Abstract:

Hydrocolones used for used for separating the sand in producing fluid are different from those used for processing drilling fluid in their working conditions and service requirements. According to these differences，this paper discusses，by means of indoor hydrocolone test, the main factors affecting the separating effect of hydrocolones used for separating the sand in producing fluid，and points out the main features of hydrocolones in design and use.

Key words: Cyclone desilter, Cyclone separator, Solid liquid separation, Design, Analysis
