The development and application of on-line acoustic scale prevention technology;

Scaling mechanism and scale prevention techniques of weak base Alkaline-Surfactant-Polymer flooding;

This paper provides an overiew of scale prevention and scale removal method in vacuum salt making.

Among many anti-scaling techniques for oilfield water injection pipeline network,the chemical anti-scaling technique is still in common use at oilfields at present.

In this paper,the disadvantage in conventional ways of anti-scaling are summarized,mechanism of ultrasonic anti-scaling is discussed,application of ultrasonic s anti-scaling is introduced from five aspects.

The paper summarized the anti-scaling,scale removal and sterilization theories,and nowaday research of magnetic treatment,showed the foreground of application in thermal power plant.

The application of TRASAR and A-Z Lite programs to the optimization of the running modification of water saving and scale inhibition is introduced.

To investigate the scale inhibition mechanism of HEDP,a classic scale inhibitor,the Zeta potential of fresh CaCO_3 originated from admixture of equimolar of Ca~(2+) and CO~(2-)_3 was measured in time during precipitating process.
