| 摘 要： | 通过野外剖面、岩心观察、薄片鉴定,结合扫描电镜与能谱分析等测试手段,在充分认识富县地区长6、长8油层组储层特征、成岩作用基础上,研究长6、长8油层组成岩相类型.主要成岩相包括有泥岩强烈压实相、砂岩压实(压溶)相、砂岩剩余原生粒间孔隙-次生溶蚀孔隙相、砂岩次生溶蚀孔隙相和微裂缝相等5种类型.结合沉积环境及沉积相平面展布特征,阐述了成岩相平面分布,结合储层发育特征主控因素深入研究成岩相特征主控因素,表明沉积环境为成岩相特征提供了物质基础,沉积物在后期成岩演化过程中受成岩作用控制,即成岩相为沉积物在成岩演化后的具体体现. |

| Abstract: | In this paper,the authors study in detail the reservoir characteristics and diagenetic types of Chang 6 and Chang8 formations from geologic section observation,core observation,thin section identification,by microscope,scanning electron microscopy(SEM) and photoelectron spectroscopy.The main diagenetic types include compaction,cementation,erosion and so on.The authors further study the types and characteristics of the diagenetic facies.There are five types which include mudstone compaction facies,sandstone compaction-pressolution facies,sandstone residual protozoal intergranular-secondary dissolution facies,sandstone secondary dissolution facies,and micro-fractures facies.Combined with sedimentary environment and sedimentary facies distribution then elaborated into llithofacies characteristics distribution,combined with the influencing factors of reservoir characteristics of research llithofacies characteristics of the influencing factors,indicate the material foundation for diagenetic phase of sedimentary environments the sediment in the diagenetic process,namely the specific embodiment of llithofacies,which from sediments to rock with various diagenetic characteristics. |
