摘　　要：对准噶尔南缘两口井的钻井液做了高温流变性测试研究。当温度不超过135℃时,两个体系均保持了较好的流变性。随着温度的上升,高剪切速率下的剪切应力变化大于低剪切速率下;两个体系的塑性粘度都略有下降;动切力变化相反。High temperature rheology has been evaluated through Tow types of drilling fluids.They all display well in rheology as test temperature does not exceeded 135℃.With temperature rising,the change of shear stress at high shear rate is more than that at low shear rate,and there are all reduction in PV and contrary to the tow typies in YP.
