摘　　要：在对山东鲁西地区野外露头及济阳坳陷钻井岩心进行野外观察基础上,通过相似区露头调查、地层划分对比、薄片鉴定、试井测井资料分析、岩石力学测试、有限元分析等方法对鲁西及济阳坳陷地区太古宇裂缝进行了定性、定量分析,并对其发育规律进行了探讨,重点讨论了裂缝发育的控制因素:岩性、构造应力及上覆岩层等。得到的裂缝描述参数及发育规律对揭示济阳坳陷地区太古宇裂缝储集空间的分布具有重要的指导意义。The fracture characteristics of Archean-Strata are studied based on the outcrops, drilling, well test, and log data in the areas of Jiyang Depression and Western Shandong. Then the qualitative and quantitative analyses on the characteristics are conducted through field work in the similar outcrop area, stratigraphic division and core comparison, thin section authentication, rock mechanics test, and finite element method. Finally, the main factors that control the fracture development in the study areas, such as lithology, tectonic stress, and overlying strata, are discussed. The fracture description parameters are obtained and they play a directive role for revealing the distribution of reservoir space of Archean-Strata in Jiyang depression.
