摘要：

九佛堂组砂岩储层为水下扇沉积,研究区内可见中扇和外扇。水下扇经历了发育、成熟和衰亡三个阶段,分别对应于Ⅲ、Ⅱ、Ⅰ三个砂组,相当于外扇、中扇外缘叶状体和中扇内缘沟道相。储层孔隙度变化不大,但渗透率变化剧烈,反映砂体强烈的非均质性。根据毛管压力特征,可分出中孔中渗型、中孔低渗型和低孔特低渗型三类储层。

Abstract:

Sandstone reservoirs of the Jiufutang Formation are submarine fan deposits which could be divided into middle and outer fans. The submArine fans underwent three evolution stages such as development, maturation and decline stages that correspond to Ⅲ, Ⅱ and Ⅰ sand formations, and these sand formations, in turn, equal to outer fan, the outer marginal blade and the inner marginal channel of the mid-fan. The porosity of the reservoir did not change much but its permeability varied intensely. This reveals serious heterogeneity of the sandbodies.According to the capillary pressure, the reservoirs could be divided into mid pore-mid permeability, mid pore-low permeability and mid pore-very low permeability types.
