| 摘 要： | 四川盆地三叠系地下水可划分出碎屑岩孔隙裂隙和碳酸盐岩岩溶裂隙两大储集类型。按此处构造开启程度和埋深条件等的不同,下中三叠统地下水有沉积变质水和渗入淋滤水两种基本成因类型,水动力特征各异。沉积变质水处于深埋封闭条件,受地静压力驱动控制;渗入淋滤水分布于背斜露头区和浅部地区,受静水压力驱动控制。并由此控制了盆地三叠系盐类的保存条件。

| Abstract: | The groundwater in the Triassic system of Sichuan Basin can be classified as two major storage categories:clastic rock aperture cranny and carbonate rock karst cranny.In terms of the extent of opening and depth of the conformations,the groundwater in the lower-middle Triassic series can be classified into sediment altered brine and penetration-eluviated brine,the formation mechanism and hydrodynamic characteristics of which are quite different.The former is deeply enclosed in its storages,and driven by the ground static pressure.The latter is located in anticlinal outcrop zones and shallow zones,and driven by static hydraulic pressure.Such groundwater characteristics determing the storage aspects of salts in the Triassic system of Sichuan Basin. |
