钻井对呼和浩特地震台地震观测影响
The effect of drilling on seismic observation of Hohhot Seismic Station
摘要
Abstract
The monitoring ability of seismic stations is not only related to the performance of observational instrument, but also to the background level of environmental disturbance. The power spectrum of noise of the seismic station bases reflected the quality of the foundation and the extent of perturbation. In this paper, we selected the daily 1-hour observation data recorded by JCZ-1T digital seismograph at Hohehot seismic station during the well drilling period of 2015-12-05 to 2015-12-24, which was recorded when the interference was the most intensive and no earthquake was detected. The noise spectrum caused by drilling was then analyzed by Fourier transform method the background noise level of station base and the dynamic range of observational instrument are calculated, and the effects of drilling on seismic observation at Hohhot station was discussed. These results provide a reference for study of the interference of seismic observation environment and also for exploring reasonable and effective measures to eliminate it.关键词
