The shaft frictionvalue is still in the linear growth phase. The self-balanced method may resolve the problem that the shaft friction is not ful used in Guizhou Province.
Field using verified that the fluid possesses good gel breaking property, the operating frictionvalue is low, the proppant carrying ability is strong and fracture length is in control.
现场实验表明,清洁压裂液具有破胶性能,施工摩阻低,携砂能力强,可有效地控制缝高。

We will do that later until it starts to slip and then at that critical angle that it starts to slip you have a value for mu of s for the static friction coefficient.
