Low-temperature curable nano-modified resin coated proppant suitable for hydrate reservoir and preparation method of low-temperature curable nano-modified resin coated proppant

The invention discloses a low-temperature curable nano-modified resin coated proppant suitable for a hydrate reservoir, which comprises a component A and a component B in a weight ratio of 1: 1. The component A comprises the following components in parts by weight: 100 parts of resin coated quartz sand, 2-6 parts of a curing agent, 1-4 parts of a dispersing agent and 0.2-0.8 part of a surfactant; the component B comprises the following components in parts by weight: 100 parts of resin coated quartz sand, 2-6 parts of a curing accelerator, 1-4 parts of a dispersing agent and 0.2-0.8 part of a surfactant. Wherein in the resin coated quartz sand, the weight ratio of the quartz sand to the nano silicon dioxide modified phenolic resin to the nano silicon dioxide modified phenolic resin to the coupling agent is 100: (12-16): (4-8): (2-8). The proppant can be cured at the low temperature of 12 DEG C or above, a solidified body with effective strength can be formed after curing, and hydrophobic microchannels can be f
