Influence de l’inhibiteur anti dépôts (AD32) Sur la croissance de dépôts de sulfates de baryum

Abstract

Barium sulphate deposits pose many problems for oil wells and hydrocarbon production and processing facilities. This type of deposit occurs, when the water injected for the recovery of hydrocarbons is incompatible with the reservoir water. The main objective of this work is to study the inhibition of barium sulphate deposition by AD32 antideposition and determine the effectiveness of the latter. Initially, we studied the case of OL6 well using the PROSPER software and also identification analyzes of BaSO4 deposits that were carried out at laboratory level of SONATRACH DP (IRARA). Then for the optimization, in an ambient and reservoir temperature, we studied the influence of parameters such as pH and concentration of AD32 on the rate of inhibition of deposits, using the MODDE 6.0 software. Finally, in the last part, we proposed a new adsorbent (carbon nanospheres) to treat the injected water in order to solve the BaSO4 deposit formation problem
