摘要:

在地震地下流体研究中,区别地下水是受浅层物质补给还是受深部介质活动的影响,是异常核实的主要任务。氢氧稳定同位素技术能够有效地识别地下水的来源与补给过程。文中概述了氢氧稳定同位素方法在地下水异常核实应用中的基本原理、水样采集和测试技术,列举了应用氢氧稳定同位素技术研究井水位升高和水质浑浊异常现象的实例,就氢氧稳定同位素用于核实地下水水位、水温、化学组分和宏观异常进行了简要讨论。该方法的广泛使用,有助于识别地下水异常的构造与非构造影响因素。

Abstract:

Identifying the source of the observed fluid anomalies is a major tast in verifying the anomalies in seismic subsurface fluid research. The stable hydrogen and oxygen isotopes are proved to be effective to trace the underground fluid origin and its development. In this study, we summarized the basic principles, water sampling and testing techniques in recognizing the fluid anomalies by using the stable hydrogen and oxygen isotopes. We also enumerated the related applications in analyzing the sudden water level increase and the rapid shifting from limpid water to murky. The stable hydrogen and oxygen isotopes analysis can be used to verify the macroscopic underground fluid anomalies, such as subsurface water temperature, water level and chemical component changes, and the wide use of this method in seismic subsurface fluid research will be helpful to identify the tectonic or non-tectonic related influencing factors to the fluid anomalies.

Key words: stable oxygen and hydrogen isotopes, the groundwater anomaly, anomaly verification, water-rock interaction, mixing of groundwater
