and the spatial and temporal positions of the adjacent gun relative to the present gun in the target single gun record includes:
[0074] According to the spatial and temporal positions of the adjacent gun relative to the present gun in the target single gun record, determining the excitation point position of the adjacent gun and the position of the first arrival wave of each trace. Taking the excitation point position of the adjacent gun as the vertex and the position of the first arrival wave of each trace as the side, determining the noise suppression area.
[0075] In this embodiment, suppressing the noise suppression area is achieved by any one of the filtering method, the correlation method, the model method, and the statistical method.
[0076] In this embodiment, in step S4, the generation of the denoised target single-shot record includes:
[0077] Merge the denoised area and the area outside the noise suppression area in the target single-shot record to obtain the denoised target single-shot record.
[0078] In a possible implementation manner, the method further includes:
[0079] Define the relationship between the shot point and the receiving point in the denoised target single-shot record by using the shot point coordinates of this shot.
[0080] See Figures 5 - 9 , the suppression of the noise suppression area to obtain the denoised area and the generation of the denoised target single-shot record include:
[0081] Split the target single-shot record into a noise suppression area m1 and a non-noise suppression area n1, as Figure 5 shown;
[0082] For the split noise suppression area m1 as Figure 6 shown, perform suppression to obtain the denoised area m2, as Figure 7 shown;
[0083] Merge the denoised area m2 and the non-noise suppression area n1 as Figure 8 shown to obtain the denoised target single-shot record, as Figure 9 shown.
[0084] The controllable source adjacent shot interference suppression method of the present disclosure can complete the adjacent shot interference suppression work for each single shot of the entire survey line and is suitable for the suppression of adjacent shot interference of all controllable source high-efficiency acquisition technologies.
