The invention discloses a low-temperature delayed-curing sand-control proppant, a preparation method of the proppant as well as a low-temperature delayed-curing sand-control system. The sand-control proppant comprises proppant particles, wherein proppant particles comprise quartz sand and composite resin layers, and the composite resin layers comprise inner resin layers and outer resin layers; the inner resin layers are thermoplastic phenolic resin layers; the outer resin layers comprise components in parts by weight as follows: 1.0-3.5 parts of mixed resin, 0.01-0.02 parts of a resin curing agent, 0.005-0.02 parts of a silane coupling agent and 0.05-0.1 parts of a dispersant; the mixed resin is a mixture of thermoplastic phenolic resin and epoxy resin; the mass ratio of the quartz sand to the inner resin layers to the mixed resin of the outer resin layers is 100:(0.5-2.0):(1.0-3.5). The temperature resistance and the compressive strength of the sand-control proppant are improved by the aid of the composite resin layer, and the sand-control proppant can be cured at the low temperature and even the normal temperature and can be adapted to stratums at different temperatures.
