1. Product introduction
Polystyrene (zr-04) modified by flow pattern regulator for oil-based drilling fluid was prepared by copolymerization with styrene as the main raw material and octadecyl methacrylate and maleic anhydride as auxiliary materials. It can effectively increase the viscosity and shear force of drilling fluid, is more conducive to the control of fluidity of oil-based drilling fluid with high density and high solid content, and has good environmental acceptance. It can effectively improve the thixotropy of oil-based drilling fluid, improve the low shear rate viscosity of drilling fluid and enhance the suspension stability of oil-based drilling fluid. The temperature resistance can reach 200 ℃.
