摘要：NOVELTY - The high-temperature-resisting thick oil viscosity reducer is formed by mixing surfactant (in parts) (1), accelerant (0.2) and regulator (8-60). The surfactant is obtained by neutralization-reacting organic acid and alkali (1). The accelerant is hydrocarbon or hydrocarbon oxide. The regulator is sodium hydroxide, potassium hydroxide, sodium carbonate, sodium bicarbonate, potassium carbonate, potassium bicarbonate, sodium phosphate, potassium phosphate and potassium hydrophosphate. USE - High-temperature-resisting thick oil viscosity reducer. ADVANTAGE - The High-temperature-resisting thick oil viscosity reducer has excellent temperature-resisting characteristics and workability, and is economically manufactured using simple method. DETAILED DESCRIPTION - The high-temperature-resisting thick oil viscosity reducer is formed by mixing surfactant (in parts) (1), accelerant (0.2) and regulator (8-60). The surfactant is obtained by neutralization-reacting organic acid and alkali of formula (1): X-Y'-Z. The accelerant is hydrocarbon or hydrocarbon oxide. The regulator is sodium hydroxide, potassium hydroxide, sodium carbonate, sodium bicarbonate, potassium carbonate, potassium bicarbonate, sodium phosphate, potassium phosphate and potassium hydrophosphate.
