升382井区砂体规模较小,300m井网对砂体控制程度较低,注采不完善,单向受效储量所占比例较大。受裂缝方向和储层非均质性的影响,局部区域油水井含水上升过快,增储上产、稳油控水难度越来越大。因此,加强剩余油分布规律研究、搞清其分布特征、采取有效对策是提高原油最终采收率的必由之路。本文主要运用流线模拟和数值模拟研究升382井区剩油分布规律,并且采用加密调整、注采关系调整、各种措施方法以达到提高采收率的目的。
The sand body of Well 382 is smaller in scale and the control well of 300m well pattern has a lower degree of control over the sand body. The injection and production are imperfect and the proportion of unidirectional effective reserves accounts for a large proportion. Affected by the direction of fractures and reservoir heterogeneity, the water-cut of oil and water wells in some areas increases too fast, and increases production and reserves, making it more and more difficult for water to be stabilized. Therefore, strengthening the research on the distribution law of remaining oil, clarifying the distribution characteristics and adopting effective measures are the necessary ways to increase the ultimate recovery rate of crude oil. In this paper, we mainly use the streamline simulation and numerical simulation to study the remaining oil distribution pattern in Well 382, and adopt encryption adjustment, relationship adjustment between injection and production, and various measures to achieve the purpose of enhancing oil recovery.
