Intelligent diverting agent for coal bed gas exploitation and preparation method thereof

The invention discloses an intelligent diverting agent for coal bed gas exploitation and a preparation method thereof. The intelligent diverting agent comprises the following components according to weight percentage: 5%-15% of glucosamine hydrochloride, 10%-20% of N-methyl-D-glucosamine hydrochloride, 1%-20% of a water-soluble regulator, 0.2%-0.5% of a surfactant, 0.1%-0.2% of a dispersing mutualsolvent, 5%-20% of acrylamide, 1%-10% of N, N-methylene diacrylate, 5%-10% of an accelerant and 50%-60% of water. The intelligent diverting agent is in a liquid state under the ground condition and is low in viscosity and has good injectivity; after the intelligent diverting agent is injected into a coal seam, the intelligent diverting agent can be stimulated by temperature to be changed into thesolid state from the liquid state under the low-temperature condition of the coal reservoir, the phase change time can be adjusted by adjusting the temperature without adding other temporary pluggingagents, and formed solid-p
