摘要 四川盆地海相三叠系(T1j-T2l)地下水按其构造开放程度、埋藏深度及水化学特征的不同,可明显划分出沉积变质卤水和渗入淋滤卤水两种基本类型,分属两个性质迥然不同的水动力系统,它们不存在规律性的演变现象,不是受统一的静水压力控制而构成,由盆地边缘向内部的区域水动力循环;而是两者各自显示了地静压力和静水压力由高压区向低压区驱动的水动力特征,并控制了盆地海相三叠系盐卤、气藏的分布、富集和保存。 With a view of structural openness, burial depth and hydrochemical features, the groundwater circulating in the marine Triassic sediments (T 1 j -T 2 l ) in Sichuan basin can be grouped into two major types: sedimentometamorphic and infiltration leaching. These two brines are keeping in hydrodynamic systems highly different from each other, rather other controlled by an unified regional hydrostatic system to show a regularly hydrodymamic shift from the basin's margins to center. Contrary, they are moving governed by separate land static and hydrostatic pressures from high pressure stand to low pressure one, a dynamic regime that efficiently decides the distribution, enrichment and preservation of oil and gas in the basin.
