摘要

以胜坨油田二区东三段2⁴小层为研究对象, 综合考虑岩性、物性、电性和非均质

性及水淹等特征, 将河流相储集层流动单元分为4种类型, 分析了不同类型流动单元的特点,

建立了本区的流动单元模式, 探讨了流动单元对剩余油分布的控制作用。结果表明: Ⅰ型流动

单元储集性能最好, 但分布范围小, 剩余油少; Ⅱ、Ⅲ型流动单元为最佳储层和产层, 注水效果

好, 剩余油富集; Ⅳ型流动单元储集性能最差, 或是干层, 易形成剩余油, 但剩余油总量不大且

难开发, 经济价值不大。把流动单元研究与剩余油形成结合起来, 可以更好地预测剩余油分

布, 从而对油藏油水井部署及注采井网调整具有指导意义。

Abstract

Based on the layer 24 of the third m ember o f Dongy ing
Fo rm ation in the second b lo ck in Sheng tuo O ilfie ld, the flow
units of fluv ia l fac ies reservo irs we re studied and have been
d iv ided into four types in consideration o f lithology, phy sica l
property, e lectr ic property, he terogene ity, wa ter flood ing
features and other facto rs. The character istics o f flow un its
w ere analyzed, the correspond ing m ode l o f flow un its o f
fluv ia l fac ies reservo ir was set up. It d iscussed the flow un its
to con tro l the rema in ing o il d istribution. The resu lt indicates
tha t a lthough the flow unit 􀀁 has the best physica l character,
the distribution o f a rea and rem a in ing o il w ere few; that the
flow un its 􀀁 and 􀀁 are the best reservo irs and tha t the wa ter
injection response w as good and the rem a ining o il w as
enr iched. The phys ica l character of the flow unit 􀀁 is the
w orst and has no deve lopm ent va lue. The study of the
rem aining o il comb ined w ith flow units can g ive a better
d irecting in the rese rvo ir prediction, w hich m ay guide o il and
w ater w ell location and flood pattern mod ification.
