The scaling conditions for ASP flooding oilfield in the fourth Plant of Daqing oilfield

The fourth Plant of Daqing oilfield which uses ASP flooding has a serious foul water problem. So, scaling conditions were analyzed to discuss the petroleum production and oil–gas–water treatment. In the flooding process in stratum, scaling in the ASP flooding is because of chemical condition changes. The silica and aluminum irons in the rocks are dissolved in the formation water. It breaks the original ion balance and results in reservoir scaling and damage. Several influencing factors were analyzed by investigating scaling conditions in ASP flooding.
