DEVELOPPEMENT D’UNE TECHNIQUE D’EVALUATION DES INHIBITEURS DES DEPOTS DE SEL (NaCl)

Abstract

The production of oil often requires enormous quantities of water. Most of this water is used in washing of the salted wells in order to fight against the NaCl solid deposits. In Algeria, the water used is drawn from fresh groundwater. These waters once used are thrown back into nature with their polluting hydrocarbons load. In order to the objective to reduce the volume of waters used in the washing of the salty wells, we tested in the laboratory three methods to estimate the efficiency of the inhibitory products of the NaCl deposits. The obtained results show that it is possible to select in the laboratory the appropriate treatment products. The use of these products will allow us to reduce the volumes of water used for the washing of salts. This reduction is synonymous of a reduction of the pollution on one hand, and a protection of our water resources on the other hand.
