摘要
鄂尔多斯盆地聚集了丰富的石油天然气资源, 靖边气田就是该盆地发现的特大
型气田。储集层类型为下古生界奥陶系古风化壳型, 其主力含气层为马家沟组第五段。吸收
了前人关于储层地质方面研究的大量成果, 从高分辨率层序地层学的角度, 研究奥陶系马家沟
组马五1－马五5 亚段风化壳储层, 并展开以准层序级别的层序地层格架分析研究, 在此基础上
探讨了高分辨率层序地层格架中风化壳的储层特征和天然气藏聚集模式。
Abstract
Abundan t gas and o il resources are accum ulated in Jingb ian gas fie ld, wh ich is one o f the oversized o il fie lds d iscove red in Ordos Basin. The reservo ir type is O rdov ic ian w eathe ring crust in the Lowe r Pa leozo ic, and the m a in gas layer is in the fifth m em be r ofM a jiagou Fo rm ation. This paper absorbed m ass of form er ach ievem ents on reservo ir geo logy, and expanded sequence ana lysis o f pa rasequence leve l from the first to fifth subm em be rweathering crust reservo ir from the po int of high reso lution sequence stra tigraphy. On th is basis, it d iscussed w eather ing crust reservoir fea tures and poo l form ation patte rn in h igh reso lution sequence stratigraphy.
