Abstract

We investigated the performance of DH-A series of flooding system, which consists of hydrophobic association polymer (HAP) (Provided by Sichuan Guangya Technology Co., Ltd.), Alkali (NaOH) and Surfactant (heavy alkylbenzene sulfonate ), under the reservoir conditions in Daqing. The detailed composition of ASP system included 0.08 ~ 0.16 (wt)% of HAP, 0.025-0.3 (wt)% of surfactant, and 0.4 ~ 1.2 (wt)% of NaOH. The viscosity of the system is over 40mPa.s and Daqing crude oil/water interfacial tension can reach 10^-3mN/m. This system increases the recovery after polymer flooding by more than 10% in both artificial and natural heterogeneous core flooding experiments.
