▎ 摘  要

NOVELTY - Shale oil shale gas fracturing temporary plugging agent comprises modified polyacrylamide, high-temperature stabilizer, toughening agent, thickening agent and dispersant. The modified polyacrylamide is prepared from raw materials comprising acrylic acid, acrylamide, guarana gum, crosslinking agent, oxidizing agent, reducing agent, graphene oxide, inorganic nanoparticles and silane coupling agent. USE - As shale oil shale gas fracturing temporary plugging agent. ADVANTAGE - The temporary plugging agent has excellent plugging effect in a short time and effective for a long time until the entire repeated fracturing construction is completed, and is completely degraded or dissolved, which improves the use efficiency of the temporary plugging agent and the success rate of repeated fracturing. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the shale oil shale gas fracturing temporary plugging agent, which involves dripping high-temperature stabilizer, toughening agent, thickening agent and dispersant under the condition of agitator stirring, completely stirring, heating at 30-40 degrees C, continuously adding modified polyacrylamide, and continuously stirring.
