| 摘 要： | 通过对安塞油田取芯井的岩心观察和大量样品的铸体薄片、扫描电镜分析,对本区长6油层组储层取得以下认识:(1)安塞油田长6油层组储层砂岩以细粒长石砂岩和岩屑质长石砂岩为主,碎屑以长石为主,具有成分成熟度较低,结构成熟度较高的特点;(2)本区与孔隙的形成和演化关系密切的的成岩作用有压实作用、胶结充填作用和溶解作用三种类型;(3)砂岩中发育有粒间溶孔、粒内溶孔、微裂缝、晶间孔等孔隙类型,前两种溶孔构成了本区的有效孔隙。(4)储层物性主要受沉积微相及成岩作用的影响。沉积作用决定了砂岩中碎屑的矿物成分和结构,而成岩作用又可使其矿物成分和孔隙结构发生重大变化。 |

| Abstract: | Through the core observation of core wells and a large number of samples thin sections,scanning electron microscopy analysis of the Chang 6 reservoir,oil Ansai oilfield, the result shows that:(1)The main sandstone of the reservoir sandstone of Chang 6 oil,Ansai Oilfield is fine-grained arkose and lithic feldspathic sandstone,detrital feldspar-based, characteristics of low compositional maturity,high structure maturity.(2)The diagenesis which closely related to formation and evolution of pore,in this field i... |
