摘要:
为深化七里村油田油气地质特征认识，针对延长组长6油层浊沸石发育特征、胶结机制及其对物性的影响，采用孔渗分析、薄片鉴定及扫描电镜等分析手段，对长6油层砂岩成岩作用开展了系统研究。结果表明，长6油层发育同生成岩期、早成岩A期和晚成岩A期3期浊沸石。同生成岩期，浊沸石胶结主要受沉积环境和物源影响，长6油层砂岩火成岩碎屑中玻璃质矿物及变质岩屑的水化作用，为早期浊沸石的生成提供了丰富的物质；早成岩A期，斜长石的钠长石化作用为浊沸石胶结提供了重要物质基础；晚成岩A期，胶结与浊沸石过饱和析出有关，所需的Ca2+及SiO2等来源于早期浊沸石、长石及岩屑颗粒溶蚀等。浊沸石胶结与长6油层物性关系密切，早期浊沸石胶结阻止了碎屑颗粒进一步压实，亦为后期溶蚀形成大量次生孔隙提供条件；晚成岩A期的浊沸石溶蚀，扩大了储集层孔隙空间，同时改善了储集层孔喉结构和连通性。
Abstract:
To deepen the understandings about geological features of oil and gas in Qilicun oilfield, regarding laumontite development, cementation mechanism and their influences on reservoir physical properties in Chang 6 member of Yanchang formation and based on the porosity and permeability analysis, thin section identification and SEM analysis, the paper performs a systematic study on the diagenesis of sandstones in Chang 6 member. The results show that 3 stages of laumontite are developed in the Chang 6 member, namely syndiagenetic, early diagenetic stage A and late diagenetic stage A. In the syndiagenetic stage, laumontite cementation was mainly influenced by sedimentary environment and provenance, and the hydrations of metamorphic debris and vitric minerals in igneous rock debris in the sandstone of Chang 6 member provided enough materials for the generation of the early laumontite. In the early diagenetic stage A, albitization of anorthose provided the important material basis for the cementation of laumontite. In the late diagenetic stage A, the cementation was related to the oversaturated precipitation of laumontite, and the Ca2+ and SiO2 came from the dissolutions of early laumontite, feldspar and debris. The laumontite cementation was closely related to the reservoir physical properties of Chang 6 member. The early laumontite cementation prevented debris from further compaction and also provided favorable conditions for the formation of secondary pores during late dissolutions. The dissolution of the laumontite expanded the pore spaces of the reservoir and improved the pore throat structure and connectivity during the late diagenetic stage A
