Abstract: Weathering crust in the middle-upper Proterozoic and lower Paleozoic carbonate rocks is widespread in North China By the example of lower Paleozoic erathem in the west Shandong uplift,a brief discussion is given to the reservoir characteristics of weathering crust in carbonate rocks: the classification of reservoir pore space and the rules regarding its development and distribution.According to field observation and laboratory examination,the author has named ten types of reservoir pore space and their distinctive features.On the basis of informations obtained from drill holes for hydrogeologic survey in the Zou County,the character of development,the limit of depth and the controlling effect of the cavern-fracture system in the lower Paleozoic weathering crust is analysed.The results obtained may have some significance to the further study of the reservoir conditions of the carbonate rock weathering crust in North China.

摘要： 中、上元古界和下古生界碳酸盐岩风化壳遍布华北。本文以鲁西隆起下古生界为例,研究了它们的储集空间类型及其发育与分布特征,根据野外观察及镜下鉴定,发现了十类储集空间;然后,综合邹县地区大量水文地质钻孔的静态和动态资料,分析了下古生界风化壳中孔洞-缝体系的发育特点、深度范围及其控制因素。
