摘　　要：本文介绍了鲁07井管径变化对固体潮响应的观测情况,通过对在不同管径中的水位分别做调和分析,得出了管径变化对潮汐振幅影响不大,而对位相有3.8°滞后的结果.然后从理论上计算了这种影响,理论结果和观测结果符合得相当好.并讨论了井水位固体潮系数和响应位相滞后与井径及干扰周期之间的关系.In this paper the observations of response to earth tide in different radius in the well province Shandong No.7 are given. On the basis of the harmonic analyses of the water levels in different radius of the well it turns out that the variation of the radius in the well less affects amplitude of the water level tide and this variation affects a phase lag about 3.8 degrees. Then the effect was calculated by theory too. The theoretical conclusions are accorded with the observations quite well. The relationships between the well tidal coefficient and the phase lag of the response to the earth tide, the radius in the w.ell and the periods of the disturbance, are discussed.
