The self-growing soft elastic particles are prepared by polymerization and crosslinking, curing enzyme and activation addition, which have the characteristics of viscoelasticity, controllable particle size and high content. The polymerized soft particles immobilize the active enzyme, and can continue to react under the formation to make it have high strength and self-growth characteristics, thus forming a 'strong and effective' plugging of the formation, which is suitable for deep formation flooding.
