多分量地震的装备

Equipments for multi-component seismic exploration.

多分量地震技术是当前地震技术发展的一个热点 ,被评价为地震工业的第四次技术革命 ,其中最主要的原因是该项技术与单分量地震相比 ,会使地震技术的应用产生一些根本性的变化 ,从而获得巨大的经济效益。文章从多分量地震技术所涉及的硬件出发 ,重点介绍了目前国内外最新的海上多分量地震仪器装备 ,包括 :四分量检波器、数字包、海底电缆、定位系统、中心站 (控制和记录系统 )及震源系统等 ,同时还列出了部分性能指标及制造难点。多分量地震装备的研制和开发是发展多分量地震技术的关键步骤。

The multi component seismic exploration,being appraised to be the fourth technological revolution in seismic industry,is one of the hot spots in seismic techniques. The most important reason is that this technique makes the seismic application changed fundamentally and may acquire great economic profit compared to the conventional seismics. The paper introduces the newest seismic data acquisition instrument for ocean multi component seismic exploration,including the four component geophone,digitizer,ocean bottom cable,position system,recording system and source system. The partial technique parameters and difficulties for manufacturing of the instrument are also pointed out. As a result,it can be concluded that the manufacture and development of the multi component instrument is the key step for developing the multi component seismic technology. Subject
