Oil well cement thixotropic agent and preparation method thereof
The invention relates to the technical field of oil well cement additives, and discloses an oil well cement thixotropic agent and a preparation method thereof. The method comprises the following steps: adding distilled water into a container; adding 10-50 parts of 2-acrylamido-2-methylpropanesulfonic acid and 5-15 parts of acrylic acid into the container, and dissolving by stirring; regulating the pH value of the substance in the container to 6-7; adding 35-80 parts of acrylamide and 5-30 parts of cationic monomer, and dissolving by stirring; heating the container, and adding an initiator to initiate the polymerization reaction to obtain an amphoteric polymer; and mixing superfine clay and the amphoteric polymer in a mass ratio of 10:1 to obtain the oil well cement thixotropic agent. The oil well cement thixotropic agent solves the technical problem of low thixotropy, low sensitivity to temperature and low comprehensive properties in the oil well cement thixotropic agent in the prior art, and better implements the technical effects of plugging the loss zone and preventing the fluid cross flow.
