The technology related to the embodiments of the present application is described below.
Near-surface velocity modeling is an important link in land seismic data processing. The accuracy and resolution of the near-surface velocity model directly affect the accuracy and effect of subsequent static correction, velocity analysis and offset imaging. The shallow velocity structure within 500 meters of the near-surface can be reflected by utilizing the information of the first arrival wave of the earthquake.
Forward modeling (forward modelling): in geophysical prospecting research, theoretical values (mathematical simulation) of a geologic body are calculated by constructing a mathematical model according to the shape, shape and physical property data of the geologic body, or numerical values (physical simulation) of geophysical effects generated by observing the model by constructing a physical model are called forward modeling. In the process of explaining the geophysical data, the forward modeling result is often used for comparing 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 objective reality. This process of comparison is also called a selection method.
The SEGY is that the seismic data is generally organized by taking the seismic channel as a unit 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 Geophysicists), which is one of the most common formats for 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, an embodiment of the present application is described by taking a computer device as an example. The seismic data acquisition method comprises the following steps:
101. The computer device determines theoretical observation information based on the work area information for indicating the non-obstacle area and the obstacle area, the theoretical observation information for indicating the shot point position, the receiving point position, the line number, the track number, the shot point number, the track distance, the receiving line distance, the shot point distance, and the shot line distance.
In the embodiment of the application, before seismic data acquisition is performed, the computer equipment can perform design of an observation system according to input work area information, and determine information such as shot point positions, receiving point positions, line numbers, channel numbers, shot point numbers, channel distances, receiving line distances, shot point distances, shot line distances and the like, wherein the information is theoretical observation information.
It should be noted that, because the shot cannot be arranged in the obstacle region, if seismic data acquisition is performed according to theoretical observation information, data loss, especially loss of the middle and shallow layers, is more prominent, and thus the accuracy of the primary speed inversion of the schedule is affected. For this case, after determining the obstacle region, the computer device adjusts the shot point and the receiving point based on the theoretical observation information, thereby obtaining the target observation information, and then performs seismic data acquisition based on the target observation information, see step 202 and step 203.
102. The computer equipment removes a plurality of first shots in the obstacle area according to the theoretical observation information, adds a plurality of receiving points along the boundary of the obstacle area, adds at least one receiving point arrangement in the obstacle area, and adds a plurality of second shots along the boundary of the obstacle area to obtain target observation information, wherein the number of the second shots is not less than that of the first shots, and one receiving point arrangement comprises a plurality of receiving points.
In the embodiment of the application, the computer device can remove a plurality of shots arranged in the obstacle region based on the theoretical observation information, and the shots are called as first shots for convenience of description. Then, a plurality of receiving points are added on the boundary of the barrier zone, and at least one receiving point arrangement is added in the barrier zone, namely, a plurality of receiving points are added on the boundary and the inside of the barrier zone. Finally, a plurality of shots are added at the boundary of the obstacle area, and the shot is called a second shot for convenience of description. Wherein the number of shots added by the computer device is not less than the number of shots removed. Through the adjustment, the obtained observation information is the target observation information.
103. And the computer equipment collects 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.
In the embodiment of the application, a seismic data acquisition method is provided, more shots and receiving points are added on the boundary of an obstacle region, and at least one receiving point array comprising a plurality of receiving points is added in the obstacle region, so that each OVT gather in the effective offset range of the obstacle region has a certain coverage frequency and is uniform, subsequent five-dimensional interpolation data processing is facilitated, offset imaging quality is improved, and the requirement of pre-stack inversion is met.
The foregoing fig. 1 is a main flowchart of a seismic data acquisition method provided in an embodiment of the present application, and on the basis of the main flowchart, the steps involved in the seismic data acquisition method are described in detail, with reference to fig. 2, and fig. 2 is a flowchart of another seismic data acquisition method provided in an embodiment of the present application, as shown in fig. 2, and in the embodiment of the present application, an application to a computer device is described as an example. The seismic data acquisition method comprises the following steps:
201. the computer device determines theoretical observation information based on the work area information for indicating the non-obstacle area and the obstacle area, the theoretical observation information for indicating the shot point position, the receiving point position, the line number, the track number, the shot point number, the track distance, the receiving line distance, the shot point distance, and the shot line distance.
In the embodiment of the application, before seismic data acquisition is performed, the computer equipment can perform design of an observation system according to input work area information, namely, the computer equipment can perform integral theoretical observation system design on a work area plane, and theoretical observation information such as shot point positions, receiving point positions, line numbers, channel numbers, shot point numbers, channel distances, receiving line distances, shot point distances, shot line distances and the like is output. If no obstacle area exists in the work area, such as villages, lakes, mountains and the like, the ground surface condition of the work area is relatively simple, and the computer equipment can acquire seismic data based on the theoretical observation information; if a barrier area exists in the work area, the barrier area cannot be internally provided with shot points, so that the defect of seismic data information can be caused, after the computer equipment outputs theoretical observation information for solving the problem, the adjustment of the shot points and the receiving points can be carried out on the basis of the theoretical observation information, and then the seismic data acquisition is carried out on the basis of the adjusted observation information. The steps of adjustment are referred to in steps 202 to 208.
For example, the observation system designed by the computer equipment is in a form of a 32-line 5-gun 400-channel orthogonal beam, and the theoretical observation information comprises a gun point position, a receiving point position, 32 lines received by each gun point, 400 channels of each line, 5 gun points per beam line, 20 meters of track distance, 200 meters of receiving line distance, 40 meters of gun point distance and 200 meters of gun line distance.
202. The computer device removes a plurality of first shots within the obstacle region from the theoretical observation information.
In this embodiment of the present application, since the shots cannot be laid in the obstacle region, only the receiving points can be laid, the computer device removes the shots located in the obstacle region 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 removed first shots.
203. The computer device uniformly increases a plurality of receiving points along the boundary of the obstacle region according to a target track pitch, the target track pitch being no greater than the track pitch.
In the embodiment of the application, the computer equipment can increase a plurality of receiving points at the boundary of the obstacle region. Correspondingly, the computer equipment firstly acquires the boundary of the barrier zone, wherein the boundary is approximately circular or elliptical, and then uniformly increases a plurality of receiving points along the boundary in an annular mode according to the boundary position of the barrier zone, 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 distributes a plurality of receiving points along the boundary of the obstacle region at intervals of 20 meters.
204. The computer device adds at least one array of receiving points within the obstacle region.
In this embodiment of the present application, the computer device may obtain, according to the above theoretical observation information, a multi-item target theoretical arrangement intersecting with the obstacle region, that is, a portion of receiving points on the target theoretical arrangement are in the obstacle region, where one theoretical arrangement corresponds to one. The computer device can add a receiving point arrangement between each two adjacent target theoretical arrangements, and the length of the receiving point arrangement is not less than the length of the barrier region. Optionally, the distance between the two adjacent target theoretical arrangements of the increased receiving points is the same. 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 present application.
For example, the computer device obtains 6 target 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, so as to add 5 receiving point arrangements. Wherein the maximum length of village is 1000 meters, and the length of each receiving point is 570-1000 meters.
205. The computer equipment increases a plurality of second shots along the boundary of the obstacle region, and the number of the second shots is not less than that of the first shots.
In this embodiment of the present application, the computer device may uniformly increase a plurality of second shots along the boundary of the obstacle area in an annular manner, and then establish a correspondence between the plurality of second shots and the receiving points, that is, establish a correspondence between the plurality of second shots and the original receiving points, and establish a correspondence between the plurality of second shots and the receiving points newly added in the foregoing step.
206. The computer equipment determines the modified theoretical observation information as the target observation information, and forward modeling is carried out on the target observation information to obtain a seismic trace data set.
In the embodiment of the application, the computer equipment obtains the target observation information after finishing the modification of the shot point and the receiving point on the basis of the theoretical observation information. In order to verify the validity of the target observation information, the computer equipment can conduct forward modeling on the target observation information through simulation software to obtain an SEGY data set, namely an SEG-Y format seismic trace data set.
207. The computer device performs OVT attribute analysis on the seismic trace data set.
In the embodiment of the application, unlike the conventional mode of dividing the OVT elements by the offset and the receiving offset of the seismic data, the computer equipment adopts azimuth angles and offset to directly divide, and simultaneously enlarges the offset and azimuth angles for multiple times to obtain the macro OVT elements. And then calculating the coverage times of all OVT data sets in the effective offset range of the obstacle area and determining whether the coverage times are uniformly distributed. Wherein the effective offset range is determined by the computer device through multiple simulation trial calculations.
For example, the computer device determines the division at azimuth intervals of 45 ° and offset intervals of 1500 meters through multiple simulation trials. The computer device divides the seismic trace data set by 45 azimuth in the range of offset 0 to 1500 meters to obtain 4 OVT data sets. The number of coverage and coverage distribution of the 4 OVT data sets were analyzed.
It should be noted that, in response to the coverage times of each OVT data set being higher and the coverage times being distributed more uniformly, the computer device determines that the analysis result meets the target condition, and executes step 208; in response to the lower number of coverage times of each OVT dataset or uneven coverage times distribution, the computer device determines that the analysis result does not meet the target condition, and the computer device regenerates the target observation information.
For example, referring to fig. 3, fig. 3 is a schematic diagram of a result of OVT attribute analysis provided according to an embodiment of the application.
