鲁中南新汶盆地地下水蓄水模式分析

Analysis on Groundwater Storage Model in Xinwen Basin in Central and Southern Shandong Province

摘要:

基于新汶盆地开展的1∶5万区域水文地质调查工作，运用水文地质测绘、地球物理勘探、水文地质钻探等工作手段，查明区内主要含水岩组及其水文地质特征，总结地下水蓄水构造模式。研究结果表明：盆地内主要富水岩组为古近纪朱家沟组，奥陶纪马家沟群，寒武纪三山子组、张夏组、朱砂洞组地层；地下水蓄水模式分为岩层阻水型蓄水构造、断裂型蓄水构造和层间岩溶蓄水构造三类，其中断裂型蓄水构造根据含水层岩性不同又可划分为断裂型灰质砾岩裂隙岩溶蓄水构造、断裂破碎带型裂隙蓄水构造、断裂破碎带型裂隙岩溶蓄水构造。

Abstract:

Based on regional hydrogeological survey with the scale of 1∶50000 in Xinwen basin, by means of hydrogeological survey, geophysical exploration and hydrogeological drilling, main water bearing rock formation and its hydrogeological characteristics in the area have been identified, and the structure model of groundwater storage has been summarized. It is showed that main water rich formations are Paleogene Zhujiagou formation, Ordovician Majiagou group, Cambrian Sanshanzi formation, Zhangxia formation and Zhushadong formation. The groundwater storage model can be divided into three types: strata water retaining structure, fault water retaining structure and interlayer karst water retaining structure. According to the lithology of aquifer, the fracture type water storage structure can be divided into fracture type limestone conglomerate fracture karst water storage structure, fracture fracture zone fracture karst water storage structure and fracture fracture zone fracture karst water storage structure.
