针对利29块高温高盐的油藏特点,研制成功了耐盐能力80000mg/l,耐温超过85-90℃的新型交联聚合物体系。再此基础上进行了物理模拟和数值模拟研究,对交联聚合物驱浓度、段塞尺寸等参数进行模拟,优选出了交联聚合物驱的工艺方案,并对其驱油效果进行了预测及评价。 Aiming at the characteristics of 29 reservoirs with high temperature and high salinity, a new type of cross-linked polymer system with salt tolerance of 80000mg / l and temperature of over 85-90 ℃ was successfully developed. On the basis of this, the physical simulation and numerical simulation are carried out to simulate the flooding concentration of crosslinked polymer and the size of slug. The technological scheme of cross-linked polymer flooding is optimized and the flooding effect is predicted And evaluation.
