| 摘 要： | 徐州大北望地区寒武系为华北地台陆表海环境的典型沉积建造,寒武系碳酸盐岩生油潜力及储集层发育情况都有待于研究,对典型剖面进行分析研究具有重要油气地质意义。通过分析本区寒武系岩石学及陆表海沉积环境特征,恢复了区域海平面变化周期及古地理环境。通过综合野外露头与室内分析,研究区寒武系主要发育的岩石类型为碳酸盐岩,其中鲕粒灰岩厚度较大。结合区域构造及沉积背景分析,本区寒武系陆表海环境中发育沉积相类型主要为:潮坪相、浅滩相、局限台地、开阔台地、台地浅滩。本区沉积演化为:早寒武世主要以潮坪沉积为主,中寒武世发生了寒武系最大一次海侵,台地鲕粒滩相较发育,晚寒武世水深逐渐变浅,出现局限海,潮坪环境。分析得出台地浅滩相中发育的鲕粒灰岩及云坪沉积的白云岩为较有利油气储集层。

| Abstract: | Cambrian deposition in Dabeiwang,Xuzhou is a typical type of epicontinental sedimentary formation developed on North China platform.The oil-generating potential of Cambrian limestone in the study area and the development situation of reservoir are require further study,and the analysis of representative sections in Dabeiwang are of profound petroleum geological significance.Based on the analysis of the Cambrian petrological features and epicontinental sedimentary characteristics,regional sea-level changes a... |
