摘要: 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.

摘要: The invention relates to the field of petroleum drilling fluids, and discloses a super-amphiphobic strongly self-cleaning high-performance water-based drilling fluid comprising polymeric super-amphiphobic agent and a drilling method. The polymeric super-amphiphobic agent comprises structural units A derived from acrylamide, structural units B derived from methyl methacrylate, structural units C derived from butyl acrylate, structural units D derived from a compound represented by the following formula (1), structural units E derived from a silane coupler, and nano-titania; wherein the nano-titania is bonded to the polymeric super-amphiphobic agent via the structural unit E, and the silane coupler is a silane coupler having double bonds; R is a C3-C8 perfluoroalkyl group. A water-based drilling fluid additive prepared from the polymeric super-amphiphobic agent in the present invention has excellent wettability, inhibition, lubrication, reservoir protection, and rheology and fluid loss properties.
