摘要
中国海洋石油领域开展了首次海上多波多分量地震试验。试验效果是不错的 ,主要表现在烃类检测和模糊区成像上。同时充分利用已有资料对方位各向异性进行了初步的研究和探讨。从纵横波剖面的对比和频谱分析结果看 ,浅层横波的纵向分辨率高于纵波 ,中深层二者差不多。我国在多波的基础性研究方面还很欠缺 。
The first offshore multiwave and multicomponent seismic experiment has been made by CNOOC. These experiment results are very encouraging, especially in hydrocarbon detecting and imaging of the seismic obscure zone. The azimuthal anisotropy is preliminarily discussed through the full use of the present data. In view of the seismic event correlation and the p mave and s wave spectrum analysis, the vertical resolution of the s waves is greater than p waves in the shallow horizons and similar in middle deep horizons. The basic study of the multiwave seismic technique is not enough in our country. There should be a lot to be improved.
