Abstract:As more and more high-density and wide-azimuth seismic surveys have been conducted,the offset vector tile (OVT) has been wiedly applied in seismic data processing and interpretation,and achieved significant results.However,OVT is seldem used in the seismic acquisition.After the introduction to OVT attribute analysis,we define OVT body attributes and OVT tile attributes.Then we use the OVT body attributes and tile attributes in the geometry parameter design,and discuss the influence of field shotpoint offsets on OVT attributes.Based on our apllications,it concludes that offst and azmuth tolerances are sensible to the line spacing of the geometry,and offet shottings deteriorate OVT attributes.
