As a nano polymer plugging agent for oil-based drilling fluid, the nanoparticles of RMD-24M can effectively reduce the permeability of filter cake, reduce HTHP filtration, reduce the invasion of oil-based drilling fluid and its filtrate into the formation, and improve borehole stability. Different from traditional oil-based drilling fluid plugging materials, RMD-24M nanoparticles can block nano-sized micro fractures in shale, so as to prevent pressure transmission and improve borehole stability. The size of RMD-24M nanoparticles is very small so that they can enter the gap between friction bodies, fill grooves and cracks, reduce surface roughness and effectively reduce friction. In addition, RMD-24M long-chain structure contains hydrophilic and hydrophobic groups, which has a certain emulsification effect, can help to improve the demulsification voltage of oil-based drilling fluid and contribute to the stability of oil-based drilling fluid system.
