چکیده
|
One of the most important challenges during water injection into oil reservoirs is the formation of inorganic scale due to incompatibility of injection water and formation brine# in this study, injection water compatibility study for evaluation of barium sulfate scale formation were carried out for one of the iranian oil fields located in persian gulf# the laboratory experiments were performed with synthetic formation and injection waters at reservoir temperature#sensitivity analysis was carried out on mixing ratio of formation water to injection water and injecteion water salinity to determine the condition of minimum barium sulfate scale formation# results showed that barium sulfate scale is formed at any ratio of injection water and maximum precipitation was observed at 90% formation water# by increasing the temperature, barium sulfate solubility increases and therefore, turbidity of waters mixture was decreased# as injection water salinity is decreased, solution turbidity and the amount of sulfate scale decreased# overall, damage potential of barium sulfate scale should be considered for water injection operation in the studied oil field#
