吐哈盆地侏罗系地下水形成演化与层间氧化带的关系

Formation and Evolution of Jurassic Groundwater and its Relation to Interlayer Oxidation ZoneDevelopment in Toha. Basin

层间氧化带的形成、发育与地下水的形成演化是密切相关的。本文应用古水文地质的分析方法，对吐哈盆地侏罗系地下水的演化史进行了研究，并对侏罗系合水岩组划分出三个水文地质时期。定量地确定了地静压力系统和水位压力系统对沉积水的改造作用，计算了压挤水和渗入水的交替强度。指出了盆地南部移入水压系统区是侏罗系，层间氧化带发育的有利地区．

The formation, development of interlayer oxiodion zone has close relation to the formation and evolution of groundwater. It is studied that the evolution history of jurassic groundwater by use of palaeohydrogeological analysis method in Tuha basin. The jurassic aquiferous lithodeme can be divided into three hydrogeological Stage. It is quantitatively confirmed that the reformation process of terrastatic pressure system and water static pressure system on deposition water. Author also calculates the alternate intensity of squeeze water and penetration water. Penetration water pressurized system area in south basin is the beneficial part fordeveloping interlayer oxidation zone.
