We introduce the maintypes ,mechanism and predicting
methods of inorganic scaling of field water. The article covers
four topics :firstly ,why the field water forms scale ,the steps ,
mechanism and influence factors of scale formation ;
secondly ,using the index of saturationg to predict the scale
formation of carbonate ; thirdly , predicting the scale
formationg of sulfate by using the index of RI ;and fourthly ,
if the scale formation has formed ,how much scale there will
have and how the scale ions distribute. The technology of
inorganic scaling prediction will be very helpful to the
working of scaling prevention and descaling in oil field.
