基于井潮、气压效应的苏皖地区突出水位异常分析
|
摘要
基于流体及岩石力学理论,利用气压和潮汐效应,研究了苏皖地区苏02井、苏03井、苏06井、苏18井和定远04井含水层介质在不排水状态下孔隙度和渗透系数的变化情况.结合井-含水层系统在受力和水均衡两种状态下的微动态变化模型,分析了各井水位自2014年下半年以来相继出现同步上升现象的水动力学成因机制.结果表明:1 5口井的气压系数与M2波潮汐因子之间存在明显的线性关系,即气压系数越大,潮汐因子也越大;2各井的孔隙度和渗透系数出现一组同步增大现象,主要与补给量大于泄流量、补给增强有关.
Based on the theories of fluid and rock mechanics,we have studied the variation of porosity and permeability coefficients of the wells Su02,Su03,Su06,Su18 and Dingyuan04with barometric pressure and tidal effect in aquifer medium under undrained condition.Using the micro dynamic models of wellaquifer system under the conditions of force and water balance,we also analyzed the mechanism of simultaneous rise in water level since the second half of 2014.The results show that:1 There is a linear relationship between the barometric coefficient and the tidal factor of M2 wave for the five wells,that is,the lager the barometric coefficient,the larger the tide factor;2 A set of synchronous enlargement phenomenon occurred in porosity and permeability coefficient of each well,which is mainly because that the recharge is greater than the discharge.
