Abstract CLSD is a drilling detergent lubricant made from waste grease under predetermined synthesis process and technical parameters. Laboratory evaluation of CLSD showed that it had good compatibility with other additives, and rendered no bad effect on mud rheology. It moderately reduced API filter loss of the mud. Contact angle of 170.5 °C meant that CLSD was lipophilic. It had
good cleaning and wetting

solution of CLSD was 68.69% lower than that impacting the hole bottor

As temperature went up, the lubricity
le and the friction coefficient of drilling fluids functioned normally at 160 °C or higher. After hot
rolling, drilling fluids treated with CLSD did not foam on the whole. The
CLSD treated drilling fluids is suitable for use in deep wells
and ultra-deep wells, because with an increase in well depth, the property of the drilling fluid becomes more stable. CLSD helped in
reducing chip hold-down effect, thereby increasing ROP; in a laboratory simulation, the ROP was increased by 35.2% Key words Fast drilling agent; Waste grease; increase ROP; Cleaning and wetting; Lubricity; Saturated salt tolerance
