Abstract: High temperature and high density drilling fluid system and application technology is very important to successful drilling of deep and super-deep wells.Few literatures on water-based drilling fluid system that is anti-high temperature of 200 centigrade and density up to 2.30g/cm3 is reported.Under this condition,foreign companies usually choose oil-based drilling fluids.In system design,through choosing agents and adding high temperature stabilizer,water-based drilling fluid and KCl water-based drilling fluid which are anti-high temperature of 200 centigrade and density up to 2.30g/cm3 systems are set up.The systems have good high temperature stabilization,good rheology in HTHP and some inhibition.The systems are meaningful to the choose of drilling muds for deep and super-deep wells.

Key words: water-based drilling fluid, system study, high temperature and high pressure(HTHP), high density, deep well
