Abstract

The embodiment of the invention provides an inter-seismic source combination excitation optimization method and device. The method comprises steps: at a specified time point, positions of multiple seismic sources meeting a preset excitation condition in a target area are determined; all possible seismic source excitation combinations of the multiple seismic sources at the specified time point aredetermined, the distance between the seismic sources in each seismic source excitation combination is determined according to the position, and according to the distance, one seismic source excitationcombination is selected from all possible seismic source excitation combinations as an optimal seismic source excitation combination; and the excitation sequence in the optimal seismic source excitation combination is determined. Thus, the operation efficiency of the seismic data acquisition can be improved.

Description

technical field [0001] The present application relates to the technical field of multi-source seismic data acquisition, in particular to a combined excitation optimization method and device among seismic sources. Background technique [0002] Seismic data acquisition is the primary work link of oil and gas exploration. With the development of seismic acquisition technology, high-efficiency acquisition technology has been more and more widely adopted by domestic and foreign oil companies. The application of high-efficiency acquisition methods requires more and more acquisition excitation equipment (vibrator), which not only brings more and more challenges to the on-site management of field acquisition and reception equipment, but also poses a challenge to how to collect and excite more scientifically and effectively. Management puts forward higher requirements. [0003] In general, the time-distance rule may need to be satisfied no matter which way the source is excited. Fo...
