The embodiments of the invention provide an intelligent prediction method and apparatus for reservoir sensitivity, belonging to the technical field of reservoir sensitivity prediction. The method includes: acquiring a reservoir sensitivity influence factor item related to a reservoir sensitivity result to be predicted and numerical values of corresponding reservoir sensitivity influence factors; determining a corresponding type of database according to the reservoir sensitivity influence factor item; determining whether numerical values of reservoir sensitivity influence factors corresponding to core parameters in the numerical values of the reservoir sensitivity influence factors include a first upper boundary value or a first lower boundary value; and using, according to whether the first upper boundary value or the first lower boundary value is included, different intelligent sensitivity prediction models to calculate the reservoir sensitivity result to be predicted.

The present invention discloses temporary plugging agent for drilling fluid and preparation method thereof, and water-based drilling fluid and use thereof. The temporary plugging agent for drilling fluid is obtained by controlling gelatinized starch and a vinyl grafted monomer to have a polymerization reaction in an activator solution in the presence of a cross-linking agent and an initiator; the vinyl grafted monomer comprises acrylic acid, acrylamide, and 2-acrylamide-2-methyl propanesulfonic acid; the gelatinized starch is obtained by adding starch into deionized water to have a gelatinization reaction.
