Experiment Research on the Nature of Carbon Dioxide Flooding Produced Water by Aeration Method

摘要

In order to further explore the effective water treatment technology and the characteristics of water quality with high carbon dioxide for low-ultra low permeability oil fields in the peripheral part of Daqing, a series of experiments are used to evaluate the effect of aeration process for removing the C02 from oily wastewater and investigate the oil-water separation property by a small simulation test system. The results show that the properties of C02 flooding produced water, such as salinity and corrosion rate, may be affected due to the increasing carbon dioxide content. The aeration is an effective method for reducing the acidity and the corrosion products of the C02 flooding produced water.
