泡沫液配方优选

Optimization of foam liquid formulation

随着油田进入高含水期,由于储层的非均质性质以及注水的高流度比造成剩余油富集区,如何对这一剩余油富集区进行开采成为越来越重要的问题。通过空气泡沫驱可以增加驱替剂粘度,降低油水流度比,增加该区域储量动用程度,本文对泡沫液的优选进行了研究。

In view of oilfield going into high water cut stage and remaining oil enriched area caused by non-homogeneousreservoir and high-mobility-ratio injection,the way to explore this remaining oil enriched reservoir has become an increasinglyimportant issue. Air foam flooding can be applied to increase the viscosity of displacing agents,reduce oil/water mobility ratio andimprove reserves producing degree in this area. Foam liquid optimization is studied in this paper.
