摘要
根据大港枣园油田枣35块火成岩的岩性、产状及其分布规律,建立了火成岩岩相模式,将火成岩岩相划分为2个亚相(爆发相和溢流相)和4个微相(凝灰岩、火山角砾岩、气孔玄武岩、致密玄武岩微相),分析了其形成机理和微相的剖面、平面分布特征。初步尝试利用地震属性研究火成岩岩相,探讨了火成岩微相对储集空间类型、裂缝发育程度的控制作用。
Based on lithology characteristics and distribution of igneous rocks in the Zao 35 Block of Dagang Oilfield, the lithofacies mode of igneous rocks is established. Based on themode, the igneous rocks are divided into two lithofacies (outburst and overflow facies) and four microfacies (tuff, volcanic breccia, vesicular basalt, and dense basalt microfacies). The profile and plane distribution characteristics of microfacies are described. The attempt is made on calibrating igneous lithofacies with seismic attribute. The domination of igneous microfacies on the types of reservoir space and degrees of fracture growth are also studied.
