论文摘要
冰岛雷克雅内斯地热场的RN-34孔刺激孔刺激导致井附近的地震活性增加。在这里，我们将其用作案例研究，以研究如何将地震分析与基于物理的模拟研究结合在一起，以进一步了解注射诱导的断层重新激活。这项工作为地震数据提供了新的分析，并应用了最新的模拟软件，用于建模耦合的水力力学过程和由液体注入引起的故障变形。仿真模型基于地质分析的见解，结合了故障网络的明确模型。然后根据注入数据对3D断层储层模型进行校准。尽管数据有限，但该工作表明了如何将地震解释用于开发模拟模型，以及相互建模如何在动力学分析中添加地震解释。
The hydraulic stimulation of the well RN-34 at the Reykjanes geothermal field in Iceland caused increased seismic activity near the well. Here, we use this as a case study for investigation on how seismic analysis can be combined with physics-based simulation studies to further understand injection-induced fault reactivation. The work presents new analysis of the seismic data combined with application of a recent simulation software for modeling of coupled hydromechanical processes and fault deformation caused by fluid injection. The simulation model incorporates an explicit model of the fault network based on geological characterization combined with insights from seismic analysis. The 3D faulted reservoir model is then calibrated based on injection data. Despite limited data, the work shows how seismic interpretations can be used in developing simulation models and, reciprocally, how the modeling can add to the seismic interpretations in analysis of dynamics.
