Embodiment 1

[0030] Add 0.1 mol of industrial grade octylphenol polyoxyethylene ether OP-4 into the reactor with stirrer and thermometer, heat and stir at 60°C for 1h, then add 0.15mol of propionyl chloride into the reactor, heat up to 90°C, After reacting for 1h, cool to room temperature to obtain octylphenol polyoxyethylene ether propionate; then add 0.6mol of ethylene dichloride as a reaction solvent in the reactor containing octylphenol polyoxyethylene ether propionate, and react The reactor was transferred to an ice-water bath, and reacted with 0.12mol chlorosulfonic acid for sulfonation, and the reaction time was 0.5h. After the sulfonation was completed, the reactor was transferred to an oil bath and heated to 80°C for 1h to obtain octylphenol polymer Oxyethylene ether propionate sulfonic acid; finally, add 0.05 mol of nickel hydroxide to the reactor containing octylphenol polyoxyethylene ether propionate sulfonic acid, heat up to 120°C and stir for 1 hour, and let stand after the re...

Abstract

The invention relates to an aquathermolysis catalytic viscosity breaker and a preparation method thereof, belonging to the technical field of oilfield chemistry. The aquathermolysis catalytic viscosity breaker has the following structural general formula, wherein X is 7 or 8, Y is 4-10, Z is 3-6, M is a transition metal hydroxide, and the molecular weight is 2000-5000. The alkylphenol-polyoxyethylene-structure-containing organic acid is designed and synthesized as the ligand, the ligand can carry transition metals to diffuse and permeate into the high-molecular associated structure of the thick oil heavy component and sufficiently contact the heteroatoms in the high-molecular associated structure to take effect, thereby promoting the removal of partial heteroatoms, and better displaying the catalytic activity of the aquathermolysis catalytic viscosity breaker. The aquathermolysis catalytic viscosity breaker can be used for aquathermolysis catalytic viscosity breaking exploitation of super-heavy oil, is simple in preparation technique, and has high universality and salt resistance for thick oil in different regions.

Description

technical field [0001] The invention relates to a hydrothermal cracking catalytic viscosity reducer and a preparation method thereof, which belongs to the technical field of oil field chemistry and can be widely used in the crude oil viscosity reduction process of heavy oil exploitation. Background technique [0002] With the continuous development of the global economy, energy consumption continues to grow. As an important part of global petroleum resources, heavy oil has resource potential several times higher than conventional petroleum resources. Although the current oil price is low and the global petroleum industry has entered an extremely cold winter, but With the gradual reduction of conventional light oil resources, heavy oil resources will still play a pivotal role in the future world energy supply. [0003] The core of heavy oil development is to achieve a large viscosity reduction of heavy oil, so that it has good fluidity during wellbore lifting and formation se...
