摘要：

三元复合驱是大庆油田聚驱后进一步提高采收率的重要途径，其驱油体系须保证超低油-水界面张力，且能大幅提高波及能力。通过研究烷基苯磺酸盐（ABS）-缔合聚合物（HAPAM）-NaOH三元复合驱体系的性能，并与超高分子量部分水解聚丙烯酰胺（HPAM）三元复合体系进行对比。研究结果表明，HAPAM三元复合体系在NaOH浓度为0.5%~1.2%、ABS浓度为0.025%~0.300%时具有良好的界面活性，油-水界面张力可达10^-3mN/m数量级。0.16%HAPAM-0.3%ABS-1.2%NaOH三元复合体系黏度达108.8 mPa ·s，采用HPAM达到相同黏度其浓度为0.265%，因此HAPAM可降低聚合物用量40%。驱油实验结果表明，在相同黏度下，HAPAM三元复合体系在不同孔隙介质中均能提高聚驱后采收率13%以上，比HPAM三元复合体系多提高采收率6%以上。HAPAM三元复合体系具有更高的阻力系数与残余阻力系数、更好的黏弹性以及乳化稳定性，可以为大庆油田聚驱后提高采收率提供新的技术手段。

Abstract:

Alkaline/surfactant/hydrophobically associating polyacrylamide (ASP) flooding is an important approach for further improving oil recovery after polymer flooding in Daqing oilfield. For cost-effective improvement of oil recovery efficiency, ASP flooding systems must be able to maintain ultra-low oil-water interfacial tension and substantially increase the sweep efficiency. This study evaluates the performance of an alkylbenzene sulfonate (ABS)-hydrophobically associating polyacrylamide (HAPAM)-sodium hydroxide (NaOH) flooding system by comparison with an ultra-high molecular weight, partially hydrolyzed polyacrylamide (HPAM)-ABS-NaOH flooding system. The results show that when the ranges of NaOH and ABS concentrations are respectively 0.5 % -.2 % and 0.025 % -0.300 % , the HAPAM-APS flooding system has high interfacial activity with oil-water interfacial tension decreased to 10^-3 mN/m. The HAPAM-APS solution containing 0.16 % HAPAM, 0.3 % ABS, and 1.2 % NaOH has the viscosity of 108.8 mPa ·s, while the HPAM-APS solution of the same viscosity contains 0.265 % HPAM. That is, compared with HPAM, HAPAM reduces the consumption of polymer in APS flooding systems by approximately 40 % . The oil displacement experiment shows that the HAPAM-ABS-NaOH solution improves oil recovery after polymer flooding by more than 13 % in different porous media at the same viscosity. That is, 6 % more than that by the HPAM-ABS-NaOH solution. Additionally, the HAPAM-ABS-NaOH flooding system has greater resistance factor and residual resistance factor, higher viscoelasticity, and better emulsion stability than the HPAM-ABS-NaOH flooding system. This study indicates that HAPAM-APS flooding provides a new technical approach for enhanced oil recovery in Daqing oilfield after polymer flooding.
