摘要: Abstract In order to find out the influence of dilational rheology on chemical flooding systems, Zhuangxi crude oil/NaOH solutions interface was investigated by DSA100 interfacial dilatational rheometer (KRUSS, Germany). The results show that alkaline system, which can enhance oil recovery, mainly depends its rheology, rather than tension. greater elasticity, higher recovery is. viscosity, lower conclusion is consistent with change displacement pressure in macro experiment and sweep efficiency microscopic experiment.
