摘要
凤阳地震台TJ-2体积式钻孔应变仪的体应变分量从2023年3月23日开始出现加速下降变化,通过对各种干扰因素和环境变化的调查认为:在凤阳地震台形变井旁边的流体观测井扩孔施工是体应变分量加速向下变化的主要干扰源.通过对2023年6月流体井施工完成后至今一年来凤阳地震台体应变数据进行跟踪分析,认为受打井影响的数据已逐步恢复正常.
Abstract
The body strain component of the TJ-2 volumetric borehole strain gauge at the Feng Yang seismic station started to change in an accelerated downward direction from 23 March 2023.After a detailed investiga-tion of the various disturbing factors and environmental changes,the analysis concludes that the construction of the fluid observation well reaming next to the deformation well of the station is the main disturbing source of the accelerated downward change of the body strain.After tracking and analysing the body strain data of Fengyang Seismic Station for one year since the completion of the construction of the fluid well in June 2023,it is be-lieved that the data affected by the drilling of the well have gradually returned to normal.
