摘要/Abstract

摘要： 流体在断裂带地震周期中具有重要作用。在地震流体研究中, 该文建议在如下几个方面加强研究力度: ① 断层渗透结构和断裂带古水文地质旋回的研究; ② 断裂带流体循环的尺度效应; ③ 流体分布、循环与构造展布关系; ④ 断裂带深浅部流体关系研究。在断层流体动力学研究中, 建议就某一发震断裂带开展系统研究, 并优先解决以下问题: ① 断裂带流体的起源和成分; ② 产生和维持高孔隙压力的构造环境和水文地质条件; ③ 断裂带及邻近岩体流体运移及重新分布的机制; ④ 取得断裂带孔隙压力变化的数量知识; ⑤ 垂直方向和水平方向流体孔隙压力变化范围; ⑥ 地震周期中流体迁移与孔隙压变化规律。

关键词: 地震流体, 断层渗透结构, 古水文地质, 尺度效应

Abstract: The fluids play an important role in the seismicity cycle of fault zones. The authors put forward several research areas that should be strengthened in the near future in China; ① Fault permeability structure and pale-geohydrological history of fault zone; ② The scale effect on fluid movement along fault zones; ③ The relationship between fluid circulation distribution and tectonic geometry; ④ The relationship between the shallow and the deep fluids. It is suggested that a systemic research work should be done on a specific earthquake fault, and the following topics should be studied preferentially. These are: ① What is the origin and composition of fault zone fluids? ② Identify the range of conditions necessary to develop and maintain elevated fluid pressures; ③ What are the fluid transport mechanisms in and around the fault zone and what physical processes lead to fluid redistribution? ④ Quantify pore pressure spectrum of fault; ⑤ What is the vertical and lateral distribution of fluid pressure regimes; ⑥ What is extent of vertical and lateral fluid migration and pore pressure during a seismic stress cycle?

Key words: Seismological fluid, Fault permeability structure, Pale-geohydrology, Scale effect
