W由于区块进入中后期开发阶段,含水上升速度快,采出程度高,调整挖潜难度大。为了控水,为了提高水驱调整的针对性,本文以“A区块精细油藏描述”为基础,分析控制井点油水分布的主导单元,进而确定主导单元的优势水驱方向,分清主、次、弱水驱优势,指导下一步水驱综合调整。 As the block enters the middle and late stages of development, the water-bearing moisture has a fast rise rate and a high degree of recovery, making it difficult to adjust and tap the potential. In order to control the water, in order to improve the pertinence of waterflooding adjustment, based on the description of fine reservoir in Block A, this paper analyzes the dominant units that control the distribution of oil and water in well points and then determines the dominant waterflooding direction of dominant units, The main, secondary, weak flooding advantage, guiding the next step comprehensive adjustment of water flooding.
