| 摘 要： | 以沉积相为基础，利用各类分析化验资料，对白豹油田长8油藏岩石学特征、储集特征和成岩作用开展深入研究。结果表明，研究区储层岩石成分成熟度偏低，结构成熟度中等，储集空间以粒间孔、长石溶孔为主，表现为细孔、微孔和细喉、微喉特征。依据本文提出的评价方法对研究区4种主要的成岩作用进行定量评价，表明储层成岩作用以中等-强压实、中等-强胶结、中等-强交代、中等溶蚀为主。综合以上研究,将白豹油田长8油藏划分为强溶蚀弱胶结混合孔隙成岩储集相、中等压实中等溶蚀复合孔隙成岩储集相、强压实中等胶结残余孔隙成岩储集相、强压实强胶结微孔隙成岩储集相4种类型,其中,强溶蚀弱胶结混合孔隙成岩储集相油气储渗能力最强，强压实强胶结微孔隙成岩储集相油气储渗能力最差。

| Abstract: | Based on sedimentary facies research, using all kinds of analysis data, the petrology, reservoir space and diagenesis of Chang 8 reservoir in Baibao oilfield have been studied in detail. The results show that compositional maturity is low and structural maturity is moderate, intergranular pore and feldspar dissolution pore are the main pore types, the pore throat is thin or tiny. According to authors’ method, four kinds of main diagenesis are quantitatively evaluated. The diagenesis is medium-intense compaction, medium-intense cementation, medium-intense metasomatism, medium erosion in the area. Finally, according to the research, four types of diagenetic reservoir facies are identified including mixed pore diagenetic reservoir facies with strong solution and weak cementation, compositional pore diagenetic reservoir facies with moderate compaction and moderate solution, residual pore diagenetic reservoir facies with strong compaction and moderate cementation, micropore diagenetic reservoir facies with strong compaction and strong cementation. The first diagenetic reservoir facies is the best for oil accumulation and seepage, the fourth diagenetic reservoir facies is resistant to oil accumulation and seepage. |
