The invention provides a curable foaming plugging agent. The curable foaming plugging agent is prepared from the following components in parts by weight: 25 to 55 parts of epoxy resin, 25 to 55 parts of low-viscosity crude oil, 3 to 12 parts of triethylenetetramine, 2.1 to 6 parts of ammonium chloride, 3 to 7.2 parts of sodium nitrite, 5 to 25 parts of water and 0.3 to 1.2 parts of a surfactant. The curable foaming plugging agent provided by the invention is a low-viscosity emulsion solution, the production is simple and safe and side reaction and byproducts are few. The raw materials including a foamable material and the like are adopted, so that the plugging capability is higher than that of common epoxy resin type plugging agents. The raw materials including the low-viscosity crude oil and the like are adopted so that the cost of the curable foaming plugging agent is less than that of the common epoxy resin type plugging agents.
