(一)流体类型流变学是研究物体形变及流动特性的一门科学。泥浆具有复杂的流变性能,钻井泥浆在循环系统中由于剪切的差异,流动特性是不同的。泥浆循环系统中各处的剪切速率范围如图1所示。研究流变学对于保持泥浆净化、悬浮岩粉及岩屑能力、适合的压力损
(A) fluid type Rheology is to study the deformation and flow characteristics of a science. Muds have complex rheological properties and flow characteristics are different due to shear differences in the drilling mud in the circulatory system. The range of shear rates throughout the mud circulation system is shown in Figure 1. Research Rheology To maintain the mud purification, suspended rock powder and rock debris ability, suitable pressure loss
