  • As the wells drilled in the Qaidam Basin are becoming deeper and deeper lately, much more attention has been drawn to the performance of high temperature and ultra-high temperature drilling fluids. Laboratory studies have been conducted on the stability, rheology and filtration properties of drilling fluids at ultra-high temperatures. A polyamine organic salt drilling fluid previously formulated was optimized with newly selected high temperature filter loss reducer and shale inhibitor to form a drilling fluid for use in drilling the ultra-high temperature deepened well Kun-2. After aging for 42 h, this new organic salt drilling fluid had HTHP filter loss less than 10 mL. The lithology of the formations penetrated by the well Kun-2 is mainly mudstones and is water sensitive and easy to swell and disperse. Combination of KCl, organic salt and polyamine greatly improved the performance of the drilling fluid, and the percent expansion of mudstone core tested in the drilling fluid was reduced by 93.33%. During drilling, mud losses took place between 6934 m and 6995 m. By adding 5% inert bridging agent ZYD, 3% ultra-fine calcium carbonate QS-4 and 2% gel particles into the drilling fluid, the weathered rock matrix was strengthened after several times of treatment to withstand the pressure exerted by a column of mud of 2.0 g/cm3, a key role in stabilizing the borehole wall and controlling mud losses in an ultra-deep well. With the use of this polyamine organic salt drilling fluid, the deepest well Kun-2 with the highest bottom-hole temperature in Qaidam Basin, was drilled successfully.
