摘要:

高含水老油田经过长期注水开发,油水关系分布进一步复杂化,随着油气藏开发的不断深入,剩余油分布越
来越分散,相关地质研究越来越细。剩余油分布不但受储层物性、砂体分布、构造的影响,同时也受注采井网与砂体配
置关系的影响,因此注采井网与砂体如何进行配置的研究成为老油田进一步提高采收率的关键因素之一。以冀东高
深南某断块为例,建立了扇三角洲前缘砂体地质模型,在搞清扇三角洲前缘水下分流河道的基础上,应用数值模拟研
究了水下分流河道砂体与储层物源方向对注采井网、井位的影响,提出了扇三角洲前缘水下分流河道储层类型的注采
井网部署优化方案。

Abstract:

After a long period of water flooding development,The oil and water distribution of high water cut oil field is
becoming complicated. The remaining oil is more scattered and the related geological studies are becoming more specific. The
remaining oil distribution is not only influenced by reservoir physical property ,sand body distribution,structure effect,and
by injection- production well patterns and sand body relation. So,the study of injection-production well patterns and of how
sand body carries on the configuration is the one of the key factors to further enhance oil recovery of the high water cut oil
fields. Taking a fault block in eastern Jidong Gaoshennan as an example,We established the geological model of the fan delta
frontal sand body. After figuring out fan delta subsea distributary channel clearly,the paper studied how distributary channel
and reservoir physical source direction influenced the injection-production well patterns and the well position by Eclipce. So,
the paper put forward injection-production well patterns deployment optimization scheme of fan delta front subsea distributary
channel reservoir.

Key words: fan delta, subsea distributary channel, injection-production well network optimization, remaining oil, reservoir
