基于低渗透油藏高含水期的剩余油分布规律、挖潜单元以及相对应的挖潜技术对策。低渗透油藏砂体是地质上具有成因联系、开发上相对独立的砂体单元,既是地质上的成困单元,也是与剩余油分布有关的渗流单元,既反映了砂体的沉积成圈,也决定了剩余油分布特征和注水开发特征。
Based on remaining oil distribution regularity, potential units in tapping low permeability reservoirs during high water cut stage and related potential tapping technical measures. Low permeability reservoir sand bodies are geologically related and relatively independent units of sand bodies. They are not only geological units of trapped units but also seepage units related to remaining oil distribution, which not only reflect the sedimentation of sand bodies into a circle, Also determines the remaining oil distribution characteristics and water injection development characteristics.
