本文提出应用计算机的标准程序来分析阶梯下降抽水试验,既有效又简便。其基本公式为:s=BQ+CQ~D式中 s——井的水位降;Q——井的流量;B——层流水头损失系数;C——紊流水头损失系数;P——扰动强度指数。这些系数测定问题可写成如下的最佳化问 This paper proposes to use the computer’s standard program to analyze the step drop pumping test, which is both effective and simple. The basic formula is: s = BQ + CQ ~ D type s - well water level drop; Q - well flow; B - laminar head loss coefficient; C - turbulent head loss coefficient; P - Perturbation intensity index. These coefficient determination problems can be written as the following optimization questions
