Beschreibung
Zusammenfassung:	The invention relates to a thermal-recovery injection well gel single-liquid modifying and flooding agent and a modifying and flooding method thereof. The thermal-recovery injection well gel single-liquid modifying and flooding agent is a black brown solution formed by dissolving and mixing 8wt%-10wt% (in percent by weight) of sodium nitrohumate, 2.1wt% of formaldehyde, 2.5wt%-2.75wt% of resorcinol and 0.015wt%-0.035wt% of HPAM (hydrolyzed polyacryamide) under normal temperature in formation water, wherein the sodium nitrohumate is industrial sodium nitrohumate. The thermal-recovery injection well gel single-liquid modifying and flooding agent disclosed by the invention adopts a single-liquid method injection process, is simple to construct and prepare, capable of sufficiently reacting underground, and high in effective utilization rate.
