新泽5井数字化水位特征分析

Analysis of the characteristics of digitized underground water level in Xinze No.5 well

分析了新泽5井地下水位、气压、地热(深层水温)等测项的数字化观测资料的特征及其相互间的变化关系。结果表明,数字化水位观测资料与模拟观测资料及其气压效应和潮汐效应一致。给出了数字化水位的气压系数,分钟值、时值、日均值条件下的气压系数分别为7.3mm/hPa、7.4mm/hPa、7.1mm/hPa;M2波潮汐因子和相对误差为0.8011和0.0377;地热变化稳定,与水位呈同步趋势变化。

In this paper, the characteristics of data from digitized observation and correlation of change of underground water level and atmospheric pressure and terrestrial heat are analyzed. The results show that the data of digitized observation on underground water level, including their variation tendency, effects of atmospheric pressure and tidal, are identical with those from simulated observation. The atmospheric pressure coefficient of data from digitized observation on underground water level is presented, atmospheric pressure coefficient of minute value on underground water level is 7.3 mm/hpa, hour value is 7.4 mm/hpa and daily average is 7.1 mm/hpa. Tidal factor of M2 wave is 0.8011 from digitized underground water level, and its relative error is 0.0377. Terrestrial heat variation tendency is identical with underground water level from digitized observation.
