中、深层地震勘探应用于油田取得显著的成效,已为世所公认。且引用到煤田勘探上也取得一定效果。但是直接将石油物探的中频地震用于解决煤田构造,特别是浅层或小断层构造等问题,尚存在诸多疑难问题不易解决。故近年来不少人提出应用高频地震方法去解决这些问题,某些人对中频地震仪作了改进并进行了野外试验,取得若干成果。然而,何谓高频地震?它的方法特点和仪器技术指标有么什明确的概念呢?现在尚无统一的认识。本文提出一些探讨性看法,与诸位同行共同学习与研究。
It has been recognized in the world that middle and deep seismic exploration is applied to the oilfield to achieve remarkable results. And the reference to coalfield exploration also achieved some results. However, it is not easy to solve many difficult problems by directly using the petroleum geophysical intermediate frequency seismic to solve the problems of the coalfield structure, especially the shallow or small faults. Therefore, in recent years, many people put forward the application of high-frequency seismic methods to solve these problems. Some people made improvements to the intermediate frequency seismographs and carried out field experiments. Some achievements have been made. However, what is the definition of high-frequency earthquakes? What are the characteristics of the method and instrumental specifications? There is no unified understanding. This article presents some exploratory ideas, learning and research with your peers.
