摘要:
渤海K油田开发过程中受边水作用较大,由于油藏非均质性较强,边水突进速度较快,导致含水上升速度快,油藏采收率偏低。对油水过渡带注水井调剖能在一定程度上抑制边水突进速度。研究边水对油水过渡带注水井调剖的影响,对油田后期开展调剖决策具有重要意义。通过数值模拟技术和物理模拟技术,研究边水本身的性质(距离和能量)和调剖时机对调剖效果的影响。结果表明:随着水体倍数的增大,调剖效果减弱; 适中的边水距离开展调剖效果较好; 调剖时机越早,提高采收率值越高,早期调剖对采收率提升效果比较显著。
Abstract:
During the development of Bohai K Oilfield, the edge water is significant effect. Because of stronger heterogeneity of reservoir and faster breakthrough of edge water, this can result in rapid rise in water cut and lower oil recovery rate. However, the breakthrough rate of edge water can be controlled by adopting the profile control of water injection wells in oil-water transitional zone. So it was carried out studies on the effect of edge water on the profile control of water injection wells in oil-water transitional zone, which is significant to the profile control decision at later stage of oilfield development. Through the numerical simulation and physical modelling technique, it was studied the effect of the nature of the edge water itself(such as water body size and edge water distance)and profile control timing on profile control effect. The results show that with the water volume multiple increases, the effect of profile control becomes to be poor. Besides, moderate distance of side water is benefit for adopting profile control measures. The earlier the profile control timing, the higher the oil recovery rate is, and the profile control at early stage is significant to improve oil recovery rate.
