摘要
采用平滑伪魏格纳分布方法,对内蒙三号地井数字化水位数据进行时频分析结果显示,引起三号地水位变化的主要潮汐分波有M2波、S2波、O1波和K1波,其中M2波的振幅最大。基于卷积回归法得到了该井气压系数和M2波潮汐因子,在此基础上,通过滑动拟合得到了不排水状况下该井的孔隙度和渗透系数。含水层垂直向应力变化量在两次水位下降阶段,所反应的构造张应力现象比较明显。
Using the smoothed pseudo Wigner-Ville distribution method,the digital water level data of the No.3 Well is analyzed. The results show that the main tidal waves which cause the water level of the third floor are M2 wave,S2 wave,O1 wave and K1 wave,and the amplitude of M2 wave is maximal. Based on the convolution method,the gas pressure coefficient and the M2 wave tidal factor are obtained. Based on this,the porosity and permeability of the well are obtained without drainage. It is obvious that the structural tension of the structure is more obvious than that of the water level.
