When the trace gather needed for extracting, the channel number for the big gun inspection pair that each shot point is included can be calculated in single-shot data
Road serial number, extract corresponding seismic channel, by offset distance from small to large sequence recombination save as SEG-Y file, be used in combination
Geotoolkit component is shown.
It is to limit on the basis of total excitation point trace gather plus offset distance that selection shot point, which extracts common offset trace gather, is extracted every
It is immediate together with given offset distance in all roads of a shot point, if there is twice offset distance is identical and closest to given
Offset distance is then chosen lesser that one of big gun wire size.
It selects shot point to extract orientation angle gathers principle altogether and extracts all of each shot point as extraction common offset trace gather
It is immediate together with that with given azimuth in road.
In the embodiment of the present application, the specified big gun that the index and shot point for establishing the specified big gun inspection pair that shot point includes include is examined
Incidence relation between is examined to other big guns, can quickly find specified big gun inspection pair, and according to the incidence relation, Ji Kezhi
The information for obtaining all big guns inspection pair for taking shot point to include saves acquisition shot point without traversing all big guns inspection pair in work area
The time of the information for the big gun inspection pair for including, improve the efficiency that seismic observation system attributive analysis is carried out to shot point.
If target object to be analyzed is receiving point, it is step 301 that step 101 to step 104, which can correspond to execution,
To step 304, step 105 can be executed as step 305 to step 307.As shown in figure 3, the method comprising the steps of 301 to step
307:
Step 301, the information for obtaining receiving point.
Wherein, the information of receiving point includes the reception wire size of receiving point, receives point number and receiving point index.
RcvLineSet.ar file is traversed, receiving point relevant information is read out, and is stored in memory, wherein connect
The information of sink further include all reception lines, every receive the line receiving point that is included.
Step 302, according to the reception wire size of receiving point, receive point number and receiving point indexes, determine that receiving point includes the
The index of two specified big gun inspections pair.
Step 303, according to the index of the second specified big gun inspection pair, obtain the geophone offset of the second specified big gun inspection pair, azimuth, logical
Taoist monastic name and the second incidence relation.
Step 304, according to the second incidence relation, obtain the information for other big guns inspection pair that receiving point includes.
The intended recipient point is inquired from memory according to the reception wire size of intended recipient point, reception point number, receiving point index
The specified big gun inspection of include second is to the index in srpair.pair file, according to the second incidence relation, from srpair.pair
Associated big gun inspection pair is traversed in file, is stopped until searching all big guns inspection clock synchronization for including with the intended recipient point.
The quantity for the big gun inspection pair that step 305, statistics receiving point include, and calculate the channel number for the big gun inspection pair that receiving point includes
Road serial number in single-shot data.
Step 306, the quantity of big gun inspection pair, the geophone offset of big gun inspection pair and the azimuth for including according to receiving point, draw and receive
Point attributed graph.
Receiving point attributed graph includes geophone offset and midpoint number figure, azimuth and midpoint number figure, geophone offset and midpoint
