摘要：

针对砂质辫状河，采用水驱油物理模拟的手段，旨在总结心滩内部泥质夹层（落淤层与沟道）控制的剩余油分布模式。模拟结果显示，夹层延伸长度、注采井与夹层的匹配关系、射孔位置等因素均对剩余油分布有控制作用。夹层水平延伸长度越大，夹层顶部和底部剩余油富集范围越大；如果两组模拟试验注采井射孔层位相同，采油井钻遇夹层的情况下剩余油更为富集；在注水井全井段射孔的条件下，与采油井全井段射孔相比，采油井上部射孔夹层附近剩余油富集范围较大，采出程度较小。

Abstract:

This paper aimed to summarize remaining oil distribution patterns controlled by muddy interlayers within braided bar of sandy braided river reservoir, using the method of waterflooding physical simulation. Our results show that remaining oil distribution is controlled by three factors, i.e.,  extensional length of interlayer, matching relationship between injection & production wells and interlayer, and perforation interval location. The longer the horizontal extension length of interlayer, the more enrichment space of remaining oil. If the perforation condition of injection and production wells is the same, when the production well was drilled into the interlayer, remaining oil will be more enriched. If the entire interval is perforated in the injection well, compared to the entire perforation interval of production well, enrichment space of remaining oil is bigger in the upper perforation interval of production well, and the degree of reserve recovery is smaller.
