Shot point arrangement method and device

Abstract

The invention provides a shot point arrangement method and device, wherein method comprises the steps: acquiring covering times, an offset azimuth coverage needing to be compensated and a offset distance range needing to be compensated of every surface element in a to-be-compensated area in a work area; and encrypting the shot point according to the above values. In the embodiment of the invention, the arrangement of the covering times, the offset azimuth and the offset distance of every surface element is comprehensively considered, the covering times compensation is performed in the offset azimuth coverage and offset distance range, and an optimal encrypted shot point position is automatically obtained. The covering times, and the arrangement of the offset azimuth and the offset distance are considered for the arrangement of the encrypted shot point, therefore the finally obtained compensated work area surface element attributes are more reasonable and reliable than before, so that the redundancy problem of the surface element attributes is solved, the possibility of the appearance of the redundant encrypted shot point is reduced, and the work efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of seismic exploration, in particular to a method and device for laying out shot points. Background technique [0002] In seismic exploration, when an obstacle is detected in the survey area, the corresponding shot point needs to be shifted out of the obstacle area or deleted directly. When the shot point is offset or part of the shot point is missing, the panel attributes of the obstacle area will change to a certain extent, which is manifested in the reduction of local coverage times, missing or uneven distribution of shot detection azimuth and offset. In this case, it is necessary to refine the shot points around the obstacle area to compensate for the changing bin attributes, so as to meet the bin attribute requirements and geological mission requirements. [0003] At present, the shot point encryption is mainly carried out manually, that is, according to the actual requirements of the coverage number d...
