宽方位三维观测系统的发展现状与趋势
|
摘要
通过分析对比目前生产实践中所使用的几种常见的窄方位与宽方位观测系统、多接收线与重复炮点的宽方位观测系统、陆上水网地区与滩浅海过渡带的宽方位观测系统的参数与属性,说明了三维地震采集宽方位观测系统是现在乃至今后一定时期内应该大力推行的技术。提出了对于道距、线距和炮点距完全规则相等的全方位三维采集观测系统的理想目标,认为海底电缆(OBC)技术、陆上万道采集系统、微机集群技术的推广使全方位、高密度及高覆盖观测系统的三维地震数据采集成为可能。
In view of some analyses and comparisons on parameters and attributes of several kind of common inspection system used in production practice at present, such as wide-azimuth and narrow-azimuth inspection system, multi-line receive and repeat shot points wide-azimuth inspection system, land water system area and shallow-beach transitional zone wide-azimuth inspection system, the authors indicate the wide-azimuth inspection system of the 3D seismic data acquisition is a technology which at present and even the certain time in future should be supposed to popularize massively. It is put forward that the most ideal target is the omni-directional 3D seismic acquisition inspection system in which, the trace-spacing, the receive line-spacing and the shot point-spacing are completely regular and equal, and it is indicated the popularization of the ocean bed cable (OBC) technology, ten-thousand-trace acquisition system in land and PC cluster technology will make the 3D seismic acquisition of the omni-directional, the high density and the high cover inspection system possible.
