Study of scale formation in water pipe of BF cooling stave and its main influence factors;

Corrosion and scale deposit reasons of tubes were discussed, through the in-situ investigation, produced water composition analysis, XRD analysis of scaling samples of single well in Western oilfield, combining scaling prediction and corrosion rate monitor.

In view of the present situation and characteristics of the scale deposit in Longdong Oilfield,this paper analyses the mechanism and the influence factors of scale deposit.

This study indicated that the the scale deposit didn't have much to do with the formation water carried by the gas and it was mainly resulted from acid gas corrosion and bacteria corrosion.
