摘　　要：通过岩心观察和描述,结合普通薄片、铸体薄片、扫描电镜等资料,对营四段砾岩储层的岩石学特征进行了研究.结果表明:营四段砾岩储层砾石成分复杂,类型多样,三大岩类(岩浆岩、沉积岩、变质岩)成分的砾石均可见.通过砾岩成分、古剥蚀区及岩性特征研究,认为物源方向为北北西向.By subtle core observation, rock thin-section identification, cast thin-section picture statistic analyses, and scanning electron microscopic analyses, the lithologic characteristics and provenance of conglomerate in ying-4 segment of Xingcheng gas field have been studied. The results suggest that the component of conglomerate in ying-4 is complex and the type or rock is diverse, namely magnetic rock, metamorphic rock and sedimentary rock. The results indicate the provenance orientation is NNW by conglomerate component, denudation mountain, lithologic character.
