许多地震前兆的机理与地球深部流体相关.文章介绍了与此有关的地球深部流体状态的研究进展.通过间接的证据和从若干超深井钻孔探测得到的直接证据,着重介绍了深部水的数量、存在状态和性质,估计地球深部流体孔隙压力和连通性.研究表明,地球深部高温高压状态下的水处于超临界状态,超临界水具有许多特殊性质,这些特殊性质使得流体不仅成为强震前兆的传播媒介和震源破裂过程的影响因素,而且成为直接参与震源动力过程的介质.
The mechanism of many earthquake precursors is related to the Earth’s deep fluids.This paper presents an overview of the research on the deep state of the earth’s fluids.Through indirect evidence and direct evidence from several ultra-deep borehole drilling surveys, the number of deep waters , The state and the nature of existence, and the pore pressure and connectivity of the deep fluid in the earth are estimated.The results show that the water under the condition of high temperature and high pressure in the Earth is in a supercritical state, and the supercritical water has many special properties. These special properties make the fluid not only a precursor to strong earthquakes Of the media and the source of the rupture of the impact of factors, but also become directly involved in the source of dynamical process of media.
