以区块内黄参37井区为研究单元,对研究区内注水开发指标进行了系统评价。以菱形反九点井网进行了注水开发方案设计,并与现有井网条件进行了预测对比。对比结果表明20 a后菱形反九点井网布局的累积产油达到25.49万t,较现有井网在采出程度方面提高了6.17%,反映出注水开发对黄参37井区具有较为显著的增产效果。
Taking the yellow ginseng 37 well block in the block as the research unit, the authors made a systematic evaluation of the waterflood development index in the study area. The design of water injection development scheme was carried out with rhombic anti-nine-dot pattern, and compared with the existing well patterns. The comparison results show that after 20 years, the cumulative production of rhombus anti-nine-dot pattern network reaches 254,900 t, which is 6.17% more than that of the existing well pattern, which shows that the water injection development has a significant effect on Huang-37 The yield effect.
