油藏油水运动规律研究

Study on movement regulation of oil and water in the permeability reservoir

油田在注水开发过程中,油水运动规律将变得越来越复杂。而油藏的油水运动制约着油田的开发效果。因此,必须准确掌握油藏的油水运动规律,才能有效地控制地下油水的运动。为此,将整个区块的油水相对渗透率曲线转化为含水饱和度与油水相对渗透率比值之间的关系曲线。然后结合产水率的含义分析了油井的产水规律。在此基础上,结合该区块的平均毛管压力曲线研究了油水在垂向和径向上的分布及其运动规律。为油田开发后期调整挖潜决策提供了一定的依据。

In the process of water injection, become more complex. The movement of oil Therefore, only if we master the movement the and movement regulation of oil and water will water restrict development effect of oilfield. regulation of oil and water, we can efficiently control the movement of oil-water. According to this situation, we can change the oil-water relative permeability curves into the relation curve between water saturation and the ratio of the oil-water relative permeability curves. And then, combine with the meaning of water production ratio, we analyze the regulation of water production. On this basis, combined with the average capillary pressure curves in this block, we study the movement regulation of oil and water in the vertical and radial distribution. In doing so, we can provide some proof for oilfield development decision-making and later adjustments.
