摘要
本文较系统地分析了中国地震地下水动态观测网及华北、西南和首都圈等区域井网观测井的地质—水文地质条件、井孔结构、观测项目与方式等对地震前兆反映能力的影响,并通过马17井地应力场的物理与数学模拟、多种条件下的水动力学模型试验及深油井压裂试验观测等进一步论证了分析结果。根据得到的认识,提出了评定观测井映震灵敏性条件的半定量化的方法。
In this paper,the influences of geologic-hydrogeological conditions,structures of wells and observational items or pattern etc. On the capacity of observational wells for reflecting earthquake precursors are analysed for the National Observation Network,and the regional network in North China,Southwest China and the capital area. The obtained results have further demonstrated the physical and numerical simulations of crustal stress field in Ma-17 well area,the hydrodynamical model experiments under various conditions,and the observations of groundwater behaviour during the hydraulic fracturing process in deep oil well.On the basis of the above-mentioned understandings,a semiquantitative method of evaluating sensitivity of the observational wells for reflecting earthquake precursor is proposed.
