屈服点（yp）是什么意思？
屈服点通常被定义为材料将永久地失去其弹性和变形的弹性极限。对于钻井液，屈服点是指流体的初始流动的电阻或换句话说，所需的应力开始流体的运动。它是宾果塑料模型的参数。
钻井液中胶体颗粒之间的吸引力将防止流体流动，直到施加所需的应力。

一世n the Bingham plastic model yield point is the shear stress extrapolated to a shear rate of zero. It is calculated from the 300-600 rounds per minute (rpm) viscometer dial readings by negating the plastic viscosity from the 300 rpm dial reading. Yield point gives an indication of the ability of the drilling mud to lift or remove the cuttings out of the annulus.
一种drilling fluid with higher yield point will carry cuttings better than that with lower yield point.
