摘要
本文通过孔洞充填物形成期次，充填矿物类型及地球化学特征的研究，指出有效孔洞的不均一分布控制了陕甘宁盆地中部奥陶系顶部白云岩的储集性和井孔产气能力。
Vug is an important oil-gas gathering space in some oil / gas reservoir, during the long period of geological history, vug system experiences complicate evolution process, fully developed cavern is reformed by filling substance of later stage. By studying phase of vug filling substance type of filling substance and their geochemical characteristics, this paper emphase on the uneven distribution of effective vug, which controlsreservoir characteristics and gas productivity of dolostone on the top of Orclovician system in this area.
