Embodiment two:
For step 100, shot data refers to a record of shot locations disposed at the surface or subsea. In seismic exploration, blasts are typically placed at different locations using equipment such as a blaster source or a vibrating cart, and their location coordinates and firing times are recorded. By controlling the combination of firing time and spatial position, a subsurface source can be created, shock waves can be transmitted into the subsurface, and then seismic signals such as reflection, refraction, etc. of subsurface formations can be recorded. The shot data records the location coordinates of each of the sources of the explosion. These sources of explosion generate seismic waves that propagate through different rock formations in the subsurface and reflect or refract back to the surface. The shot data records the position information of each shot for determining the initial position and propagation path of the seismic wave.
The shot station number in the shot data refers to a unique identifier that numbers or identifies each shot. The shot station number may be a number, letter or a combination of numbers and letters for distinguishing between different shots.
The programming mode of the station number of the shot point can be different according to actual requirements and regulations of exploration companies. Usually, the station number of the shot is compiled according to a certain rule, so that data management and analysis are convenient. For example, it may be organized in geographic order, or according to the needs of the survey project. The function of the shot station number is to uniquely identify each shot, and the corresponding and tracking is convenient during data processing and interpretation. In seismic exploration, shot station numbers are typically stored and used with other attributes of shot data (e.g., shot location, source energy, etc.) to provide complete data information.
For step 200, the geophone data refers to a record of receivers (also referred to as geophones) disposed at the surface or subsea. The geophones are typically arranged around the shot in a grid or line, and they record the received seismic signals. The seismic signals recorded by the geophones include information such as reflected signals, refracted signals, and noise signals from the subsurface formations. The geophone data and shot data together form a seismic recording profile for seismic imaging and geologic interpretation.
The spot number refers to a unique identifier that numbers or identifies each spot. In seismic exploration, the geophone site number is used to distinguish between different geophone locations and receivers.
The method for compiling the detector station numbers can be different according to actual requirements and regulations of exploration companies. Usually, the station numbers of the detection points are compiled according to a certain rule, so that data management and analysis are convenient. For example, it may be organized in geographic order, or according to the needs of the survey project.
The function of the detector station number is to uniquely identify each detector, and the detector station number is convenient to correspond and track during data processing and interpretation. In seismic exploration, the geophone site number is typically stored and used with other attributes of the geophone data (e.g., the position of the geophone, the seismic signal recording, etc.) to provide complete data information.
For step 300, the seismic observation system refers to an arrangement that describes the relative spatial positional relationship between an array of excitation points and reception points in a seismic survey. Different seismic exploration methods employ different observation systems.
From the view of the type of receiving the seismic waves, the observation system can be divided into a refraction wave observation system, a longitudinal wave observation system, a transverse wave observation system and a converted wave observation system, from the view of the observation space, the observation system can be divided into a two-dimensional seismic observation system and a three-dimensional seismic observation system, and from the view of the observation mode, the observation system can be divided into a simple continuous observation system and a multiple coverage observation system. The choice of which seismic observation system depends on the seismic exploration task, the seismic geologic conditions of the detection zone, the quality of the data, the capacity of the seismic equipment, and the exploration cost. For example, in each stage of seismic exploration overview, general investigation and detailed investigation, different observation systems should be selected, namely a two-dimensional seismic observation system is mainly adopted in the overview and general investigation stages, the coverage times can be appropriately higher for areas with low signal to noise ratio, and a three-dimensional seismic observation system is mainly adopted in the detailed investigation stage, wherein the coverage times and the bin size are determined by geological tasks.
Whether two-dimensional or three-dimensional seismic exploration, multiple coverage observation systems are employed, three basic types:
(1) The excitation point is in the center of the arrangement and is called a symmetrical observation system;
(2) An asymmetric observation system (the number of receiving channels at two sides of a shot point is not equal) is called as an excitation point which is not in the center of the arrangement;
(3) The shot is arranged at the end point and is called a unilateral observation system. With the continuous development of seismic exploration technology, the types of seismic observation systems are also various, and details are seen in a two-dimensional seismic observation system and a three-dimensional seismic observation system.
The basic parameters of the earthquake observation system include the track distance, the surface element, the coverage times, the offset distance, the shot point distance, the receiving line distance and the shot line distance. The observation system is generally represented by a graphic method, mainly sometimes a distance-from-plane method and a comprehensive plane method. The time interval plane method is to show the observation sections corresponding to different shots on a plane diagram in a time interval curve mode. In a simple case, for example, the reflection interface is a single level or inclined plane, the reflection wave from the same interface can be clearly represented, but the position of the observation area cannot be correctly reflected in a complex observation system. The comprehensive plane method is to show the relative spatial position relation of the excitation point and the receiving point and the observed area on the plane diagram according to the same principle as the time interval plane method. The method for representing the comprehensive plan is to scale the exciting points and receiving points distributed on the measuring line according to a certain proportion, and then make 45-degree line from each exciting point to the receiving arrangement direction. The oblique line is called a common gun point line, projection is carried out on the oblique line from a receiving point to the oblique line, the projection line from a detection point is called a common receiving point line, and the intersection point of the two is called a common reflection point. The observation area is then the distance between the projected points of the different common reflection points into the line. The offset distribution and the number of times of coverage of each reflection point can be seen from the integrated plan view. Integrated planograms are often used in two-dimensional seismic exploration to design analytical seismic observation systems. In three-dimensional seismic exploration, a three-dimensional observation system usually displays the three-dimensional observation system on a plane according to the coordinates of offset points, and a comprehensive plane diagram is still adopted to analyze the distribution condition of offset, azimuth and coverage times of each line in the three-dimensional observation.
In the implementation of step 300, firstly, the relation between the identifier of each data in the original shot point data and the shot point station number and the relation between the identifier of each data in the original detector point data and the detector point station number are required to be determined, then the calculation parameters of the seismic observation system are calculated, then the calculation parameters are used for carrying out the loading grid operation, and the information such as the track distance, the surface element, the coverage times, the offset distance, the shot point distance, the receiving line distance, the shot line distance and the like is calculated on the basis, so that the seismic observation system corresponding to the original shot point data and the original detector point data is determined.

Each detector has a unique detector number for uniquely identifying the position information of the detector.

Wellhead time refers to shot triggering time recorded in a seismic survey. This time refers to the exact moment of triggering the shot at the wellhead for comparison and synchronization with the triggering times of the other detectors.
The explosive quantity refers to the explosive quantity used by shot points in seismic exploration. The explosive amount can influence the energy release of seismic waves, and has important influence on the quality and interpretation of seismic exploration data.
