Description

Technical Field

[0001] The present invention relates to the technical field of seismic data processing, and in particular to a method, device, computer equipment and storage medium for generating common detection point domain gathers. Background Art

[0002] In the field of seismic exploration, the observation system expresses the mutual positional relationship between the excitation point and the receiving point of the seismic wave. The observation system description file is a file that records such a relationship. They are used to determine which receiving points (detection points) are related to a certain excitation point (shot point). The extraction of the track gather is the process of selecting certain specific recording tracks according to a certain rule. In order to facilitate the stacking and calculation of the velocity spectrum, the stacked tracks of each common reflection point are extracted together according to the observation system and arranged in the order of the shot offset size. This is actually a data rearrangement. In actual seismic exploration construction, the relationship between the shot point and the detection point is many-to-many, that is, one shot point corresponds to multiple detection points, and one detection point can receive data from multiple shot points. The data set of all related receiving points from the same shot point is called a common shot point track gather, and the data set from different shot points for the same receiving point is called a common receiving point track gather. Due to the different spatial geographical locations of each point, the arrival time of the signal from the same shot point is different for different receiving points.

[0003] In actual work, the recording method and format of seismic data used in field acquisition are different from those of indoor seismic data processing systems. In the traditional cable acquisition mode, the data recorded in the field are arranged in time sequence, that is, the first sampling value of each channel is recorded in sequence, and after each channel is recorded, the second sampling value of each channel is recorded in sequence. For common shot point gathers, the seismic data actually collected in the field are usually stored in the form of common shot gathers, so common shot point gathers do not need to be extracted.

[0004] For the actual application scenario of field seismic data acquisition by node instruments, the seismic data collected by traditional cables are stored in the form of common shot gathers. The common shot point gathers collected by traditional means have poor adaptability in the new acquisition mode and low acquisition efficiency. Summary of the invention

[0049] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0050] Embodiment 1

[0051] In this embodiment, Figure 1 As shown, a method for generating a common detection point domain gather is provided, which comprises:

[0052] Step 110, acquiring seismic data, analyzing the seismic data, and obtaining the detection time of each detection data collected at each detection point.

[0053] In this embodiment, the original seismic data is obtained from the detector, and all seismic data files and acquisition node ID sets are obtained. The detection point can also be called a detection point, and the detection data can also be called a detection file. The seismic data includes the detection data of each detection point and the acquisition time of each detection data, and the acquisition time is the detection time.

[0054] In this embodiment, the detection time of each detection data is obtained by analyzing the seismic data, and the obtained detection time is stored in the memory according to the preset structure.

[0056] In this embodiment, the blasting data may also be referred to as a blasting file or a blasting OB file. The blasting OB file is collected and the blasting OB file recorded during the field collection process is parsed to obtain the blasting time of each blasting point, which is the time when the blasting point is fired.

[0057] In this embodiment, the firing data is parsed to obtain the firing time of each firing point, and the obtained firing time is stored in the memory according to a preset structure.

[0058] Step 130, based on the sampling time, according to the detection time and the shot time, sort the detection data and the shot data to obtain a plurality of the shot data corresponding to each detection data, and establish a common detection point domain gather.

[0059] In this embodiment, the sampling time is used as the reference time, the detection data is sorted according to the detection time, and the firing data is sorted according to the shot point time, such as Figure 5As shown, in this way, the corresponding relationship between the detection data and the firing data can be obtained based on the unified reference time. For example, at a certain moment, multiple shot points are simultaneously excited and detected and received by a certain detection point. In this way, it is considered that the data generated by the shot point is received by the detection point. Thus, the correlation relationship between the detection data of the detection point and the firing data of the shot point is established, and then the corresponding relationship between each detection data and the multiple firing data is obtained, thereby establishing a common detection point domain gather.

[0060] In the above embodiment, by respectively acquiring the detection time and the shot point time, the corresponding relationship between the detection data and the firing data can be accurately established, thereby establishing a common detection point domain gather.

[0068] In this embodiment, the firing time of all blasting data is obtained, and the shot line number, shot point number and FFID number of each shot point are obtained. Based on the shot line number, shot point number and FFID number, all shot point times are cycled to determine whether each file meets the time range.

[0070] Based on the sampling time length and the sampling time interval, the detection data and the shooting data are sorted according to the detection time and the shot point time.

[0071] In this embodiment, the time is divided into multiple intervals according to the sampling time length and the sampling time interval. According to the time interval where the detection time and the shot point time are located, the order of the detection data and the blasting data can be determined, and the corresponding relationship between the detection data and the blasting data can be obtained.

[0072] In one embodiment, the steps of acquiring seismic data, analyzing the seismic data, and obtaining the detection time of each detection data collected at each detection point include:

[0073] Acquire seismic data, analyze the seismic data, and obtain the node ID of each detection point; poll each detection point based on the node ID, and collect the detection time of each detection data of each detection point.

[0151] In this embodiment, the blasting data may also be referred to as a blasting file or a blasting OB file. The blasting OB file is collected and the blasting OB file recorded during the field collection process is parsed to obtain the blasting time of each blasting point, which is the time when the blasting point is fired.

[0152] In this embodiment, the firing data is parsed to obtain the firing time of each firing point, and the obtained firing time is stored in the memory according to a preset structure.

[0153] Step 130, based on the sampling time, according to the detection time and the shot time, sort the detection data and the shot data to obtain a plurality of the shot data corresponding to each detection data, and establish a common detection point domain gather.

[0154] In this embodiment, the sampling time is used as the reference time, the detection data is sorted according to the detection time, and the blasting data is sorted according to the shot point time. In this way, the corresponding relationship between the detection data and the blasting data can be obtained based on the unified reference time. For example, at a certain moment, multiple shot points are simultaneously excited and detected and received by a certain detection point. In this way, it is considered that the data generated by the shot point is received by the detection point. Then, the correlation relationship between the detection data of the detection point and the blasting data of the shot point is established, and then the corresponding relationship between each detection data and the multiple blasting data is obtained, so as to establish a common detection point domain gather.

[0155] In one embodiment, when the computer program is executed by a processor, the following steps are also implemented:

[0156] Step 121, obtaining blasting data, parsing the blasting data, and obtaining the firing time of each blasting point.

[0157] Step 122, detecting whether the excitation time is within a preset time range.

[0158] Step 123 : when the firing time is within the preset time range, determining the firing time of the shot point as the shot point time.

[0159] In this embodiment, the firing time of the shot point is obtained, and the firing time is based on the GPS (Global Positioning System) time. It is determined whether the firing time corresponding to each blasting data meets the time requirement. When the firing time is within the preset time range, it indicates that the firing time meets the time requirement, and the firing time is determined to be the shot point time.

[0160] In one embodiment, when the computer program is executed by a processor, the following steps are also implemented:

[0161] Acquire blasting data, parse the blasting data, obtain the shot line number, shot point number, FFID number and firing time of each shot point; poll each shot point based on the shot line number, shot point number and FFID number, and detect whether the firing time of each shot point is within the preset time range.

[0162] In this embodiment, the firing time of all blasting data is obtained, and the shot line number, shot point number and FFID number of each shot point are obtained. Based on the shot line number, shot point number and FFID number, all shot point times are cycled to determine whether each file meets the time range.

[0163] In one embodiment, when the computer program is executed by a processor, the following steps are also implemented:

[0164] Based on the sampling time length and the sampling time interval, the detection data and the shooting data are sorted according to the detection time and the shot point time.

[0165] In this embodiment, the time is divided into multiple intervals according to the sampling time length and the sampling time interval. According to the time interval where the detection time and the shot point time are located, the order of the detection data and the blasting data can be determined, and the corresponding relationship between the detection data and the blasting data can be obtained.

[0166] In one embodiment, when the computer program is executed by a processor, the following steps are also implemented:

[0167] Acquire seismic data, analyze the seismic data, and obtain the node ID of each detection point; poll each detection point based on the node ID, and collect the detection time of each detection data of each detection point.

[0168] In this embodiment, the node ID and the Seis file set under it are circulated to obtain the detection time of each detection data.

[0169] In one embodiment, when the computer program is executed by a processor, the following steps are also implemented:

[0170] The common detection point domain gather is read and input into a visualization interface for display.

[0171] In this embodiment, the common detection point domain gathers are visualized, such as Fig. 6A , Figure 6B and Figure 7 As shown, it is a visualized common detection point domain gather.
