Abstract: Disclosed is a high-temperature resistant nano composite mining additive for mining heavy oil and super heavy oil, which is prepared from 3-8 wt. % of a modified nano-inorganic additive, 3-8 wt. % of petroleum sulfonate, 10-40 wt. % of a viscosity depressant, 5-15 wt. % of an emulsifier, 2-10 wt. % of a surface wetting agent, 2-10 wt. % of a penetrant, 5-10 wt. % of a polymer modifier, and 1-8 wt. % of a catalyst, with a balance being water. Also disclosed is a preparation process for the above-mentioned high-temperature resistant nano composite mining additive for mining heavy oil and super heavy oil. The mining additive of the present invention has the advantages of a good high-temperature resistant performance, and an excellent emulsification performance and anti-salt performance, thereby significantly improving the efficiency of production and reducing the cost of mining.
