| 摘 要： | 随着多道遥测地震仪和三分量数字检波器的问世及数字处理和资料解释技术的进步，众多欧美大学、研究所及油气公司的地球物理学者针对多波地震勘探理论、资料处理模块、纵波对比试验等开展了大量的研究工作。目前深层横波震源技术尚不成熟，大量的多波技术研究仍然是针对转换波。为保证纵波资料质量，一些项目将传统检波器获得的纵波资料与三分量获得的纵波资料进行对比，即用三分量数字检波器采集的同时，仍用传统纵波检波器进行采集。此外，与三维三分量地震勘探相配套的三维多波VSP技术等也处于研究之中。

European and American Status Quo of Applied Geophysics -Multiwave Seismic Prospecting |
| |
| Abstract: | Following the multichannel telemetering seismograph and three component digital geophone made appearances, as well as progress in digital data processing and interpretation, a lot of geophysical scholars from European and American universities, research institutes and oil and gas companies aimed at multiwave seismic prospecting theories, data processing modules, compression wave comparison testing etc. carried out abundant research efforts. At present, the deep shear wave source technique is still in juvenility, major multiwave technical studies are directed against transformed waves. For assurance of compression wave data quality, some research items made comparison between compression wave data from traditional geophones and from three component digital geophones, thus the data acquisition is from the two kinds of geophones simultaneously. Besides, the matching 3D multiwave VSP technique to the 3D three component seismic prospecting research is also in progress. |
