摘    要:利用铸体薄片、阴极发光、扫描电镜、黏土矿物X衍射分析、有机质成熟度分析等多种分析测试方法,研究了新立低渗透油田泉三、四段储层岩石学特征、储集特征、储集空间类型、喉道类型,分析了该区泉三、四段的成岩作用及其对储集物性的影响,以此为基础探讨了成岩序列和成岩阶段的划分,进而研究了目的层段储集空间的演化.最后从成岩作用角度分析了本区低渗透储层的成因:埋藏成岩过程中各种自生矿物的充填和胶结作用,堵塞了孔喉,因而使本区储层的渗透率降低,加之强烈的压实作用,最终形成了本区低渗透储层.

关 键 词:新立油田  泉三、四段  成岩作用  储集特征  孔隙演化

Abstract:The lithology, reservoir features, and the types of pore and throat of the reservoir are studied based on the analysis data of cast thin-sections, cathodoluninescene, SEM, X-ray diffraction of clay minerals, organic matter maturity etc. The effects of diagenesis on the petrophysical properties of the reservoir are analyzed. The space evolution of the third and the forth of Quantou Formation in Xinli low permeability oil field. Based on these, the division of diagenesis sequences and diagenesis stages is discussed, and the pore evolution of the reservoir is studied. Finally, the forming mechanism of the low permeability reservoir is analyzed from the point of diagenesis. Since packing and cementation of all kinds of autigenic minerals plug the pore throat in the diagenesis process, together with the strong mechanical compaction, the permeability of the reservoir is reduced and finally the low permeability reservoir is formed.
Keywords:Xinli Oilfield  Quantou Formation  diagenesis  reservoir feature  pore evolution
