过去的 10年 ,广泛的技术创新带来了油气储量勘探和开发方法的巨大进步。其中的一个主要例子就是在海上石油与天然气勘探中采用横波对气云下方的反射层进行了成像。这项技术在 2 0世纪 90年代完成了从发展初期到走向成熟的过程 ,现在已整合到各种商业处理软件包中 ,并在许多情况下得到了成功应用。最近一次SEG年会和本期《TLE》专集 (即 2 0 0 1年 9月出版的《TLE》———译者注 )记录了许多转换波 (P SV)的应用实例。然而 ,能源工业界对SH波 (另一种类型的横波 )的研究却很少。与此相反 ,SH波的近地表应用却受到了越来越多的关注。本文简要地回顾了过去 10年中能源工业在横波技术方面取得的进步 ,这些进步为目前SH波在近地表的应用开辟了途径。本文以未固结淤积环境为例 ,说明对P波和SH波资料进行综合解释的优越性
Over the past 10 years, a wide range of technological innovations have brought tremendous advances in oil and gas exploration and development methods. A prime example of this is the use of shear waves in the offshore oil and gas exploration to image the reflector beneath the gas cloud. The technology, which matured from its infancy through maturity in the 1990s, has now been integrated into a variety of commercial processing packages and has been successfully deployed in many cases. The most recent SEG Annual Meeting and the current issue of TLE (ie, “TLE”, September 2001) note many examples of applications of P-SV. However, few studies have been conducted on the SH wave (another type of shear wave) in the energy industry. In contrast, the near-surface application of SH waves has received more and more attention. This article briefly reviews the energy industry’s advances in transverse wave technology over the past decade that have opened the way to the near-surface applications of SH waves today. In this paper, unconfined siltation of the environment, for example, explain the P wave and SH wave data comprehensive interpretation of the superiority
