| 摘 要： | 水位自记井滞后量计算理论是在假定为单管进水口的基础上考虑的，但在实际中的水位自记井大多是复管(多管)进水口，因此，在复管进水口条件下的水位自记井的滞后量计算理论有必要进行研究．从理论方面推导了复管水位自记井滞后量计算公式，考虑到公式的复杂性，采用当量管长法进行简化，并采用修正系数来修正由于简化引起的误差，在一定的范围内简化方法满足精度要求。

| Abstract: | ;The computational theory of delayed quantity in well-logging of hydrographs is based on the hypothesis of singlepipe, but actually most well-logging of hydrographs has multipiple, so it is necessary to study its computational theory.This paper presents the theoretic formula of delayed quantity in well-logging of multipipe hydrograph. Considering the complexity of the formula, a method of equivalent pipe in length was used to simplify it.The error due to the simplification was modified by the coeficient of correction. By computating, the precision of the simplified formula could meet the requirement of application in given range. |
