摘要

只有当裂缝中流体的黏度和裂缝尖端的应力保持不变时，超压随时间的变化曲线才能用于预测裂缝的生长模式。实验室数据和现场实例解释了粘性泥浆增加的摩擦力如何影响压裂压力的解释。

The Effect of Viscous Fluid Properties on Excess Friction Pressures Measured During Hydraulic Fracture Treatments

A plot of excess pressure vs. time can be used to predict fracture-growth patterns only when both the viscosity of the fluid in the fracture and the stress at the fracture tip remain constant. Laboratory data and field examples are used to explain how increased friction owing to viscous slurries affects the interpretation of fracturing pressures.
