大庆油田中、低渗透率油层聚合物驱油开发效果

摘要

The pilot test of polymer flooding in the medium and low permeable reservoir (SII10-16 zone) in Sabei thick test area shows that polymer flooding in this reservoir can get nice effect of increasing oil production and reducing water cut. The central well recovery increases 10.15% more than water flooding. Each ton of polymer increases 109 t oil. This enlarges the polymer application field and improves the recoverable reserves.%萨北厚层试验区中、低渗透层(萨Ⅱ10—16层)聚合物驱油矿场试验研究表明，在萨北地区中、低渗透层进行聚合物驱油，同样可以获得较好的增油降水效果。不考虑自然递减，中心井可比水驱提高采收率10.15%,吨聚合物增油109 t；考虑自然递减，中心井吨聚合物增油169 t，为大庆油田拓宽了聚合物驱油的应用领域，提高了可采储量。
