辽宁西部碳酸盐岩和碎屑岩的充水空间皆以次生空隙为主,其发育程度与分布受岩性层组和地质构造的综合控制。按综合控制条件,本区划分有富水结构、导水结构和阻水结构三类水文地质结构。在一个水文地质单元中,上述三类水文地质结构常组成一个具有特定排列、成生联系和水力联系的整体,本文称为含水系统。区内碳酸盐岩可划分出软硬相间可溶性岩组褶皱构造裂隙—岩溶含水系统、软硬相间可溶性岩组断裂—岩溶含水系统和层状弱面可溶性硬脆岩组断裂—岩溶含水系统三类,富水结构和导水结构的钻孔涌水量分别为500—5000m~3/d和10—150m~3/d。碎屑岩可划分出层状弱面软质岩组褶皱构造裂隙含水系统和层状弱面软塑岩组褶皱构造裂隙含水系统两类,富水结构和导水结构的钻孔涌水量分别为500—3000m~3/d和10—100m~3/d。
The water-filled spaces of carbonate rocks and clastic rocks in the western part of Liaoning Province are dominated by secondary voids. Their development and distribution are controlled by the lithologic group and the geological structure. According to the comprehensive control conditions, the district is divided into three types of hydrogeological structures of water-rich structure, water-conducting structure and water-blocking structure. In a hydrogeological unit, the above three types of hydrogeological structures often form a whole with a specific arrangement, genesis and hydraulic connection, which is referred to as an aquifer system. The carbonate rocks in the area can be divided into fractures of fractured-karst water systems of soft-hard interbedded soluble rocks, fracture-karst aquifers of soft-hard interbedded soluble rocks and fault-karst aquifer systems of layered weak facies soluble hard- The borehole water inflows of type, water-rich structure and water-conducting structure are 500-5000m 3 / d and 10-150m 3 / d, respectively. The clastic rocks can be divided into two types, that is, the fold-structure fractured aquifer system and the weakly-folded soft-plastic rock group in the layered weak soft facies group. The borehole water inflows in the water-rich structure and the aqueduct structure are 500-3000m ~ 3 / d and 10-100m ~ 3 / d.
