Referring to FIG. 1, a seismic survey data processing method of an embodiment of the application may include the steps of:
s101, obtaining a seismic exploration record file.
In one embodiment of the present application, the obtaining of the seismic survey record file may be, for example, based on receiving raw seismic survey data via a generic data interface. These raw seismic survey data may be standard Seg files, such as Seg-Y files or Seg-D files, and the like.
S102, in the process of writing the seismic exploration record file, extracting first information from the seismic exploration record file, and determining the proportion of abnormal traces; the first information comprises a wire harness number, a total shot number and a total track number.
In an embodiment of the present application, the acquired seismic survey record file may be a seismic survey record file corresponding to each single shot (referred to as a single shot file for short). Each single shot file can have a file header with a fixed length, and the fixed position in the file header has a specific meaning, such as an excitation shot point number, a shot line number, a line beam number, a record length, a sampling rate, a forward playing gain and the like; each single shot file can have files with indefinite length tracks (the length can be identified in the file header section), each track has a fixed-length track header section, and the fixed position in the track header section can have specific meanings, such as line number, pile number, detector embedding state and the like of the track. The head of the trace is followed by all the acquired samples of the trace (the sample length is identifiable in the head). Therefore, the first information of the seismic exploration original seismic data is determined according to the file head and the root mean square value in the seismic exploration recording file.
In one embodiment of the present application, each trace corresponds to seismic wave information picked up by a pile number during a specific time (a preset time, i.e., a collection length) during one shot in a seismic survey collection, so that each trace can calculate a root mean square value (RMS), which is an average energy value of the trace during the shot. When data is written in, the root mean square value of the sampling point is calculated at the same time, the current track is compared with a plurality of tracks (set according to the specific conditions of a work area, such as 3 tracks) in front and at the same time, and when the root mean square value of all the sampling points of the track exceeds a certain range (set according to the specific conditions of the work area, such as +/-10 percent), the track can be considered as an abnormal track. Further, when the root mean square value of a cannon is smaller than a certain value, the cannon can be considered as a waste cannon when the track does not receive seismic data (is out of arrangement or is not passed), and when the abnormal track exceeds a certain range (set according to the specific conditions of a work area, such as 10 percent). In addition, the information such as the abnormal track occupation ratio can be output and displayed in real time according to the requirement.
S103, when the production process information is received, the seismic record files are classified and stored according to the production process information and the first information.
In an embodiment of the application, the production progress information is used for reflecting the progress and the state of seismic exploration production, and is continuously updated along with the passage of time, for example, information such as the number of shots played, the number of lines corresponding to the shots played, the synthetic state of the single shot record, the on-line state of the single shot record, and the processing progress of the single shot record data. Therefore, the seismic record files can be classified and stored according to the production process information and the first information. The classification therein may be preset. In an exemplary embodiment, the seismic record files may be of the following three types:
a seismic record file of the synthesized single shot record;
seismic record files that have entered a designated processing link; and the number of the first and second groups,
a seismic record file that has completed a specified processing session and has been provided for storage by a specified recipient (which may be, for example, a consignor of a seismic survey, etc.).
In an embodiment of the present application, the designated processing link may include data quality control; in another embodiment of the present application, the specified processing element may include seismic profile synthesis; in another embodiment of the present application, the designated processing element may further include data quality control and seismic profile synthesis, i.e., data quality control is first performed, and the seismic profile is synthesized on the basis of the data quality control. In another embodiment of the present application, the designated processing element may further include dividing all the original data according to the arrangement correspondence (for example, according to the excitation valid time), recombining (for example, according to the arrangement track order corresponding to the excitation), calculating (for example, correlating with the true reference signal), arranging (for example, arranging according to the standard SEG file format), and the like. The data processing pressure of the data interpretation center can be favorably reduced by processing of the designated processing link.
In one embodiment of the present application, the sorted storage, for example, the seismic record file for the synthesized single shot record, may be stored in the first data backup module; seismic record files that have entered the designated processing link may be saved in a second data backup module, seismic record files that have completed the designated processing link and have been provided for the designated recipient for saving may be saved in a third data backup module, and so on. The first data backup module, the second data backup module, and the third data backup module may refer to different storage paths (for example, under three folders) on the same storage, or may refer to three storages (for example, a storage of a computer, a storage of B computer, and a storage of C computer).
Therefore, in the embodiment of the application, when the seismic exploration record file is written, first information comprising the wire harness number, the total shot number, the total track number, the abnormal track proportion and the like can be extracted from the seismic exploration record file; when the production process information is received, the seismic record files can be classified and stored according to the production process information and the first information. The data can be directly acquired from the classified data files according to the needs when the subsequent data interpretation center performs data interpretation, data classification and data backup are not needed to be performed on the data, and the data processing pressure of the data interpretation center can be effectively relieved through the preprocessing.
In an embodiment of the application, after the seismic record files are classified and stored according to the production process information and the first information, a data access request of a requester can be received, the requester is subjected to identity authentication, and corresponding data can be accessed only through the identity authentication. In this way, the collected seismic exploration data (including the intermediate data) can be subjected to graded safety management by using different authority levels, so that the data safety is improved.
In an exemplary embodiment of the present application, the privilege levels may be divided into class a, class B, and class C. The type A is the highest authority, and data files in the first data backup module, the second data backup module and the third data backup module can be checked, deleted, copied and cut; the class B is a middle-level authority, and can view the data files in the first data backup module, view, delete, copy and cut the data files in the second data backup module and the third data backup module; the class C is the lowest authority, and can view the data files in the first data backup module and the second data backup module, and view, delete, copy and cut the data files in the third data backup module.
