摘　　要：为分析水基钻井岩屑固相颗粒在甩干机中的运移机理,并研究甩干机关键参数对处理量和分离效率的影响,采用FLUENT对水基钻井岩屑的分离进行数值模拟研究。研究结果表明,固体颗粒粒径越大,甩干机分离效率越高,在处理200 μm固相颗粒时有较好的处理效果。优选筛网尺寸为0.50 mm、甩干机转速差为7~10 rpm、泥浆密度范围为1840~1920 kg/m^(3)。To analyze the transport mechanism of solid particles in water-based drilling cuttings within a centrifuge and to study the effects of key parameters of the centrifuge on processing capacity and separation efficiency,this paper uses FLUENT for numerical simulation.The results show that the larger the particle size,the higher the separation efficiency of the centrifuge.The centrifuge performs best when processing 200μm solid particles.The optimal screen size is 0.50mm,centrifuge speed differential is 7~10 r/min,and mud density range is 1840~1920 kg/m^(3).
