摘　　要：本文给出了一种计算考虑滞后影响的井水位固体潮系数的新方法。导出了计算固体潮系数和滞后时间的公式,给出了考虑滞后影响的井水位固体潮校正公式。以鲁07井为例,用该法求出其井水位固体潮系数为16.5mm/10^(-8),水位对固体潮响应的滞后时间为0.48小时。与以前的回归分析方法相比,校正后的水位中误差明显减小,校正效果比较好。In this paper, a new method of calculating the lag influ-ence of the tidal coefficient in the well level is given. The formulas of calculating the tidal coefficient and lag time are developed, and the corrected formulas of lag influence of tide in the well level are given. The well Lu-07 is instancied.By using this method,we have calculated that the tidal coefficient of the well level is 16.5mm/10-8 and the lag time of the response of water level to the tide is 0.48 h. The standard deviation of the water level corrected by the tide evidently decreases and the results of the water level are better than the former method of the regression analysis.
