摘要(Abstract):
为了评价聚合物交联微凝胶的调驱效果 ,了解聚合物交联微凝胶驱动态反应特征并探索聚合物交联微凝胶驱油机理 ,在具有河南油田油藏地质特征的五点法井网、纵向非均质物理模型上进行了驱替实验。实验结果表明 ,与聚合物驱相比 ,由于聚合物交联微凝胶在多孔介质内滞留量大 ,流动能力差 ,注入压力高 ,因而调驱效果好。在聚合物驱及聚合物交联微凝胶驱后 ,地层内剩余油主要分布在中、低渗透层 ,这是进一步提高采收率的潜力所在
According to evaluate the displacement controlling effect of polymer cross link micro gel and understand its dynamic reflection characteristic and its displacement mechanism, a displacement experiment is performed in five point pattern with the reservoir geologic characteristic of Henan Oil Field and vertical heterogeneous physical model. The result shows that, compared with polymer flooding, polymer cross link micro gel has more remaining amount in multi porous, poor mobility and high injection pressure, so it has a nice profile controlling displacement effect. After polymer flooding and polymer cross link micro gel flooding, the residual oil mainly distributes in middle and low permeable reservoirs. This is the potential area of EOR.
