X井区乙块剩余油分布数值模拟研究

The study on numerical simulation of residual oil distribution of X wellblock B block

X井区乙块油藏经过多年的注水开发,含水率逐年上升,开发效果日益变差。本文通过对本区块10个主力层系剩余油分布规律进行数值模拟分析研究,得到油藏剩余油分布主要集中在油藏的西区、北区、中区、东南区,并分区提出了挖潜对策,同时对主力层、非主力层差别化治理,提高油藏整体动用状况。本文对类似油田剩余油分布规律研究有一定指导意义。

After years of waterflood development in X wellblock B block reservoir, its moisture content increases annually and its development effect becomes increasingly worse. Through the numerical simulation and the study of remaining oil distribution in 10 main formation, this passage puts that reservoir residual oil distribution mainly concentrates in the west, north, central, southeast area, and zoning of reservoir and comes out with the measures of potential tapping. And it puts the different treatment to the main layer and other layers to improve overall use of reservoir conditions. This paper can have certain guiding significance to residual oil distribution study of the similar oilfield.
