Abstract:High-dense and uniform spatial sampling technique is both systematical technical countermeasure solving complex issues the seismic exploration faced currently and development trend of seismic exploration ahead.By analyzing the spatial sampling density and distribution of shot and receiver points of seismic acquisition, the paper points out the spatial sampling density and uniformity of distribution are relative to vertical and horizontal resolution of migrated sections, and directly affect the effects of denoise and strength of migration noise.Starting from the angle of data processing,the paper analyzed the action of indoor array on migration processing and points out the high-dense and uniform sampling raw data are very valuable for prestack denoise and migration.The tools such as denoise and indoor array may change the spatial sampling density of raw data,which is valuable and harmless for the follow-up processing.The paper also presents the standards measuring the spatial sampling density and uniformity respectively, and suggests to build up associated appreciate standard of acquisition quality.
