多分量地震勘探的机遇和挑战

The opportunity and challenge for the multi-component seismic survey.

近年来 ,多分量地震勘探技术发展很快 ,这得益于海上 4C(四分量 )勘探利用PS波资料描述储层上下界面和内部构造细节方面所取得的成功 ;相比之下 ,P波由于受气云的影响 ,成像模糊。面对这种发展趋势 ,国内在海上展开了 4C勘探技术的研究 ,而陆上多分量地震勘探虽未开展此项研究 ,但对此表现出了极大的关注。本文就多分量地震勘探技术在我国陆上石油勘探中所具有的潜能作一初步的探讨 ,以期引起更多的重视 。

The technology of multi component seismic survey has been developed rapidly in recent years and the opportunity is beneficial from the application of marine 4C data, in which PS wave data are used to describe the details of reservoirs structures which were smeared withP wave data because of gas cloud effects.To keep track of the development trend, researches on 4C marine survey have been done in China .We have paid great attention on how to apply this technique to land data. This paper mainly discussed the potentiality of the multi component survey in oil prospecting on land and hopefully it will draw interests from the related specialists so as to step up the development of multi component survey in China.
