Micro/nano structured oleophobic agent improving the wellbore stability of shale gas wells

Through embedding modified nano-silica particles on the surface of polystyrene using the method of Pickering emulsion polymerization, a kind of nano/micro oleophobic agent named OL-1 was developed. The effects of OL-1 on the rock surface properties and its performance in inhibiting the oil phase imb...
