聚合物驱油后提高采收率优化研究
摘要
Abstract
After polymer flooding in the Lasaxing oilfield, more and more reservoirs have entered subsequent water flooding stage. This paper analyzes the current status of polymer flooding blocks and the potential of improving recovery factor, and determines the distribution of remaining oil and the way of improving recovery factor after polymer flooding. Taking a typical block in the middle block of the North 1 area as an example, this paper researches the feasibilities of layer series and well pattern rearrangement and placing horizontal well in top reservoir, proposes a plan of field test after polymer flooding, and it is anticipated that there will be a 5% increase in recovery factor after implementation of the plan.关键词
