微地震和地噪声属于被动(无源)地震勘探的两种重要方法,近年来,人们已认识到它们与地热田有密切的关系,虽然许多物理机理目前并没有搞得十分清楚,但开始受到重视并得到越来越广泛的应用。本文简介微地震和地噪声的概念,着重介绍微地震与地热田的关系,应用微地震进行地热勘探的方法和技术。文章力图从震源物理的观点浅解地热田上产生微地震的物理机制,并企图探索微地震、地热田和油气田的关系,期望在扩大能源资源的地震勘探应用范围方面起到“抛砖引玉”的作用。
Microseismic and geo-noise are two important methods of passive (passive) seismic exploration. In recent years, it has been recognized that they are closely related to geothermal field. Although many physical mechanisms are not well understood at present, Emphasis and get more and more widely used. This paper introduces the concepts of microseismicity and ground noise, emphasizes the relationship between microseism and geothermal field, and the method and technology of geothermal exploration using microseism. This paper attempts to explain the physical mechanism of microseism on geothermal field from the point of view of source physics and try to explore the relationship between microseismic, geothermal field and oil and gas field. It is hoped that it will play an important role in expanding the scope of seismic exploration of energy resources.
