Study of steam heat transfer enhanced by CO2 and chemical agents: In heavy oil production
Petroleum Science(2023)
Abstract
Steam flooding with the assistance of carbon dioxide (CO2) and chemicals is an effective approach for enhancing super heavy oil recovery. However, the promotion and application of CO2 and chemical agent-assisted steam flooding technology have been restricted by the current lack of research on the synergistic effect of CO2 and chemical agents on enhanced steam flooding heat transfer. The novel experiments on CO2–chemicals cooperate affected steam condensation and seepage were conducted by adding CO2 and two chemicals (sodium dodecyl sulfate (SDS) and the betaine temperature-salt resistant foaming agent ZK-05200).
