Study on Viscoelastic Low Molecular Weight Plant Gums as Fracturing Fluids

摘要

In this paper, the low molecular weight plant gum (guar) as fracturing fluids were prepared and the rheological properties for the low molecular weight plant gum fracturing fluids were studied. The results showed that, the fracturing fluids possess viscoelasticity and shear thinning properties. The non-linear modified Williamous-Oldroyld-4-parameter constitutive equation was proved to describe the flow curves of the fracturing fluids, the calculated values were in good agreement with the experimental data.
