摘要

摘要: 鄂尔多斯盆地南部镇原—泾川地区（简称镇泾地区）上三叠统延长组长8油层组是典型的致密砂岩储层。通过铸体薄片分析、阴极发光薄片分析、荧光薄片分析、扫描电镜分析、X射线衍射分析、流体包裹体测试等多种分析测试方法对长8油层组储层开展了储层特征、成岩作用、油气充注时间与期次等研究，对孔隙度演化进行定量化分析，并基于成岩—成藏耦合关系的研究恢复了储层孔隙度的演化过程。研究表明，镇泾地区延长组长8油层组储层为长石岩屑砂岩、岩屑长石砂岩，成分成熟度与结构成熟度均较低，粒间充填钙质胶结物、硅质胶结物、自生黏土矿物等；储集空间以粒间溶孔、剩余原生粒间孔为主；储层处于中成岩阶段B期，发育了较强的压实作用、胶结作用，溶解作用相对较弱；储层致密化的主因为压实作用和胶结作用，分别造成减孔22.2%和14.6%，溶解作用增孔5.1%，交代作用增孔约0.6%。成藏早—中期储层未致密化，成藏晚期储层进入致密化阶段，总体储层致密化史—成藏史耦合关系为“先成藏，后致密”过程。

Abstract: The Chang 8 oil member of the Upper Triassic Yanchang Formation in Zhenjing area in the southern Ordos basin is typically a tight sandstone reservoir. Based on the analysis of cast thin sections, cathode-luminescence thin sections, fluorescence thin sections, SEM, XRD and fluid inclusions test etc., the reservoir characters, diagenesis and hydrocarbon emplacement and its phases are studied, the quantitative study on porosity evolution is conducted as well as porosity evolution is recovered with the coupling of diagenesis and hydrocarbon accumulation. These analyses indicate the sandstones are mostly feldspathic litharenites and lithic arkoses with low composition and textural maturity. The reservoir mainly develops carbonate cement, silica cement and authigenic clay minerals. It mainly develops intergranular dissolution pores and residual original intergranular pores. The reservoir is in the middle diagenetic stage B and develops intensive mechanical compaction and cementation but weak dissolution. Mechanical compaction and cementation play an important role in reducing reservoir porosity, resulting in decreases of porosity by 22.2% and 14.6%, respectively. Dissolution and replacement add 22.2% and 14.6% in porosity, respectively. During the early and middle oil emplacement phases, the reservoir is in good properties, while in late oil emplacement phase, the reservoir is in the densification stage. The coupling relationship between reservoir densification history and hydrocarbon emplacement is "densification after hydrocarbon accumulation".
