RHEOLOGICAL CHARACTERISTICS OF DRILLING FLUIDS
Keywords:
Drilling fluid, viscosity, shear stress, shear rate, flushing, velocity, a barite-free fluidAbstract
The article discusses the rheological properties of a high-density,
barite-free drilling mud developed on the basis of formats and polyacrylamide. A
comparative analysis with a traditional barite solution is carried out, including an
assessment of viscosity and shear stress at different shear rates. It has been established
that the non-barite solution has pronounced pseudo-plastic properties, which makes it
more effective when drilling horizontal and directional wells. Recommendations for
the use and control of the parameters of such solutions under drilling conditions are
presented.
