摘要：

本文在岩石学研究的基础上,应用阴极发光、氧碳稳定同位素、微量元素、混合染色的资料,详细地研究了鄂中上石炭统碳酸盐岩的成岩作用、成岩序列和孔隙演化,认为:填积作用、胶结作用、溶蚀作用、白云石化作用、压实、压溶作用,是控制鄂中上石炭统碳酸盐岩储集性能的主要因素,其中,白云石化作用、压溶作用、埋藏溶蚀作用是形成聚集期孔隙(油气运移、聚集时岩石的孔隙)的最为重要的因素。

关键词: 鄂中, 成岩作用, 孔隙演化, 聚集期孔隙

Abstract:

Based on the study of petrology,using the data of cathodoluminescents,stable iso-topes of oxygen and carbon,trace elements and composite colouring,the diagenesis,diage-netic sequences and pore evolution of Upper Carboniferous carbonates in Central Hubei were studied in detail.The study shows that filling,cementation,solution,dolomitization,compaction and pressure-solution were the principal factors in controlling the reservoir properties of the Upper Carboniferous in Central Hubei,the most important of which were the dolomitization,solution in deep burial environment and pressure-solution in forming the pores of accumulation stage.
