Application of Chemical Flooding in Increasing Yield of Tertiary Oil Recovery

Abstract

This paper mainly explores the application measures of chemical flooding in increasing yield of tertiary oil recovery to. In the research process, taking the overview of tertiary oil recovery as the starting point, analyze that oil extraction can be divided into three stages, tertiary oil recovery as the last link, and the crude oil recovery rate needs to be improved. On the basis of this research, the application mechanisms of polymer flooding, alkaline flooding, surfactant flooding, and ASP flooding are proposed, make actual application measures are clear, so as to provide references for related workers.
