摘　　要：通过分析承压井孔储水效应对井水位固体潮效应(井潮)的影响,重点研究了含水层储水系数S和导水系数T对潮汐排水响应的影响,以探讨井潮变化形成的初步原因.以川06井为例,通过对实测井孔水位数据进行潮汐分析,得到井孔储水效应引起的相对振幅A和相位移η,进而分析A和η随时间变化的规律以及两者之间的关系.结果表明,井潮变化主要受井孔储水效应变化影响;在潮汐排水响应阶段,井潮主要受含水层导水系数T(或渗透系数K)影响,而受储水系数S影响较小.This paper analyzes the impact of wellbore storage effec~ on the well tide and that of transmissivity and storativity on tidal drainage response so as to discuss the origin for changes of well tide. Through tidal analysis of water level data monitored in the well Chuan06, and judgment of undrained response, we obtained amplitude response （A） and phase shift （r}） of tidal constituents Mz and 01 caused by the wellbore storage effect by removing the influence of frac- ture effect, and then comparatively analyzed Hsieh model and the actual relation between A and ~]. The results show that the changes in the well tide could be at- tributed to the changes in the wellbore storage effect, where as the changes in the hydraulic response were mainly attributed to the changes in transmissivity rather than that in storativity.
