地震勘探技术概述
|
摘要
国外经过3/4世纪,国内经过半个世纪,地震勘探技术经历了持续发展和不断进步的过程:从单一地震(地面—地面)到多地震(地面—地面、地面—井孔、井孔—井孔);从单分量到多分量(海底4C、井孔三分量、陆地数字传感器);从一次野外采集到多次时间推移;从早期初级的勘探一体化到采集、处理和解释3个专业方向。在这个过程中,国内外技术水平的差距逐步缩小,而且在很多应用领域,国内目前的技术已经处于领先地位。但是在地震技术研发方面,情况却似乎并非如此,曾经一度缩小的差距正在加大。面对万道单点数字多分量采集技术的重大变化,处理技术的研发成为勘探领域的新课题。一个综合集成的多地震一体化的多分量地震处理技术时代正在到来。
Seismic exploration technology has gone through continuous development and improvement for a half century in China and three-fourth century overseas, which has experienced from single seismic (surface-surface) to multi-seismic (surface-surface, surface-bore hole and bore hole -bore hole), from mono-component to multi component (ocean bottom 4C, bore-hole three component and land digital sensor), from once field acquisition to more time delays and from early exploration generation to that of acquisition, processing and interpretation. The difference of technology in China and overseas is becoming less and less, some in China even keep ahead. However, in research and development of seismic technology, the difference is becoming big once more. With great change of universal channel -single source digital multi-component acquisition technology, the research and development on processing technology becomes a new subject in exploration. Here comes the generation of multi-component seismic processing technology with multi-seismic.
