摘要:

开发一个增强型地质勘探系统,也称为EGS,是一个复杂的过程,取决于地质和操作变量的范围。在环境和地质系统内部和周围的压力被认为是健康的和无害的,或者是暴力的和灾难性的,直接或间接地在环境和地质系统中涉及的不同群体。EGS的利弊一直在讨论和研究一段时间了。本文讨论了EGS工作循环期间和之后的应力重分布相关问题,并为理解基底岩石内部和周围的应力重分布行为提供了新的见解。由于基底岩石与围岩热弹性连接,在地质、设计和操作变量的主要条件下,新产生的应力与现有的原地应力相互作用。还在详细章节中概述了决定EGS连续、安全和高效工作的变量。本文还对EGS中应力再分布的未来研究方向进行了展望。

英文摘要:

Developing an Enhanced Geothermal System, otherwise known as EGS, is a complex process and is dependent on range of geological and operating variables. Stresses in and around EGS are believed to be either sound and non-harming or violent and catastrophic among different groups involved, directly or indirectly, in EGS. Pros and cons of EGS have been under discussion and research for a while now. This paper addresses issues associated with stress redistribution during and after working cycle of EGS and gives a new insight in understanding the behavior of stresses redistribution in and around basement rock. As the basement rock is thermo-elastically connected to the country rock, newly generated stresses interact with the existing in-situ stresses under prevailing conditions of geological, design and operating variables. Variables dictating the continuous, safe and efficient working of EGS are also outlined in detailed sections. Guidelines for future of the research related to stress redistribution in EGS are also part of this paper.
