如果产出盐水中的阻垢剂 (SI) 浓度高于某个特定浓度（即最低抑制剂浓度），则使用阻垢剂挤压处理可以保护油井。普遍认为，阻垢剂的保留水平受吸附和沉淀机制控制。最近的实验得出结论，在低浓度下，吸附作用比沉淀作用更显著。为了检测当 SI 的保留受吸附和吸附/沉淀机制控制时出现的表面沉积物，我们在内部构建的微岩心驱替系统中使用了高分辨率 X 射线计算机断层扫描 (CT)。

Scale-inhibitor (SI) squeeze treatments will protect the well if the concentration in the produced brine is above a certain concentration, known as the minimum inhibitor concentration. It is generally accepted that retention level is governed by adsorption and precipitation mechanisms. Recent experiments concluded that adsorption is more dominant than precipitation at low concentrations. To detect surface deposits occurring when the SI retention is governed by an adsorption and adsorption/precipitation regime, high-resolution X-ray computed tomography (CT) scanning was used in an in-house-built minicoreflood system.
