由流体的注入和采出所诱发的地震活动已成为一个围绕地下水资源和能源的科学讨论热点。本文展示了流动和地质力学耦合的模拟技术在2012年5月意大利北部卡沃内油田附近发生的破坏性地震(MW6.0和MW5.8)序列的震后分析中的应用。该序列引发了一个问题:这些地震是否可能由石油和天然气生产活动诱发。本文的分析强有力地表明,卡沃内油田流体的采出和注入的联合效应并不是观测到的地震活动的诱因。更普遍地,本文研究表明耦合流动和地质力学的计算模型可将地质、地震构造、测井、流体压力、流动速率和大地测量数据整合,并为评估和管理与诱发型地震活动相关的危害提供一种有希望的方法。
Seismic activities induced by the injection and extraction of fluids have become a hot topic of scientific discussion around groundwater resources and energy sources. This paper presents the application of simulation of flow and geomechanical coupling in the post-earthquake analysis of the devastating earthquakes (MW 6.0 and MW 5.8) sequences that occurred near the Carbone oil field in northern Italy in May 2012. The sequence raises the question of whether these earthquakes are likely to be induced by oil and gas production activities. The analysis in this paper strongly suggests that the combined effect of fluid production and injection in the Carbone oil field is not an incentive for observed seismicity. More generally, the present study shows that computational models of coupled flow and geomechanics can integrate geologic, seismotectonic, well logging, fluid pressure, flow rates, and geodetic data and provide a basis for assessing and managing hazards associated with induced seismicity A promising method.
