Abstract: Disclosed are a temporary plugging agent and a preparation method thereof, and a method for temporary plugging and fracturing of a high-temperature reservoir. The temporary plugging agent includes the following components in mass fractions: acrylamide 5%, composite crosslinking agent 1%, laponite 1%, ammonium persulfate 0.1% and water 92.9%.

Abstract: The present disclosure provides mint-containing composite cellulose fibers and production methods thereof. A mint-extract crude solution is prepared from a whole mint plant after at least one water extraction process and at least one ethanol extraction process to provide a mint-extract filtrate and mint-extract residues. The mint-extract filtrate is used as the mint-extract crude solution. The mint-extract crude solution is treated to prepare a mint-extract stock solution by at least a quenching process. A viscose spinning solution is prepared by mixing the mint-extract residues with one or more pulps selected from a cotton pulp, a wood pulp, a bamboo pulp, a wool pulp, a linen pulp, a silk pulp, a Tencel pulp, and a Modal pulp. The one or more pulps contain cellulose. A mint-viscose blend is prepared by dynamically mixing the mint-extract stock solution with the viscose spinning solution and then spun into the mint-containing composite cellulose fiber.
