钻井液的流变特性是钻井过程的重要指标。在钻井过程中,用简便且快速的方法调节泥浆的粘度或流变特性,已成为钻井技术人员经常必需的指南。实际上,钻井液的流变特性直接影响各种作业的进行;同时,随泥浆粘度增高,特别是表现粘度高时会妨碍钻头对孔底的切削和破碎岩石,也易造成泥包钻头,增加泵压损失等,这样影响机械钻速,降低效率;另外流变特性对携带岩屑, Drilling fluid rheology is an important indicator of the drilling process. It has become a often-needed guide for drilling technicians to adjust the viscosity or rheology of muds in a simple and fast way during drilling. In fact, the rheological properties of drilling fluid directly affect the operation of a variety of operations; the same time, with the increase of the viscosity of the mud, especially when the viscosity is high, will hinder the drill bit from cutting the bottom of the hole and crushing the rock, Pump pressure loss, etc., this affects the rate of penetration, reduce efficiency; In addition rheological properties of carrying debris,
