深井水位固体潮的调和分析结果

THE HARMONIC ANALYSIS RESULTS OF THE WELL TIDES IN DEEP BOREHOLES

使用Venedikov调和分析方法,对8口深井各一年或两年经气压改正后的水位记录,计算了水位固体潮相对于体应变固体潮的振幅比和相位差。本文从相位差的分析结果求解了含水层的渗透率,分析结果还显示出液态地核动力学效应引起的固体潮日波振幅比的共振现象。这是对以往其它观测手段得到的相应结果的支持,同时也说明了深井水位资料中含有非常丰富的地球物理信息。文中还对环境因素和井孔条件造成的某些效应做了探讨。

The amplitude ratio and the phase shift of the well tides have been calculated versus the volumetric tidal strain by using of Venedikov harmonic analysis method to one or two years air-pressure-corrected water level records of eight deep boreholes.In this paper,we are trying to get the permeability of the aquifer from the analysis results of the phase shift,The analysis resuIts have also displayed the resonance phenomena of the diurnal waves amplitude ratio caused by the dynamic effects of the liquid earth core.It gives supports to the relevant results obtained by other kind of observation,and demonstrated that there are plenty geophysical information contained in the water level data of the deep boreholes.Some effects caused by the enviromment factors and the borehole condititons have also been discussed in this paper.
