Oil Chemical Flooding

Chemical flooding oilfield waterflood oil is applied to the first method consists of surfactant Food dehydrator, polymer flooding and alkaline flooding three. At present, the application of chemical flooding tends to polymer flooding or polymer + base + surfactant flooding (ASP), polymer flooding can increase oil recovery by about 10%, ASP flooding technology can improve recovery about 20%. Since the "Plan" beginning polymer technology research, it has been experienced pilot test phase, industrial test phase, and eventually developed into large-scale application stage, the current scale from oil expeller and application are in a leading position in our country. At present, China has been on the ASP flooding for a more in-depth research and site promotion, from technical measures and scale has reached the international advanced level.
