基于钻孔特性的体应变观测相关性研究
Study on Correlation of Volume Strain Observation Based on Borehole Features
摘要
Abstract
Fifteen volume strain observation points were established in Jiangsu province during the construction of the Jiangsu digital seismic precursor network.However,the stability of observa-tion data obtained from these points is influenced by differing installation times,geographical po-sitions,geological conditions,and drilling features.Regression and harmonic analyses have been used in this study to discuss the observed data of volume strain in Jiangsu province;further,the variation characteristics of observed data obtained from different stations have also been analyzed. In combination with borehole histogram and the running status of instruments,the relation among the tidal factor of the M2wave,regression coefficients of pressure and water level,litholo-gy,and borehole features are analyzed.In addition,effective measures that can improve the quali-ty of volume strain observation are discussed.关键词
