摘　　要：对横县02号井水位和气压近9个月的观测数据采用小波变换进行长趋势变化和短周期变化的分离,然后利用Clark气压估计方法和固体潮估计方法,对其气压效应和固体潮效应进行深入探讨,分析该井水位微动态信息特征。主要结论如下:(1)井孔具有较高灵敏度,能够观测到井水位的微动态变化。(2)该井气压效率为14.898mm/hPa、固体潮影响系数为-0.1511mm/μGal。本研究计算处理方法对井水位、气压观测数据的长趋势变化和短周期变化的分离效果明显,而且与单纯采用Clark方法相比,可以将气压和固体潮影响系数计算精度提高10%左右,在实际操作性上优于传统回归分析方法。This paper applied wavelet transform to separate variation of long-trend and short period based on the recent 9 months observed data of No.2 well water level at Hengxian County, discussed the well’s air pressure and earth tide by using Clark barometric efficiency and earth tide methods, revealed the micro-behavior information of well water level. The conclusions are drawn as follows:(1) The well is highly sensitive to the observed water micro-behaviors.(2) The barometric efficiency is 14.898 mm/hPa and earth tide affecting coefficient is-0.1511 mm/μGal. The integrated method not only has obvious separating effects, but also improves precision about ten percent compared with the single Clark method. Furthermore, it takes more advantage than the regression methods in operation.
