摘要(Abstract)：

针对宜川—旬邑地区勘探程度低,储层基础资料研究不足的特点,利用薄片鉴定、粒度分析、扫描电镜、镜质体反射率、阴极发光等多种测试分析手段,对宜川—旬邑地区的成岩作用及储层特征进行了深入地研究和探讨。确定了该区长八段目前处于晚成岩A期,建立了该区的成岩演化序列;阐明了各种成岩作用对该地区储层物性的影响。宜川—旬邑地区的勘探程度很低,本次研究填补了该区基础地质资料的不足,为在该地区开展更深入的研究奠定了基础。
Aiming at characteristics of low exploration degree and less basic data of reservoir of Yichuan-Xunyi area,this paper studies diagenesis and reservoir characteristics of this area through thin section analysis,grain size analysis,SEM,vitrinite reflectance and cathodeluminescence methods.It determines that Chang 8 Member in this area is in Stage A of late diagenesis,establishes diagenesis sequence of this area and illustrates effect of different diagenesis on reservoir property of this area.Yichuan-Xunyi area has a low exploration degree.This study compensates the shortage of basic geologic data and provides basis for further study.
