Background

In the working fields of seismic exploration acquisition, geological survey and the like, along with higher and higher requirements on exploration precision, the surface conditions of a work area are more and more complex, great challenges and difficulties are brought to the design of an observation system of a barrier area and the construction of shot-geophone points, namely, the shot-geophone points cannot be arranged in a part of the area of the exploration work area due to barriers, so that data are lost during seismic acquisition, and particularly, the middle-shallow layer is more prominent. The data missing of the obstacle area greatly affects the inversion accuracy of the near-surface first-arrival wave velocity, and the velocity of a target layer is deviated due to the accumulation effect, so that the imaging quality is affected.

According to the technical scheme, after the data subset is divided in the later-stage seismic data processing according to the Offset Vector tiles (OVT, Offset Vector Tile), the uniformity of the covering times is poor, and further the subsequent interpolation processing effect is poor, so that the requirements of improving the Offset imaging quality and pre-stack inversion cannot be met.

Hereinafter, techniques according to embodiments of the present application will be described.

Near-surface velocity modeling is an important link for processing land seismic data. The precision and resolution of the near-surface velocity model directly influence the precision and effect of subsequent static correction, velocity analysis and offset imaging. The seismic first-motion wave information can reflect the shallow velocity structure within 500 meters of the near-surface, and the current common means for carrying out near-surface modeling by utilizing body waves comprises two major types of travel time tomography and waveform inversion.

Forward modeling (forward modeling): in geophysical exploration research, a theoretical value (mathematical simulation) is calculated by constructing a mathematical model according to shape, attitude and physical property data of a geologic body, or a numerical value (physical simulation) of a geophysical effect generated by constructing a solid model to observe the model is called forward simulation. In the process of explaining the geophysical data, the forward modeling result is often compared with the actual geophysical exploration data, and the model is continuously corrected, so that the modeling result is as close as possible to the actual data, and the explaining result is closer to the objective reality. The process of such comparison is also called selection.

The SEGY is that seismic data is generally organized in units of seismic traces and stored in an SEG-Y file format. The SEG-Y format is one of the standard tape data formats proposed by SEG (society of Exploration geography), which is one of the most common formats of seismic data in the oil Exploration industry.

Fig. 1 is a flowchart of a seismic data acquisition method according to an embodiment of the present application, and as shown in fig. 1, the method is described in the embodiment of the present application by taking a computer device as an example. The seismic data acquisition method comprises the following steps:

101. the computer equipment determines theoretical observation information according to work area information, wherein the work area information is used for indicating a non-obstacle area and an obstacle area, and the theoretical observation information is used for indicating a shot point position, a receiving point position, a line number, a track number, a shot point number, a track distance, a receiving line distance, a shot point distance and a shot line distance.

In the embodiment of the application, before seismic data acquisition, the computer device can design an observation system according to input work area information, and determine information such as shot position, receiving point position, line number, track number, shot point number, track distance, receiving line distance, shot point distance, and gun line distance, wherein the information is theoretical observation information.

It should be noted that since the shot points cannot be arranged in the obstacle region, if the seismic data acquisition is performed according to the theoretical observation information, data loss, especially loss of the medium-shallow layer, may be caused, thereby affecting the accuracy of the schedule initial velocity inversion. For such a situation, after determining the obstacle area, the computer device adjusts the shot point and the receiving point based on the theoretical observation information to obtain target observation information, and then performs seismic data acquisition based on the target observation information, see step 202 and step 203.

102. According to the theoretical observation information, the computer equipment removes a plurality of first shot points in the obstacle area, increases a plurality of receiving points along the boundary of the obstacle area, increases at least one receiving point arrangement in the obstacle area and increases a plurality of second shot points along the boundary of the obstacle area to obtain target observation information, wherein the number of the second shot points is not less than that of the first shot points, and one receiving point arrangement comprises a plurality of receiving points.

In the embodiment of the present application, the computer device is capable of removing a plurality of shots disposed within the obstructed area on the basis of the theoretical observation information, which will be referred to as a first shot for convenience of description. Then, a plurality of receiving points are added on the boundary of the obstacle area, and at least one receiving point arrangement is added in the obstacle area, namely, a plurality of receiving points are added on the boundary and in the obstacle area. Finally, a plurality of shots, referred to as second shots for ease of description, are added at the boundary of the obstacle area. Wherein the number of shot points added by the computer device is not less than the number of removed shot points. The observation information obtained by the above adjustment is target observation information.

103. And the computer equipment acquires the seismic data according to the target observation information.

In the embodiment of the application, after the computer equipment obtains the target observation information, the computer equipment can acquire the seismic data based on the target observation information, and can effectively make up the missing data of the obstacle area.

Fig. 1 is a main flowchart of a seismic data acquisition method provided in an embodiment of the present application, and steps involved in the seismic data acquisition method are described in detail below on the basis of the main flowchart, and fig. 2 is a flowchart of another seismic data acquisition method provided in an embodiment of the present application, and fig. 2 is an example of a computer device applied in the embodiment of the present application. The seismic data acquisition method comprises the following steps:

201. the computer equipment determines theoretical observation information according to work area information, wherein the work area information is used for indicating a non-obstacle area and an obstacle area, and the theoretical observation information is used for indicating a shot point position, a receiving point position, a line number, a track number, a shot point number, a track distance, a receiving line distance, a shot point distance and a shot line distance.

In the embodiment of the application, before seismic data acquisition, the computer device can design an observation system according to input work area information, that is, the computer device can design an overall theoretical observation system for a work area plane, and output theoretical observation information such as shot position, receiving point position, line number, track number, shot point number, track distance, receiving line distance, shot point distance, and gun line distance. If no obstacle area such as villages, lakes, mountains and the like exists in the work area, the work area surface conditions are simple, and the computer equipment can acquire seismic data based on the theoretical observation information; if a work area has an obstacle area, due to the fact that shot points cannot be arranged in the obstacle area, loss of seismic data can be caused, after theoretical observation information is output by computer equipment for solving the problem, adjustment of the shot points and receiving points can be conducted on the basis of the theoretical observation information, and then seismic data collection is conducted on the basis of the adjusted observation information. The step of adjusting is shown in step 202 to step 208.

For example, if the observation system designed by the computer device is in the form of 32-line 5-shot 400-track orthogonal beams, the theoretical observation information includes shot position, receiving point position, 32 lines received by each shot, 400 tracks per line, 5 shots per beam, track distance of 20 meters, receiving line distance of 200 meters, shot distance of 40 meters, and gun line distance of 200 meters.

202. The computer device removes a first plurality of shots within the obstructed area from the theoretical observation information.

In the embodiment of the present application, since shots cannot be deployed in the obstacle area but only reception shots can be deployed, the computer device removes a plurality of shots located in the obstacle area from the theoretical observation information, and the removed shots are referred to as first shots for convenience of description. Optionally, the computer device is capable of counting a first number of first shots removed.

203. The computer device uniformly adds a plurality of receiving points along the boundary of the obstacle area according to a target track pitch, wherein the target track pitch is not larger than the track pitch.

In the embodiment of the application, the computer equipment can add a plurality of receiving points at the boundary of the obstacle area. Accordingly, the computer device first obtains the boundary of the obstacle area, the boundary being approximately circular or elliptical, and then the computer device uniformly adds a plurality of receiving points along the boundary in a circular manner according to the boundary position of the obstacle area, so that the distance between the receiving points is the target track distance.

For example, the target track pitch is 20 meters, and the computer device uniformly lays a plurality of reception points along the boundary of the obstacle area at intervals of 20 meters.

204. The computer device adds at least one receiving point arrangement in the obstacle area.

In this embodiment of the application, the computer device may obtain, according to the theoretical observation information, a plurality of target theoretical arrangements intersecting the obstacle area, that is, part of the receiving points on the target theoretical arrangements are in the obstacle area, where one theoretical arrangement corresponds to one theoretical arrangement. The computer device can add a receiving point arrangement between every two adjacent target theoretical arrangements, and the length of the receiving point arrangement is not less than the length of the barrier area. Optionally, the increased arrangement distance of the receiving points is the same as the distance between two adjacent theoretical arrangements of the targets. Optionally, the computer device may further add two or more receiving point arrangements between each two adjacent target theoretical arrangements, which is not limited in this embodiment of the application.

For example, the computer device obtains 6 item theoretical arrangements according to the theoretical observation information, and for any two adjacent target theoretical arrangements, the computer device adds one receiving point arrangement between the two adjacent target theoretical arrangements, thereby adding 5 receiving point arrangements. Wherein the village has a maximum length of 1000 m, and each receiving point is arranged between 570 m and 1000 m.

205. And the computer equipment increases a plurality of second shot points along the boundary of the barrier area, wherein the number of the second shot points is not less than that of the first shot points.

In this embodiment, the computer device may uniformly add a plurality of second shot points along the boundary of the obstacle area in a ring manner, and then establish a correspondence between the plurality of second shot points and the receiving points, that is, establish a correspondence between the plurality of second shot points and the original receiving points, and establish a correspondence between the plurality of second shot points and the receiving points newly added in the above step.

206. And the computer equipment determines the modified theoretical observation information as the target observation information, and performs forward modeling on the target observation information to obtain a seismic channel data set.

In the embodiment of the application, the computer device obtains the target observation information after completing the modification of the shot point and the receiving point on the basis of the theoretical observation information. In order to verify the effectiveness of the target observation information, the computer equipment can perform forward simulation on the target observation information through simulation software to obtain an SEGY data set, namely a seismic channel data set in an SEG-Y format.

207. The computer device performs an OVT attribute analysis on the seismic trace dataset.

In the embodiment of the application, different from the existing mode that the OVT elements are divided by the seismic data according to the line spacing of the gun and the receiving line spacing, the computer equipment directly divides the azimuth angle and the offset distance, and simultaneously enlarges the scale of the offset distance and the azimuth angle for multiple times to obtain the macro OVT elements. And then calculating the covering times of all OVT data sets in the effective offset range of the obstacle region and determining whether the distribution of the covering times is uniform. The effective offset range is determined by computer equipment through multiple simulation trial calculations.

For example, the computer device determines the division mode according to the azimuth angle interval of 45 degrees and the offset distance interval of 1500 meters through a plurality of simulation trial calculations. The computer device divides the seismic trace data sets according to the offset range of 0-1500 meters and the azimuth angle of 45 degrees to obtain 4 OVT data sets. The number of coverages and the distribution of the number of coverages for the 4 OVT datasets were analyzed.

It should be noted that, in response to that the coverage times of the OVT data sets are higher and the distribution of the coverage times is more uniform, the computer device determines that the analysis result meets the target condition, and executes step 208; and in response to the fact that the covering times of all OVT data sets are low or the covering times are not uniformly distributed, the computer equipment determines that the analysis result does not meet the target condition, and the computer equipment regenerates the target observation information.

For example, referring to fig. 3, fig. 3 is a schematic diagram illustrating results of an OVT attribute analysis provided according to an embodiment of the present application. The covering times of the 4 OVT data sets are respectively 31 times, 34 times, 32 times and 31 times, and the covering times are uniformly distributed between 25 and 35, so that the computer equipment determines that the covering times of the 4 OVT data sets are higher and more uniform, target conditions are met, subsequent five-dimensional interpolation data processing is facilitated, and offset imaging quality can be improved.

208. And responding to the analysis result meeting the target condition, and acquiring the seismic data by the computer equipment according to the target observation information.

In the embodiment of the application, if the analysis result of the OVT attribute analysis meets the target condition, the computer device can acquire seismic data according to the target observation information, and the acquired seismic data is beneficial to subsequent five-dimensional difference data processing, so that the migration imaging quality is changed.

It should be noted that, in order to make the difference between the seismic data acquisition method provided in the embodiment of the present application and the prior art more obvious, reference is made to fig. 4, where fig. 4 is a distribution comparison diagram of shot points and receiving points provided in the embodiment of the present application. As shown in fig. 4, 401 is a distribution diagram of shots and receiving points of a prior art scheme for compensating for data loss by longitudinally encrypting shots, where an excitation point is a shot. . 402 represents shot and receive point profiles obtained by seismic data acquisition methods provided in accordance with the present application, wherein the characteristic excitation points are second shot points added, the characteristic ring arrangement is a plurality of receive points added at the boundary of the barrier region, and the characteristic ring arrangement is a receive point arrangement added within the barrier region. In addition, fig. 5 exemplarily shows the results of OVT attribute analysis performed on longitudinal observation information obtained by means of longitudinal cryptographic shot in the prior art, as can be seen from fig. 5, the number of coverage times of the 4 OVT data sets shown is respectively 9, 17, 7 and 12, the number of coverage times is distributed between 5 and 25, the variation is very uneven and is in a strip-shaped distribution, and the two directions of north east and north west are most obvious, so that the influence on the azimuthal anisotropy research in the five-dimensional data interpolation regularization and interpretation stage in the processing stage is large, and a large deviation and even an erroneous crack prediction result may be caused. Fig. 6 schematically shows the correspondence between an added set of second shots (in the figure, shot points with receive relationship) and receiving points, the shot points with receive relationship having receive relationship with both the original receiving points and the newly added receiving points.
