摘要
采用深井钻探、PACKER试井、水化学与同位素分析、水流数值模拟等技术方法和手段,以主干水文地质剖面为研究对象,对鄂尔多斯盆地西部巨厚的白垩系含水层中的地下水流系统结构进行了研究,结果表明:北部白垩系各含水岩组构成统一含水体,含水层中地下水流连续,在地形控制下形成了多个规模不等、循环深度不一的多层结构地下水流系统,具有穿层型多层结构水流模式;南部白垩系各含水岩组相互独立,各含水岩组之间地下水流不连续,地下水顺层运动,具有顺层型多层结构水流模式。
By the techniques of deep drilling exploration, PACKER drilling test, analysis of hydrochemistry and isotope, flow numerical simulation, and so on and taking the main hydrological geological section as the research object, the thick Cretaceous aquifer groundwater flow system structure of the west of Ordos basin were studied. The results show that on the north under the control of the terrain, many groundwater flow systems of muhilayer structure with different sizes and cycle depth are developed with the pattern of cross-formational gravity-flow ; on the south of these cretaceous aquifers are independent with each other. The groundwater in these aquifers is discontinuous. Groundwater flows within layered aquifers. These groundwater systems are developed with the pattern of multilayer structure bedding flows.
