KPF high-performance water-base drilling fluid

The invention discloses KPF high-performance water-base drilling fluid. Clear water is used as a medium; the KPF high-performance water-base drilling fluid is prepared and obtained by mixing the following raw materials according to a proportion: bentonite (NV-1), sodium carbonate (Na2CO3), potassium hydroxide (KOH), polyanionic cellulose (LV-PAC), potassium chloride (KCI), polyamine, polymeric aluminum (AOP-1), chromium-free sulfonated lignite (M-SMC) or disperse diluting agent, extra-grade sulfonated asphalt powder (ST-2), sulfonated asphalt (FT-1) or oil-soluble resin (SCL), emulsifying agent (SEA), nano calcium, rigid micron-nano blocking agent (AT), extreme-pressure lubricant (SDPH-1), extreme-pressure lubricant (SDPH-2), extreme-pressure lubricant (SWJH) and olein lubricant (CGY). The KPF high-performance water-base drilling fluid is the technique of pure water-base drilling fluid, and is environment-protection-friendly drilling fluid; the environment-protection treatment expense is decreased; homemade m
