It has obvious actions of leakproof and lost circulation in low pressure absorbent formation because of containing a lot of foam with high shear force and high structuralviscosity.
由于含有大量高切力、高结构粘度的泡沫,在低压渗漏地层有显著的防漏堵漏作用。

The change of viscosity, structural thixotropy and foundation of rheologic model provide experimental evidence for evaluating, prognosticating and altering the technical performance of coating.
