摘　　要：本文对Nakai拟合法作了改进并应用于计算井水固体潮和气压系数。利用该方法还可以计算井水位对固体潮和气压响应的滞后时间。以鲁06井为例,用本文的方法计算出其井水位的固体潮和气压系数分别为16.9mm/10^(-3)和5.58mm/hPa,滞后时间分别为18.8和22.4分钟。校正后的中误差由8.5mm下降到6.1mm。In this paper, the Nakai's fitting method is improved and it is applied to the calculation of tidal and barometric coefficients of the well level. The advantage of this method is that the lag time of the response of the well level to the tide and barometric pressure can be calculated. The well Lu-06 is instanced. We have calculated by this method that the tidal coefficient is 16.9mm/10^(-8), the barometric coefficient is 5.58mm/hPa, their lag time respectively is 18.8 and 22.4 minutes for the well level. The corrected standard deviation decreases from 8.5mm to 6.1mm.
