The invention relates to gel-foam selective plugging agent and the application thereof, belonging to the technical field of oilfield chemistry. The plugging agent comprises the components: 30-50% of acrylamide, 20-40% of hexamethylenetetramine, 5-15% of phenol, 5-15% of tetraethylene pentamine and 5-15% of foaming agent. The aqueous solution with the mass ratio of 0.5-2% can be prepared in site and is injected into a well after being evenly dissolved, so that the plugging agent is used for plugging water in the oil well at the temperature of 90-150 DEG C. The plugging agent uses organic cross linker for cross bonding polymer to form gel foam under the condition of high temperature, so as to be resistant to the high temperature of 90-150 DEG C and have long period of validity in plugging water.
