摘要

运用非均质综合指数, 以胜坨油田坨28断块沙二段8、9砂层组为例, 对河口坝

砂体储层的层间、层内、平面非均质性进行了定量表征, 并分析了非均质性与剩余油分布之间

的关系。认为河口坝储层层间非均质性弱, 而层内、平面非均质性以中等— 弱为主, 非均质综

合指数与含油饱和度有良好的对应关系, 剩余油主要分布在非均质性中等的区域内。

Abstract

By using the he terogeneous synthetic index and tak ing
the 8th and 9th groups of E s2 fo rm ation of Tuo 28 fau lt b lock
in Shengtuo o ilfie ld as an examp le, the inter layer, interna l
and plane heterogene ity of debouch bar reserveoirs have been
characterized. The relationship be tw een he terogene ity and
rem aining o il has been analysed. The inte rlaye r heterog ene ity
o f debouch ba r reserveo ir is weak, and the inte rnal and p lane
heterogene ity is m iddle to w eak. The he terogeneous synthetic
index corresponds w e ll w ith o il - bearing satura tion. The
rem aining o il is m ainly d istr ibu ted in m idd le heterog ene ity
reserveo ir.
