Beschreibung
Zusammenfassung:	An enhanced oil recovery method includes: screening out implementation well that meet the requirements of a preset standard; selecting the target interval that can be used for enhanced oil recovery in the implementation well; obtaining the reservoir parameters and perforation parameters of the target interval, so as to divide the target interval into several groups of swallowing and exhaling segments, injecting the infection liquid containing and simmer the well for a period of time; and after the well simmering, the oil-water mixture replaced by the injection fluid is produced from each exhaling segment.
