隔夹层是流体在储层中流动的重要影响因素之一,也是储层精细表征的重要内容。随着开发进入高含水期,油层内部发育的隔夹层对开发效果及剩余油分布有着很大的影响。红南2块油藏为巨厚砂岩边底水背斜构造油藏,发育有稳定的隔夹层,该文以红南2块白垩系油藏为研究对象,通过机理模拟、精细刻画等工作研究隔夹层在油藏的发育情况,为剩余油综合研究和下步挖掘提供依据。
Intercalation is one of the important influencing factors of fluid flow in reservoirs, and also an important content of fine reservoir characterization. As development enters the high water cut period, the interbeds developed within the reservoir have a significant impact on development effectiveness and remaining oil distribution. The two reservoirs in Hongnan are characterized by oil-water anticline anticlinal reservoirs with thick sandstone and stable interbedded layers. This paper deals with two Cretaceous reservoirs in Hongnan, through mechanism simulations and fine depiction Interlayer in the reservoir development, for the remaining oil comprehensive study and the next step to provide the basis for mining.
