摘　　要：对冀北坳陷中新元古界的地质工作早在上个世纪七、八十年代就已展开,但多侧重于岩石学、地层学和油气地质方面的研究,成岩作用和成岩相的研究相对薄弱。以辽宁省凌源县魏杖子剖面为例,利用岩矿测试资料,对研究区雾迷山组地层的成岩作用、成岩相进行研究,划分出7种基本成岩作用类型,并根据成岩组构、强度、序列及岩性特征,划分出5种成岩相类型。依据对各成岩相储集性能的分析,认为埋藏古岩溶-埋藏胶结和构造破裂-埋藏胶结成岩相具有相对重要的储集意义,并据此对雾迷山组有利储集层进行评价。The geological research on Neoproterozoic of Jibei Depression was carried out in the 1970s and 1980s,but most of them were focused on petrology,stratigraphy and petroleum geology research,the study of diagenesis and diagenetic facies were relatively weak.By taking the Weizhangzi Section of Lingyuan County in Liaoning Province as an example,the diagenesis and diagenetic facies of Wumishan Formation were studied,seven basic types of diagenesis were classified by using the various types of rock and mineral test data and five types of diagenetic facies were also classified in accordance with diagenetic fabric,intensity,sequence and lithologic features.Then based on the analysis of reservoir properties within the diagenetic facies,the favorable reservoirs of Wumishan Formation are evaluated,and it is considered the buried paleokarst-buried cementation and construction rupture-burial diagenetic cementation phase are of great significance of reservoir evaluation.
