| 摘 要： | S油田目前处于高含水开发后期,针对其反韵律砂岩储层及原油高粘高密度的特点,运用数值模拟对剩余油的影响因素如纵向渗透率级差、原油粘度、采液速度,井距等进行了研究,分析得出原油粘度、纵向渗透率级差主要影响剩余油分布的富集程度及见水早晚,隔层的存在减弱了重力及毛管力作用,不利于下部油层动用,并回归出了各因素对剩余油分布影响的定量关系式,为有效地实现剩余油分布的定量描述提供了基础。

| Abstract: | Soilfield is in the late high water cut development currently,according to its inverted layered sandstone reservoir,high-viscosity and density oil characteristics,numerical simulation is used to study the influence factors of residual oil such as vertical permeability heterogeneity,oil viscosity,fluid velocity and well spacing.We conclude that crude oil viscosity and vertical permeability heterogeneity play a decisive role in the enrichment of remaining oil distribution and water breakthrough time,and the i... |
