High-temperature resistant permeable artificial borehole wall sand control agent

The invention discloses a high-temperature resistant permeable artificial borehole wall sand control agent, and belongs to the technical field of oil exploitation auxiliaries. The artificial borehole wall sand control agent comprises, by weight, 95-105 parts of solidifying agents, 13-17 parts of filling enhancers, 10-14 parts of sulfonated keto-aldehyde condensation polymer, 9-11 parts of polyamide resin, 0.3-0.7 part of carboxymethyl cellulose and 0.8-1.2 parts of calcium lignosulphonate. The sand control agent is good in temperature resistance (350 DEG C high-temperature resistance), high in permeability (higher than or equal to 0.5dc), high in compressive strength (higher than or equal to 6MPa), strong in washout resistance (5MPa washout resistance), low in material cost, convenient to use and applicable to sand control of oil wells in oil field thermal recovery later period, the sand control agent is mixed with clear water and then pumped into a target layer at oil layer temperature and can be solidified
