各向异性多层砂岩油藏矢量化井网研究

Study on Anisotropy Multilayer Sand Reservoir with Vectorization Well Pattern

基于同一层系内部不同方向性的纵向多层组合,将数值模拟技术与矢量化井网概念相结合,研究不同渗透率方向性组合下同一层系的五点法和反七点法的部署模式。结果表明,适当的井网方向性能够改善此类开发层系的注水开发效果。

Based on the difference between layer system,which overlooks the anisotropy between the sublayer of layer system,the paper combines the numerical simulation technique and vectorization well pattern. And it studies five-spot pattern and reverse seven-spot pattern in one layer system that includes the combination of difference permeability orientation. The result shows that appropriate directivity in well pattern may improve the effect of waterflood development in this layer series of development.
