摘要
用一种阳离子酞菁和一种有机聚季铵盐的极低浓度水溶液作驱油剂,与水驱对比在石英砂烧结岩芯上进行了驱替饱和油的实验研究,得到的最终采收率比水驱分别提高5.94%和3.32%。
he flooding chemicals selected in this work are: Aldrich′s dyestuff Alcian Blue 8GX containing 25% cationic copper phthalocianine; Aldrich′s Polybrene, an organic polyquarternary ammonium salt of MW pa 3000. The flooding solutions are: (A)1.298 mg/L Alcian Blue 8GX in 0.1% NaCl solution; (B)0.5 mg/L Polybrene in 0.1% NaCl solution. In coreflow experiments on melted quarz sand cores, it is shown that solution A flood increases oil recovery by 5.55% (on core No1) and 6.32% (on core No2) and solution B flood-by 3.32%(on core No3) comparing with water flood; residual oil satuation in cores No1and No2 is decreased by 3.86% and 5.47%.
