安塞油田长10储层岩石学特征
|
摘要
通过对区域地质背景及岩石学特征的分析,研究了安塞油田长10储层的岩石学特征及其成岩作用。研究手段有铸体薄片观察、扫描电镜、X-衍射及压汞。得出结论包括:安塞油田长10储层岩石的主要类型以长石砂岩和石英长石砂岩为主,砂岩的填隙物的成分以杂基和胶结物为主,含量不高,安塞油田长10储层的岩石结构以细砂岩为主,胶结类型也全部为孔隙式胶结,岩石颗粒的接触方式大部分为线接触,部分为点线接触,因此可以确定它的结构成熟度较高。
Petrological characteristics and diagenesis of Ansai oilfield Chang10 oil-bearing formation were studied through the regional geological background analysis. Research tools included cast thin section observation, scanning electron microscope, X-ray diffraction and the capillary pressure.The results showed that, main rock types Ansai oilfield Chang10 oil-bearing formation are feldspathic sandstone and feldspathic quartz sandstone; interstitial materials in the sandstone are miscellaneous base and cement, their content is not high. The rock structure of Ansai oilfield Chang10 oil-bearing formation is fine sandstone, cementation type is also pore cementation, contact way of rock particles is the line contact,the part is the point contact, so the maturity of its structure is higher.
