中文摘要: 朱家沟组集中分布在鲁中南坳陷盆地边缘地带,为一套陆源碎屑沉积的灰质砾岩。以汶口盆地、新汶盆地朱家沟组为研究对象,通过1:50000水文地质调查、水文地质钻探、地球物理勘探、抽水试验、水质分析等技术方法,分析其水文地质特征。研究结果表明:朱家沟组裂隙岩溶形态以溶蚀裂隙、溶孔、溶洞为主,主要发育在150 m以浅;富水性受断裂控制明显,裂隙岩溶发育段单井涌水量可超过300 m3/d,具有显著实际供水意义;朱家沟组富水模式为断裂型灰质砾岩裂隙岩溶蓄水构造模式,以断裂构造为主控因素,该模式在鲁中南地区具有普遍性和适用性,对于寻找新的供水目标含水层及找水定井工作具有指导意义。
Abstract:The Zhujiagou formation, a set of calcareous conglomerates of terrigenous clastic deposition, is mainly distributed along the edge of the depression basins in south-central Shandong. Taking the Zhujiagou formation in the Wenkou basin and the Xinwen basin as the study area, the hydrogeological characteristics are analyzed through 1:50000 hydrogeological survey, hydrogeological drilling, geophysical exploration, pumping test, water quality analysis and other technical methods. The results show that the karst morphology of the Zhujiagou formation is dominated by corrosion fissure, karst hole and karst cave, which are mainly developed in the shallow layer of 150 m. The water yield property is obviously controlled by the fracture, and the water inflow of a single well in the fracture karst development area can be more than 300 m3/d, indicating practical water supply significance. The water yield pattern of the Zhujiagou formation features fracture-karst water storage structure of fractured calcareous conglomerate and fracture structure is the main controlling factor. This pattern has universality and applicability in south-central Shandong Province, which is of guiding significance for new water supply aquifers exploration and site selection and layout for wells.
