Preparation method and application of super dispersing catalyst for quality improvement and viscosity reduction of thickened oil

The invention discloses a preparation method of a super dispersing catalyst for quality improvement and viscosity reduction of thickened oil. The super dispersing catalyst comprises the following raw materials in parts by weight: 150-200 parts of base oil, 5-15 parts of a surfactant, 1.5-2 parts of a transition metal compound and 1-1.5 parts of a cosurfactant; the preparation method comprises the steps as follows: mixing the raw materials at the temperature of 40-80 DEG C, stirring the mixture for 5-300 min at the speed of 100-8,000 rpm, and performing ultrasound concussion for 10-30 minutes at the ultrasonic frequency of 10-50 KHz to obtain the demanded super dispersing catalyst for quality improvement and viscosity reduction of thickened oil. The super dispersing catalyst can improve the quality of the thickened oil on the spot through the catalytic action, enables chemical bonds with lower bond energy in heavy components to break easily, enables the heavy components to be converted into light components wi
