This invention provides an oleophobic agent for improving wellbore stability, its preparation and application, and a drilling fluid. The oleophobic agent has a core-shell structure, comprising a core structure, a polymer film coating the outer surface of the core structure, and modified inorganic nanoparticles adsorbed onto the polymer film to form the shell structure; or it comprises a core structure and modified inorganic nanoparticles for forming the shell structure, wherein the modified inorganic nanoparticles are adsorbed onto the core structure via electrostatic attraction using a positively charged surfactant; wherein the core structure is selected from particles with a size ranging from submicron to micron. This oleophobic agent possesses a core-shell structure and a dual-level roughness of nano-submicron to micron, which can modify the wettability of rock surfaces to superoleophobic, thereby stabilizing the wellbore by inhibiting the absorption of oil phases into the rock.

The invention relates to the technical field of surface modification, in particular to modified glass glaze and a preparation method thereof, a heating assembly and an aerosol generating device. The modified glass glaze comprises a glass glaze base body, a transition layer and an oleophobic layer which are sequentially stacked in the thickness direction, wherein the transition layer comprises amorphous zirconium silicate; the oleophobic layer comprises a mesoporous inorganic material and a fluorinated organic polymer, and pores of the mesoporous inorganic material are filled with at least part of the fluorinated organic polymer. The thermal expansion coefficient of the transition layer is moderate, so that the whole structure forms a thermal stress gradient buffer system, and the risk of stripping of the oleophobic layer is reduced. The nano confinement effect of the mesoporous inorganic material can significantly improve the decomposition temperature of the fluorinated organic polymer, so that the fluorinated organic polymer can exert oleophobic performance for a long time. Therefore, the modified glass glaze is high in structural stability and excellent in thermal shock resistance, keeps excellent oleophobic performance at a long-term high temperature all the time, effectively inhibits tobacco tar adsorption and carbonization residues, and reduces the risk of cracking of a glass glaze matrix.
