A biodegradable modified coating, a modified knot plugging agent for fracturing and its preparation method

This invention provides a biodegradable modified coating, a modified knot plugging agent for fracturing, and their preparation method, belonging to the field of tertiary oil recovery technology. Specifically, the dense cross-linked network structure generated by the Schiff base reaction between gelatin (GL) and glutaraldehyde (GD) serves as a coating material for the knot plugging agent, providing it with high strength and stability without sacrificing its biodegradability. Furthermore, by changing the reaction conditions (immersion time and curing time) during the preparation of the coated knot plugging agent, a series of knot plugging agents adaptable to different reservoir temperatures and degradation cycles can be obtained to meet the complex conditions in perforation cluster plugging processes, thus broadening its application range.
