本文根据现有的实验资料说明裘布依假定适用于虚构流网,故所得出的自由水面方程和流量方程也应适用于虚构流网。根据虚构流网概念,获得了完整井或非完整井抽水时流量方程。另一方面,用分析方法获得不完整井抽降不大时的流量方程;利用室内实验资料对方程中的参变数值编成曲线图,并说明此方程的精度亦较一些经验公式为高。
According to the existing experimental data, Qiu Buyi is assumed to be suitable for fictitious flow network, so the free surface equation and flow equation obtained should also be suitable for fictitious flow network. According to the concept of fictitious flow network, the flow equation of pumping in the intact or incomplete well is obtained. On the other hand, by using the analytical method, the flow equation of incomplete well pumping down is obtained. Using the experimental data of laboratory, the parameter values in the equation are plotted, and the accuracy of this equation is also higher than that of some empirical formulas.
