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

以疏水缔合聚合物（BCG-1）和阴离子表面活性剂十二烷基苯磺酸钠（SDBS）溶液为对象，研究了不同聚合物浓度和表面活性剂浓度对流体性质的影响规律，考察了砂沉降速率及其相关性。流体特性。用电镜和流变仪对液体进行检测后发现，表面活性剂与聚合物的相互作用是有相的，为揭示砂粒沉积速率的变化规律提供了不同的角度。SDBS溶液浓度为第二相（0.05-0.2%）时，虽然体系性质变化不大，微观形貌变化不大，但砂的沉积速率仍显着下降。
