摘要
本文给出一种用褶积滤波处理井水位对气压响应滞后的新方法,考虑了气压对井水位“记忆”影响的特点,对水位的气压改正采用了非线性的处理方法。用新方法对鲁03井进行气压改正后的平均中误差为0.65cm,而用一般相关方法则为1.96cm。最后讨论了褶积滤波积分区间长度与水井含水层系统性质的关系。含水层的导水系数越小,井孔截面积越大,则这个区间越长。
In this paper,a new method is given that the faltung filtering is used for correction of the response lag of well water level to barometric pressure. Considering the characteristic of the 'memory' effect of barometric pressure on well level, the nonlinear handling method is adopted for correction of the barometric pressure of water level. Taking the well Lu-03 for instance, the average standard deviation of correction for barometric pressure of the well wáter level by the general regression is 1.96cm,but that by the new method is only 0.65cm. The result shows that the new method is better than the former one. Besides, the relation between the integral interval length of faltung filtering and the character of well aquifer system is discussed. The less the transmissibility of the aquifer, the bigger the section area of the well easing, the interval iength is longer.
