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.
