对东明深井注水恢复试验的解释

INTERPRETATION OF EXPERIMENT OF THE WATER LEVEL RESTORATION AFTER POURING WATER INTO THE DEEP WELL IN SHANDONG'S DONGMING

本文介绍了山东东明井的概况。1987年3月在该井进行了注水恢复试验,将该井含水层理想化为一无限水平承压含水层,根据H.H.Cooper等理论,对这次试验结果进行了处理,求出了东明井含水层的导水系数为8.7×10~9(m^2/s),这比一般含水层低得多。讨论了该井无“微动态”变化的原因,在于其含水层渗透性太差。 注水恢复试验方法为确定水井含水层的导水系数给出了一种简易可行的方法。有了这个系数,对井水位变化的分析提供了一种有用的参数。

In this paper the description of the Dongming well in Shandong Province is given. The experiment of the water level restoration after water injection was conducted in March 1987. In this experiment the aquifer in the well is idealized to be an infinite, horizontal and confined one. The data of the experiment are processed by means of H.H.Cooper's theory. The transmissibility coefficient computed is 8.7* 10 9(m2/s). It is far less than that of a general aquifer. And the cause without 'micro-behavior' variation in the well lies in very low permeability of the aquifer.The method used in experiment of the water level restoration after water injection is a simple and convenient one for estimation of the transmissivity coefficient of an aquifer. This will provide us with a useful parameter for analysis of the water level behavior.
