    Abstract
  • 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 optimiz
