综合动水位与流量值的等效静水位及其计算方法探索
|
摘要
中国地震地下流体观测网动水位观测中,一般同时观测水位与泄流量2个测项,产生2类动态,分别进行处理与分析。对含水层应力状态变化的信息,有时得到2种相反的结果。针对这种不合理的现状,以流体动力学理论为基础,探索了动水位观测井中水位与流量的关系,提出了等效静水位的概念,把水位与流量2个观测量合成为1个统一的物理量,建立了相应的计算方法,并用东水3井与聊古1井的观测资料进行了检验。
In our country,the water level and discharge flow rate are observed simultaneously when observing the dynamic water level in the seismic ground fluid observation network.Thus,two types of dynamic variations are obtained generally,and they are handled and analyzed separately.Two contrary results are obtained sometimes in the information of aquifer stress state change.Facing this irrational status,the relationship of water level to flux in dynamic water level observation well was explored based on the fluid dynamics theory.The equivalent static water level was put forward,synthesizing the two observation terms into one unified physical quantity.The calculation means to synthesize the water level and flux into one quantity was proposed and tested using the observation data of wells Dongshui-3 and Liaogu-1.
