Research progress and application status of colloidal gas aphron(CGA)fluid in fracturing and enhanced oil recovery(EOR)
This paper summarized the research progress and application characteristics of foam fluid in fracturing and EOR,and proposed that foam fluid still has problems such as insufficient stability in the formation environments,limited EOR improvement,and reservoir damage.The colloidal gas aphron(CGA)fluids,analyzed and demonstrated that CGA,as a fracturing fluid and displacement fluid,has good appli-cation prospects in EOR,and puts forward prospects for its future research.
