OVT属性分析方法在采集设计中的应用
|
摘要
OVT(Offset Vector Tile,炮检距矢量片)技术广泛应用于高密度、宽方位地震资料处理、解释中,并取得良好效果。但该技术在地震数据采集领域应用较少。本文介绍了OVT属性分析技术,给出OVT体属性、片属性定义;将此两种属性应用于观测系统参数论证中,并讨论数据采集现场变观对OVT属性的影响。通过实际应用并对比分析得知:OVT属性中炮检距容差和方位角容差对于观测系统的线距较敏感,可用于对比、评价不同观测系统的优劣;采集现场炮点变观后的恢复性激发方法给地震数据OVT属性带来负面作用,应尽量避免采用此种方式。
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.
