潜水完整井抽水时水跃值研究

Study on Hydraulic Jump Value at the Pumping of Submersible Full Well

针对艾连别格尔水跃值经验公式,用最小二乘法对其进行修正。通过实例对修正前后两公式进行验证,得出如下结论:艾连别格尔的水跃值经验公式过于保守,误差很大,而经最小二乘法修正后的公式能更好的反应实际情况,误差明显减小。说明修正后的公式更适用于实际工程。

For the formula of the hydraulic jump value,correct by the least squares method.verify two formulas before and after examples of the amendment,the following conclusions： the hydraulic water jump formula is too conservative,the error is large,and was amended by the least squares formula to better reflect the actual situation,error is significantly reduced.It describes that the revised formula is more suitable for practical engineering
