水驱优势通道对水驱开发效果的影响研究

Effect of Dominant Channel of Water Flooding on the Development Result

提出了水驱优势通道的概念。采用流线数值模拟技术研究了优势通道属性对水驱开发效果的影响。研究结果表明优势通道是通过影响油藏中生产井和注水井控制的油藏体积来影响水驱开发效果的。对于存在优势通道的油藏 ,水驱开发中存在两种流线 :一种是从井筒出发平行优势通道的流线 ,另一种是从优势通道出发垂直于优势通道的流线。

The concept of dominant channel of waterflooding is put forward, a streamline based numerical simulating technique is used to study the effect of the dominant channel attribute on reservoir development. The result shows that the influence of dominant channel on the development effect of water flooding is implemented by reservoir volumes controlled by production and injection wells in the reservoirs. For the reservoirs with dominant channels, there exist 2 types of streamlines: one is parallel to the dominant channel started from wellbore, the other is perpendicular to the dominant channel from the channel, the influence on the recovery of water flooding comes from both lines.
