辽宁西部中生代盆地碎屑岩类的富水规律

以四官营子盆地、喀左盆地、大平房烧锅杖子盆地和北票哈尔脑盆地为例对碎屑岩类地下水的富水规律进行分析研究,在明确辽宁西部中生代盆地水文地质条件的基础上,将中生代盆地碎屑岩类地下水分为风化裂隙水、层间裂隙孔隙水和构造裂隙孔隙水3种。分析结果表明:构造裂隙孔隙富水性最好;从碎屑岩区内的成井分布来看,70%以上的井成于褶皱发育地段,且水量较丰富。

Groundwater enrichment rule in fragmental rocks of Mesozoic basins in western Liaoning Province

The Siguanyingzi Basin, the Kazuo Basin, the Dapingfang-Shaoguozhangzi Basin and the Beipiao-Haemao Basin were used as investigation areas to study the groundwater enrichment rules in fragmental rocks. Based on the hydrogeological conditions of the Mesozoic basins in westem Liaoning Province, the groundwater in fragmental rock is divided into efflorescent fracture water, interstratified fracture pore water and structural fracture pore water, of which the structural fracture pore water accounts for the most groundwater. According to the distribution of wells in the fragmental rock area, more than 70% of the wells are located in the fold belt and are rich in water. Study on the enrichment law of groundwater in all kinds of fragmental rock will not only offer a guide for seeking groundwater, but also provide scientific evidence for groundwater exploration in the area.
