鲁03井水位滞后于气压的处理

DATA PROCESSING OF WELL LU-03 IN PHASE LAG OF WATER LEVEL TO BAROMETRIC PRESSURE

摘要:

本文给出了一种处理井水位对气压影响滞后的方法,同时给出了计算公式。以鲁03井为例,用这种方法求出其井水位气压系数为6.41mm/hpa,水位对气压响应的滞后时间为1.52小时。该方法排除气压影响的效果较好,水位的气压校正中误差明显减小。

Abstract:

In this paper, a new processing method of phase lag of response of water level to barometric pressure is given. The formulae for calculating the barometric coefficient and lag time of the well level in consideration of lag influence are given. Taking well Lu-03 as an example, by using the new method, it is obtained that the barometric coefficient is 6.41 mm/hPa and the lag time of the response of well level to barometric pressure is 1.52h. The standard deviation of the water level corrected by barometric pressure decreases obviously.
