Effect and mechanism of rheological properties and structure of a novel hydrophobically associating polymer on sand sedimentation rate

Abstract With hydrophobic associating polymer (BCG-1) and anionic surfactant sodium dodecyl benzene sulfonate (SDBS) solution as the object, this work studies different concentration on influence law of fluid properties examines sand sedimentation rate correlation properties. After liquid was tested by electron microscope rheometer, it found that interaction between is with phases, which provided angles for revealing change rule deposition sand. When SDBS in second phase (0.05–0.2%), although system property changes slightly microscopic morphology does not greatly, still decreases significantly. Relaxation time spectrometry explains reduction caused shift chain motion mode, whereas angle can clearly manifest change, highly correlated
