摘要:: 从地下流体观测井-含水层系统对降水的响应特征、对气压和潮汐的响应特征、含水层水文参数的计算对比以及水-岩作用平衡状态4个方面,研究了云南红河地区5口地下流体观测井-含水层系统特征。结果表明:不同井-含水层系统对外界扰动(影响因素)的响应能力有所差别,其中高大井对地壳应变响应的灵敏性最强,其次是开远井、建水井,石屏井和蒙自井最弱,响应能力主要与井-含水层水力参数、承压性和水-岩平衡状态等因素有关。

Abstract:: In this paper we study the characteristics of the well-aquifer system of 5 observation wells for underground fluid—Gaoda Well,Kaiyuan Well,Jianshui Well,Shiping Well and Mengzi Well in Honghe region,Yunnan Province.We firstly calcultate hydrological parameters of the aquifers,then we analyze the equilibrium state of water-rock interaction,and the response of the well-aquifer system to precipitation,atmosphere pressure,and Earth tide.The results show that the responsiveness of different well-aquifer systems of the 5 wells to external disturbances(influencing factors)is different; Gaoda Well is the most sensitive to Crustal strain,then followed by Kaiyuan Well,Jianshui Well,Shiping Well,and Mengzi well.This is mainly because of the confining capacity,the hydraulic parameters of the well-aquifer system,and the water-rock equilibrium state,etc..
