Biomimetic nacre-toughness cement slurry based on in-situ polymerization of fluid loss additive, preparation method and application thereof
Biomimetic nacre-toughness cement slurry based on in-situ polymerization of a fluid loss additive, a preparation method and an application thereof are provided. The preparation method includes: dissolving 2-acrylamido-2-methylpropane sulfonic acid monomer and carboxylic acid monomer in deionized water, adjusting pH to 5.5-6.5, then adding an acrylamide monomer, and uniformly stirring to obtain a monomer solution; adding an initiator and a catalyst into the monomer solution, and then stirring to obtain a pre-polymerization solution; adding cement particles into the pre-polymerization solution under low-speed stirring, and then performing high-speed stirring to obtain the biomimetic nacre-toughness cement slurry. The obtained cement slurry can optimize a microstructure of cement while possessing a well capacity for controlling fluid loss, improve deformation ability and toughness of a cement sheath, and effectively improve brittleness defect of the cement sheath.
